＜Overview＞
A first lighting device according to one aspect of the embodiment includes a long fixture body, a normal lighting device having a normal power supply unit, and an emergency lighting device having an emergency power supply unit, the fixture body having a through hole for inserting an input wiring for receiving power from a commercial power supply at the center between a first end which is one end in the longitudinal direction and a second end which is the other end in the longitudinal direction, the normal power supply unit being disposed between the first end and the through hole, and the emergency lighting device being disposed between the second end and the through hole and adjacent to the short side direction of the fixture body. As a result, by shifting the positions of the emergency power supply unit, the emergency power supply unit, and the through hole in the longitudinal direction and the short side direction, crowding can be suppressed, and interference between electrical equipment and wiring can be prevented.

In a second lighting device according to another aspect of the embodiment, in the first lighting device, the fixture body is provided with a terminal block that connects to the input wiring, the normal power supply unit is configured to be connectable to the terminal block via a first wiring, and the emergency power supply unit is configured to be connectable to the terminal block via a second wiring, and the terminal block is disposed between an imaginary plane that passes through the end of the normal power supply unit on the through hole side and is perpendicular to the longitudinal direction, and an imaginary plane that passes through the end of the emergency power supply unit on the through hole side and is perpendicular to the longitudinal direction. This allows the first wiring and the second wiring to be shorter than when the terminal block is not disposed between the imaginary plane on the through hole side of the normal power supply unit and the imaginary plane on the through hole side of the emergency power supply unit.

A third lighting device according to another aspect of the embodiment is the second lighting device, wherein the terminal block has a second output connection port for connecting to the second wiring, the emergency power supply unit has a second input connection port for connecting to the second wiring, and the second input connection port of the emergency power supply unit faces in a direction opposite to the second output connection port of the terminal block in the longitudinal direction. This makes it possible to shorten the second wiring compared to a case in which the second input connection port and the second output connection port are provided so as to face in the same direction in the longitudinal direction. As a result, the electrical equipment is prevented from becoming complicated. In addition, "in the longitudinal direction, the second input connection port faces the direction opposite the second output connection port" includes a state in which the second input connection port and the second output connection port overlap in whole or in part when the second input connection port is viewed (see-through) in the longitudinal direction from the side opposite the side where the second output connection port is located with respect to the second input connection port, and a state in which the second input connection port A and the second output connection port B do not overlap and the second input connection port A and the second output connection port B can be seen.

A fourth lighting device according to another aspect of the embodiment is the third lighting device, in which the fixture body has a second through hole for inserting the second wiring between a virtual plane that passes through the second output connection port of the terminal block and is perpendicular to the longitudinal direction, and a virtual plane that passes through the second input connection port of the emergency power supply unit and is perpendicular to the longitudinal direction. This prevents the second wiring from becoming longer than when the second through hole is not between the virtual plane on the second output connection port side and the virtual plane on the second input connection port side.

A fifth lighting device according to another aspect of the embodiment is any one of the first to fourth lighting devices, in which the emergency lighting device has an emergency light source unit and a battery unit, and the battery unit is removably held by an emergency light source attachment that attaches the emergency light source unit to the device body. This eliminates the need for a part for providing the battery unit, and can reduce the number of parts. It can also contribute to reducing the weight of the emergency light source unit.
A sixth lighting device according to another aspect of the embodiment is the fifth lighting device, wherein the fixture body has a recessed portion into which the normal lamp is fitted and an extension portion extending in a short direction from an opening end of the recessed portion, and the emergency light source attachment device is attached to the extension portion. This allows heat from heat generating components such as the emergency light source unit and the battery unit to escape to the extension portion, thereby improving heat dissipation.

The flat plate portion 501 has a screw hole 501d into which a screw 509 (see FIG. 7B ) from the emergency light source unit 51 is screwed. In this way, the emergency light source unit 51 is attached to the flat plate portion 501.
The emergency light source mounting fixture 50 has a bent portion 505 that is bent upward from an end portion on the long side of the flat plate portion 501. This reinforces the flat plate portion 501.

6, the emergency light source mounting device 50 is attached to the fixture body 3 to which the fixing devices 61, 62 are attached. Alternatively, the emergency light source mounting device 50 is attached to the fixing devices 61, 62 attached to the fixture body 3. Note that the fixing devices 61, 62 also function as reinforcing devices when the fixture body 3 does not have sufficient mechanical properties.
6B, the fixing members 61 and 62 are formed by pressing a single metal plate, for example. The fixing members 61 and 62 may be formed of resin.
The fixing devices 61, 62 have abutment portions 611, 621 that abut against the upper surface of the equipment side base 30, and mounting portions (614b, 624a) for mounting the emergency light source mounting device 50.

The contact portions 611, 621 are configured to contact the bottom plate portion 311 of the appliance side base 30, at least one of the pair of side plate portions 313, and the extension portion 302 on the side of at least one of the side plate portions 313. In other words, the contact portions 611, 621 have bottom plate facing portions 612, 622, side plate facing portions 613, 623, and extension facing portions 614, 624.
The contact portions 611, 621 have semicircular notches 612a, 622a corresponding to the raised portion 301g around the through hole 301a of the instrument body 3. The contact portions 611, 621 have through holes 612b, 622b for rivets 69 that fix the fixing devices 61, 62 to the instrument body 3. The rivets 69 pass through the through holes 612b, 622b and the through hole 301i of the instrument body 3.

The fixing devices 61 and 62 have through holes 614a and 624a in the extending opposing portions 614 and 624 for attaching the emergency light source mounting device 50. A rivet 68 is inserted into the through hole 614a of the fixing device 61. The rivet 68 is inserted into the through hole 614a of the fixing device 61, the through hole 302a of the extending portion 302 of the device body 3, and the through hole 503a of the horizontal extending portion 503 of the emergency light source mounting device 50. The through hole 624a of the fixing device 62 engages with the horizontal extending portion 504 of the emergency light source mounting device 50 after it has been inserted into the through hole 302b of the extending portion 302 of the device body 3.

(3) Inspection Switch Unit The inspection switch unit 56 receives an operation to perform a self-inspection of the emergency lighting device 5, and when a self-inspection operation is received, it transmits a signal of the operation to the emergency power supply unit 52 and displays the inspection status.
8, the inspection switch unit 56 includes an inspection module 560 having a display means (e.g., an LED) 562, an operation means (switch) 563, and a connector 564 for electrical connection mounted on an inspection board 561, and a lower inspection case 565 and an upper inspection case 566 for accommodating the inspection module 560. The lower inspection case 565 and the upper inspection case 566 form an inspection case 567 (see FIG. 7).
The inspection case 565 has a through hole 565a that allows the display means 562 and the operating means 563 to be visible and operable from the front side.
A screw structure, a rivet structure, an engagement structure, etc. can be used to connect the lower inspection case 565 and the upper inspection case 566. Here, an engagement portion (e.g., an engagement protrusion) 565b of the lower inspection case 565 engages with an engagement portion (e.g., an engagement hole portion) 566a of the upper inspection case 566.
The inspection case 567 (here, the inspection lower case 565) has an attachment portion for attaching the inspection switch unit 56 to the emergency light source mounting fixture 50 as shown in Fig. 5(a). For attachment, a screw structure, a rivet structure, an engagement structure, or the like can be used. Here, a screw 569 inserted through a through hole in the protruding portion 565c of the inspection lower case 565 is screwed into a screw hole 501f in the flat plate portion 501 of the emergency light source mounting fixture 50 shown in Fig. 7.

(4) Emergency lower cover As shown in FIG. 5 , the emergency lower cover 57 has a rectangular parallelepiped lower cover main body 570 that is long in the longitudinal direction and open at the top, and mounting portions for attaching the emergency lower cover 57 to the appliance main body 3 and the fixing devices 61, 62.
3A, the lower cover body 570 is provided close to the lower surface of the extension 302 of the instrument body 3. For this reason, the upper edge of the lower cover body 570 is inclined downward as it moves outward in the short side direction.
The bottom plate portion 573 of the lower cover main body portion 570 is provided with a through hole 573 a for the emergency light source unit 51 and a through hole 573 b for the inspection switch unit 56 .
The emergency lower cover 57 has horizontal extensions 575, 572 that are bent in the longitudinal direction from the upper end of the side plate portion 574 on the short side. The emergency lower cover 57 can be attached to the appliance body 3 (fixing devices 61, 62) using a screw structure, a rivet structure, or an engagement structure. Here, a screw structure and an engagement structure are used. That is, the screw hole 571 of the horizontal extension 575 functions as an attachment portion into which the screw 67 is screwed, and the horizontal extension 572 functions as an attachment portion as an engagement structure. As shown in FIG. 6, in a state in which the horizontal extension 572 is inserted through the through hole 302d of the appliance body 3 and engaged with the through hole 624b that functions as the attachment portion of the fixing device 62, the screw 67 is inserted through the through hole 614b of the fixing device 61 and the through hole 302c of the appliance body 3 and screwed into the screw hole 571 of the horizontal extension 575 of the emergency lower cover 57.

(5) Emergency power supply unit The emergency power supply unit 52 has an emergency power supply circuit 520 for generating the lighting power for the emergency light source unit 51, generating the driving power for the inspection switch unit 56, and generating the driving power for a control unit such as executing an inspection program by operating the inspection switch unit 56.
As shown in FIG. 11 , the emergency power supply circuit 520 is configured by mounting a plurality of electronic components 521 including a control unit on an emergency power supply board 522 .
As shown in Figures 10 and 11, the emergency power supply unit 52 is provided with a connection terminal block 523 for electrically connecting to the terminal block 32, a connector 524B for connecting to the battery unit 54 via wiring 549 (see Figure 9) and 547, a connector 524A for connecting to the inspection switch unit 56 via wiring 568, and a connector 524C for connecting to the emergency light source unit 51 via wiring 519, which are provided on the emergency power supply board 522.
In addition, the wiring 568 for the inspection switch unit 56 and the wiring 519 for the emergency light source unit 51 are inserted through a ring-shaped bush 303 (see Figure 6(a)) that fits into the through hole 302e shown in Figure 9(b).
The emergency power supply circuit 520 is attached to an emergency power supply base 526 via an insulating sheet 527, and is covered by an emergency power supply cover 529 with an insulating sheet 528 interposed therebetween.

The emergency power supply board 522 has a rectangular shape, and its longitudinal direction coincides with the longitudinal direction of the lighting device X. The connection terminal block 523 and the connectors 524A, 524B, and 524C are arranged on both ends in the longitudinal direction. The second input connection port 523a of the connection terminal block 523 faces the terminal block 32 and is provided on a surface perpendicular to the longitudinal direction. The connection terminal block 523 is provided on the end of the emergency power supply board 522 that is closer to the terminal block 32. The connection terminal block 523 is arranged so as to be located outside the emergency power supply cover 529, as shown in FIG. 9(a) and FIG. 10(a). This makes it easy to connect the second wiring to the terminal block 32.
Note that, on the emergency power supply board 522, the connection terminal block 523 may be arranged so that the second input connection port 523a faces the terminal block 32. Even in this case, the second wiring can be easily connected to the terminal block 32.
As shown in the enlarged view of Fig. 10A, the connectors 524A, 524B, and 524C are disposed so as to be located outside the emergency power supply cover 529. This allows easy connection of wiring 519, 568, and 547 to the battery unit 54, inspection switch unit 56, and emergency light source unit 51, as shown in Fig. 11A.
7, the wiring 519 is connected to a connector 519A for connecting to the connector 524C, and the wiring 568 is connected to a connector 568A for connecting to the connector 524A. As shown in Fig. 11, the wiring 547 has a connector 547A at one end for connecting to the connector 524B, and a connector 547B at the other end for connecting to the connector 548 provided on the power supply support 530. Also, in Fig. 11 and other figures, the wiring is shown as a single wire so that the connection of the wires can be seen.

As shown in FIG. 11, the emergency power supply base 526 has a rectangular flat plate portion 526a and a pair of long side plate portions 526b extending downward from the long side edges of the flat plate portion 526a.
The emergency power supply base 526 has cut-and-raised portions 526c and through holes 526d formed in a flat plate portion 526a. The cut-and-raised portions 526c are located at both ends in the longitudinal direction and regulate the movement of the insulating sheet 527 in the longitudinal direction (see FIG. 10A).
The long side plate portion 526b has cut-and-raised portions 526e spaced apart in the longitudinal direction. A bent portion 526g is formed in an area spanning the flat plate portion 526a and the long side plate portion 526b, and a screw hole 526h is formed in the flat portion. A screw 525 passing through a through hole in the emergency power supply board 522 screws into the screw hole 526h. The end of the long side of the emergency power supply board 522 is supported by the cut-and-raised portions 526e of the long side plate portion 526b.

The emergency power supply cover 529 has a cover body 529a which is open at the top and has a long rectangular shape along the longitudinal direction of the lighting device X, a plurality of upwardly facing upper cut-out portions 529c provided on the long side plate portion 526b of the cover body 529a, a plurality of downwardly facing lower cut-out portions 529d provided on the long side plate portion 529b of the cover body 529a, and a notch portion 529f provided on one of the short side plate portions 529e of the cover body 529a.
Here, there are three upper cut-and-raised portions 529c and two lower cut-and-raised portions 529d. When the emergency power supply cover 529 is attached to the emergency power supply base 526, the upper cut-and-raised portions 529c abut against the lower end of the long side plate portion 526b of the emergency power supply base 526, and the lower cut-and-raised portions 529d engage (fit) with the openings of the cut-and-raised portions 526e of the long side plate portion 526b of the emergency power supply base 526.
The notch 529f of the short side plate portion 529e is for the connection terminal block 523 provided on the emergency power supply board 522.

(6) Emergency Power Supply Mounting Tool As shown in FIG. 10 , the emergency power supply mounting tool 53 has a power supply support 530 that supports the emergency power supply unit 52, and a fixing tool 555 for fixing the power supply support 530 to the equipment body 3.

(6-1) Power Supply Support The power supply support 530 has a rectangular flat plate portion 531 extending in the longitudinal direction, long side plate portions 532 and 533 extending downward from the long side ends of the flat plate portion 531, and short side plate portions 534 and 535 extending downward from the short side ends of the flat plate portion 531. The power supply support portion here is constituted by the flat plate portion 531.
The flat plate portion 531 has an attachment portion for attaching the emergency power supply unit 52 to the flat plate portion 531. For attachment, a screw structure, a rivet structure, an engagement structure, or the like can be used. Here, a screw and a nut are used. The screw 538 is inserted through the through hole 526d (see FIG. 11 ) of the emergency power supply base 526 of the emergency power supply unit 52 and the through hole 531a of the flat plate portion 531, and is screwed into the nut 537 on the upper surface of the flat plate portion 531.
A connector 548 for connecting to the connector 545 of the battery unit 54 is attached to a through hole (not shown in FIG. 10 due to the connector 545) in the short side plate portion 535 on the side remote from the terminal block 32. The battery unit 54 is connected to the connector 524B of the emergency power supply unit 52 via a wire 549, a connector 545, a connector 548, a connector 547B, a wire 547, and a connector 547A (see FIG. 11(a)).
The long side plate portion 532 located on the outer side in the short direction has a notch portion 532a that leaves both ends and the upper end in the longitudinal direction. This allows for weight reduction. The long side plate portion 532 has mounting portions at both ends 532b for detachably mounting the emergency upper cover 58 described below. A screw structure, an engagement structure, or the like can be used for mounting. Here, a screw 589 (see FIG. 5) is used, and the mounting portion is composed of a through hole 532c and a nut 532d attached to the back side of the through hole 532c.

(6-2) Fixture There are two fixtures 555 here, which are spaced apart in the longitudinal direction. The fixtures 555 are manufactured, for example, by pressing a metal plate. The fixture 555 has an instrument-side mounting portion 556 that is attached to the instrument main body 3 side, and a power-source-side mounting portion 557 that is attached to the power-source support body 530 side. Here, there is a step between the instrument-side mounting portion 556 and the power-source-side mounting portion 557, and this step functions as a connecting portion 558 that connects the two portions.

As shown in Fig. 5(b), the tool side mounting part 556 faces the tool side base 30 of the tool body 3. For mounting, a screw structure, a rivet structure, an engagement structure, or the like can be used. Here, a rivet 539 is used, and the tool side mounting part 556 has one or a plurality of (e.g., two) through holes 556a for the rivet 539. The through holes 556a are provided at intervals in the short direction.
As shown in Fig. 9(b), the power supply side mounting portion 557 faces the flat plate portion 531 of the power supply support body 530. For mounting, a screwing design, a rivet structure, an engagement structure, welding, or the like can be used. Here, welding is used. The portion to be welded on the power supply side mounting portion 557 is indicated by "557a", the portion to be welded on the power supply support body 530 is indicated by "531c", and the welded portion in Fig. 9 is indicated by "557b". There may be one or more welding locations, and here welding is performed at two locations spaced apart in the longitudinal direction.
The connecting portion 558 is bent downward from the short-side edge of the appliance-side attachment portion 556. The bending angle corresponds to the angle between the bottom plate portion 311 and the side plate portion 313 of the appliance-side base 30 of the appliance main body 3. This causes the connecting portion 558 to face (abut) against the side plate portion 313 of the appliance-side base 30, as shown in Fig. 5(b), making it easy to position the emergency power supply mounting device 53 relative to the appliance main body 3.

10 , the battery unit 54 includes a rechargeable storage battery (not shown), a battery case 541 that houses the storage battery, and wiring 549 and a connector 545 that are provided in the battery case 541 and are used for electrical connection to the emergency power supply unit 52. The connector 545 is connected to a connector 548 on the short side plate portion 535 of the power supply support body 530.
The battery unit 54 is provided on the fixture 61 as shown in FIG. 5. Specifically, as shown in FIG. 10, the battery unit 54 is placed on a horizontal portion 615 extending horizontally from an edge of the extended facing portion 614 of the fixture 61. The fixture 61 has a holding portion for holding the battery unit 54. The holding portion here has a cut-and-raised portion 615a provided at the connecting portion between the extended facing portion 614 and the horizontal portion 615, a bent portion 615b formed at the end of the horizontal portion 615 opposite to the extended facing portion 614, and an extension portion 615c extending upward from the longitudinal edge of the horizontal portion 615 opposite to the emergency power supply unit 52. This makes it possible to prevent the battery unit 54 arranged on the fixture 61 from falling off the horizontal portion 615. In addition, the battery unit 54 can be inserted and removed from the holding portion from the short side with the emergency upper cover 58 removed. This allows, for example, when installing the lighting device X, to remove the emergency upper cover 58 and connect the connector 545, etc., before placing the battery unit 54, thereby improving operability during installation.

1, the emergency upper cover 58 covers at least the emergency power supply unit 52. Here, the emergency upper cover 58, together with the power supply support 530, houses the emergency power supply unit 52. In other words, the emergency upper cover 58 and the power supply support 530 can be said to be an emergency power supply case that houses the emergency power supply unit 52.
The emergency upper cover 58 also covers the battery unit 54, as shown in FIG.
The emergency upper cover 58 includes a rectangular long side plate portion 581 extending in the longitudinal direction and the up-down direction, a short side plate portion 582 extending inward in the lateral direction from the longitudinal end edge of the long side plate portion 581, and a bottom plate portion 583 extending horizontally from the lower end of the long side plate portion 581. Both longitudinal ends of the bottom plate portion 583 are connected to the short side plate portion 582. This improves the mechanical properties of the emergency upper cover 58.
The long side plate portion 581 has an attachment portion 581a for removably attaching the emergency upper cover 58 to the power supply support body 530. A screwing structure, an engagement structure, or the like can be used for the attachment. Here, a screw 589 is used for attachment, and the long side plate portion 581 has a through hole as the attachment portion 581a. The screw 589 is inserted through the through hole of the power supply support body 530 and is screwed into a nut 532d (see FIG. 10(a)) on the back side of the through hole.
1, the emergency upper cover 58 is disposed close to the upper surface of the device body. For this reason, the lower part of the short side plate portion 582, which is opposite to the long side plate portion 581, is cut out in an inclined manner. This can improve the design.
The emergency upper cover 58 is provided with a cover plate 59 that covers the battery unit 54 .

5. Layout The layout will be described with reference to Fig. 12. Fig. 12 is a diagram of the device body cut at the center in the short direction and viewed from above. Note that the power supply support 530 has been removed so that the emergency power supply unit 52 can be seen.

The fixture body 3 has a through hole 301b for inserting input wiring to connect to a commercial power source, at the center C between a first end A, which is one longitudinal end of the fixture body 3, and a second end B, which is the other longitudinal end.
In addition, the normal power supply unit 12 of the normal lighting fixture 1 is arranged between the first end A and the through hole 301b, and the emergency power supply unit 52 of the emergency lighting fixture 5 is arranged between the through hole 301b and the second end B, adjacent to each other in the short direction of the fixture body 3.
As a result, the normal power supply unit 12 and the emergency power supply unit 52 are located on either side of the through hole 301b in the longitudinal direction, preventing the normal power supply unit 12 and the emergency power supply unit 52 from being crowded together. This also prevents interference between the first wiring, the second wiring, and the like. Furthermore, with the above arrangement, the center of gravity of the lighting device X is located at the position "G1" in Fig. 12. In this way, the center of gravity is located between a pair of hanging bolts, preventing the load from being biased toward one of the hanging bolts.
Furthermore, since the emergency power supply unit 52 is offset in the short side direction relative to the area (recessed portion 301) in the fixture body 3 that holds the regular lighting fixture 1, interference with the second wiring can be easily prevented.
1, the emergency power supply unit 52 is adjacent to and spaced apart in the short side direction from the recessed portion 301 that houses the upper portion of the normal lighting fixture 1 in the fixture body 3, but it may be adjacent to or in close contact with the recessed portion 301. In other words, it is sufficient that the recessed portion 301 of the fixture body 3 and the emergency power supply unit 52 are adjacent but not overlapped when the lighting device X is viewed from above.

The terminal block 32 of the fixture body 3 is connected to the input wiring introduced into the fixture body 3 from the through hole 301b. The terminal block 32 is disposed between a virtual surface D (the end here is the first input connection port 123a of the normal power supply unit 12) that passes through the end of the normal power supply unit 12 on the through hole 301a side and is perpendicular to the longitudinal direction, and a virtual surface E (the end here is the second input connection port 523a of the emergency power supply unit 52) that passes through the end of the emergency power supply unit 52 on the through hole 301b side and is perpendicular to the longitudinal direction. This allows the first wiring connecting the terminal block 32 and the normal power supply unit 12 and the second wiring connecting the terminal block 32 and the emergency power supply unit 52 to be short, thereby preventing the wiring from becoming complicated. In addition, the first wiring and the second wiring are shortened, making it easier to arrange the first wiring and the second wiring. In addition, in the terminal block 32, the positional relationship between the input connection port 321 for the input wiring, the first output connection port 322 for the first wiring, and the second output connection port 323 for the second wiring is not particularly limited.
In Fig. 12, the imaginary planes D and E are shown as lines because they show the state of the instrument body 3 as viewed from above. However, when the instrument body 3 is viewed from the short side direction, the imaginary planes D and E are formed as planes that extend perpendicularly to the up-down direction of the instrument body 3 as shown in Fig. 13(a).

The second input connection port 523a for connecting with the second wiring in the emergency power supply unit 52 is arranged to face in the longitudinal direction in a direction opposite to the second output connection port 323 for connecting with the second wiring for the emergency power supply unit 52 in the terminal block 32. This allows the second wiring to be short, preventing the wiring from becoming complicated. Also, the second wiring can be easily connected.
Similarly, configurations that can shorten the second wiring include a pattern in which either the second input connection port 523a or the second output connection port 323 is arranged so as to face opposite each other in the short side direction, and a pattern in which the second input connection port 523a and the second output connection port 323 are arranged so as to face in directions that face opposite each other in the short side direction.

The device body 3 has a second through hole 313a for inserting the second wiring between a third imaginary plane J that passes through the second output connection port 323 of the terminal block 32 and is perpendicular to the longitudinal direction, and an imaginary plane H that passes through the second input connection port 523a of the emergency power supply unit 52 and is perpendicular to the longitudinal direction, as shown in FIG. 13. The second through hole 313a is provided in the side plate portion 313 that constitutes the recessed portion 301. This allows the second wiring to be shorter than when there is no second through hole 313a. In addition, the shortening of the second wiring makes it easier to arrange the second wiring. The second through hole 313a is provided in the side plate portion 313, but may be provided in the bottom plate portion 311 as long as it is between the imaginary planes H and J. However, if the arrangement of the second wiring is not taken into consideration, the second through hole 313a may be provided in another portion.

Considering the length of the wiring in the emergency lighting device 5 attached to the fixture body 3, it is preferable that the emergency lighting device 5 at least includes an emergency light source unit 51 and an emergency power supply unit 52, with the emergency light source unit 51 being disposed on the front (lower surface) of the fixture body 3 and the emergency power supply unit 52 being disposed on the rear (upper surface) of the fixture body 3 in a position overlapping the emergency light source unit 51 in the front-to-back direction. This brings the emergency light source unit 51 and the emergency power supply unit 52 closer to each other, allowing the wiring to be shortened.
When the emergency lighting device 5 includes a battery unit 54 that supplies power during a power outage, it is preferable that the battery unit 54 is disposed adjacent to the emergency power supply unit 52 on the rear surface (top surface) of the device body 3. This brings the battery unit 54 and the emergency power supply unit 52 closer to each other, allowing the wiring to be shorter. Note that, in the case of a lighting device that takes into consideration the wiring within the emergency lighting device 5, the position of the terminal block 32, the position of the input wiring, etc. are not particularly limited.

When the emergency lighting device 5 includes the heavy emergency power supply unit 52, it is preferable to provide a fixing device (fixing part) 555 that is arranged on the upper surface of the device body 3 and also functions as a reinforcing device for the device body 3, and a power supply support (power supply support part) 530 that is attached to the fixing device (fixing part) 555 and supports the emergency power supply unit 52. This allows the device body of a lighting device that does not include an emergency lighting device 5 to be used. In addition, by using the fixing device (fixing part) 555 and the power supply support (power supply support part) 530, for example, even if the emergency power supply unit 52 is arranged above the extension part 302, the emergency power supply unit 52 can be provided without forming a through hole or a cut part in the extension part 302 (excluding the through hole for wiring), that is, without deteriorating the mechanical properties of the extension part 302 and the device body 3. Note that, when focusing on the installation of the emergency power supply unit 52, the terminal block 32, the length of the wiring, the position of the input wiring, etc. are not particularly limited.

Second Embodiment
14, the lighting device Y of the second embodiment includes a regular lighting fixture 1, a fixture body 2003, and an emergency lighting fixture 2005. The regular lighting fixture 1 has the same configuration as that of the first embodiment, and the same reference numerals are used, and the description thereof will be omitted.

1. Instrument Body The instrument body 2003 is a so-called inverted Fuji type.
The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.
As shown in FIG. 15, the fixture body 2003 has a normal use fixture mounting portion for mounting the normal use fixture 1, an emergency fixture mounting portion for mounting the emergency fixture 2005, and a fixture mounting portion for mounting to an installation surface.
The fixture body 2003 has a fixture side base 2030 , a terminal block 32 , a regular lighting fixture attachment device 34 for attaching the regular lighting fixture 1 , and a terminal cover 2036 .

The appliance side base 2030 has a recessed portion 2301 that recesses upward and extends in the longitudinal direction, and a pair of extension portions 2302 that extend outward in the lateral direction from both ends of the recessed portion 2301. The recessed portion 2301 has a bottom plate portion 2311 and a pair of side plate portions 2313. The pair of extension portions 2302 extend while inclining obliquely upward. For this reason, the extension portions 2302 can also be called inclined plate portions.
As in the first embodiment, the upper part of the service lamp 1 is fitted into the recessed portion 2301. The extension portion 2302 has the function of reflecting light from the service lamp 1 downward.
The terminal block 32 and the regular lamp fixture 34 are attached to the bottom plate portion 2311 of the recessed portion 2301, and has a through hole 2301b for input wiring, a through hole 2310a for a hanging bolt (not shown), and through holes for attaching the terminal block 32 and the regular lamp fixture 34, etc.
An emergency lighting device 2005 is provided on the underside of the fixture-side base 2030, more specifically, on the underside of one of the extensions 2302. The emergency lighting device 2005 and the service power supply unit 12 of the service lighting device 1 are located on either side in the longitudinal direction, sandwiching a through hole 2301b for input wiring.

16, the emergency lighting device 2005 includes an emergency light source unit 51, an emergency power supply unit 52, a battery unit 54, and an inspection switch unit 56. These units are provided on the lower surface of the fixture body 2003 in the second embodiment.
The emergency lighting device 2005 includes an emergency light source attachment device 2050 for attaching the emergency light source unit 51 to the device body 2003. The battery unit 54 and the inspection switch unit 56 are attached to the emergency light source attachment device 2050 here. The emergency power supply unit 52 is attached directly to the device body 2003.
As shown in Figure 15, the emergency lighting device 2005 is equipped with an emergency lower cover 2057 that covers from below, except for the lens portion 511a of the emergency light source unit 51 and the display means 562 and operating means 563 of the inspection switch unit 56, and lower cover mounting fixtures 2058, 2059 for mounting the emergency lower cover 2057 to the device main body 3, as shown in Figure 16.
The emergency power supply unit 52, the emergency light source mounting fixture 2050, and the lower cover mounting fixtures 2058 and 2059 are attached by utilizing a pair of fixing fixtures 2061 and 2062 arranged at a distance in the longitudinal direction on the upper surface of the fixture body 2003. The fixing fixtures 2061 and 2062 may be components of the fixture body 2003 or may be components of the emergency lighting fixture 2005. The fixing fixtures 2061 and 2062 also function as reinforcing fixtures when the fixture body 2003 does not have sufficient mechanical properties.

(1) Emergency Power Supply Unit The emergency power supply unit 52 is attached to the extension portion 2302 of the fixture body 2003 using fasteners 2061, 2062 as shown in Figures 16 and 17 .

16 and 17, the fixtures 2061 and 2062 are formed, for example, by pressing a single metal plate. By using the fixtures 2061 and 2062, the instrument side base 2030 can be partially reinforced and the overall plate thickness of the instrument side base 2030 can be reduced. This allows for weight reduction.
The fixing devices 2061 and 2062 have contact portions 2611 and 2621 that contact the upper surface of the appliance side base 2030 and an attachment portion for attaching the emergency power supply unit 52 .

The abutment portions 2611, 2621 have bottom plate facing portions 2612, 2622 that face the bottom plate portion 2311 of the appliance side base 2030, side plate facing portions 2613, 2623 that face at least one of a pair of side plate portions 2313, and extension facing portions 2614, 2624 that face the extension portion 2302 on the side of at least one of the side plate portions 2313.
The bottom plate facing portion 2612 has a notch 2612a corresponding to the mounting portion 2011a of the terminal block 32 to the fixture body 2003. The bottom plate facing portion 2622 has a notch 2622a corresponding to the through hole 2011b of the fixture body 2003.
The bottom plate opposing portions 2612 and 2622 have through holes 2612b and 2622b for a rivet 2069 that fixes the fixing devices 2061 and 2062 to the fixture body 2003. The rivet 2069 is inserted through the through holes 2612b and 2622b and the through hole 2301i of the fixture body 2003.
The bottom plate facing portion 2622 of the fixture 2062 has a through hole 2622c corresponding to the convex portion 2311d of the device body 2003 (bottom plate portion 2311), and the bottom plate facing portion 2612 of the fixture 2061 also has a corresponding through hole 2612c.

The fixtures 2061 and 2062 have an attachment portion for attaching the emergency power supply unit 52. For attachment, a screw structure, a rivet structure, an engagement structure, etc. can be used, and here, a screw 538 is used. The screw 538 is inserted from below through the through hole 526d (see FIG. 11) of the emergency power supply base 526 of the emergency power supply unit 52, the through hole 2302a of the extension part 2302 of the fixture body 2003, and the through holes 2614b and 2624a of the fixtures 2061 and 2062, and then screwed into the nut 2068 on the back side of the through holes 2614b and 2624a. As a result, the emergency power supply unit 52 is attached to the fixture body 2003. The attachment portion is composed of the through holes 2614b and 2624a and the nut 2068.
The second wiring 2549 that connects the emergency power supply unit 52 and the terminal block 32 is inserted through a bush 2309 provided in a through hole of the fixture body 2003. The fixture 2061 has a through hole 2614d for the bush 2309.

(2) Emergency Light Source Unit, etc. The emergency light source unit 51, the inspection switch unit 56 and the battery unit 54 are attached to the extension portion 2302 of the fixture body 2003 using an emergency light source mounting fixture 2050 and a fixing fixture 2062, as shown in Figures 16 and 18.

(2-1) As shown in FIG. 18 , the emergency light source mounting fixture 2050 has a light source support portion that supports the emergency light source unit 51, and a light source fixing portion for fixing the emergency light source unit 51 (emergency light source mounting fixture 2050) to the device body 3.
The emergency light source mounting fixture 2050 has a flat plate portion 2501 extending in the longitudinal direction, an upper extension portion 2502 extending upward from one longitudinal end of the flat plate portion 2501 (the side opposite to the through hole 2301b (see Figure 15)), and a horizontal extension portion 2503 extending from the upper end of the upper extension portion 2502 toward one longitudinal end side.
Here, the light source support portion is constituted by a flat plate portion 2501 , and the attachment portion is constituted by a through hole 2503 a of a horizontal extension portion 2503 .

The flat plate portion 2501 has through holes 2501b, 2501c into which the rod-shaped portions 515c, 512d of the emergency light source unit 51 fit, and a screw hole 2501d for a screw 509 for fixing the emergency light source unit 51 to the flat plate portion 2501.
The emergency light source mounting fixture 2050 has a bent portion 2508 that is bent upward from the end portion on the long side of the flat plate portion 2501. This reinforces the flat plate portion 501.

The flat plate portion 2501 has a through hole 2501 a for the wiring 519 that connects the emergency light source unit 51 and the emergency power supply unit 52 .
The upper side of the inspection switch unit 56 fits into the through hole 2501a, and in this state, the inspection switch unit 56 is attached to the flat plate portion 2501. A screw structure, a rivet structure, or an engagement structure can be used for attachment, and here, a screw 569 is used. The screw 569 is inserted through the through hole 565d of the inspection switch unit 56 and screwed into the screw hole 2501e of the flat plate portion 2501. The screw hole 2501e constitutes an attachment portion for attaching the inspection switch unit 56 to the emergency light source fixture 2050.

The upper end of the upper extension 2502 and the lateral extension 2503 are inclined so as to abut against the extension 2302 of the device body 2003 when the flat plate 2051 is in a horizontal position. A screw 2509 is inserted into the through hole 2503a of the lateral extension 2503. The upper extension 2502 is provided with a through hole 2502a for wiring (fixing the connector 548).

(2-2) Fixture As described above, the fixture 2062 has a mounting portion for mounting the emergency light source mounting device 2050 in addition to the abutment portion 2621 and the mounting portion 2624a. For mounting, a screw structure, a rivet structure, an engagement structure, or the like can be used, and here, a screw 2509 is used. The screw 2509 is inserted through the through hole 2503a of the horizontal extension portion 2503 of the emergency light source mounting device 2050 and the through hole 2302b of the extension portion 2302 of the fixture body 2003, and then screwed into the screw hole 2624b of the fixture 2062. In this way, the emergency light source mounting device 2050 is mounted to the fixture body 2003. The mounting portion is constituted by the screw hole 2624b.

(2-3) Battery Unit The battery unit 54 is attached to the fixture body 2003 by using the emergency light source mounting fixture 2050. The emergency light source mounting fixture 2050 has a flat plate portion 2504 on which the battery unit 54 is placed, an inner upper extension portion 2505 that extends upward from the other end side of the flat plate portion 2504 in the longitudinal direction and connects to the lateral extension portion 2503, a bent portion 2506 that bends obliquely upward from the outer end of the short side of the flat plate portion 2504, and an outer upper extension portion 2507 that extends upward from one end of the bent portion 2506 in the longitudinal direction.
That is, the inner upper extension 2505, the outer upper extension 2507, and the bent portion 2506 form a holding portion that holds the battery unit 54. The bent portion 2506 is approximately parallel to the extension 2302 of the fixture body 2003, and the battery unit 54 can be removed from the gap between the upper end of the bent portion 2506 and the fixture body 2003 with the emergency lower cover 2057 removed. Also, with the emergency lower cover 2057 removed, the battery unit 54 can be inserted and removed from the holding portion from the short side direction. This allows, for example, the battery unit 54 to be positioned after removing the emergency lower cover 2057 and connecting the connector 545 when installing the lighting device Y, improving operability during installation.

(3) Emergency Lower Cover The emergency lower cover 2057 is detachably attached to lower cover mounting fixtures 2058, 2059 which are attached using a pair of fasteners 2061 spaced apart in the longitudinal direction, as shown in Figures 16 and 19 .

(3-1) Emergency Lower Cover The emergency lower cover 2057 has a lower cover body 2571 that is open at the top and has a rectangular parallelepiped shape that is long in the longitudinal direction.
The bottom plate 2572 of the lower cover main body 2571 has a through hole 2572a for the lens portion 511a of the emergency light source unit 51, a through hole 2572b for the display means 562 and the operation means 563 of the inspection switch unit 56, and a through hole for a screw 2579 for detachably attaching the emergency lower cover 2057. Although the through holes are not shown in FIG. 16 because of the screws 2579, they are provided at both ends in the longitudinal direction.
The upper end of the lower cover body 2571 is inclined so as to come into contact with the inclined extension portion 2302 of the device body 2003 when the bottom plate portion 2572 is in a horizontal state.

(3-2) Lower cover mounting fixture As shown in FIG. 19 , the lower cover mounting fixture 2058, 2059 has a lower horizontal extension portion 2581, 2591 extending horizontally, an upper extension portion 2582, 2592 extending upward from the longitudinal outer ends of the lower horizontal extension portions 2581, 2591, and an upper horizontal extension portion 2583, 2593 extending horizontally from the upper ends of the upper extension portions 2582, 2592.
The upper ends of the upper extensions 2582, 2592 and the upper horizontal extensions 2583, 2593 are inclined in order to abut against the inclined extension portion 2302 of the device body 2003 when the lower horizontal extensions 2581, 2591 are extended horizontally.
The upper horizontal extension portions 2583, 2593 are located on the side where the lower horizontal extension portions 2581, 2591 are present relative to the upper extension portions 2582, 2592. This allows the distance between the lower cover attachment members 2058, 2059 to be shortened.

The upper horizontal extensions 2583, 2593 have mounting portions 2583a, 2593a for mounting the lower cover mounting fixtures 2058, 2059 to the instrument body 3. For mounting, a screw structure, a rivet structure, or an engagement structure can be used, and here, screws 259, 2599 are used, and the upper horizontal extensions 2583, 2593 have through holes as the mounting portions 2583a, 2593a.
The lower horizontal extensions 2581, 2591 have attachment portions for detachably attaching the emergency lower cover 2057 to the lower cover attachment fixtures 2058, 2059. For attachment, a screw 2579 is used, as shown in Fig. 16. As shown in Figs. 16 and 19, the screw 2579 is inserted through a through hole in the bottom plate portion 2572 of the emergency lower cover 2057 and through holes 2581a, 2591a in the lower horizontal extensions 2581, 2591 of the lower cover attachment fixtures 2058, 2059, and then screwed into nuts 2588, 2598 provided on the back side of the lower horizontal extensions 2581, 2591.
As shown in FIG. 19, the lower cover attachment fixture 2058 has a notch 2583b for the bush 2039, through which the second wiring 2549 that connects the terminal block 32 and the emergency power supply unit 52 is inserted.

(3-3) Fixture As described above, the fixture 2061 has a mounting portion for mounting the lower cover fixtures 2058 and 2059, as shown in FIG. 19, in addition to the abutment portion 2611 and the mounting portion 2614b. For mounting, a screw structure, a rivet structure, an engagement structure, etc. can be used, and here, screws 2589 and 2599 are used. The screws 2589 and 2599 are inserted through the through holes 2583a and 2593a of the upper horizontal extensions 2583 and 2593 of the lower cover fixtures 2058 and 2059 and the through holes 2302c of the extension portion 2302 of the instrument body 2003, and then screwed into the screw holes 2614c of the fixture 2061. As a result, the lower cover fixtures 2058 and 2059 are attached to the instrument body 2003. The mounting portion is constituted by the screw holes 2614c.

3. Layout This will be explained with reference to Figure 20. Figure 20 is an irregular cross-sectional view seen from above, in which the emergency power supply unit 52, the terminal block 32, and the normal power supply unit 12 of the lighting fixture 1 can be seen.

The fixture body 2003 has a through hole 2301b for inserting input wiring to connect to a commercial power source, at the center 1C between a first end 1A, which is one longitudinal end of the fixture body 2003, and a second end 1B, which is the other longitudinal end.
In addition, the normal power supply unit 12 of the normal lighting fixture 1 is arranged between the first end 1A and the through hole 2301b, and the emergency power supply unit 52 of the emergency lighting fixture 2005 is arranged between the through hole 2301b and the second end 1B, adjacent to each other in the short direction of the fixture body 2003.
As a result, the normal power supply unit 12 and the emergency power supply unit 52 are located on either side of the through hole 2301b in the longitudinal direction, preventing the normal power supply unit 12 and the emergency power supply unit 52 from being crowded together. This also prevents interference between the wiring. Furthermore, with the above arrangement, the center of gravity of the lighting device Y is located at the position "G2" in Fig. 20. In this way, the center of gravity is located between a pair of hanging bolts, preventing the load from being biased toward one of the hanging bolts.
Furthermore, since the emergency power supply unit 52 is offset in the short side direction relative to the area (recessed portion 2301) that holds the regular lighting fixture 1 in the fixture body 2003, interference with wiring can be easily prevented.

The terminal block 32 of the fixture body 2003 is connected to the input wiring introduced into the fixture body 2003 from the through hole 2301b. The terminal block 32 is disposed between a virtual surface (a virtual surface passing through the first input connection port 123a of the normal power supply unit 12 and perpendicular to the longitudinal direction) 1D that passes through the end of the normal power supply unit 12 on the through hole 2301a side and is perpendicular to the longitudinal direction, and a virtual surface (a virtual surface passing through the second input connection port 523a of the emergency power supply unit 52 and perpendicular to the longitudinal direction) 1E that passes through the end of the emergency power supply unit 52 on the through hole 2301b side and is perpendicular to the longitudinal direction. This allows the first wiring connecting the terminal block 32 and the normal power supply unit 12 and the second wiring 2549 connecting the terminal block 32 and the emergency power supply unit 52 to be short, thereby preventing the wiring from becoming complicated.
20, the imaginary planes 1D and 1E are shown as lines because they show the state of the instrument body 3 as viewed from above. However, the imaginary planes 1D and 1E are formed as planes that extend perpendicularly to the up-down direction of the instrument body 2003 when the instrument body 2003 is viewed from the short side direction (see FIG. 13(a)).

The second input connection port 523a for connecting with the second wiring 2549 in the emergency power supply unit 52 is arranged to face in a direction opposite to the second output connection port 323 for connecting with the second wiring 2549 for the emergency power supply unit 52 in the terminal block 32 in the longitudinal direction. This allows the second wiring 2549 to be short, preventing the wiring from becoming complicated. Also, the second wiring 2549 can be easily connected.
Similarly, configurations that can shorten the second wiring 2549 include a pattern in which either the second input connection port 523a or the second output connection port 323 is arranged to face in the short side direction, and a pattern in which the second input connection port 523a and the second output connection port 323 are arranged to face in directions opposite to the short side direction.

When the emergency lighting device 2005 includes the heavy emergency power supply unit 52, the fixture body 2003 is provided with fasteners 2061 and 2062 that are arranged on the upper surface of the fixture body 2003 and reinforce the fixture body 2003, and the emergency power supply unit 52 is attached to the portion of the fixture body 2003 where the fasteners 2061 and 2062 are arranged. This allows the fixture body of a lighting device that does not include an emergency lighting device 5 to be used. In addition, by using the fasteners 2061 and 2062, the fixtures 2061 and 2062 and the emergency power supply unit 52 can be attached simply by providing a through hole for attachment in the fixture body 2003. Therefore, for example, even if the emergency power supply unit 52 is arranged in the extension portion 302, the emergency power supply unit 52 can be provided without providing a missing portion that would reduce the mechanical properties of the extension portion 302 or the fixture body 3. In addition, when focusing on the attachment of the emergency power supply unit 52, the terminal block 32, the length of the wiring, the position of the input wiring, etc. are not particularly limited.

The emergency lighting device 2005 includes an emergency light source unit 51, an emergency power supply unit 52, a mounting fixture (e.g., emergency light source mounting fixture 2050) for mounting at least one of the emergency light source unit 51 and the emergency power supply unit 52 to the device body 2003, and a cover (e.g., emergency lower cover 2057) for covering the emergency light source unit 51, the emergency power supply unit 52, and the mounting fixtures mounted on the device body 2003 from below. This allows for weight reduction while maintaining design, as compared to providing covers that cover the emergency light source unit 51 and the emergency power supply unit 52 separately. Note that when focusing on weight reduction of the emergency lighting device 2005, the terminal block 32, the length of the wiring, the position of the input wiring, the presence or absence of the fixing fixtures 2061, 2062, etc. are not particularly limited.

The emergency lighting device 2005 further includes an inspection switch unit 56 and a battery unit 54, and the inspection switch unit 56 and the battery unit 54 are supported by an emergency light source mounting fixture 2050 that mounts the emergency light source unit 51 to the device body 2003, and are covered by a cover (for example, an emergency lower cover 2057). This allows for weight reduction while maintaining the design, compared to providing covers that cover the inspection switch unit 56, the battery unit 54, and the emergency light source unit 51 separately.
Furthermore, since the emergency light source attachment fixture 2050 has the emergency light source unit 51, the inspection switch unit 56, and the battery unit 54 in one member, it is possible to reduce the number of parts compared to the case where attachments for attaching the respective units are provided, and this can contribute to the weight reduction of the emergency lighting fixture 2005. Note that, when focusing on the weight reduction of the emergency lighting fixture 2005, the terminal block 32, the length of the wiring, the position of the input wiring, the presence or absence of the fixing devices 2061, 2062, and the like are not particularly limited.
In addition, since the emergency light source mounting fixture 50, 2050 is fixed to the extension portion 302, 2302, heat generated from the emergency light source unit 51 and the battery unit 54 can be dissipated to the extension portion 302, 2302 via the emergency light source mounting fixture 50, 2050, thereby improving the heat dissipation effect.

Although the first and second embodiments have been described above, the present invention is not limited to these embodiments, and may be modified as follows, for example. In addition, the present invention may be combined with the modified embodiments or with each other.
Furthermore, the present invention also includes examples that are not described in the embodiments and modifications, and design changes that do not deviate from the gist of the invention.

The lighting devices X, Y were provided with fasteners 61, 62, 555, 2061, 2062 for fixing the emergency lighting device 5, 2005 to the fixture body 3, 2003, but if the mechanical characteristics of the portion of the fixture body 3, 2003 where the emergency lighting device 5, 2005 is attached are sufficient, the fasteners 61, 62, 555, 2061, 2062 may not be provided.
In the lighting devices X and Y, the emergency lighting device 5, 2005 is provided in a manner that it cannot be detached from the device body 3, 2003, but it may be provided in a manner that it can be detached.
The overall center of gravity G1, G2 of the lighting device X, Y, when viewed from above, may be between a pair of through holes 301a, 2301a in the fixture body 3, 2003 (between imaginary lines extending in the short direction through the centers of the through holes), and may be at a position other than that shown in Figures 12 and 20.

2. Fixture Body The extensions 302, 2302 are inclined downward or upward, but may extend in a direction perpendicular to the main emission direction of light.
Although the through holes 301b, 2301b for input wiring are provided in the bottom plate portions 311, 2311, they may also be provided in the side plate portions 313, 2313.
The terminal block 32 has the input connection port 321 facing the other side in the longitudinal direction and the output connection ports 322, 323 facing one side in the longitudinal direction, but the connection ports 321, 322, 323 may be facing one side and the other side in the lateral direction. Also, one of the input connection port 321 and the output connection ports 322, 323 may be on the side surface of the main body 320, and the other of the input connection port 321 and the output connection ports 322, 323 may be on the bottom surface (lower surface) of the main body 320. The terminal block 32 is provided on the bottom plate portion 311, 2311, but may be provided on the side plate portion 313, 2313. Also, the terminal block 32 may be configured to be disposed on the flat portion 100 of the regular light source base 10.
Although there are two sets (for two units) of output connection ports 322, 323 of the terminal block 32 in the above embodiment, there may be three or more sets.

3. Emergency Lighting Fixture The light source unit 51, the power supply unit 52, the battery unit 54 and the inspection switch unit 56 are arranged on one side in the short side direction of the normal lighting fixture 1, but for example, one or more of these may be arranged on the other side in the short side direction.
The emergency lighting device 5, 2005 is provided with an inspection switch unit 56, but this is not essential.
Although the light source unit 51 and the inspection switch unit 56 are disposed adjacent to each other in the above embodiment, for example, the light source unit 51 may be disposed on one side in the short side direction, and the inspection switch unit 56 may be disposed on the other side in the short side direction.

The fixing members 61, 62, 2061, 2062 are fixed to the bottom plate portions 311, 2311 of the appliance side bases 30, 2030 by using rivets 69, 2069, passing through the through holes 612b, 622b, 2612b, 2622b and the through holes 301i, 2301i of the appliance main body 3, 2003.
However, the fasteners 61, 62, 2061, 2062 may be fixed to the side plate portions 313, 2313 of the instrument body 3, 2003, or to the extension portions 302, 2302 of the instrument body 33, 2003, by a screw structure, a rivet structure, or an engagement structure.

1. Installation of emergency lighting equipment In the lighting device of the background art, a notch of approximately the same size as the emergency light source unit is provided in the inclined plate in order to arrange the emergency light source unit in the short side direction (see FIG. 18 of Patent Document 1). In this case, there is a risk that the rigidity of the inclined plate and the device body will decrease due to the notch.
The lighting device (X, Y) that solves this problem includes a fixture body (3, 2003), an emergency lighting device (5, 2005), and a fixture (61, 62, 555, 2061, 2062) arranged on the upper surface of the fixture body (3, 2003), and the emergency lighting device (5, 2005) is attached to the part of the fixture body (3, 2003) where the fixture (61, 62, 555, 2061, 2062) is arranged. This allows the emergency lighting device (5, 2005) to be attached simply by providing a through hole for mounting the emergency lighting device (5, 2005) in the fixture body (3, 2003). Therefore, the emergency lighting device (5, 2005) can be attached to the fixture body (3, 2003) without providing a notch or the like that would reduce the mechanical properties of the extension part (inclined plate).

2. Heat Dissipation from Battery Unit In a lighting device equipped with a rechargeable battery, there is a need to improve the heat dissipation properties of the battery.
The lighting device (X) that solves this problem includes a fixture (3), a lamp (5) equipped with a rechargeable battery (54), and a fixture (61, 62, 555) for fixing the lamp (5) to the fixture body (3), the fixture (5) includes a light source unit (51) and a power supply unit (52), the battery (54) is placed on a fixture (61) that fixes the light source unit (51) or the power supply unit (52) to the fixture body (3), and the fixture (61) is made of a metal plate and is fixed to the fixture body (3) in a state of surface contact with the fixture body (3). This allows heat from the battery (54) to be transferred from the fixture (61) to the fixture body (3).

3. Mounting of Units In a lighting device in which a light source unit and a power supply unit are mounted on an extension of a fixture body, there is a need to reduce the number of parts while reducing the weight.
The lighting device (Y) that solves this problem comprises a fixture body (2003), a light source unit (51), a power supply unit (52), a cover (2057), a light source unit attachment fixture (2050), a cover attachment fixture (2058, 2059), a pair of first fixing fixtures (2061) and a second fixing fixture (2062), the first and second fixing fixtures (2061, 2062) being attached to the upper surface of the fixture body (2003) such that the second fixing fixture (2062) is located between the pair of first fixing fixtures (2061), and the pair of power supply units (52) are attached to one of the pair of first fixing fixtures (2062) in the fixture body (2003). The light source unit mounting fixture (2050) is attached to the portion of the fixture body (2003) where the second fixing fixture (2062) and the second fixing fixture (2062) are provided, the light source unit mounting fixture (2050) is attached to the portion of the fixture body (2003) where the second fixing fixture (2062) is provided in a state in which the light source unit (51) is supported below the power supply unit (52), the cover mounting fixtures (2058, 2059) are attached to the portion of the fixture body (2003) where the pair of first fixing fixtures (2061) are provided, and the cover (2057) is removably attached to the cover mounting fixtures (2058, 2059) in a state in which the cover (2057) covers the light source unit (51) and the power supply unit (52) from below.
According to this configuration, the first and second fixing devices (2061, 2062) can reduce the weight of the fixture body (2003), and fewer fixtures are required compared to when the light source unit (51), power supply unit (52), and cover (2057) are individually attached using fixtures.

4. Center of Gravity of the Lighting Device A lighting device that has a normal use lamp and an emergency lamp in the main body and is attached to an installation surface via a suspension bolt is heavier than a lighting device that does not have an emergency lamp, and there is a problem that an excessive load may act on the suspension bolt.
The long lighting device (X, Y) that solves this problem includes a fixture body (3, 2003), a regular lighting device (1), and an emergency lighting device (5, 2005), and the fixture body (3, 2003) has through holes (301a, 2301a) for hanging bolts spaced apart in the longitudinal direction, and the center of gravity of the lighting device (X, Y) when viewed from above is located above the regular lighting device (1) and between the pair of through holes (301, 2301a). This makes it possible to prevent the load from being biased toward one of the hanging bolts.
