(1) Outline The configurations described below are merely examples of the present invention, and the present invention is not limited to the following configurations, and the technical idea relating to the present invention may be other than the following configurations. As long as it does not deviate from the above, various changes can be made according to the design and the like.

The audience seat guide light 1 of the present embodiment is a guide light fixture installed in the audience seats in, for example, a movie theater or a theater. The audience seat guide light 1 is configured to provide effective illuminance for evacuation to the floor surface of the aisle around the audience seats. As shown in FIG. 5, for example, the audience seat guide light 1 of the present embodiment is installed on the side wall 102 of the seat 101 facing the aisle 100 in the movie hall, and is configured to illuminate the floor surface 103. However, the audience seat guide light 1 may be installed not only on the seat 101 but also on a peripheral object (wall or the like) facing the aisle. In short, the "audience seat" here includes not only seats but also peripheral objects.

The audience seat guide light 1 includes a light source unit 2, a support portion 10 (as an example, an inclined plate 32 of a mounting member 3), and a body 4. The light source unit 2 illuminates the floor surface 103 of the passage 100 in the movie theater (construction). The support portion 10 supports the light source unit 2.

The first inspection switch 811 is turned on when the first operating member 821 is pushed backward by the tip of a tool such as a screwdriver, for example. Since the first operation member 821 is not premised on being operated by a human finger, the first operation hole 833 is formed so small that a human finger cannot enter the first operation member 821. The second inspection switch 812 is turned on by, for example, pushing the second operating member 822 rearward by a human finger. Since the second operating member 822 is premised on being operated by a human finger, it is exposed to the outside of the case body 800 through the second operating hole 834, and further, the outside of the cover 42 covering the functional portion 8. Is also exposed.

By the way, in the present embodiment, the control circuit of the power supply device 5 is configured to perform a self-inspection operation (first inspection operation) when the first inspection switch 811 is turned on. The self-inspection operation is to stop the charging circuit, turn on the switch of the switch circuit, operate the emergency lighting circuit for a predetermined time (for example, 30 minutes or 60 minutes), and then operate the charging circuit again. And, it means to turn off the switch of the switch circuit. When performing regular inspection work, an inspection worker who specializes in inspection work usually pushes the first operation member 821 corresponding to the first inspection switch 811 instead of the second inspection switch 812 with the tip of a tool. do.

On the other hand, the control circuit of the power supply device 5 is configured to perform an inspection operation (second inspection operation) different from the self-inspection operation (first inspection operation) when the second inspection switch 812 is turned on. Has been done. The second inspection operation means that the charging circuit is stopped while the second inspection switch 812 is on, and the switch of the switch circuit is turned on to operate the emergency lighting circuit. Then, when the second inspection switch 812 is turned off, the control circuit operates the charging circuit and turns off the switch of the switch circuit. When a person who does not specialize in the inspection work performs the inspection work, he or she usually pushes the head of the second operation member 822 corresponding to the second inspection switch 812 with a finger.

In the present embodiment, the body 4 is further configured to accommodate the power supply device 5, the terminal block 6, the mounting member 3, the emergency power supply 7, and the functional unit 8. The body 4 has a base 41 and a cover 42.

(2.7.2) Base of the body The base 41 is formed in a rectangular box shape with an open front surface, for example, by bending a single metal plate. Specifically, the base 41 has a bottom plate 410, a left side plate 411, a right side plate 412, and an upper side plate 413. Further, the base 41 has a mounting piece 414, a first positioning piece 415, a second positioning piece 416, and a third positioning piece 417.

As shown in FIG. 2, the bottom plate 410 is formed in a substantially rectangular plate shape as a whole. Further, the bottom plate 410 has a pair of elongated holes 410A and 410B and elongated holes 410C (see FIG. 2). These elongated holes 410A to 410C are holes through which a fixture (bolt or the like) used for fixing the body 4 to the side wall portion 102 (FIG. 5) of the seat 101 is inserted. The pair of elongated holes 410A and 410B and the elongated holes 410C penetrate the bottom plate 410 in the thickness direction (front-rear direction). The pair of elongated holes 410A and 410B are arranged adjacent to each other in the left-right direction so that their longitudinal directions are along the vertical direction. The pair of elongated holes 410A and 410B are arranged at positions slightly lower left with respect to the center of the bottom plate 410 in the vertical direction and the horizontal direction. The elongated hole 410C is arranged at a position slightly lower right with respect to the center in the vertical direction and the horizontal direction of the bottom plate 410 so that the longitudinal direction thereof is along the left-right direction.

Further, the bottom plate 410 has a rectangular power supply hole 410D in the region between the pair of elongated holes 410A and 410B and the elongated holes 410C in the left-right direction (see FIG. 2). The power supply hole 410D penetrates the bottom plate 410 in the thickness direction (front-rear direction). The power supply hole 410D is arranged so as to overlap the terminal block 6 when the bottom plate 410 is viewed along the front-rear direction. In other words, the terminal block 6 is arranged in front of the power supply hole 410D so as to close the power supply hole 410D. The power supply line connected to the AC power supply 9 is drawn into the body 4 through the power supply hole 410D and is connected to the terminal block 6 in front of the power supply hole 410D.

The left side plate 411 is formed so as to rise forward from the left end of the bottom plate 410. The left side plate 411 has an elongated rectangular plate shape extending in the vertical direction when viewed along the left-right direction. However, as shown in FIG. 2, the bottom plate 410 has a recess 4101 that is recessed in the direction approaching the LED module 20 side at the lower part of the left end thereof. Therefore, when the base 41 is viewed along the front-rear direction, the lower end of the left side plate 411 is formed up to the left end of the edge portion extending along the left-right direction of the recess 4101 (lower left) of the bottom plate 410.

The mounting piece 414 is formed so as to rise forward from an edge extending along the left-right direction of the recess 4101 of the bottom plate 410. The mounting piece 414 is a portion for mounting the functional portion 8, and is formed in a rectangular plate shape when viewed in the vertical direction. The case body 800 of the functional unit 8 is fixed by screwing or the like near the upper end of the lower surface of the mounting piece 414. That is, the functional unit 8 is arranged at a predetermined distance from the bottom plate 410 when viewed along the vertical direction (see FIG. 1). Therefore, the cable 14 extending from the connector 54 of the power supply device 5 is bent without being subjected to excessive stress, wraps around to the rear side of the functional unit 8, and is connected to the terminal block 803 of the functional unit 8 (see FIG. 2). .. Further, the electric wire 11 extending from the output connector 53 of the power supply device 5 is bent so as to bypass the mounting piece 414 without receiving excessive stress, passes behind the functional unit 8, and the connector 22 at the tip is the light source unit 2. It is connected to the connection block 212 of. In short, a wiring space for wiring the cable 14 and the electric wire 11 is formed on the rear side of the functional unit 8.

Here, the dimensional relationship is defined so that the left side plate 411 does not overlap with the functional portion 8 when the base portion 41 is viewed along the left-right direction. In short, when the functional unit 8 is viewed from the left with the cover 42 removed from the base 41, the functional unit 8 is not covered by the left side plate 411. Therefore, when the functional unit 8 is attached to or removed from the attachment piece 414, the left side plate 411 is less likely to interfere with the work and is excellent in workability.

The first positioning piece 415 is formed so as to rise forward from the lower end of the bottom plate 410. The first positioning piece 415 has an elongated rectangular plate shape extending in the left-right direction when viewed along the up-down direction. The first positioning piece 415 is configured to position the mounting member 3 in the vertical direction. The first positioning piece 415 is in contact with the lower end of the first fixing piece 320 of the mounting member 3.

The dimension relationship of the first positioning piece 415 with respect to the front-rear direction is defined to be sufficiently smaller than the dimension of the left side plate 411 with respect to the front-rear direction so that the first positioning piece 415 does not cover the LED module 20. In the present embodiment, the first positioning piece 415 is configured such that its front end is below the lid 211 of the LED module 20 arranged at an angle (see FIG. 4).

As described above, since the bottom plate 410 has a recess 4101 at the lower part of the left end thereof, when the base 41 is viewed along the front-rear direction, the left end of the first positioning piece 415 is in the vertical direction of the recess 4101. It is formed to the lower end of the edge extending along the line. Further, as shown in FIG. 2, the bottom plate 410 has a recess 4102 recessed in the lower part of the right end thereof in a direction approaching the emergency power supply 7 side. Therefore, when the base portion 41 is viewed along the front-rear direction, the right end of the first positioning piece 415 is formed up to the lower end of the edge portion extending along the vertical direction of the recess 4102 (lower right).

The second positioning piece 416 rises forward from the edge extending along the left-right direction of the recess 4102 of the bottom plate 410, and is further bent inward so that the tip is parallel to the bottom plate 410. As a result, the second positioning piece 416 has a substantially L-shaped plate shape when viewed along the left-right direction. The second positioning piece 416 is configured to position the emergency power supply 7 in the vertical direction. The second positioning piece 416 is in contact with the lower side wall of the emergency power supply 7.

The right side plate 412 is formed so as to rise forward from the right end of the bottom plate 410. The right side plate 412 has an elongated rectangular plate shape extending in the vertical direction when viewed along the left-right direction. However, as shown in FIG. 2, the bottom plate 410 has a recess 4103 that is recessed in the direction approaching the power supply device 5 side at the upper part of the right end thereof. Therefore, when the base 41 is viewed along the front-rear direction, the upper end of the right plate 412 is formed up to the right end of the edge extending along the left-right direction of the recess 4103 (upper right).

Here, the bottom plate 410 has an opposing piece 418 cut up so as to face the right side plate 412 in the region below the elongated hole 410C (see FIG. 2). The facing piece 418 has a rectangular plate shape extending in the vertical direction when viewed along the left-right direction. The facing piece 418 is configured to position the emergency power supply 7 in the left-right direction. In short, the emergency power supply 7 is housed in a space surrounded by the second positioning piece 416, the facing piece 418, the bottom plate 410, and the right side plate 412.

The right side plate 412 is notched in the left half of the upper end thereof when viewed along the left-right direction, and is configured to expose the front half of the right side surface of the emergency power supply 7. There is. As a result, when the emergency power supply 7 is housed in the space surrounded by the second positioning piece 416, the facing piece 418, the bottom plate 410, and the right side plate 412, the right side plate 412 is less likely to interfere with the work, and workability is improved. Is excellent.

The third positioning piece 417 is formed so as to rise forward from an edge extending along the vertical direction of the recess 4103 (upper right). The third positioning piece 417 has an elongated rectangular plate shape extending in the vertical direction. The third positioning piece 417 is configured to position the power supply device 5 in the left-right direction. The third positioning piece 417 is in contact with the right wall of the power supply device 5 (see FIG. 2).

The upper plate 413 is formed so as to rise forward from the upper end of the bottom plate 410. The upper plate 413 has an elongated rectangular plate shape extending in the left-right direction. However, as shown in FIG. 2, the upper plate 413 is not formed at a portion on the left side of the upper end of the bottom plate 410. That is, the base 41 is configured so that the electric wire 12 and the cable 14 connected to the connector 54 of the power supply device 5 are exposed when the base 41 is viewed from above. Therefore, during the wiring work, the upper plate 413 is unlikely to interfere with the work. The upper plate 413 and the third positioning piece 417 stably position the power supply device 5 with respect to the base 41.

As shown in FIG. 1, the left side plate 411 and the right side plate 412 have screw holes 4110 and 4120 into which fixing screws 44 and 44 for fixing the cover 42 to the base 41 are screwed, respectively. The pair of screw holes 4110 and 4120 are arranged so as to face each other. Further, as shown in FIG. 2, when the base 41 is viewed along the front-rear direction, the line segment connecting the pair of screw holes 4110 and 4120 passes slightly below the center position of the bottom plate 410 in the vertical direction. The dimensional relationship is specified in.

(2.7.3) Cover of the body The cover 42 is formed of, for example, a flame-retardant synthetic resin material in a substantially rectangular box shape with an open rear surface. The cover 42 is attached so as to cover the front surface of the base 41. The cover 42 has an opening 420 through which the light emitted from the light source unit 2 passes. Specifically, the cover 42 is composed of a front wall 421, a lower wall 422, a right wall 423, an upper wall 424, and a left wall 425, and an opening 420 is provided in the lower wall 422.

The front wall 421 is formed in a rectangular plate shape. The front wall 421 has a recess 4210 in the lower left region of its front surface that is slightly recessed rearward of the other peripheral regions of the front surface (see FIG. 1). The recess 4210 is formed in a rectangular shape when viewed along the front-rear direction, and is arranged so as to substantially overlap the rectangular front surface of the functional portion 8 housed in the body 4. The front wall 421 has four through holes penetrating in the thickness direction of the front wall 421 at the bottom surface of the recess 4210. Hereinafter, the four through holes are referred to as a first through hole 421A, a second through hole 421B, a third through hole 421C, and a fourth through hole 421D, respectively.

The first through hole 421A is arranged slightly lower left than the center of the bottom surface of the recess 4210 in the vertical direction and the horizontal direction. The first through hole 421A faces the first operating member 821 of the functional unit 8 in the front-rear direction. The second through hole 421B is arranged slightly to the upper right of the center of the bottom surface of the recess 4210. The second through hole 421B exposes the head (front end portion) of the second operating member 822 of the functional portion 8 to the outside of the front wall 421.

The third through hole 421C and the fourth through hole 421D are arranged so as to be aligned with each other along the left-right direction in the lower part of the bottom surface of the recess 4210. The third through hole 421C faces the first display element 801 of the functional unit 8 in the front-rear direction. The fourth through hole 421D faces the second display element 802 of the functional unit 8 in the front-rear direction.

The lower wall 422 is formed so as to rise from the lower end of the front wall 421 toward the bottom plate 410 of the base 41. The lower wall 422 has a substantially trapezoidal plate shape when viewed along the vertical direction. The lower wall 422 has an end surface 4220 facing the floor surface 103 when the audience seat guide light 1 is installed in the seat 101. The end surface 4220 includes at least a first surface 4221 and a second surface 4222 arranged inside the body 4 with respect to the first surface 4221 (see FIG. 1). The first surface 4221 is a flat surface and occupies most of the end surface 4220. The second surface 4222 is a flat surface, which is a surface arranged at the center of the end surface 4220 in the left-right direction. In other words, the first surface 4221 is arranged so as to surround the second surface 4222 in a substantially U shape when viewed along the vertical direction.

The first surface 4221 is slightly inclined with respect to one surface 4100 of the base 41. Specifically, the first surface 4221 is slightly inclined so as to be separated from the floor surface 103 from the rear end toward the front end thereof. The second surface 4222 is also inclined with respect to one surface 4100 of the base 41. Specifically, the second surface 4222 is inclined so as to be separated from the floor surface 103 from the rear end toward the front end thereof. However, the second surface 4222 is inclined at an angle different from that of the first surface 4221. For example, as shown in FIG. 4, when the inclination angle of the first surface 4221 with respect to one surface 4100 is represented by θ1, and the inclination angle of the second surface 4222 with respect to one surface 4100 is represented by θ2, 90> θ1> θ2 [°]. The tilt angle is set so as to meet the condition. In short, in the present embodiment, in order to form the second surface 4222 having a different inclination angle, the central region of the end surface 4220 is slightly recessed toward the inside of the body 4.

In the present embodiment, the opening 420 through which the light emitted from the light source unit 2 passes, that is, the opening 420 arranged to face the LED 200 is arranged in the center of the second surface 4222 having an inclination angle θ2. ing. The opening 420 penetrates the lower wall 422 in the thickness direction thereof. In this case, it is preferable that the second surface 4222 and one surface of the mounting board 201 on which the LED 200 is mounted are parallel to each other. In other words, the inclination angle θ2 of the second surface 4222 is set so as to roughly match the inclination angle of the mounting substrate 201 with respect to one surface 4100 of the base 41, that is, the inclination angle of the inclination plate 32 of the mounting member 3. Is preferable.

By inclining the second surface 4222 at an angle different from that of the first surface 4221 in this way, it is possible to expand the illumination range of the audience seat guide light 1 in the width direction of the aisle 100 (see FIG. 5). In particular, by making the inclination angle θ2 of the second surface 4222 substantially the same as the inclination angle of the inclination plate 32 of the mounting member 3, the illumination range of the audience seat guide light 1 can be further expanded.

The entire end face 4220 may be tilted at an tilt angle θ2, but in this case, the space for accommodating the functional units 8 and the emergency power supply 7 on the left and right sides of the light source unit 2 is narrow in the body 4. turn into. In this respect, it is desirable that the inclination angle θ1 of the first surface 4221 is larger than the inclination angle θ2 of the second surface 4222 as in the present embodiment.

The right wall 423, the upper wall 424, and the left wall 425 are formed so as to rise from the right end, the upper end, and the left end of the front wall 421 toward the bottom plate 410 of the base 41, respectively. The upper wall 424 and the lower wall 422 are arranged so as to face each other in the vertical direction, and have the same shape (substantially trapezoidal plate shape) and the same dimensions. Further, the right wall 423 and the left wall 425 are arranged so as to face each other in the left-right direction, and have the same shape (substantially trapezoidal plate shape) and the same dimensions.

As shown in FIG. 1, each of the right wall 423 and the left wall 425 has a through hole 426 for inserting the fixing screws 44 and 44. In FIG. 1, only the through hole 426 of the right wall 423 is shown. The cover 42 covers the base 41 with its opening rear surface facing the base 41, and then inserts the fixing screws 44 and 44 into the through holes 426 and 426 of the right wall 423 and the left wall 425, and the screw holes 4110 of the base 41. , 4120 is screwed into the base 41.

(2.7.4) Light source unit 2, terminal block 6, power supply device 5, emergency power supply 7, and functional unit housed in the body 4 below the first to third housings of the body. The description will be given focusing on the mutual positional relationship of 8. In the following description, the space for accommodating the light source unit 2 and the terminal block 6 in the body 4 is referred to as "first accommodating portion 431". Further, the space for accommodating the functional unit 8 in the body 4 is called "second accommodating unit 432". Further, the space for accommodating the emergency power supply 7 in the body 4 is called "third accommodating portion 433". The first accommodating portion 431, the second accommodating portion 432, and the third accommodating portion 433 are not accompanied by an entity, and are shown only by dotted lines (imaginary lines) in FIG.

First, since the power supply device 5 has a sufficiently large external dimension as compared with the light source unit 2, the emergency power supply 7, and the like, the power supply device 5 is housed in substantially the upper half of the space in the body 4. A gap is provided on the left side of the power supply device 5 for wiring the electric wire 12 and the cable 14.

On the other hand, the first accommodating portion 431, the second accommodating portion 432, and the third accommodating portion 433 are located in substantially the lower half of the space in the body 4. The first accommodating portion 431 accommodates the light source unit 2 and the terminal block 6 so as to be adjacent to each other along the first direction (vertically upward direction) away from the floor surface 103. The first accommodating portion 431 is located at the center in the left-right direction in the space of substantially the lower half of the body 4. That is, the terminal block 6 is located between the light source unit 2 and the power supply device 5 in the vertical direction.

The second accommodating portion 432 and the third accommodating portion 433 have a third direction orthogonal to the first direction and the second direction when viewed along a second direction (front-back direction) orthogonal to one surface 4100 of the base 41. They are arranged on both sides of the first accommodating portion 431 in the (left-right direction). In the present embodiment, the second accommodating portion 432 is located on the left side of the first accommodating portion 431, and the third accommodating portion 433 is located on the right side of the first accommodating portion 431.

Since the light source unit 2 (and the terminal block 6), the functional unit 8, and the emergency power supply 7 are arranged in a row along the left-right direction in this way, it is possible to contribute to space saving in the body 4. As a result, the audience seat guide light 1 can be downsized. Furthermore, the wiring area can be improved.

In particular, the second accommodating unit 432 for accommodating the functional unit 8 whose external dimensions are smaller than those of the light source unit 2 and the power supply device 5 is located on the left side of the first accommodating unit 431. Therefore, the space through which the electric wires 12 and cables 14 sent from the left side of the power supply device 5 and the electric wires 11 extending from the output connector 53 near the left end in the lower part of the power supply device 5 pass is near the second accommodating portion 432. Can be sufficiently secured in.

(3) Modification examples The following is a list of some modification examples. Hereinafter, the above-described embodiment will be referred to as a “basic example”. The modified examples described below can also be applied in combination with the above-mentioned basic examples as appropriate.

In the basic example, the support portion 10 is composed of a part of the mounting member 3 (inclined plate 32). However, this is not the case, and the support portion 10 may be formed separately from the mounting member 3. That is, a separate inclined plate (support portion 10) screwed and fixed to the base portion 41 is arranged between the light source unit 2 and the mounting member 3, and the light source unit 2 is the separate inclined plate (support portion 10). It may be screwed to 10).

However, if the support portion 10 is composed of a part of the mounting member 3 (inclined plate 32) as in the basic example, the number of parts can be reduced. Further, it is possible to contribute to space saving in the body 4, and it is possible to reduce the size of the passenger seat guide light 1.

Alternatively, the support portion 10 may be formed by cutting up a part of the bottom plate 410 of the base portion 41, for example. In this case, the number of parts can be reduced as in the basic example in which the support portion 10 is composed of a part of the mounting member 3 (inclined plate 32).

In the basic example, the functional unit 8 has two inspection switches (811,812) and two display elements (801,802), but the number of these is not particularly limited. For example, the functional unit 8 may have only the first display element 801.

In the basic example, the inclination angle θ1 of the first surface 4221 and the inclination angle θ2 of the second surface 4222 are set so as to satisfy the condition (90> θ1> θ2 [°]). However, this is only an example, and conversely, a structure that satisfies the condition of 90> θ2> θ1 [°] may be applied. However, as described above, considering that the space for accommodating the functional unit 8 and the emergency power supply 7 is narrowed, the condition of the basic example (90> θ1> θ2 [°]) is better. desirable.

Further, the inclination angle θ1 of the first surface 4221 may be 90 ° or more. However, when the tilt angle θ1 is set to 90 ° or more, the difference between the tilt angle θ1 and the tilt angle θ2 becomes wide, and the light emitted from the light source unit 2 is blocked by the edge portion of the second surface 4222. there is a possibility. Therefore, it is desirable that the inclination angle θ1 of the first surface 4221 is less than 90 °.

The power supply device 5 lights the light source unit 2 by the electric power supplied from the external power source via the terminal block 6. The mounting member 3 mounts the terminal block 6 to the base 41. It is preferable that at least a part of the mounting member 3 is configured to function as the support portion 10. According to the second aspect, the number of parts can be reduced as compared with the case where the mounting member 3 and the support portion 10 are formed separately from each other. Further, it is possible to contribute to space saving in the body 4, and it is possible to reduce the size of the passenger seat guide light 1.

Regarding the audience seat guide light 1 according to the third aspect, in the second aspect, the light source unit 2 and the terminal block 6 are preferably arranged so as to be adjacent to each other along the direction away from the floor surface 103.
