The lighting device according to the embodiment of the present disclosure will be described in detail below with reference to the drawings. However, each figure described in the following embodiment is a schematic diagram, and the ratio of the size and thickness of each component does not necessarily reflect the actual dimensional ratio. Note that the configuration described in the following embodiment is merely one example of the present disclosure. The present disclosure is not limited to the following embodiment, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

(1) Overview of the Lighting Fixture According to the Embodiment The lighting fixture A1 according to the embodiment includes a long fixture body 1, one or more light source units 2 detachably attached to the fixture body 1, and functional units arranged adjacent to the light source units 2 along the longitudinal direction of the fixture body 1 (see FIG. 1 ). The lighting fixture A1 according to the embodiment includes a support member 6 (see FIG. 2 ) that supports the functional units.

The functional unit is, for example, an emergency light source unit for providing emergency lighting (also called emergency lighting) in the event of a power outage in the power system. However, the functional unit may also be a sensor unit for detecting the presence of a person, the brightness of the surroundings, and the like, and for flashing or dimming the light source unit 2, or a switch unit having a drawstring switch for switching the flashing of the light source unit 2. Alternatively, the functional unit may be a wireless communication unit for flashing or dimming the light source unit 2 via wireless communication such as Wi-Fi (registered trademark) and Bluetooth (registered trademark), an air purification unit for purifying the air in the lighting space, or a speaker unit for outputting music, etc.

The fixture body 1 has a main body 10 and a pair of side walls 11. The main body 10 is formed in a long plate shape and is attached to a construction member (hanging bolt 90). The pair of side walls 11 face each other in the short direction of the main body 10. The fixture body 1 is configured to accommodate a part of the light source unit 2 and a part of the functional unit in an accommodating recess 12 surrounded by the main body 10 and the pair of side walls 11.

The support member 6 has a fixing portion 7 that is fixed to the device body 1, and an attachment portion 8 to which a functional unit is attached. The support member 6 is accommodated in the accommodation recess 12 so as to form a predetermined space (wiring space S1) between the body 10 and the attachment portion 8.

Here, to supply power to the light source unit 2 and the functional unit, a power cable 91 for indoor wiring is pulled into the storage recess 12 of the fixture body 1. The power cable 91 pulled into the storage recess 12 can be stored in a predetermined space (wiring space S1) formed between the support member 6 and the main body 10 and the mounting part 8. However, the lighting fixture A1 according to the embodiment is not usually installed alone, but rather multiple lighting fixtures A1 are often installed lined up in the longitudinal direction. These multiple lighting fixtures A1 are then connected to each other by the feed wiring of the power cable 91.

The lighting fixture A1 according to the embodiment can accommodate the electric wire (power cable 91) for the transmission wiring inside the fixture body 1. Therefore, the lighting fixture A1 according to the embodiment can improve the workability of the installation work compared to when the electric wire (power cable 91) for the transmission wiring is wired outside the fixture body 1.

(2) Details of the Lighting Fixture According to the Embodiment As shown in Fig. 1 and Fig. 2, the lighting fixture A1 according to the embodiment (hereinafter, abbreviated as lighting fixture A1) includes a fixture body 1, a light source unit 2, an emergency light source unit 3 corresponding to a functional unit, and a support member 6. In the following description, unless otherwise specified, the up-down, front-back, and left-right directions indicated by arrows in Fig. 1 are defined as the up-down, front-back, and left-right directions of the lighting fixture A1.

The lens 40 of the emergency light source block 4 protrudes below the first cover 31 through a hole 311 in the first cover 31 (see Figure 18).

(2-3) Fixture body The fixture body 1 has a main body 10 formed in a long plate shape and attached to a construction member (hanging bolt 90), and a pair of side walls 11 facing each other in the short direction of the main body 10 (see Figs. 1 and 2). The fixture body 1 further has a pair of reflecting plates 13, a pair of end plates 14, and a frame portion 15.

The main body 10 has a base plate 100 formed in a long rectangular shape and a pair of side plates 101 bent downward from both ends (front and rear ends) along the longitudinal direction of the base plate 100 (see Figure 3).

The base plate 100 has two insertion holes 102 and one power hole 103. The two insertion holes 102 are circular holes provided at positions near both ends of the base plate 100 in the longitudinal direction (left-right direction). A hanging bolt 90, which is a construction member, is inserted into each insertion hole 102 (see Figure 2).

The power supply hole 103 is a circular hole provided in the center of the base plate 100 in the longitudinal direction. A power supply cable 91 connected to a regular power supply is pulled into the power supply hole 103 (see FIG. 3). The power supply cable 91 is, for example, a three-core VVF (vinyl insulated vinyl sheath flat) cable.

Two terminal blocks 23 are attached to the underside of the base plate 100 between the power supply hole 103 and the right-side insertion hole 102 (see Figures 2 and 3). A power cable 91 and a relay cable are connected to one of the terminal blocks 23. The power supply device 22 is connected to the power cable 91 via the relay cable and the terminal block 23. The electric wire 44 of the emergency light source block 4 is connected to the other terminal block 23. The power cable 91 for the feed wiring, which will be described later, is also connected to these terminal blocks 23.

A U-shaped support portion 104 is integrally provided at the lower end of each of the pair of side plates 101 (see FIG. 3). In addition, each of the pair of side plates 101 is bent in a stepped shape along the longitudinal direction (left-right direction).

Each of the pair of side walls 11 is formed integrally with the reflector 13. Each reflector 13 is formed as a long rectangular plate with one surface (lower surface) as a reflective surface. Each side wall 11 is a long rectangular plate and is formed integrally with the reflector 13 so as to rise from one edge (upper edge) along the longitudinal direction (left-right direction) of the reflector 13. A protruding wall 110 is provided at the upper end of each side wall 11. The protruding wall 110 is a long rectangular plate and protrudes from the tip edge (upper edge) along the longitudinal direction of the side wall 11 in a direction facing the reflector 13 (see FIG. 3). The tip of the protruding wall 110 is bent downward along the longitudinal direction into a hook shape.

Each of the pair of end plates 14 is formed in a trapezoidal shape (see FIG. 3). Each of the pair of end plates 14 is joined to both ends of the pair of reflectors 13 in the longitudinal direction by a suitable method such as spot welding.

The frame portion 15 is formed in a rectangular frame shape when viewed from the top and bottom. However, it is preferable that the frame portion 15 is formed integrally with the pair of reflectors 13 and the pair of end plates 14.

When the pair of reflectors 13 are joined to the integral end plate 14, the pair of side walls 11 face each other at a predetermined distance in the short direction (front-to-back direction) of the reflector 13 (see Figure 3).

The main body 10 and the pair of side walls 11 are joined as follows. First, the pair of protruding walls 110 are inserted into the inside of the pair of support parts 104 from one end of the main body 10 in the longitudinal direction. Then, the main body 10 is moved parallel to the pair of side walls 11 along the longitudinal direction of the side walls 11. Here, cut-out pieces are provided at both ends of the longitudinal direction of each side wall 11. Meanwhile, notches are provided at the tip of each protruding wall 110. Then, the cut-out pieces of each side wall 11 are crimped into the notches of each protruding wall 110, so that the main body 10 and the pair of side walls 11 are joined via the pair of protruding walls 110.

By joining the main body 10 and the pair of side walls 11, a storage recess 12 surrounded by the main body 10 and the pair of side walls 11 is formed (see Figures 2 to 4 and 6). However, the storage recess 12 is open at both ends (left and right ends) in the longitudinal direction of the device main body 1.

(2-4) Support Member Next, the support member 6 will be described with reference to FIGS.

The support member 6 has a fixing portion 7 that is fixed to the device body 1 and an attachment portion 8 to which the emergency light source unit 3 is attached.

The mounting portion 8 has a mounting plate 80 to which the emergency light source block 4 is attached, a support plate 81 that detachably supports the battery block 5, and an opening 82 disposed between the mounting plate 80 and the support plate 81 (see Figures 7 and 8).

The mounting plate 80 is formed in a rectangular flat plate shape (see Figs. 7 and 8). A rectangular vertical piece 800 is integrally provided on the mounting plate 80 (see Figs. 8 to 11). The vertical piece 800 protrudes downward from the left end of the mounting plate 80 (see Fig. 9). A circular hole 801 penetrates each of the front end and rear end at the center of the left and right direction of the mounting plate 80 (see Figs. 7 and 8). A screw is inserted into each of these two holes 801. Then, the emergency light source block 4 is attached to the underside of the mounting plate 80 by screwing each screw into a screw hole provided in the heat sink 42 (see Fig. 14). The emergency light source block 4 is attached to the mounting plate 80 in a state where it slightly protrudes from the end (right end) of the mounting plate 80 opposite the vertical piece 800 (see Fig. 14).

The support plate 81 is formed in a flat plate shape with an L-shaped outer shape when viewed from the top and bottom (see Figures 7 and 8). A hook portion 810 is provided at the tip (rear end) of the part of the support plate 81 that is narrower in the left and right direction (see Figures 8 to 10 and 12). The hook portion 810 has a main piece 8100, a first hook piece 8101, and a second hook piece 8102. The main piece 8100, the first hook piece 8101, and the second hook piece 8102 are each formed in a rectangular flat plate shape (see Figures 8, 9, and 12). The main piece 8100 protrudes downward from the tip (rear end) of the support plate 81 (see Figures 9 and 10). The first hook piece 8101 protrudes leftward from the tip (lower end) of the main piece 8100 and faces the support plate 81 in the top and bottom directions (see Figures 9 and 10). The second hook piece 8102 protrudes leftward from the front edge of the first hook piece 8101 (see Figures 8 to 10). A female thread 811 is provided at the tip (right end) of the part of the support plate 81 that is wider in the left-right direction (see Figures 7 and 8).

The opening 82 has a rectangular shape when viewed from above and below, and is disposed between the mounting plate 80 and the support plate 81 (see Figs. 7 and 8). The width of the opening 82 along the short side direction (front-to-back direction) of the device body 1 is approximately equal to the distance between the pair of side wall portions 11. However, the shape of the opening 82 is not limited to a rectangle, and may be, for example, a polygon having pentagons or more sides, a circle, an ellipse, etc. The end of the support plate 81 that faces the opening 82 (the left end) is folded back upward (see Figs. 7 and 13).

The battery block 5 is supported on the support plate 81 of the support member 6 in the following procedure. First, the battery block 5 is tilted relative to the support plate 81, and the protrusion 53 on the battery case 50 of the battery block 5 is hooked onto the hook portion 810 on the support plate 81 of the support member 6 (see FIG. 14).

Then, the battery block 5 is rotated around the protrusion 53 hooked on the hook portion 810 (see FIG. 5). Then, the protrusion 55 of the battery block 5 is inserted into the vertical groove 411 provided in the housing 41 of the emergency light source block 4, and the connector portion 54 of the battery block 5 is connected to the receptacle connector 43 (see FIG. 15). In this way, the battery block 5 is supported by the support plate 81 of the support member 6, and the connector portion 54 and the receptacle connector 43 are connected (see FIG. 15). When the battery block 5 is supported by the support plate 81, the opening 82 of the support member 6 is blocked by the battery block 5 (FIG. 17).

The fixing portion 7 has a pair of side plates 70 and a pair of fixing pieces 71 (see Figures 7 to 10). Each of the pair of side plates 70 is formed in a rectangular flat plate shape. One side plate 70 protrudes upward from the front end of the mounting portion 8 (mounting plate 80 and support plate 81) (see Figure 9). The other side plate 70 protrudes upward from the rear end of the mounting portion 8 (mounting plate 80 and support plate 81) (see Figure 10).

Each of the fixing pieces 71 is formed in a rectangular flat plate shape (see FIG. 7). One fixing piece 71 protrudes forward from the upper end of the front side plate 70. The other fixing piece 71 protrudes rearward from the upper end of the rear side plate 70. A circular hole 710 is provided at one longitudinal end (left end) of each of the pair of fixing pieces 71 (see FIG. 7).

Furthermore, each fixed piece 71 has a locking piece 72 at both ends (left and right ends) in the longitudinal direction (see Figures 9 and 10). These four locking pieces 72 are formed in a hook shape and protrude downward from the edge of the fixed piece 71 along the longitudinal direction (left and right direction).

The fixing portion 7 of the support member 6 is fixed to a pair of side walls 11 of the instrument body 1. Specifically, a pair of fixing pieces 71 of the fixing portion 7 are fixed to the protruding wall portions 110 of the pair of side walls 11 of the instrument body 1, one each.

A pair of locking pieces 72 provided on each fixed piece 71 are locked one by one to the edges of a pair of holes 111 provided at the left end of the protruding wall portion 110. In this state, the screw 74 inserted into the hole 710 of the fixed piece 71 is screwed into a screw hole provided in the protruding wall portion 110, thereby fixing the fixed piece 71 to the protruding wall portion 110 (see FIG. 13). Note that the hole 710 through which the screw 74 is inserted is provided at a position where the optical axis L1 of the lens 40 and the screw 74 overlap when viewed from the short side direction (front-back direction) of the fixed piece 71 (see FIG. 15).

Here, when the support member 6 is fixed to the instrument body 1 (the pair of side walls 11), the opening 82 of the support member 6 overlaps in the vertical direction with the insertion hole 102 located at the left end of the main body 10 of the instrument body 1 (see FIG. 15). The opening 82 is formed to a size that allows the operation of tightening the nut 92 onto the hanging bolt 90 inserted into the insertion hole 102 to be performed.

The support member 6 is accommodated in the accommodation recess 12 so as to form a predetermined space (wiring space S1) between the main body 10 and the mounting portion 8 (see FIG. 4). It is preferable that the wiring space S1 is large enough to accommodate at least two power cables 91.

Here, the electric wires 44 for connecting the emergency light source block 4 to the normal power source are arranged in the wiring space S1 through the opening 82 of the support member 6 (see FIG. 6). This makes it possible to prevent the electric wires 44 from being pinched between the battery block 5 and the support plate 81 when the battery block 5 is attached to the support plate 81. The electric wires 44 are supported by a plurality of cable holders 45 attached to the side wall portion 11 and the main body 10 (see FIG. 6).

(3) Installation Procedure for Lighting Fixture According to the Embodiment Next, an installation procedure for lighting fixture A1 will be described.

First, the worker performing the installation work removes the light source unit 2, the battery block 5, and the cover 30 from the lighting fixture A1. Then, the worker inserts the power cable 91, which is wired in advance in the ceiling, into the power hole 103 of the main body 10, and then inserts the fixture main body 1 into the recessed hole X10 provided in the ceiling X1. At this time, the worker inserts the two hanging bolts 90 arranged in the recessed hole X10 into the two insertion holes 102 provided in the main body 10 one by one (see FIG. 2). Then, the worker tightens the nut 92 through the washer 93 on the hanging bolt 90 inserted into the insertion hole 102 (see FIG. 16). At this time, the worker can insert his hand through the opening 82 of the support member 6 of the emergency light source unit 3 and tighten the nut 92. In addition, since the end of the support plate 81, which is the end facing the opening 82 (the left end), is folded upward, the possibility of the worker's hand touching the edge of the support plate 81 and being injured is reduced. Similarly, the emergency light source block 4 is attached to the mounting plate 80 in a state where it slightly protrudes from the end (right end) opposite the vertical piece 800 of the mounting plate 80, reducing the possibility of an operator's hand touching the edge of the mounting plate 80 and being injured.

In this way, the fixture body 1 is fixed to the two hanging bolts 90. The frame portion 15 of the fixture body 1 abuts against the periphery of the embedding hole X10 in the ceiling X1, so that the fixture body 1 covers the embedding hole X10.

The worker then connects the power cable 91 pulled in from the power hole 103 to the terminal block 23. The worker then connects the power cable 91 for the forwarding wiring to the terminal block 23. The worker stores the two power cables 91 in the wiring space S1 of the storage recess 12 of the fixture body 1 (see Figures 3 and 4), and pulls the power cable 91 for the forwarding wiring out of the fixture body 1 from one end of the storage recess 12 in the longitudinal direction, and stores it in the storage recess 12 of the fixture body 1 of another lighting fixture A1.

Next, the worker supports the battery block 5 on the support plate 81 of the support member 6 using the procedure explained in "(2-4) Support member" (see Figures 14 and 15). Then, the worker attaches the cover 30 to the device body 1. The worker inserts the pair of hook springs 312 of the first cover 31 into the gap between the upper end of the left end plate 14 and the left end of the emergency light source block 4. The pair of hook springs 312 are hooked onto protruding pieces that protrude to the right from the upper end of the left end plate 14 of the device body 1 (see Figure 4).

Then, the worker places the fixing portion 322 of the second cover 32 over the female threaded portion 811 of the support plate 81 from below. The worker then attaches the cover 30 to the device body 1 and the support member 6 by screwing the screw 323 inserted into the insertion hole of the fixing portion 322 into the female threaded portion 811 of the support plate 81. Note that multiple protrusions are formed on the upper surface (the surface facing the battery block 5) of the flat portion 320 of the cover 30. These multiple protrusions come into contact with the lower surface of the first case portion 51 of the battery case 50, thereby allowing the cover 30 to suppress rattling of the battery block 5.

Next, the worker attaches the light source unit 2 to the fixture body 1. First, the worker hooks a pair of hooks 211 into the square holes 112 (see FIG. 2) provided in the rear side wall portion 11 of the fixture body 1, temporarily hanging the light source unit 2 on the fixture body 1. With the light source unit 2 temporarily hung on the fixture body 1, the worker connects the power connector connected to the terminal block 23 to the power supply device 22 of the light source unit 2.

Next, the worker hooks the hook spring 212 (see FIG. 3) of the light source unit 2 to the receiving bracket 16 (see FIG. 2) provided on the front side wall 11 of the fixture body 1. Finally, the worker rotates the light source unit 2 so as to lift it up, using the hook bracket 211 as a fulcrum. Then, the hook spring 212 returns to its original state while still hooked to the receiving bracket 16, and the spring force of the hook spring 212 holds the light source unit 2 to the fixture body 1 (see FIGS. 1 and 3).

Lighting fixture A1 is installed on ceiling X1 using the above procedure.

(4) Modifications Several modifications of the lighting device A1 according to the present embodiment will be described below. However, since the basic configuration of each modification described below is common to the basic configuration of the lighting device A1 according to the present embodiment, the common components are denoted by the same reference numerals and will not be illustrated or described.

(4-1) Modification 1
As shown in FIG. 19 , a lighting fixture A1 of the first modification example differs from the embodiment in that it includes two light source units 2 and that an emergency light source unit 3 is disposed between the two light source units 2.

The two light source units 2 each have a length (longitudinal dimension) that is approximately half that of the light source unit 2 in the lighting fixture A1 according to the embodiment. These two light source units 2 are attached to the fixture body 1, close to both ends of the fixture body 1 in the longitudinal direction.

The emergency light source unit 3 is disposed between the two light source units 2, i.e., in the longitudinal center of the device body 1. In this case, the opening 82 of the support member 6 that supports the emergency light source unit 3 faces the power supply hole 103 provided in the center of the body 10.

Therefore, even in the lighting device A1 of variant 1, the power cable 91 can be pulled in from the power hole 103 through the opening 82 of the support member 6.

As mentioned above, the functional unit (emergency light source unit 3) may be located at a position other than the longitudinal end of the device body 1, for example, in the longitudinal center.

(4-2) Modification 2
As shown in FIG. 20 , a lighting fixture A1 of the second modification includes, instead of the emergency light source unit 3, an electrostatic atomization unit 3A having an electrostatic atomization device as a functional unit.

Electrostatic atomizers are configured to generate nano-sized particle ions by applying a high voltage to water in the air. The particle ions generated by electrostatic atomizers contain hydroxyl radicals (OH radicals), which easily react with various substances, and can remove or suppress allergens such as pollen, bacteria, and viruses suspended in the air.

The electrostatic atomization unit 3A has a housing 30A that houses an electrostatic atomization device. The bottom surface of the housing 30A is provided with a number of openings 300A. The fine particle ions generated by the electrostatic atomization device are released into the room through the openings 300A on the bottom surface of the housing 30A.

(4-3) Modification 3
Illumination device A1 of modification 3 is characterized in that fixing portion 7 of support member 6 has only one side plate 70 and one fixing piece 71 (see FIG. 21).

In the lighting fixture A1 of the modified example 3, the fixing part 7 has only one side plate 70 and one fixing piece 71, so the support member 6 can be attached to the fixture body 1 simply by fixing the fixing piece 71 to the protruding wall portion 110 of one side wall portion 11 of the fixture body 1. As a result, the lighting fixture A1 of the modified example 3 can improve the workability of the assembly work.

(4-4) Modification 4
The lighting fixture A1 of the fourth modification is characterized by the structure of the fixing portion 7 of the support member 6. The fixing portion 7 in the fourth modification has a pair of side plates 70 and a pair of fixing pieces 71. The pair of side plates 70 respectively protrude downward from the front end and the rear end of the mounting portion 8 (see FIG. 22 ). The pair of fixing pieces 71 respectively protrude outward from the lower ends of the pair of side plates 70.

The fixing portion 7 of the support member 6 is fixed to a pair of side walls 11 of the instrument body 1. Specifically, a pair of fixing pieces 71 of the fixing portion 7 are fixed by screwing each one to a pair of side walls 11 of the instrument body 1 (see FIG. 22). Each of the pair of fixing pieces 71 is engaged with the lower end of each of the pair of side walls 11.

In the lighting fixture A1 of variant 4, the fixing portion 7 of the support member 6 is positioned below the mounting portion 8, which allows the wiring space S1 to be further expanded (see FIG. 22).

(5) Advantages of the Lighting Fixture According to the Embodiment In the lighting fixture A1, the support member 6 that supports functional units such as the emergency light source unit 3 and the electrostatic atomization unit 3A is accommodated in the accommodation recess 12 of the fixture body 1 so as to form a wiring space S1 between the main body 10 of the fixture body 1 and the mounting portion 8 of the support member 6 (see Figs. 3 and 4). Note that the wiring space S1 is large enough to accommodate at least two power cables 91.

The lighting fixture A1 can accommodate two power cables 91 in the wiring space S1 of the accommodation recess 12: one for supplying power to the power supply device 22 and the functional unit, and the other for sending wiring to another lighting fixture. As a result, the lighting fixture A1 has the advantage of being able to improve the workability of installation work compared to when the wire for sending wiring (power cable 91) is wired outside the fixture body 1.

The storage recess 12 also opens up the wiring space S1 at both longitudinal ends of the fixture body 1 (see Figures 3 and 4). Therefore, when multiple lighting fixtures A1 are installed side by side in the longitudinal direction, a power cable 91 for wiring can be routed from the longitudinal end of the storage recess 12 of one lighting fixture A1 to the storage recess 12 of another lighting fixture A1. As a result, the lighting fixture A1 has the advantage of being able to further improve the workability of installation work.

However, the main body 10 of the fixture main body 1 may bend when the nuts 92 are fastened to the two hanging bolts 90. If the fixing portion 7 of the support member 6 is fixed to the main body 10, the bending of the main body 10 may also affect the support member 6, and the light distribution characteristics of the emergency light source unit 3 supported by the support member 6 may change. In contrast, in the lighting fixture A1, the fixing portion 7 of the support member 6 is fixed to a pair of side wall portions 11. In detail, the fixing pieces 71 provided on the pair of side plates 70 of the fixing portion 7 are fixed to a pair of protruding wall portions 110 that protrude outward from the tip edges along the longitudinal direction of the pair of side wall portions 11 (see FIG. 13). Therefore, the lighting fixture A1 has the advantage of reducing the effect of the bending of the main body 10 on the support member 6 and suppressing changes in the light distribution characteristics of the emergency light source unit 3.

Here, the protruding wall portion 110 to which the fixing piece 71 is fixed protrudes outward from the tip edge along the longitudinal direction of the pair of side wall portions 11, so that when assembling the device body 1, the support member 6 and the main body 10 can be assembled from the same direction relative to the pair of side wall portions 11. Therefore, the lighting device A1 can improve the workability of the assembly work compared to a case in which the support member 6 and the main body 10 are assembled from different directions (e.g., upward and downward) relative to the pair of side wall portions 11.

Furthermore, since the fixing piece 71 is provided on the side plate 70 that protrudes from the respective edges of the mounting plate 80 and the support plate 81 on the side opposite the emergency light source unit 3, the distance between the mounting plate 80 and the support plate 81 can be increased, further reducing the effect of the deflection of the main body 10 on the mounting plate 80 of the support member 6.

The battery case 50 of the battery block 5 of the emergency light source unit 3 has a protrusion 53 that can be hooked onto a hook portion 810 provided on the support plate 81 of the support member 6. That is, in the lighting device A1, the battery block 5 can be temporarily supported on the support member 6 by hooking the protrusion 53 of the battery case 50 onto the hook portion 810. In other words, the lighting device A1 has the advantage that the workability of attaching and removing the cover 30 to and from the device body 1 and the support member 6 can be improved by temporarily supporting the battery block 5 on the support member 6.

Here, in the fixing portion 7 of the support member 6, the holes 710 provided in each fixing piece 71 are provided at positions where the optical axis L1 of the lens 40 and the screw 74 inserted into the hole 710 overlap when viewed from the short side direction (front-to-back direction) of the fixing piece 71 (see FIG. 15). Therefore, in the lighting device A1, even if the support member 6 rattles against the pair of side walls 11, the optical axis L1 of the lens 40 can be prevented from shifting relative to the device body 1.
