[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, identical or corresponding parts are designated by the same reference numerals, and description thereof will not be repeated. For ease of understanding, the X-axis, Y-axis, and Z-axis of a three-dimensional Cartesian coordinate system are appropriately indicated in the drawings. The X-axis and Y-axis are parallel to the horizontal direction, and the Z-axis is parallel to the vertical direction.

[0019] A lighting fixture 100 according to an embodiment of the present invention will be described with reference to Figures 1 to 3. Figure 1 is a perspective view showing the lighting fixture 100 according to the embodiment of the present invention. Figure 2 is an exploded perspective view showing the lighting fixture 100 according to the embodiment of the present invention. Figure 3 is an exploded perspective view showing the lighting fixture 100 according to the embodiment of the present invention.

[0020] As shown in FIG. 1, lighting fixture 100 is a fixture that emits light, such as a spotlight. Lighting fixture 100 is installed on a wall surface W. Wall surface W corresponds to an example of a "mounting body." Lighting fixture 100 includes plate portion 10, lighting unit 20, and housing 40.

[0021] The plate unit 10 is installed on a wall surface W. The wall surface W is a surface of a wall material that divides a room and faces the interior of the room. The wall surface W includes not only the side wall surfaces but also the ceiling surface and floor surface. In this embodiment, the wall surface W is a surface that is approximately parallel to the X-axis and Z-axis. The plate unit 10 surrounds the lighting unit 20 installed on the wall surface W.

[0022] 2, the plate unit 10 includes a first plate 10A and a second plate 10B. The first plate 10A and the second plate 10B overlap in the Y-axis direction. The first plate 10A and the second plate 10B are installed on a wall surface W while overlapping in the Y-axis direction.

[0023] The first plate 10A covers the second plate 10B. In this embodiment, the first plate 10A is located closer to the second plate 10B in one direction Y1 in the Y-axis direction. The first plate 10A has a first opening H1. The first opening H1 penetrates the main body of the first plate 10A in the Y-axis direction. The first plate 10A also has a hook-shaped portion (not shown) extending toward the other direction Y2 in the Y-axis direction.

[0024] The second plate 10B covers a portion of the lighting unit 20. The second plate 10B is fixed to the lighting unit 20 installed on the wall W with screws B1 and B2. The second plate 10B is located on one side Y1 in the Y-axis direction relative to the wall W. The second plate 10B is located on the other side Y2 in the Y-axis direction relative to the first plate 10A.

[0025] The second plate 10B has a second opening H2. The second opening H2 penetrates the main body of the second plate 10B in the Y-axis direction. The second opening H2 has a larger area than the first opening H1. The second plate 10B has a recess corresponding to the hook-shaped portion of the first plate 10A. The hook-shaped portion of the first plate 10A fits into the recess of the second plate 10B. This allows the first plate 10A to be attached to the second plate 10B. In other words, the first plate 10A and the second plate 10B have a snap-fit mechanism.

[0026] The lighting unit 20 is fixed to the housing 40. The lighting unit 20 emits light. As shown in FIG. 1 , a portion of the lighting unit 20 is embedded in the wall surface W. A portion of the lighting unit 20 is inserted into the third opening H3. The lighting unit 20 is installed so that a portion of the lighting unit 20 is embedded in the wall surface W and another portion is exposed to the room.

[0027] Specifically, as shown in FIG. 3, a third opening H3 is formed in the wall surface W. The third opening H3 connects the inside of the wall to the outside of the wall in the Y-axis direction. The length of the third opening H3 in the Z-axis direction is L11. The third opening H3 is larger than the first opening H1 shown in FIG. 1. That is, the length L11 of the third opening H3 along the Z-axis direction is longer than the length of the first opening H1 along the Z-axis direction. Furthermore, the length of the third opening H3 along the X-axis direction is longer than the length of the first opening H1 along the X-axis direction. Therefore, when the plate portion 10 is attached to the lighting unit 20, the edge E30 of the third opening H3 is covered by the first plate 10A. Therefore, the edge E30 of the third opening H3 is not visible to the worker.

[0028] As shown in Fig. 1, the housing 40 accommodates a portion of the lighting unit 20. The housing 40 is fixed to a wall surface W. The lighting unit 20 is fixed to the housing 40 fixed to the wall surface W. As shown in Fig. 3, the housing 40 includes an accommodating portion 41 and an attachment portion 42.

[0029] The storage section 41 stores a part of the lighting unit 20. The storage section 41 is a rectangular parallelepiped box with an opening. The storage section 41 has an opening on one side Y1 in the Y-axis direction and a bottom plate on the other side Y2 in the Y-axis direction.

[0030] The mounting portion 42 covers a portion of the opening of the storage portion 41. The lighting unit 20 is attached to the mounting portion 42. The mounting portion 42 includes a first flat plate portion 421, a side wall portion 422, a second flat plate portion 423, a first mounting piece 425, and a second mounting piece 426. The first mounting piece 425 and the second mounting piece 426 correspond to an example of a "mounting body."

[0031] The first flat plate portion 421 covers a portion of the opening of the storage portion 41. The side wall portion 422 extends from the first flat plate portion 421 to the Y1 side in the Y-axis direction. The side wall portion 422 is located more inward than the outer edge of the first flat plate portion 421. The second flat plate portion 423 extends more inward than the outer edge of the side wall portion 422.

[0032] The second flat plate portion 423 has a fourth opening H4. The fourth opening H4 is an example of an "opening." The fourth opening H4 connects the inside and outside of the storage portion 41. The fourth opening H4 is aligned with the first opening H1, the second opening H2, and the third opening H3 in the Y-axis direction. In other words, the fourth opening H4 connects with the first opening H1, the second opening H2, and the third opening H3.

[0033] In this embodiment, the fourth opening H4 is smaller than the third opening H3 shown in Fig. 3. Specifically, the length L12 of the fourth opening H4 along the Z-axis direction is shorter than the length L11 of the third opening H3 along the Z-axis direction. Furthermore, the length of the fourth opening H4 along the X-axis direction is shorter than the length of the third opening H3 along the X-axis direction. Therefore, when the housing 40 is attached to the wall surface W, the edge E40 of the fourth opening H4 is visible from the third opening H3.

[0034] In this embodiment, the length L13 of the second flat plate portion 423 in the Z-axis direction is longer than the length L11 of the third opening H3 in the Z-axis direction shown in Fig. 3. The length of the second flat plate portion 423 in the X-axis direction is longer than the length of the third opening H3 in the X-axis direction. Therefore, when the housing 40 is attached to the wall surface W, the outer edge of the second flat plate portion 423 cannot be seen from the third opening H3.

[0035] The first mounting piece 425 extends toward the inside of the fourth opening H4. Specifically, the first mounting piece 425 extends from an end of the second flat plate portion 423 on one side Z1 in the Z axis direction toward the other side Z2 in the Z axis direction. The first mounting piece 425 has a mounting hole H33. The mounting hole H33 is a through hole. The mounting hole H33 may have a thread formed therein.

[0036] The second mounting piece 426 extends toward the inside of the fourth opening H4. Specifically, the second mounting piece 426 extends from an end of the second flat plate portion 423 on the other side in the Z-axis direction, Z2, toward one side in the Z-axis direction, Z1. The second mounting piece 426 has a mounting hole H32. The mounting hole H32 is a through-hole. The mounting hole H32 may have a thread formed therein. The second mounting piece 426 is disposed spaced apart from the first mounting piece 425.

[0037] In this embodiment, when lighting fixture 100 is attached to wall surface W, as shown in FIG. 3, housing 40 is attached to wall surface W so that third opening H3 in wall surface W and fourth opening H4 in housing 40 are aligned in the Y-axis direction. Next, as shown in FIG. 2, lighting unit 20 is inserted into third opening H3 in wall surface W. Then, lighting unit 20 is fixed to housing 40 with screws B3 and B4. Specifically, screw B3 is fastened to mounting hole H33 of first mounting piece 425 through lighting unit 20. Screw B4 is fastened to mounting hole H32 of second mounting piece 426 through lighting unit 20.

[0038] Next, second plate 10B is attached to lighting unit 20. Specifically, second plate 10B is fixed to lighting unit 20 with screws B1 and B2. Then, first plate 10A is attached to second plate 10B. Through these steps, lighting fixture 100 is attached to wall surface W.

[0039] Next, the lighting unit 20 will be described in detail with reference to FIGS. 1 to 8. FIG. 4 is a perspective view showing the lighting unit 20 according to an embodiment of the present invention. The lighting unit 20 corresponds to an example of an "electrical equipment unit." FIG. 5 is an exploded perspective view of the lighting unit 20 according to an embodiment of the present invention. FIG. 6 is a plan view showing the fixed body 21 of the lighting unit 20 according to an embodiment of the present invention. FIG. 6 shows the fixed body 21 as viewed from one direction Y1 in the Y-axis direction. FIG. 7 is a rear view showing the fixed body 21 of the lighting unit 20 according to an embodiment of the present invention. FIG. 7 shows the fixed body 21 as viewed from the other direction Y2 in the Y-axis direction. As shown in FIGS. 4 and 5, the lighting unit 20 includes the fixed body 21, a cover 22, a lighting device 23, and a housing 24. FIG. 8 is a cross-sectional view taken along line VIII-VIII of the lighting fixture 100 shown in FIG. 1.

[0040] The lighting device 23 emits light. The lighting device 23 is an example of an "electrical device."

[0041] The fixed body 21 is a member for fixing the lighting unit 20 to the wall surface W. The fixed body 21 is made of, for example, metal in consideration of durability. The fixed body 21 is a substantially plate-shaped member. The storage section 24 is attached to the fixed body 21. As shown in FIG. 2, the fixed body 21 is fixed to a housing 40 that is attached to the wall surface W. Specifically, the fixed body 21 is fixed to the mounting section 42 by screws B3 and B4. The fixed body 21 includes a placement section 211 and a pair of side wall sections 212. The screws B3 and B4 fix the fixed body 21 to the housing 40.

[0042] The lighting device 23 is disposed in the arrangement portion 211. The arrangement portion 211 has a first end E1, a second end E2, and a plurality of through holes. The first end E1 is an end of the arrangement portion 211 on one direction D11 side in the first direction D1. The second end E2 is an end of the arrangement portion 211 on the other direction D12 side in the first direction D1. The plurality of through holes include a first through hole H21 and a second through hole H22.

[0043] The first direction D1 is a direction along the direction from the first through hole H21 to the second through hole H22. In this embodiment, the first direction D1 indicates a direction along the Z-axis direction. One direction D11 side of the first direction D1 is a direction from the second through hole H22 to the first through hole H21. One direction D11 of the first direction D1 is the same direction as the direction toward one direction Z1 in the Z-axis direction. The other direction D12 side of the first direction D1 is the direction from the first through hole H21 to the second through hole H22. The other direction D12 of the first direction D1 is the same direction as the direction toward the other direction Z2 in the Z-axis direction.

[0044] As shown in FIG. 5, the first through hole H21 penetrates in the Y-axis direction. A screw B3 is inserted into the first through hole H21. The first through hole H21 is located at the first end E1. The first through hole H21 overlaps with the first mounting piece 425 shown in FIG. 3. Specifically, the first through hole H21 overlaps with the first mounting piece 425 in the Y-axis direction. The first through hole H21 is also aligned with the mounting hole H33 of the first mounting piece 425 in the Y-axis direction. The first through hole H21 communicates with the mounting hole H33. The first through hole H21 is formed in an elongated hole shape and is larger than the mounting hole H33. By providing the first through hole H21 in this manner, it becomes easier to communicate with the mounting hole H33 and it is possible to fine-tune the position of the fixed body 21 relative to the wall surface W.

[0045] The second through hole H22 penetrates in the Y-axis direction. The second through hole H22 is located at the second end E2. The second through hole H22 overlaps with the second mounting piece 426 shown in FIG. 3. Specifically, the second through hole H22 overlaps with the second mounting piece 426 in the Y-axis direction. The second through hole H22 is also aligned with the mounting hole H32 of the second mounting piece 426 in the Y-axis direction. The second through hole H22 communicates with the mounting hole H32. The second through hole H22 is formed in an elongated hole shape and is larger than the mounting hole H32. Providing the second through hole H22 in this manner makes it easier to communicate with the mounting hole H32 and allows for fine adjustment of the position of the fixed body 21 relative to the wall surface W.

[0046] The arrangement portion 211 extends in a first direction D1. The arrangement portion 211 extends in a second direction D2 that intersects with the first direction D1. The second direction D2 indicates a direction along the direction from one side wall portion 212A to the other side wall portion 212B. One direction D21 of the second direction D2 indicates a direction from the other side wall portion 212B to one side wall portion 212A. The other direction D22 of the second direction D2 indicates a direction from one side wall portion 212A to the other side wall portion 212B.

[0047] In this embodiment, the first through hole H21 and the second through hole H22 have an elongated hole shape. Specifically, the edges of the first through hole H21 and the second through hole H22 have linear edges and arc edges.

[0048] 6, the first through hole H21 has a linear edge E21A, a linear edge E21B, an arc-shaped edge E21C, and an arc-shaped edge E21D. The linear edge E21A is located on the other direction D12 side of the first direction D1. The linear edge E21B is located on the one direction D11 side of the first direction D1. The arc-shaped edge E21C is located on the one direction D21 side of the second direction D2. The arc-shaped edge E21D is located on the other direction D22 side of the second direction D2.

[0049] The second through hole H22 has a linear edge E22A, a linear edge E22B, an arc-shaped edge E22C, and an arc-shaped edge E22D. The linear edge E22A is located on the other direction D12 side of the first direction D1. The linear edge E22B is located on the one direction D11 side of the first direction D1. The arc-shaped edge E22C is located on the one direction D21 side of the second direction D2. The arc-shaped edge E22D is located on the other direction D22 side of the second direction D2.

[0050] 5 to 7, the pair of side walls 212 protrude from the ends of the placement portion 211 in the second direction D2. The pair of side walls 212 can improve the rigidity of the fixed body 21. In addition, the pair of side walls 212 makes it easier to grip the fixed body 21.

[0051] As shown in FIG. 4 , the pair of side walls 212 protrude in a direction D32 opposite the third direction D3. The third direction D3 is a direction extending from the cover 22 toward the fixed body 21. The other direction D32 of the third direction D3 is the direction extending from the cover 22 toward the fixed body 21. The one direction D31 of the third direction D3 is the direction extending from the fixed body 21 toward the cover 22. That is, the pair of side walls 212 extend toward the fourth opening H4. Therefore, the pair of side walls 212 do not protrude toward the plate 10. Therefore, the pair of side walls 212 do not come into contact with the plate 10. This reduces the gap between the plate 10 and the wall surface W when the plate 10 is attached to the fixed body 21.

[0052] The pair of side walls 212 include a first side wall 212A and a second side wall 212B. The first side wall 212A protrudes from the arrangement portion 211 toward the third opening H3. Specifically, the first side wall 212A protrudes from an end of the arrangement portion 211 on one direction D21 side in the second direction D2 toward the other direction D32 side in the third direction D3. The first side wall 212A extends in the first direction D1.

[0053] The first side wall portion 212A has an end E3 and an end E4. The end E3 of the first side wall portion 212A on the one direction D11 side in the first direction D1 is located in an area A1. The area A1 indicates an area from an edge E21A of the first through hole H21 on the other direction D12 side in the first direction D1 to an edge E11 of the first end E1 on the one direction D11 side in the first direction D1. In other words, the end E3 of the first side wall portion 212A is located closer to the first end E1 than the edge E21A of the first through hole H21. Therefore, the first through hole H21 and the first mounting piece 425 can be aligned with each other by aligning the end E3 of the first side wall portion 212A with the edge E30 of the third opening H3 in the wall surface W. That is, when the fixed body 21 is attached to the housing 40, the fixed body 21 follows the edge E30, which prevents the fixed body 21 from moving excessively, facilitating the positioning of the fixed body 21 and the housing 40. As a result, the work of attaching the lighting unit 20 to the wall surface W becomes easier.

[0054] For example, as shown in FIG. 8, the fixed body 21 can be moved in one direction D21 in the second direction D2 and in the other direction D22 in the second direction D2 by aligning the end E3 of the first side wall portion 212A with the edge E30 of the third opening H3 in the wall surface W on the one direction D11 side in the first direction D1. This allows the first mounting piece 425 to be located through the first through-hole H21. Furthermore, by bringing the end E3 into contact with the edge E30 of the third opening H3, movement of the fixed body 21 in the one direction D11 side in the first direction D1 can be prevented. As a result, the work of attaching the fixed body 21 to the housing 40 is facilitated.

[0055] Furthermore, the end E3 of the first side wall portion 212A may be located in region A2. Region A2 refers to the region from an edge E21A of the first through hole H21 on the other side D12 in the first direction D1 to an edge E21B of the first through hole H21 on the one side D11 in the first direction D1. Therefore, when the end E3 is brought into contact with the edge E30 of the third opening H3, the first through hole H21 and the first mounting piece 425 can be easily aligned. As a result, the first through hole H21 and the mounting hole H33 can be aligned, and the housing 40 and the fixed body 21 can be easily fixed with the screw B3.

[0056] More specifically, the end E3 of the first side wall portion 212A may be located closer to the edge E21A than the center of the first through hole H21. Alternatively, the position of the end E3 may be approximately coincident with the edge E21A. Alternatively, the position of the end E3 may be coincident with the edge E21A. The position of the end E3 of the first side wall portion 212A may be the same as the edge E21A or closer to the first end E1 than the edge E21A. In other words, the position of the center of the first through hole H21 in the first direction D1 may be the same as the end E3 in the first direction D1. Alternatively, the position of the center of the first through hole H21 in the first direction D1 may be closer to the other direction D12 of the first direction D1 than the end E3 in the first direction D1. Therefore, even if the first mounting piece 425 extends from the edge E40 of the fourth opening H4 toward the inside of the fourth opening H4, the first through hole H21 and the first mounting piece 425 can be overlapped in the Y-axis direction.

[0057] Furthermore, the first side wall portion 212A faces an edge E30 on the one direction D21 side in the second direction D2 of the third opening H3 (the one direction X1 side of the X axis in FIG. 3). That is, when the first side wall portion 212A comes into contact with the edge E30 on the one direction D21 side in the second direction D2 of the third opening H3, movement of the fixed body 21 in the one direction D21 side in the second direction D2 is restricted. As a result, when the fixed body 21 is attached, excessive movement of the fixed body 21 in the one direction D21 side in the second direction D2 can be suppressed.

[0058] The end E4 of the first side wall portion 212A on the other direction D12 side of the first direction D1 is located in the region A1. The region A1 indicates the region from the edge E22B of the second through hole H22 on the one direction D11 side in the first direction D1 to the edge E21 of the second end E2 on the other direction D12 side in the first direction D1. In other words, the position of the end E4 of the first side wall portion 212A is located closer to the second end E2 than the edge E22B of the first through hole H21. Therefore, the end E4 and end E3 of the first side wall portion 212A can be aligned along the edge E30 of the third opening H3 of the wall surface W to align the second through hole H22 with the second mounting piece 426 and the first through hole H21 with the first mounting piece 425. This further facilitates the work of attaching the fixed body 21 to the housing 40. As a result, the work of attaching the lighting unit 20 to the wall surface W becomes even easier.

[0059] For example, as shown in FIG. 8 , the fixed body 21 can be moved in one direction D21 in the second direction D2 (one direction X1 on the X axis) and the other direction D22 in the second direction D2 (the other direction X2 on the X axis) by aligning the end E4 of the first side wall portion 212A with the edge E30 on the other direction D12 side of the third opening H3 in the wall surface W. Therefore, the second mounting piece 426 can be located through the second through-hole H22. Furthermore, by bringing the end E4 into contact with the edge of the third opening H3, the fixed body 21 can be prevented from moving in the other direction D12 on the first direction D1. In other words, the fixed body 21 can be prevented from falling when it is fixed to the housing 40. This further simplifies the process of attaching the fixed body 21 to the housing 40.

[0060] Furthermore, the end E4 of the first side wall portion 212A may be located in a region A2 extending from an edge E22B of the second through hole H22 on one side D11 in the first direction D1 to an edge E22A of the second through hole H22 on the other side D12 in the first direction D1. Therefore, when the end E4 contacts the edge E30 of the third opening H3, the second through hole H22 and the second mounting piece 426 are aligned. As a result, the second through hole H22 and the mounting hole H32 can be aligned, and the housing 40 and the fixed body 21 can be easily fixed with the screw B4. Furthermore, since the end E3 and the end E4 are aligned along the edge E30 of the third opening H3, the first through hole H21 and the first mounting piece 425 are aligned, and the second through hole H22 and the second mounting piece 426 are also aligned. As a result, the alignment of the fixed body 21 and the housing 40 becomes even easier.

[0061] More specifically, the end E4 of the first side wall portion 212A may be located closer to the edge E22B than the center of the second through hole H22. The position of the end E4 may be approximately coincident with the edge E22B. The position of the end E4 may also coincide with the edge E22B. The position of the end E4 of the first side wall portion 212A may be the same as the edge E22B or closer to the second end E2 than the edge E22B. In other words, the position of the center of the second through hole H22 in the first direction D1 may be the same as the end E4 in the first direction D1. The position of the center of the first through hole H21 in the first direction D1 may be closer to the one direction D11 in the first direction D1 than the end E4 in the first direction D1. Therefore, even if the second mounting piece 426 extends from the edge E40 of the fourth opening H4 toward the inside of the fourth opening H4, the second through hole H22 and the second mounting piece 426 can be overlapped in the Y-axis direction.

[0062] The second side wall 212B protrudes from an end of the arrangement portion 211 on the other side D22 side in the second direction D2 toward the other side D32 side in the third direction D3. The second side wall 212B extends in the first direction D1. The second side wall 212B faces the first side wall 212A. This improves the rigidity of the arrangement portion 211 of the fixed body 21. For example, even if a worker attaches the fixed body 21 to the housing 40 by excessively pressing the fixed body 21 while installing the screws B3 and B4, the improved rigidity of the arrangement portion 211 can prevent deformation of the arrangement portion 211. As a result, it is possible to prevent a gap from being formed between the plate member 10 and the wall surface W due to deformation of the arrangement portion 211.

[0063] The second side wall portion 212B faces an edge E30 of the third opening H3 on the other direction D22 side in the second direction D2 (the other direction X2 side of the X axis in FIG. 3). In other words, when the second side wall portion 212B comes into contact with the edge of the third opening H3 on the other direction D22 side in the second direction D2, movement of the fixed body 21 in the other direction D22 side in the second direction D2 is restricted. As a result, when the fixed body 21 is attached, excessive movement of the fixed body 21 in the other direction D22 side in the second direction D2 can be suppressed.

[0064] The second side wall portion 212B has an end E5 and an end E6. The description of the end E5 and the end E6 is the same as the description of the end E3 and the end E4 of the first side wall portion 212A, and therefore will not be repeated.

[0065] Furthermore, in this embodiment, the fixed body 21 can be moved in the second direction D2 (the X-axis direction in FIG. 3 ) by aligning the end E5 of the second side wall portion 212B and the end E3 of the first side wall portion 212A along the edge of the third opening H3 of the wall surface W on the one direction D11 side in the first direction D1 (the one direction Z1 side of the Z axis in FIG. 3 ). As a result, the end E3 and end E5 of the fixed body 21 come into contact with the edge of the third opening H3, stabilizing the posture of the fixed body 21. This also stabilizes the posture of the first through hole H21. As a result, the first mounting piece 425 can be easily viewed through the first through hole H21.

[0066] Furthermore, in this embodiment, the fixed body 21 can be moved in the second direction D2 by aligning the end E6 of the second side wall portion 212B and the end E4 of the first side wall portion 212A along the edge of the third opening H3 of the wall surface W on the other side D12 of the first direction D1 (the other side Z2 of the Z axis in FIG. 3). Therefore, the end E4 and end E6 of the fixed body 21 contact the edge of the third opening H3, stabilizing the posture of the fixed body 21. Therefore, the posture of the first through hole H21 is also stabilized. As a result, the first mounting piece 425 can be easily viewed through the first through hole H21.

[0067] Continuing with reference to FIGS. 1 to 8, the fixed body 21 will be described in detail. The placement section 211 of the fixed body 21 further has a first surface SF1 and a second surface SF2. As shown in FIG. 6, the first surface SF1 is a surface on one direction D31 side of the third direction D3. The first surface SF1 faces the cover section 22. As shown in FIG. 7, the second surface SF2 is a surface on the other direction D32 side of the third direction D3. The second surface SF2 faces the storage section 24.

[0068] 5, the placement portion 211 further has a mounting hole H23, a mounting hole H24, a protrusion P25, a protrusion P26, a mark M27, a mounting hole H28, a through-hole H29, a protrusion 211A, and a flat plate portion 211B. The flat plate portion 211B corresponds to an example of an "attachment portion."

[0069] The mounting hole H23 penetrates from the first surface SF1 to the second surface SF2 of the placement portion 211. The mounting hole H23 has a circular shape. The mounting hole H23 is located between the first through hole H21 and the first end E1. The mounting hole H23 may have a threaded groove. As shown in FIG. 2, a screw B1 is inserted into the mounting hole H23.

[0070] The mounting hole H24 penetrates from the first surface SF1 to the second surface SF2 of the placement portion 211. The mounting hole H24 has a circular shape. The mounting hole H24 is located between the second through hole H22 and the second end E2. A screw groove may be formed in the mounting hole H24. As shown in FIG. 2, a screw B2 is inserted into the mounting hole H24.

[0071] The mark portion M27 indicates the mounting direction. The mark portion M27 is an example of a "first mark portion." The mark portion M27 protrudes from the first surface SF1 toward one direction D31 in the third direction D3. The mark portion M27 has a polygonal shape. The mark portion M27 is, for example, triangular. The mark portion M27 may also be arrow-shaped. The mark portion M27 is located between the through hole H29 and the second side wall portion 212B. The mark portion M27 is located closer to the second side wall portion 212B than the first through hole H21. The mark portion M27 is also located closer to the first end portion E1 than the protrusion 211A.

[0072] The mark portion M27 protrudes toward one direction D31 in the third direction D3, but is not limited to this. For example, the mark portion M27 may be a sticker attached to the placement portion 211. The mark portion M27 may have any shape as long as it allows the worker to recognize the installation direction.

[0073] The protrusion P25 protrudes from the first surface SF1 toward one direction D31 in the third direction D3. The protrusion P25 indicates the mounting direction. The protrusion P25 is an example of a "first marking portion." The protrusion P25 is located closer to the first end E1 than the first through hole H21. The protrusion P25 is located closer to the first side wall portion 212A than the mounting hole H23.

[0074] The protrusion P26 protrudes from the first surface SF1 toward one direction D31 in the third direction D3. The protrusion P26 indicates the mounting direction. The protrusion P26 is an example of a "first marking portion." The protrusion P26 is located closer to the second end E2 than the second through hole H22. The protrusion P26 is located closer to the second side wall portion 212B than the second through hole H22.

[0075] The mounting hole H28 penetrates from the first surface SF1 to the second surface SF2 of the placement portion 211. The mounting hole H28 has a circular shape. The mounting hole H28 is located between the first through hole H21 and the second through hole H22. The mounting hole H28 is located closer to the second through hole H22 than the protrusion 211A. The mounting hole H28 is located closer to the second side wall portion 212B than the second through hole H22. A screw groove may be formed in the mounting hole H28.

[0076] The through hole H29 penetrates from the first surface SF1 to the second surface SF2 of the arrangement portion 211. The through hole H29 has a rectangular shape. Specifically, the through hole H29 has a rectangular shape. The through hole H29 is located between the mark portion 27 and the first side wall portion 212A. The through hole H29 is located closer to the first side wall portion 212A than the first through hole H21. Furthermore, the through hole H29 is located closer to the first end portion E1 than the protrusion 211A.

[0077] The protruding portion 211A protrudes from the arrangement portion 211 toward one direction D31 in the third direction D3. The protruding portion 211A includes a base portion 211C and an apex portion 211D. The apex portion 211D is located closer to the one direction D31 in the third direction D3 than the base portion 211C. The apex portion 211D is connected to the flat plate portion 211B. As shown in FIG. 6, the base portion 211C is located more outward than the apex portion 211D in a plan view. The protruding portion 211A is inclined from the apex portion 2111D toward the base portion 211C.

[0078] The flat plate portion 211B is supported by the protruding portion 211A. Specifically, the flat plate portion 211B is connected to the top portion 211D. Therefore, the flat plate portion 211B protrudes further in one direction D31 in the third direction D3 than the first surface SF1 of the placement portion 211. In addition, a shaft 23j of the lighting device 23, which will be described later, is attached to the flat plate portion 211B. The shaft 23j corresponds to an example of a "first component." The flat plate portion 211B is exposed from a fifth opening H5, which will be described later, of the cover portion 22. In this embodiment, the shaft 23j is attached to the flat plate portion 211B exposed from the fifth opening H5 of the cover portion 22. The flat plate portion 211B has a ring shape. That is, the flat plate portion 211B has a sixth opening H6. The sixth opening H6 is a through-hole that penetrates in the Y-axis direction.

[0079] 7, the fixed body 21 further has a plurality of reinforcing portions. By providing the fixed body 21 with a plurality of reinforcing portions, the rigidity of the fixed body 21 can be further increased. The reinforcing portions reinforce, for example, the arrangement portion 211 and the first side wall portion 212A, and the arrangement portion 211 and the second side wall portion 212B. The reinforcing portions are arranged on the second surface SF2 of the arrangement portion 211.

[0080] The multiple reinforcing portions each protrude toward the other direction D32 of the third direction D3 (the other direction Y2 in the Y-axis direction) and toward the second direction D2. The multiple reinforcing portions include reinforcing portions R1, R2, R3, and R4. Reinforcing portions R1 and R2 extend from the arrangement portion 211 to the first side wall portion 212A. Reinforcing portions R1 and R2 correspond to an example of a "first reinforcing portion." Reinforcing portions R1 and R2 reinforce the arrangement portion 211 and the first side wall portion 212A. Reinforcing portion R1 is arranged from the arrangement portion 211 to the first side wall portion 212A. Reinforcing portion R1 is arranged on the end E3 side of the first side wall portion 212A. Reinforcing portion R2 is arranged from the arrangement portion 211 to the first side wall portion 212A. The reinforcing portion R2 is disposed on the end E4 side of the first side wall portion 212A.

[0081] Reinforcement portion R3 and reinforcement portion R4 extend from the arrangement portion 211 to the second side wall portion 212B. Reinforcement portion R3 and reinforcement portion R4 correspond to an example of a "second reinforcement portion." Reinforcement portion R3 and reinforcement portion R4 reinforce the arrangement portion 211 and the second side wall portion 212B. Reinforcement portion R3 is arranged from the arrangement portion 211 to the second side wall portion 212B. Reinforcement portion R3 is arranged on the end E5 side of the second side wall portion 212B. Reinforcement portion R4 is arranged from the arrangement portion 211 to the second side wall portion 212B. Reinforcement portion R4 is arranged on the end E6 side of the second side wall portion 212B.

[0082] Reinforcement portions R1 to R4 can suppress deformation of the arrangement portion 211. For example, when an operator attaches the fixed body 21 to the housing 40, deformation of the fixed body 21 may cause a gap to form between the plate portion 10 attached to the fixed body 21 and the wall surface W. Furthermore, depending on the degree of deformation of the fixed body 21, it may be impossible to attach the plate portion 10. In this way, suppressing deformation of the arrangement portion 211 can suppress the generation of a gap between the plate portion 10 and the wall surface W. Furthermore, suppressing deformation of the arrangement portion 211 can suppress improper attachment of the plate portion 10 to the fixed body 21.

[0083] Next, the cover portion 22 will be described with reference to Figures 2, 4, 5, 8, and 9. Figure 9 is a view of the lighting unit 20 shown in Figure 4 as seen from one direction D31 of the third direction D3.

[0084] 2 and 4, the cover portion 22 covers the fixed body 21. Specifically, the cover portion 22 covers the arrangement portion 211 of the fixed body 21. More specifically, the cover portion 22 covers the first surface SF1 of the arrangement portion 211. The cover portion 22 is made of, for example, resin. The cover portion 22 is not limited to being made of resin, and may also be made of metal.

[0085] The cover portion 22 includes a fitting portion 22a, an end portion 22b on one direction D11 side in the first direction D1, and an end portion 22c on the other direction D12 side in the first direction D1.

[0086] The fitted portion 22a protrudes in one direction D31 of the third direction D3 beyond the end portions 22b and 22c. The fitted portion 22a corresponds to an example of a "covering portion." The fitted portion 22a covers the flat portion 211B. The length L2 of the fitted portion 22a in the second direction D2 is equal to or less than the length L1 of the arrangement portion 211 in the second direction D2. In other words, the length L2 of the fitted portion 22a in the second direction D2 is not greater than the length L1 of the arrangement portion 211 in the second direction D2.

[0087] For example, if the length of the cover portion in the second direction D2 is longer than the length of the fixed body, when an attempt is made to grasp the fixed body with the index finger and thumb beyond the cover portion, the cover portion will prevent the user from grasping the end of the arrangement portion of the fixed body on the second direction D2 side, the first side surface portion, and the second side surface portion. On the other hand, because the length L2 of the cover portion 22 in the second direction D2 is equal to or less than the length L1 of the arrangement portion 211, it is easy to grasp the cover portion 22 and the fixed body 21. In other words, when inserting the fixed body 21 into the third opening H3 of the wall W, it is easy to grasp the cover portion 22 and the fixed body 21. As a result, the efficiency of the work of attaching the lighting unit 20 to the housing 40 is improved.

[0088] Although it has been described that the length L2 of the fitting portion 22a is equal to or less than the length L1 of the arrangement portion 211, the length L2 of the fitting portion 22a may be the same as the length L1 of the arrangement portion 211. In other words, the side wall portion 222 of the fitting portion 22a and the side wall portion 212 are flush with each other. Therefore, even when the cover portion 22 is placed on the fixed body 21, it is easy to grip the cover portion 22 and the fixed body 21.

[0089] The fitting portion 22a includes a surface portion 221 and a sidewall portion 222. The surface portion 221 is a plate-like member formed in a substantially rectangular shape. A fifth opening H5 is formed in the surface portion 221, penetrating the surface portion 221. The fifth opening H5 is circular. The size of the fifth opening H5 is larger than the size of the sixth opening H6 of the fixed body 21. The inner diameter of the fifth opening H5 is smaller than the outer diameter of the lighting device 23. The sidewall portion 222 extends from the surface portion 221 toward the other direction D32 of the third direction D3. The sidewall portion 222 extends along the first direction D1 and is formed in a rectangular ring shape.

[0090] 1 and 2, when viewed from the third direction D3, the shape of the outer edge of the surface portion 221 of the fitting portion 22a is substantially the same as the shape of the first opening H1. The shape of the outer edge of the fitting portion 22a is also substantially the same as the shape of the first opening H1. That is, the outer size of the fitting portion 22a is smaller than the size of the edge of the first opening H1 by a predetermined dimension. The predetermined dimension is a dimension such that, when the fitting portion 22a is fitted into the first opening H1, a small gap is formed between the fitting portion 22a and the first opening H1.

[0091] For example, the first predetermined dimensions are set so that the width and length of the fitting portion 22a are smaller than the width and length of the first opening H1 by approximately 1 to 2 mm, respectively. As a result, the fitting portion 22a can be fitted into the first opening H1. In addition, in this embodiment, the fitting portion 22a can be fitted into the first opening H1 via the second opening H2. By fitting the fitting portion 22a into the first opening H1, the first opening H1 is substantially blocked by the lighting unit 20.

[0092] 4, 5, 8, and 9, the end portion 22b is a plate-shaped member and extends from an end portion of the side wall portion 222 on the other direction D32 side of the third direction D3 toward one direction D11 side of the first direction D1.

[0093] The end portion 22b has a third through-hole H11, a through-hole H13, a through-hole H15, a through-hole H17, and a notch H19.

[0094] The end portion 22b has a third through hole H11. The third through hole H11 penetrates in the third direction D3. A screw B3 is inserted into the third through hole H11. As shown in FIG. 9, when the cover portion 22 covers the fixed body 21, the third through hole H11 is aligned with the first through hole H21 of the arrangement portion 211 in the third direction D3. In other words, the third through hole H11 and the first through hole H21 communicate with each other in the third direction D3. The third through hole H11 is larger than the first through hole H21.

[0095] 9, the end portion 22b does not cover the first through hole H21. In other words, the first through hole H21 can be seen from the third through hole H11. Therefore, the fixed body 21 can be attached to the housing 40 with the cover portion 22 attached to the fixed body 21. In other words, compared to a conventional cover portion that does not have a through hole at its end through which the screw B3 is inserted, the work of removing the cover portion 22 and exposing the first through hole H21 of the fixed body 21 when attaching the fixed body 21 to the housing 40 can be reduced. This makes it easier to attach the fixed body 21 to the housing 40.

[0096] The third through hole H11 is aligned with the first through hole H21 and the mounting hole H33 (see FIG. 3) of the first mounting piece 425 in the third direction D3. That is, as shown in FIG. 8, the screw B3 is inserted into the third through hole H11, the first through hole H21, and the mounting hole H33. The screw B3 is fastened by being screwed into the mounting hole H33.

[0097] The through hole H13 penetrates in the third direction D3. The through hole H13 has a circular shape. The through hole H13 is located closer to the one direction D11 side in the first direction D1 than the third through hole H11. As shown in FIG. 9, the through hole H13 is aligned with the mounting hole H23 in the third direction D3. That is, the through hole H13 and the mounting hole H23 communicate with each other in the third direction D3. Also, as shown in FIG. 2, the screw B1 is inserted through the through hole H13 and the mounting hole H23. The screw B1 is fastened by being screwed into the mounting hole H23. As a result, the one direction D11 side of the first direction D1 of the second plate 10B is attached to the fixed body 21.

[0098] The through hole H15 penetrates in the third direction D3. The through hole H15 has a circular shape. The through hole H15 is located closer to one direction D21 in the second direction D2 than the through hole H13. As shown in FIG. 9, the through hole H15 has an edge that is larger than the outer edge of the protrusion P25. When the cover portion 22 covers the fixed body 21, the protrusion P25 of the fixed body 21 is inserted into the through hole H15. In other words, when the cover portion 22 covers the fixed body 21, the through hole H15 is located at the position of the protrusion P25. The through hole H15 corresponds to an example of a "second mark portion."

[0099] Therefore, the cover part 22 can be attached to the fixed body 21 using the through hole H15 and the protrusion P25 as markers. By aligning the through hole H15 with the protrusion P25, the positions of the attachment hole H23 and the through hole H13, and the positions of the third through hole H11 and the first through hole H21 can be aligned. Furthermore, by making the portion corresponding to the protrusion P25 the through hole H15, the worker can visually confirm the protrusion P25 through the through hole H15. Therefore, after confirming that the protrusion P25 has been inserted into the through hole H15, the worker can insert the screw B3 into the third through hole H11 and the first through hole H21.

[0100] The through hole H17 is an opening. The through hole H17 penetrates in the third direction D3. The through hole H17 has a rectangular shape. The rectangular through hole H17 corresponds to an example of a "second mark portion." The through hole H17 has a different shape from the third through hole H11, the through hole H13, and the through hole H15, which are located at the end portion 22b. The position of the through hole H17 corresponds to the position of the mark portion M27. When the cover portion 22 covers the fixed body 21, the through hole H17 overlaps with the mark portion M27. Therefore, even when the cover portion 22 is attached to the fixed body 21, the worker can recognize the attachment direction of the fixed body 21. As a result, it is possible to prevent the lighting unit 20 from being attached to the housing 40 in an incorrect orientation.

[0101] The cutout portion H19 is located closer to one direction D21 in the second direction D2 than the third through hole H11. The cutout portion H19 is aligned with the through hole H29 of the fixed body 21 in the third direction D3. An operator can visually recognize the through hole H29 through the cutout portion H19. In other words, the through hole H29 is exposed from the cutout portion H19.

[0102] The end portion 22c is a plate-shaped member and extends from an end portion of the side wall portion 222 on the other side D32 of the third direction D3 toward the other side D12 of the first direction D1.

[0103] The shapes of the end 22c and the end 22b are different. Specifically, the end 22b has a notch H19 on the one side D21 of the second direction D2, while the end 22c does not have a notch. Therefore, the worker can recognize the mounting direction of the cover portion 22 based on the presence or absence of the notch H19. As a result, the work efficiency when mounting the cover portion 22 to the fixed body 21 is improved.

[0104] The end portion 22c has a fourth through-hole H12, a through-hole H14, and a through-hole H16.

[0105] The fourth through hole H12 penetrates in the third direction D3. A screw B3 is inserted into the fourth through hole H12. As shown in Fig. 9, when the cover portion 22 covers the fixed body 21, the fourth through hole H12 is aligned with the second through hole H22 of the arrangement portion 211 in the third direction D3. The fourth through hole H12 is larger than the second through hole H22.

[0106] 9, the end 22c does not cover the second through hole H22. In other words, the second through hole H22 can be seen from the fourth through hole H12. Therefore, the fixed body 21 can be attached to the housing 40 without removing the cover part 22. In other words, compared to a conventional cover part that does not have a through hole at its end through which the screw B4 is inserted, it is easier to attach the fixed body 21 to the housing 40.

[0107] The fourth through hole H12 is aligned in the third direction D3 with the second through hole H22 and the mounting hole H32 (see FIG. 3) of the second mounting piece 426. That is, as shown in FIG. 8, the screw B4 is inserted into the fourth through hole H12, the second through hole H22, and the mounting hole H32. The screw B4 is fastened by being screwed into the mounting hole H32.

[0108] The through hole H14 penetrates in the third direction D3. The through hole H14 has a circular shape. The through hole H14 is located closer to the other direction D12 of the first direction D1 than the fourth through hole H12. As shown in FIG. 9, the through hole H14 is aligned with the mounting hole H24 in the third direction D3. That is, the through hole H14 and the mounting hole H24 communicate with each other in the third direction D3. As shown in FIG. 2, the screw B2 is inserted through the through hole H14 and the mounting hole H24. The screw B2 is fastened by being screwed into the mounting hole H24. As a result, the other direction D12 side of the first direction D1 of the second plate 10B is attached to the fixed body 21.

[0109] The through hole H16 penetrates in the third direction D3. The through hole H16 has a circular shape. The through hole H16 is located on the other direction D22 side of the second direction D2 than the through hole H14. As shown in FIG. 9, the through hole H16 has an edge that is larger than the outer edge of the protrusion P26. When the cover portion 22 covers the fixed body 21, the protrusion P26 of the fixed body 21 is inserted into the through hole H16. In other words, when the cover portion 22 covers the fixed body 21, the through hole H16 is located at the position of the protrusion P26. The through hole H16 corresponds to an example of a "second mark portion."

[0110] Therefore, the cover part 22 can be attached to the fixed body 21 using the through hole H16 and the protrusion P26 as markers. By aligning the through hole H16 with the protrusion P26, the positions of the attachment hole H24 and the through hole H14, and the positions of the fourth through hole H12 and the second through hole H22 can be aligned. Furthermore, by designating the portion corresponding to the protrusion P26 as the through hole H16, the worker can visually confirm the protrusion P26 through the through hole H16. Therefore, after confirming that the protrusion P26 has been inserted into the through hole H16, the worker can insert the screw B4 into the fourth through hole H12 and the second through hole H22.

[0111] In this embodiment, even when the second plate 10B is attached to the lighting unit 20, the screws B3 and B4 are located inside the second opening H2 of the second plate 10B. That is, the third through-hole H11 and the first through-hole H21, and the fourth through-hole H12 and the second through-hole H22 are located inside the second opening H2 in a state in which the second plate 10B is fixed to the lighting unit 20. That is, the screws B3 and B4 can be removed without removing the second plate 10B.

[0112] Therefore, even when the second plate 10B is attached to the lighting unit 20, the lighting unit 20 can be removed from the housing 40. Furthermore, even when the second plate 10B is attached to the lighting unit 20, the lighting unit 20 can be attached to the housing 40. That is, compared to a second plate that covers the screw B3, the third through-hole H11, the first through-hole H21, and the screw B4, the fourth through-hole H12, and the second through-hole H22, the work of removing the second plate is not required. Therefore, it is easy to remove the lighting unit 20 from the wall surface W.

[0113] Next, the accommodation section 24 will be described in detail with reference to Figures 2 to 5 and 8 to 10. Figure 10 is a view of the lighting unit 20 shown in Figure 4 as seen from the other direction D32 side of the third direction D3.

[0114] As shown in FIG. 5, the accommodation section 24 is a hollow member. In the accommodation section 24, for example, a circuit board (not shown) of the lighting device 23 and wiring (not shown) for transmitting power to the lighting device 23 are arranged. The circuit board and wiring of the lighting device 23 correspond to an example of a "part of an electrical device." The circuit board of the lighting device 23 is, for example, a lighting circuit board that supplies a predetermined amount of power to the light source 23a. The accommodation section 24 is made of metal, for example, in consideration of heat dissipation. As shown in FIGS. 4 and 5, the accommodation section 24 is arranged on the second surface SF2 side of the fixed body 21.

[0115] As shown in FIG. 10 , at least one of the first side wall 212A and the second side wall 212B is spaced apart from the housing 24. Therefore, a gap is formed between the first side wall 212A and the housing 24 or between the second side wall 212B and the housing 24. Specifically, the length L4 of the housing 24 in the second direction D2 is shorter than the length L1 of the fixed body 21 in the second direction D2. Furthermore, the housing 24 is disposed closer to the first side wall 212A than the second side wall 212B. Therefore, a gap is formed between the housing 24 and the second side wall 212B. The width of the gap in the second direction D2 is length L3. As shown in FIG. 10 , the wiring A can be disposed in the gap. This prevents the wiring A from moving outside the fixed body 21. As a result, when the lighting unit 20 is attached to the housing 40, the wiring A is prevented from being pinched between the wall W and the housing 40. Furthermore, the wiring A can be prevented from being exposed in one direction D31 of the third direction D3 beyond the fixed body 21.

[0116] The housing 24 of the lighting unit 20 is housed in a housing 41. A power distribution line (not shown) connected to an external power supply is drawn into the housing 41 shown in FIG. 3. That is, the housing 41 houses the lighting circuit board of the lighting unit 20, a wiring A connected to the external power supply, a connection terminal B connected to one end of the wiring A, and a portion of the power distribution line connected to the external power supply. Inside the housing 41, the power distribution line connected to the external power supply is connected to the connection terminal B.

[0117] 10, the wiring A is arranged between the housing portion 24 and the second side wall portion 212B, but this is not limiting. For example, the wiring A may be arranged on the bottom wall 241 side of the housing portion 24. In this case, the wiring A is arranged between the housing 40 and the housing portion 24.

[0118] As shown in FIGS. 4 and 5, the accommodation section 24 is formed in the shape of a bottomed box having a seventh opening H7. The accommodation section 24 has a bottom wall 241 and side walls 242, 243, 244, and 245. The bottom wall 241 faces the second surface SF2 of the fixed body 21. The bottom wall 241 has a flat plate shape. The side walls 242 to 245 extend from the bottom wall 241 toward one direction D31 in the third direction D3. The side walls 242 to 245 define the seventh opening H7.

[0119] The side wall 243 faces the side wall 245. The side wall 243 is located at an end of the bottom wall 241 on the one direction D21 side in the second direction D2. The side wall 244 faces the side wall 242. The side wall 244 is located at an end of the bottom wall 241 on the other direction D12 side in the first direction D1.

[0120] The side wall 242 faces the side wall 244. The side wall 242 is located closer to the side wall 244 in the direction D11 in the first direction D1.

[0121] The side wall 242 has an attachment piece 246. The attachment piece 246 attaches the accommodation section 24 to the fixed body 21. The attachment piece 246 extends from an end of the side wall 242 in one direction D31 of the third direction D3 toward the one direction D31 side in the third direction D3, and further extends toward the one direction D11 side in the first direction D1. The attachment piece 246 has a plate shape bent by 90 degrees. The attachment piece 246 has a shape in which a rectangular flat plate is bent by 90 degrees halfway.

[0122] The mounting piece 246 is inserted into the through hole H29 shown in FIG. 4. The mounting piece 246 inserted into the through hole H29 is located on the first surface SF1 side of the fixed body 21, as shown in FIGS. 4 and 9. When the cover portion 22 is placed on the fixed body 21, the position of the mounting piece 246 inserted into the through hole H29 coincides with the position of the notch H19 of the cover portion 22. Therefore, as shown in FIG. 9, when the cover portion 22 is placed on the fixed body 21, the mounting piece 246 is visible. When the cover portion 22 is placed on the fixed body 21, the cover portion 22 does not overlap the mounting piece 246, so the thickness in the third direction D3 can be reduced.

[0123] Furthermore, the mounting piece 246 extends from the end of the side wall 242 in one direction D31 of the third direction D3, and therefore protrudes in the third direction D3 beyond the ends of the side walls 242 to 245 in the one direction D31 of the third direction D3. This makes it easy to align the accommodation portion 24 with the second surface SF2 of the fixed body 21 after the mounting piece 246 is inserted into the through hole H29.

[0124] Furthermore, since the accommodation portion 24 is fixed by inserting the mounting piece 246 into the through hole H29, no fastening member is required when fixing the one direction D11 side of the first direction D1 of the accommodation portion 24. This makes it easier to assemble the lighting unit 20.

[0125] The side wall 245 faces the side wall 243. The side wall 245 is located on the other direction D22 side of the second direction D2 than the side wall 243. The side wall 245 has a notch H31, a through hole H39, an attachment piece 247, and a protrusion 248.

[0126] The cutout portion H31 is cut out in the second direction D2. In the side wall 245, the cutout portion H31 is arranged on the seventh opening H7 side. The cutout portion H31 becomes smaller as it moves closer to the seventh opening H7 side. As shown in FIG. 10 , the wiring A from the accommodation portion 24 passes through the cutout portion H31.

[0127] The mounting piece 247 is located on the other direction D12 side of the side wall 245 in the first direction D1. The mounting piece 247 has a through hole H38. When the accommodation unit 24 is attached to the fixed body 21, the through hole H38 is aligned with the mounting hole H28 of the fixed body 21 in the third direction D3. As shown in FIG. 10 , a screw B5 is inserted into the through hole H38 and the mounting hole H28. A thread is formed in the mounting hole H28, so the screw B5 is fastened in the mounting hole H28. The accommodation unit 24 is fixed to the fixed body 21 by the mounting piece 246 and the mounting piece 247.

[0128] The through hole H39 penetrates in the second direction D2 and has a U-shape.

[0129] The protrusion 248 extends in the first direction D1. The protrusion 248 is a portion that remains on the side wall 245 when the U-shaped through hole H39 is formed. The end of the protrusion 248 in one direction D11 of the first direction D1 extends in the third direction D3. The protrusion 248 is used to fix the wiring A. For example, as shown in FIG. 10, the protrusion 248 is bound together with the wiring A by a binding band (not shown) or the like.

[0130] Next, the lighting device 23 will be described in detail with reference to Figures 5, 6, and 8. The lighting device 23 includes a light source 23a, a socket 23b, a cover member 23d, a cylindrical body 23f, and a shaft body 23j.

[0131] Light source 23a is, for example, an LED (Light Emitting Diode). Light source 23a is installed inside cylindrical body 23f. Specifically, light source 23a is placed in socket 23b arranged inside cylindrical body 23f. Light from light source 23a is emitted from an opening of cylindrical body 23f.

[0132] The light source 23a is attached to the socket 23b. The socket 23b has a terminal that is electrically connected to a wire that supplies power to the light source 23a. The socket 23b is made of an insulating resin material such as PBT.

[0133] The cover member 23d closes the opening of the cylindrical body 23f.

[0134] The shaft 23j is attached to the flat plate portion 211B of the fixed body 21. The shaft 23j protrudes from the flat plate portion 211B toward one direction D31 in the third direction D3 and toward the other direction D32 in the third direction D3. The shaft 23j is supported by the flat plate portion 211B so as to be rotatable around the axis of the shaft 23j. The shaft 23j is made of metal, but may also be made of ceramic, synthetic resin, wood, or the like. The diameter of the end of the shaft 23j on the other direction D32 in the third direction D3 is smaller than the diameter of the sixth opening H6 of the flat plate portion 211B shown in FIG. 5. Furthermore, the diameter of the end of the shaft 23j on the one direction D31 in the third direction D3 is larger than the diameter of the sixth opening H6. Furthermore, the diameter of the end of the shaft 23j on the one direction D31 in the third direction D3 is smaller than the diameter of the fifth opening H5 of the cover portion 22.

[0135] The cylindrical body 23f is a hollow member and supports the light source 23a. As shown in FIG. 8, the cylindrical body 23f is open on one side D31 of the third direction D3. The cylindrical body 23f has a connecting portion 23g. The connecting portion 23g has a rotation axis 23h. The connecting portion 23g connects the shaft body 23j and the cylindrical body 23f. The rotation axis 23h penetrates the connecting portion 23g and the shaft body 23j. The cylindrical body 23f rotates around the rotation axis 23h. A cover member 23d is attached to the cylindrical body 23f between the light source 23a and the opening 213 or at a position that covers the opening 213. The cylindrical body 23f is made of metal, for example, in consideration of heat dissipation. The diameter of the cylindrical body 23f is larger than the diameter of the fifth opening H5 of the cover portion 22.

[0136] The lighting device 23 can change the direction of light emission from the cylindrical body 23f by adjusting the rotation angle of the shaft body 23j around its axis and the rotation angle of the rotation shaft around its axis, thereby changing the orientation of the cylindrical body 23f.

[0137] In this embodiment, when assembling the lighting unit 20, as shown in FIG. 5 , the shaft 23j is inserted into the sixth opening H6 of the flat plate portion 211B of the fixed body 21, and the shaft 23j is fixed to the fixed body 21. Next, the cover portion 22 is placed on the fixed body 21. At this time, the shaft 23j protrudes from the fifth opening H5 of the cover portion 22 toward one direction D31 in the third direction D3. Next, the connecting portion 23g of the cylindrical body 23f is attached to the shaft 23j. This makes it possible to attach the lighting device 23 to the fixed body 21 even if the diameter of the cylindrical body 23f is larger than the diameter of the fifth opening H5. Next, the accommodation portion 24 is attached to the fixed body 21. Specifically, the attachment piece 246 of the accommodation portion 24 is inserted into the through hole H29 of the fixed body 21 from the second surface SF2 side of the fixed body 21. The attachment piece 246 that passes through the through hole H29 of the fixed body 21 is positioned on the first surface SF1 side of the fixed body 21. Next, the through hole H38 of the mounting piece 247 of the accommodating portion 24 and the mounting hole H28 of the fixed body 21 are aligned in the third direction D3. Then, as shown in FIG. 10 , the screw B5 is inserted into the mounting hole H28 and the through hole H38 to fix the accommodating portion 24 to the fixed body 21.

[0138] The cover portion 22 is supported by the shaft 23j between the cylindrical body 23f and the fixed body 21. Therefore, the cover portion 22 is rotatable about the shaft 23j. When placing the cover portion 22 on the fixed body 21, the worker aligns the positions of the protrusion P25 of the fixed body 21, which serves as a marker, with the through-hole H15 of the cover portion 22, and the protrusion P26 of the fixed body 21 with the through-hole H16 of the cover portion 22. Specifically, the worker inserts the protrusion P25 of the fixed body 21 into the through-hole H15 of the cover portion 22 and the protrusion P26 of the fixed body 21 into the through-hole H16 of the cover portion 22, thereby aligning the cover portion 22 and the fixed body 21. Furthermore, when the cover portion 22 and the fixed body 21 are aligned, the mark portion M27 is exposed from the through-hole H17 of the cover portion 22. Therefore, the lighting unit 20 can be attached to the housing 40 in the direction intended by the designer.

[0139] [Variation 1] Next, lighting device 100 according to Modification 1 of the present embodiment will be described with reference to Figures 1 to 7 and 9 to 11. Lighting device 100 of Modification 1 differs from lighting device 100 of the present embodiment mainly in that a pair of side wall portions 212 of fixed body 21 extend into fourth opening H4 of housing 40. Below, the differences between Modification 1 and the present embodiment will be mainly described.

[0140] FIG. 11 is a diagram schematically showing a cross section of lighting device 100 according to this embodiment.

[0141] 11, the mounting portion 42 of the housing 40 of the first modification is inserted into the third opening H3 of the wall surface W. Specifically, a portion of the side wall portion 422 of the mounting portion 42 is inserted into the third opening H3 of the wall surface W. That is, in the first modification, the fourth opening H4 of the second flat plate portion 423 is smaller than the third opening H3.

[0142] Specifically, the length L13 of the second flat plate portion 423 in the first direction D1 is shorter than the length L11 of the third opening H3 in the first direction D1 shown in FIG. 3. Furthermore, the length of the second flat plate portion 423 in the second direction D2 is shorter than the length of the third opening H3 in the second direction D2. Therefore, when the housing 40 is attached to the wall surface W, the side wall portion 422 intrudes into the third opening H3. For this reason, in the first modification, when the housing 40 is attached to the wall surface W, the edge E40 of the second flat plate portion 423 becomes more easily visible from the third opening H3.

[0143] As shown in FIG. 11, the fixed body 21 of Modification 1 includes an arrangement portion 211 and a pair of side wall portions 212. As shown in FIGS. 5 and 6, the pair of side wall portions 212 protrude from the end portions of the arrangement portion 211 in the second direction D2. The pair of side wall portions 212 protrude in the other direction D32 of the third direction D3. In other words, the pair of side wall portions 212 extend toward the fourth opening H4. The pair of side wall portions 212 also extend in the first direction D1.

[0144] The length of the pair of side wall portions 212 in the first direction D1 in Modification 1 is shorter than the length L12 of the fourth opening H4 in the first direction D1. Therefore, the pair of side wall portions 212 can enter the fourth opening H4. In this case, the side wall portions 212 are supported by the edge E40 of the fourth opening H4. This allows the fixed body 21 to be easily fixed to the first mounting piece 425 and the second mounting piece 426. This facilitates the work of aligning the first through hole H21 of the fixed body 21 with the mounting hole H33 of the first mounting piece 425 and the work of aligning the second through hole H22 of the fixed body 21 with the mounting hole H32 of the second mounting piece 426. As a result, the efficiency of the work when attaching the lighting unit 20 to the housing 40 is improved.

[0145] Furthermore, the first side wall 212A faces the edge of the fourth opening H4 on the one direction D21 side in the second direction D2. That is, the first side wall 212A contacts the edge of the fourth opening H4 on the one direction D21 side in the second direction D2. In this case, movement of the fixed body 21 in the one direction D21 side in the second direction D2 is restricted. As a result, when the fixed body 21 is attached, excessive movement of the fixed body 21 in the one direction D21 side in the second direction D2 can be suppressed.

[0146] Additionally, the second side wall portion 212B faces the edge of the fourth opening H4 on the other side D22 in the second direction D2. That is, the second side wall portion 212B comes into contact with the edge of the fourth opening H4 on the other side D22 in the second direction D2. In this case, movement of the fixed body 21 in the other side D22 in the second direction D2 is restricted. As a result, when the fixed body 21 is attached, excessive movement of the fixed body 21 in the other side D22 in the second direction D2 can be suppressed.

[0147] [Variation 2] Next, lighting device 100 according to Modification 2 of the present embodiment will be described with reference to Fig. 12. Lighting device 100 according to Modification 2 differs from lighting device 100 according to the present embodiment mainly in that it includes operation unit 80 in addition to lighting unit 20. Below, differences between Modification 2 and the present embodiment will be mainly described. Fig. 12 is a diagram showing lighting device 100 according to Modification 2 of the present embodiment.

[0148] The operation unit 80 operates the lighting unit 20. The operation unit 80 is an example of an "electrical equipment unit." The operation unit 80 is attached to the plate portion 10. The operation unit 80 is aligned with the lighting unit 20 in the second direction D2.

[0149] The plate portion 10 of the second modification surrounds the lighting unit 20 and the operation unit 80. The plate portion 10 is installed on a wall surface W. The plate portion 10 of the second modification has a first opening H1 and an eighth opening H8. The eighth opening H8 and the first opening H1 are separated by a partition 10a of the plate portion 10. The first opening H1 is located on one direction D21 side of the second direction D2. The eighth opening H8 is located on the other direction D22 side of the second direction D2. The eighth opening H8 opens in the third direction D3. The operation unit 80 is inserted into the eighth opening H8.

[0150] The operation unit 80 includes a first operation part 81 and a second operation part 82. The first operation part 81 is a rotating dial. The first operation part 81 is an operation part for adjusting the light intensity and / or light color of the light source 21g. The first operation part 81 adjusts the light intensity and / or light color of the light source 21g according to the rotation angle of the dial.

[0151] The second operating unit 82 is a switch. The second operating unit 82 is an operating unit for switching the power supply of the light source 21g between an on state and an off state. Each time the second operating unit 82 is pressed, the power supply of the light source 21g is alternately switched between the on state and the off state.

[0152] The outer shape of the operation unit 80 is substantially the same as the shape of the edge of the eighth opening H8. The outer size of the operation unit 80 is smaller than the size of the eighth opening H8 by a predetermined dimension. The predetermined dimension is a dimension that allows a slight gap to be formed between the operation unit 80 and the eighth opening H8 when the operation unit 80 is fitted into the eighth opening H8. For example, the predetermined dimensions are set so that the width and length dimensions of the outer shape of the operation unit 80 are approximately 1 to 2 mm smaller than the width and length dimensions of the eighth opening H8. As a result, the operation unit 80 can be fitted into the eighth opening H8. When the operation unit 80 is fitted into the eighth opening H8, the eighth opening H8 is substantially blocked by the operation unit 80.

[0153] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments and can be embodied in various forms without departing from the spirit of the present invention. The drawings mainly show each component in a schematic manner to facilitate understanding, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of creating the drawings. Furthermore, the speed, material, shape, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within a range that does not substantially deviate from the configuration of the present invention.

[0154] (1) In the present embodiment, the lighting unit 20 is attached to the housing 40, but this is not limiting. The lighting unit 20 may be fixed directly to the wall W. In this case, there is no housing 40 fixed to the wall W, and the lighting unit 20 is inserted into the third opening H3 of the wall W and fixed directly to the wall W with screws B3 and B4.

[0155] Even when the housing 40 is not used, the end E3 of the first side wall portion 212A fits along the edge E30 of the third opening H3, which prevents the fixed body 21 from moving excessively and facilitates positioning of the fixed body 21 and the housing 40. As a result, the work of attaching the lighting unit 20 to the wall surface W becomes easier.

[0156] The lighting unit 20 may be fixed to the wall surface W with screws B1 and B2. Specifically, the screw B1 is inserted into the through hole H13 and the mounting hole H23 and reaches the wall surface W. Furthermore, the screw B2 is inserted into the through hole H14 and the mounting hole H24 and reaches the wall surface W. As a result, the fixing body 21, the cover portion 22, and the second plate 10B are fixed to the wall surface W with the screws B1 and B2. [Industrial Applicability]
