Description

Technical Field

[0001] This specification relates to an elevator lighting device in which the power supply of a downlight lighting fixture can be easily replaced, and a method for manufacturing the elevator lighting device.

Background Art

[0002] As a lighting device for the ceiling of a building, a lighting device using a downlight is known. In recent years, LEDs (Light Emitting Diodes) are often used in downlight lighting devices. Since LEDs require a DC power supply, a power supply unit for converting AC to DC is required (for example, Patent Document 1). In addition, a downlight lighting device may be installed as a light source for the ceiling lighting of an elevator car in order to improve the design. Similar to a building, a downlight lighting device using LEDs installed on the ceiling of an elevator car includes a lighting unit (downlight) that illuminates the inside of the elevator car and a power supply unit that supplies power to the lighting unit. The lighting unit is inserted from inside the elevator car into a hole opened in the ceiling, and is fixed to the ceiling by a mounting spring (mounting portion) formed by a leaf spring provided in the lighting unit. Therefore, the lighting unit is detachably fixed to the ceiling from inside the elevator car (for example, Patent Document 2). The mounting spring is configured in a U-shape on the side portion of the lighting unit. When inserted into the hole, it flexes, and after insertion, while spreading, it presses or fits with the structure around the hole or on the back surface of the ceiling with the tip portion of the U-shape, and fixes the lighting unit to the ceiling. By the way, when a downlight lighting device using LEDs is used for building lighting, since the ceiling of the building does not move and there is no risk of vibration or noise, the power supply unit is often placed without being fixed to the back of the ceiling. On the other hand, when using a downlight lighting device using LEDs on the ceiling of an elevator, if the power supply unit is placed without being fixed to the back surface of the ceiling as in the case of a building, there is a risk of causing vibration or noise. Therefore, when using a downlight lighting device using LEDs on the ceiling of an elevator, it may be screwed to the back surface of the ceiling using screw holes or the like provided in the power supply unit. In this case, when replacing the LED downlight lighting fixture for maintenance, the lighting unit could be removed from the inside of the elevator car, but it was necessary to move to the top of the elevator car to remove the power supply unit, which was screwed to the ceiling. Generally, since the lifespan of the LED lighting unit and power supply unit are considered to be the same and replacement is recommended, when replacing an LED downlight lighting system, both the lighting unit and the power supply unit must be replaced. However, this requires work to be performed both inside and above the train car, which presents a problem of poor maintenance efficiency. [Prior art documents] [Patent Documents]

[0010] First, before describing the configuration of the elevator lighting device and the method for manufacturing the elevator lighting device according to the present invention, an elevator car equipped with the elevator lighting device according to the present invention will be described with reference to Figure 1. Note that the following embodiments are illustrative examples to aid in understanding the configuration of the elevator car, etc., and do not limit the configuration of the elevator lighting device and the method for manufacturing the elevator lighting device according to the present invention.

[0011] Figure 1 is a schematic perspective view showing the interior of an elevator car 1, which is one embodiment of the present invention. As shown in Figure 1, the elevator car 1 communicates with the landing by opening and closing the entrance and exit, for example, by the opening and closing of the car doors 3,3. The elevator car 1 is equipped with side walls 4,4 adjacent to the car doors 3,3. An elevator car control panel 2 for registering the destination floor of the elevator car 1 is provided on one of the side walls 4 (in this embodiment, it is provided on one of the side walls 4). In addition to the car doors 3,3, the elevator car 1 is also composed of a ceiling 5 and a floor 6, as well as side walls 4 and side walls 7 that constitute the wall surface.

[0012] In each figure, the first direction D1 is the first horizontal direction D1, the second direction D2 is the second horizontal direction D2 which is orthogonal to the first horizontal direction D1, and the third direction D3 is the vertical direction D3 which is orthogonal to each of the horizontal directions D1 and D2 and is the direction in which the elevator car 1 moves up and down. Also, the inner side of the elevator car 1 of the car doors 3, 3, the ceiling 5, the floor 6, the sleeve walls 4 and the side walls 7 is referred to as the inner side, and the hoistway side is also referred to as the outer side or the back side.

[0013] As shown in FIG. 1, in the present embodiment, the ceiling 5 is divided into a plurality of ceiling panels 51 along the first horizontal direction D1 (divided into three in FIG. 1). The ceiling panel 51 is provided with lighting units (downlights) 9 (two in the ceiling panel 51 on the car door 3 side in FIG. 1).

[0014] Next, the elevator lighting device 8 according to the present embodiment will be described with reference to FIGS. 2 to 4. As shown in FIGS. 2 and 3(a), two elevator lighting devices 8 are provided apart from each other in the first horizontal direction D1 on the back surface of the ceiling panel 51. Since the two elevator lighting devices 8 are configured in a left-right reversed manner and have the same configuration, the present embodiment will be described using the left elevator lighting device 8 in FIG. 3(a).

[0015] In the present embodiment, the ceiling panel 51 has its four sides bent in four directions. Specifically, the four sides of a rectangular steel plate extending in the first horizontal direction D1 and the second horizontal direction are bent to the back surface side to form the first bent portion 511, and further, the tip of the bent first bent portion 511 is bent toward the opposite side of the rectangular steel plate to form the second bent portion 512.

[0016] On the back surface of the ceiling panel 51, a U-shaped bracket 11 is fixed in the second lateral direction D2 view. The bracket 11 is fixed by a known fixing method such as screwing, adhesive fixing, or welding fixing. The second bent portion 512 is partially cut out with a width substantially the same as the width of the bracket 11 in the second lateral direction D2 up to the connection portion with the first bent portion 511. The bracket 11 is fixed to the ceiling panel 51 with one end in contact with the first bent portion 511 at the cut-out portion. The bracket 11 is made of a ferromagnetic material. The bracket 11 is composed of, for example, a steel plate, but may be composed of other known ferromagnetic materials.

[0017] At the end of the bracket 11 on the side of the first bent portion 511, a hat-shaped cover 12 without one flange and opening in the first lateral direction D1 is fixed. In this embodiment, the flange portion is screwed to the bracket 11 in a cantilever manner. Note that the cover 12 may be fixed by another known method such as welding fixing.

[0018] The ceiling panel 51 is provided with a hole 513 at the position of the lighting unit 9, and the bracket 11 fixed to the ceiling panel 51 is also provided with a hole 211 that is substantially the same as or slightly larger than the hole 513 at the same position as the hole 513. A U-shaped attachment portion 22 is fixed to the bracket 11 at the same position as the hole 513 in the first lateral direction D1 view. The attachment portion 22 fixed to the bracket 11 is also provided with a hole 221 that is substantially the same as or slightly larger than the hole 513 at the same position as the hole 513.

[0019] The lighting unit 9 includes a lighting main body portion 15 composed of a trim 21, a reflector, a light source (LED), a heat sink, a housing, etc., and an attachment portion 17 for fixing the lighting unit 9. In this embodiment, the lighting main body portion 15 has a cylindrical shape, and a flange-shaped trim 21 is provided inside the ceiling panel 51 of the lighting main body portion 15. The reflector is formed in a conical shape with the inside of the elevator car 1 opened at the lighting main body portion 15, and a light source (LED) is provided at the bottom of the reflector. The reflector is painted white or processed into a mirror surface to diffuse the light emitted from the light source (LED).

[0020] The mounting portion 17 is fixed at one end to the trim 21 side of the lighting body 15 and consists of a leaf spring bent in a V-shape away from the lighting body 15. In this embodiment, two mounting portions are provided on both sides of the lighting body 15 in the second lateral direction D2. When the lighting unit 9 is inserted into the hole 513 from the inside of the elevator car 1, the trim 21 is in contact with the inner surface of the ceiling panel 51, and the V-shaped tip of the bent leaf spring of the mounting portion 17 is locked to the tip of each of the U-shaped bent pieces of the mounting portion 22.

[0021] Figure 3(b) is an enlarged bottom view of the main part of section A in Figure 3(a). As shown in Figure 3(b), the elevator lighting device 8 comprises a lighting unit 9, a power supply unit 10 that supplies lighting power to the lighting unit 9, and a power line 16 that connects the lighting unit 9 and the power supply unit 10. The power supply unit 10 comprises a power supply body 14 and leg portions 20 that protrude downward in the vertical direction D3 from both ends of the power supply body 14 in the first horizontal direction D1. In this embodiment, there are two leg portions 20 at each end of the power supply body 14 in the first horizontal direction D1, for a total of four, and each leg portion 20 is provided with a U-shaped hole for fixing.

[0022] Here, the configuration of the power supply unit 10 will be explained using Figure 4. The power supply unit 10 is equipped with an H-shaped base 13. The base 13 consists of a base portion 23 made of, for example, a steel plate, and fastening members 24 are provided at positions corresponding to the U-shaped holes of the leg portions 20 provided on the power supply main body 14, extending upward in the vertical direction D3 from the base portion 23. The fastening members 24 are, for example, clinching stud bolts, and in this embodiment, four are provided to match the number of leg portions 20. The fastening members 24 may also be stud bolts, weld bolts, etc. The base 13 may be rectangular instead of H-shaped.

[0023] The fastening member 24 of the base 13 is inserted into the U-shaped hole of the leg portion 20 of the power supply unit 14, and the power supply unit 14 and the base 13 are screwed together by the fastening member 25. The engaging portion 18 is attached to the lower side of the base portion 23 in the vertical direction D3. In this embodiment, the engaging portion 18 is a sheet-shaped magnet. The engaging portion 18 is fixed to the base portion 23 by double-sided adhesive tape or adhesive. In this embodiment, of the H-shaped base portion 23, the engaging portion 18 is fixed to the lower side in the vertical direction D3 of the two pieces to which the fastening member 24 is attached. The engaging portion 18 functions as a simple mounting means 28, which will be described later. The power supply unit 10 can be inserted through a hole 513 made in the ceiling panel 51, and can be moved in and out of the inside and outside of the elevator car 1 through the hole 513.

[0024] Next, we will explain how to install the lighting unit 9 and the power supply unit 10 using Figures 2 and 3.

[0025] For example, when replacing an existing elevator lighting system 8, the lighting unit 9 and power supply unit 10 are routed into the elevator car 1. In this case, the lighting unit 9 and the power supply unit 10 are connected by a power line 16. In addition, a cable (not shown) wired from an AC power source such as a commercial power supply is connected to the power supply unit 10 to a length that allows it to be routed into the elevator car 1. The lighting unit 9, power supply unit 10 and power line 16 are replaced with new parts and connected to the aforementioned cable.

[0026] First, the aforementioned cable is inserted into the hole 513 made in the ceiling panel 51, and then the power supply unit 10 is passed through the hole 513 and inserted into the back surface of the ceiling panel 51. The worker replacing the elevator lighting device 8 inserts their arm through the hole 513 and inserts the power supply unit 10 into the tunnel-shaped space that opens in the first lateral direction D1, formed by the cover 12 fixed to the bracket 11. The cover 12 has a positioning function that indicates the installation position of the power supply unit 10 and a function that protects the connection between the power supply unit 10 and the aforementioned cable from moisture and dust.

[0027] Subsequently, the power supply unit 10 is moved downward in the vertical direction D3 toward the bracket 11, and the engaging portion 18 is brought into contact with the engaged portion 19 formed on at least a part of the bracket 11. In this embodiment, the engaging portion 18 is a magnet and the engaged portion 19 is made of a ferromagnetic material, so the power supply unit 10 is attached to the bracket 11 by magnetic force. In this embodiment, the entire bracket 11 is made of a steel plate which is a ferromagnetic material, so the entire bracket 11 forms the engaged portion 19. With this configuration, the power supply unit 10 can be fixed to the bracket 11 in a single operation by a simple mounting means 28 that does not require screwing or other fastening with tools.

[0028] Based on the above, the elevator lighting device 8 is as in this embodiment. An elevator lighting device 8 is installed on the ceiling 5 of the elevator car 1, The elevator lighting device 8 comprises a lighting unit 9 equipped with a light source and a power supply unit 10 that supplies power to the lighting unit 9. The lighting unit 9 is equipped with a mounting part 17 that is inserted into a hole 513 provided in the ceiling 5 from inside the elevator car 1 and fixed in place. The power supply unit 10, which can be inserted into the hole 513, is attached to the back surface of the ceiling 5 by a simple mounting means 28 that can be fixed with a single operation. This configuration is preferable.

[0029] With this configuration, after inserting a hand through the hole 513 to install the power supply unit 10, the lighting unit 9 is inserted into the hole 513 provided in the ceiling and fixed in place. This makes it possible to install both the lighting unit 9 and the power supply unit 10 from inside the elevator car 1, thereby improving the ease of replacing the elevator lighting device 8.

[0030] Furthermore, the elevator lighting device 8, as in this embodiment, The power supply unit 10 can be removed from the back surface of the ceiling 5 by releasing the simple mounting means 28 with a single operation. This configuration is preferable.

[0031] With this configuration, after removing the lighting unit 9 through the hole 513 provided in the ceiling, the power supply unit 10 can be removed by reaching a hand through the hole 513. This makes it possible to remove both the lighting unit 9 and the power supply unit 10 from inside the elevator car 1, thereby improving the ease of replacing the elevator lighting device 8.

[0032] Furthermore, the elevator lighting device 8, as in this embodiment, The aforementioned simple mounting means 28 is provided with an engaging portion 18 on either the power supply unit 10 or the ceiling 5, and a receiving portion 19 on the other. This configuration is preferable.

[0033] With this configuration, when replacing the elevator lighting device 8, both the lighting unit 9 and the power supply unit 10 can be attached and detached from inside the elevator car 1, thereby providing an elevator lighting device with improved maintainability.

[0034] Furthermore, the elevator lighting device 8, as in this embodiment, The engaging portion 18 is a magnet, and the engaged portion 19 is a ferromagnetic material. This configuration is preferable.

[0035] With this configuration, since the engaging portion 18 is a magnet and the engaged portion 19 is a ferromagnetic material, both the lighting unit 9 and the power supply unit 10 can be attached and detached from the inside of the elevator car 1 without using tools, thereby providing an elevator lighting device 8 with improved maintainability.

[0036] Furthermore, the method for manufacturing the elevator lighting device 8 is as described in this embodiment, A method for manufacturing an elevator lighting device 8 having a lighting unit 9 equipped with a light source and a power supply unit 10 that supplies lighting power to the lighting unit 9, The process involves inserting the power supply unit 10, which is insertable through the hole 513, into the back surface of the ceiling 5 of the elevator car 1, through a hole 513 provided in the ceiling 5 of the elevator car 1. The process involves attaching the power supply unit 10 to the back surface of the ceiling 5 using a simple mounting means 28 that can be fixed in a single operation, The process includes inserting the lighting unit 9 into the hole 513 from inside the elevator car 1 and fixing it with the mounting portion 17 of the lighting unit 9. This configuration is preferable.

[0037] With this configuration, after inserting a hand through the hole 513 to attach the power supply unit 10 to the back surface of the ceiling 5, the lighting unit 9 is inserted into the hole 513 provided in the ceiling and fixed in place. This makes it possible to perform the installation work for both the lighting unit 9 and the power supply unit 10 from inside the elevator car 1, thereby improving the ease of replacing the elevator lighting device 8.

[0038] It should be noted that the elevator lighting device 8 and the method for manufacturing the elevator lighting device 8 are not limited to the configuration of the embodiment described above, nor are they limited to the effects described above. Furthermore, it goes without saying that the elevator lighting device 8 and the method for manufacturing the elevator lighting device 8 can be modified in various ways without departing from the spirit of the present invention. For example, it goes without saying that one or more of the configurations and methods, etc., related to the various modification examples described below can be arbitrarily selected and adopted in the configurations and methods, etc., of the embodiment described above.

[0039] (A) In the elevator lighting device 8 according to the above embodiment, the engaging portion 18 of the simple mounting means 28 is a magnet, and the engaged portion 19 is a ferromagnetic material. However, the elevator lighting device 8 is not limited to this configuration.

[0040] Figure 5 is an enlarged bottom view of the main part of the elevator lighting device 108, which is the same as part A in Figure 3(a) in another embodiment. Figure 5 shows the lighting unit 9, power supply unit 100, power line 16, and simple mounting means 128, etc. in another embodiment. In Figure 5, components identical to those in Figure 3(b) are denoted by the same reference numerals, and some descriptions are omitted.

[0041] A U-shaped bracket 111 is fixed to the back surface of the ceiling panel 51 in a second lateral view D2. The bracket 111 is fixed by known fixing methods such as screwing, adhesive fixing, or welding. The second bent portion 512 is partially cut out to a point where it connects with the first bent portion 511, with a width approximately the same as the width of the bracket 111 in the second lateral view D2. The bracket 111 is fixed to the ceiling panel 51 with one end in contact with the first bent portion 511 at the cut-out portion. For example, the bracket 111 may be made of steel plate.

[0042] The ceiling panel 51 has a hole 513 at the position of the lighting unit 9, and the bracket 111 fixed to the ceiling panel 51 also has a hole 2111 which is approximately the same size as or slightly larger than the hole 513, at the same position as the hole 513. A U-shaped mounting portion 22 is fixed to the bracket 111 in the same position as the hole 513 in the first lateral view D1. The mounting portion 22 fixed to the bracket 111 also has a hole 221 which is approximately the same size as or slightly larger than the hole 513, at the same position as the hole 513.

[0043] As shown in Figure 5, the elevator lighting device 108 comprises a lighting unit 9, a power supply unit 100 that supplies lighting power to the lighting unit 9, and a power line 16 that connects the lighting unit 9 and the power supply unit 100. The power supply unit 100 comprises a power supply body 14 and leg portions 20 that protrude downward in the vertical direction D3 from both ends of the power supply body 14 in the first horizontal direction D1. In this embodiment, there are two leg portions 20 at each end of the power supply body 14 in the first horizontal direction D1, for a total of four, and each leg portion 20 is provided with a U-shaped hole for fixing.

[0044] Here, the configuration of the power supply unit 100 will be explained using Figure 6. The power supply unit 100 is equipped with an H-shaped base 113, and the base 113 is equipped with a base portion 123 made of steel plate, and fastening members 24 are provided at positions corresponding to the U-shaped holes of the leg portions 20 provided on the power supply main body 14, extending upward in the vertical direction D3 from the base portion 123. The fastening members 24 are, for example, clinching stud bolts, and in this embodiment, four are provided to match the number of leg portions 20. Note that the fastening members 24 may be stud bolts, weld bolts, etc.

[0045] The fastening member 24 of the base 113 is inserted into the U-shaped hole of the leg portion 20 of the power supply unit 14, and the power supply unit 14 and the base 113 are screwed together by the fastening member 25. An engaging portion 118 is provided at the end of the base portion 123 on the side of the first bent portion 511 in the first lateral direction D1 in Figure 5 (left side in Figure 5). Specifically, a part of the end of the H-shaped base portion 123 on the side of the first bent portion 511 in the first lateral direction D1 protrudes in a rectangular shape, forming the engaging portion 118 (insert). The engaging portion 118 functions as a simple mounting means 128. The power supply unit 100 can be inserted through a hole 513 made in the ceiling panel 51, and can be moved in and out of the inside and outside of the elevator car 1 through the hole 513.

[0046] A hat-shaped cover 12, which has no flange on one side and opens in the first lateral direction D1, is fixed to the end of the bracket 111 on the side of the first bent portion 511. In this embodiment, the flange portion is cantilevered to the bracket 111 with screws. Note that the cover 12 may be fixed by other known methods such as welding.

[0047] At the end of the bracket 111 on the side of the first bent portion 511, an engaging portion 119 is provided, overlapping with the cover 12 or positioned further towards the first bent portion 511 than the cover 12. The engaging portion 119 is made of spring steel and has an arc shape in a second lateral view D2. A fixing hole (not shown) is made on the side of the engaging portion 119 on the side of the first bent portion 511, and the engaging portion 119 is fixed by a fastening member 27 through the hole (not shown) made in the engaging portion 119 to a fastening member 26 provided extending upward in the vertical direction D3 from the bracket 111. In this other embodiment, the fastening member 26 is, for example, a clinching stud bolt, and two are provided (in Figure 5, one is shown in the foreground of the paper). The fastening member 27 is, for example, a nut. The fastening member 26 may also be a stud bolt or a weld bolt.

[0048] As shown in Figure 5, the engaged portion 119 is arc-shaped, and the power supply unit 100 is fixed by sandwiching the engaged portion 118 between it and the bracket 111 on the lighting unit 9 side.

[0049] Next, using Figure 5, the mounting methods for the lighting unit 9 and the power supply unit 109 in another embodiment will be described.

[0050] For example, when replacing an existing elevator lighting unit 108, the lighting unit 9 and power supply unit 100 are routed into the elevator car 1. In this case, the lighting unit 9 and the power supply unit 100 are connected by a power line 16. In addition, a cable (not shown) wired from an AC power source such as a commercial power supply is connected to the power supply unit 100 to a length that allows it to be routed into the elevator car 1. The lighting unit 9, power supply unit 100 and power line 16 are replaced with new parts and connected to the aforementioned cable.

[0051] First, the aforementioned cable is inserted into the hole 513 made in the ceiling panel 51, and then the power supply unit 100 is passed through the hole 513 and inserted into the back surface of the ceiling panel 51. The worker replacing the elevator lighting device 108 inserts their arm through the hole 513 and inserts the power supply unit 100 into the tunnel-shaped space that opens in the first lateral direction D1, formed by the cover 12 fixed to the bracket 111. The cover 12 has a positioning function that indicates the installation position of the power supply unit 100 and a function that protects the connection between the power supply unit 100 and the aforementioned cable from moisture and dust.

[0052] Subsequently, the power supply unit 100 is slid along the bracket 111 in the first lateral direction D1 toward the first bending portion 511, and the engaging portion (insert) 118 is inserted into the engaged portion (catch) 119. In this other embodiment, the engaging portion 118 is an insert and the engaged portion 119 is a catch, and since they are formed from an arc-shaped spring material, the power supply unit 100 is attached to the bracket 111 by the frictional force between the engaging portion 118 and the engaged portion 119. With this configuration, the power supply unit 100 can be fixed to the bracket 111 in a single operation by a simple mounting means 128 that does not require screwing or other fastening with tools.

[0053] (B) In addition, in the elevator lighting device 8 according to the above embodiment, the engaging portion 18 of the simple mounting means 28 is a magnet, and the engaged portion 19 is a ferromagnetic material. However, the elevator lighting device 8 is not limited to this configuration. For example, the engaging portion 18 and the engaged portion 19 may be hook-and-loop fasteners such as Velcro® or hook-and-loop tape®. Of course, the same function and effect can be obtained with such a configuration as well.

[0054] (C) In addition, in the elevator lighting device 8 according to the above embodiment, the lighting unit 9 is substantially cylindrical, but the configuration is not limited to this. The lighting unit 9 may be polygonal prism shape, such as a substantially rectangular prism.

[0055] (D) Furthermore, although the elevator lighting device 8 according to the above embodiment is equipped with a cover 12, the configuration is not limited to this. The elevator lighting device 8 may be configured without a cover 12.

The power supply unit 200 comprises a power supply body 14 and legs 20 that protrude downward in the vertical direction D3 from both ends of the power supply body 14 in the first horizontal direction D1. In this embodiment, there are two legs 20 at each end of the power supply body 14 in the first horizontal direction D1, for a total of four legs, and each leg 20 is provided with a U-shaped hole for fixing.

[0060] Furthermore, a notch 1122 is provided through the flange portion 1121 that rises in the vertical direction D3 on the first bent portion 511 side of the bracket 112, into which the insertion portion 29, described later, is inserted. In this embodiment, the notch 1122 is rectangular to match the shape of the insertion portion 29 and is cut out to be slightly larger than the width of the insertion portion 29 in the second horizontal direction D2.

[0061] Here, the configuration of the power supply unit 200 will be explained using Figure 8. The power supply unit 200 is equipped with an H-shaped base 213. The base 213 is, for example, a base portion 223 made of steel plate, and fastening members 24 are provided at positions corresponding to the U-shaped holes of the leg portions 20 provided on the power supply main body 14, extending upward in the vertical direction D3 from the base portion 223. The fastening members 24 are, for example, clinching stud bolts, and in this embodiment, four are provided to match the number of leg portions 20. The fastening members 24 may also be stud bolts, weld bolts, etc. The base 213 may be rectangular instead of H-shaped. In addition, an insertion portion 29 is provided at the first lateral D1 end of the base portion 223, protruding convexly from the base portion 223 toward the first bent portion 511.

[0062] The fastening member 24 of the base 213 is inserted into the U-shaped hole of the leg portion 20 of the power supply unit 14, and the power supply unit 14 and the base 213 are screwed together by the fastening member 25. The engaging portion 18 is attached to the lower side of the base portion 223 in the vertical direction D3. In this embodiment, the engaging portion 18 is a sheet-shaped magnet. The engaging portion 18 is fixed to the base portion 223 by double-sided adhesive tape or adhesive. In this embodiment, the engaging portion 18 is fixed to the lower side of the two pieces of the H-shaped base portion 223 to which the fastening member 24 is attached, in the vertical direction D3. The engaging portion 18 functions as a simple mounting means 228, which will be described later. The power supply unit 200 can be inserted through a hole 513 made in the ceiling panel 51, and can be moved in and out of the inside and outside of the elevator car 1 through the hole 513.

[0063] Next, the installation method for the lighting unit 9 and the power supply unit 200 will be explained using Figures 7 and 8.

[0064] For example, when replacing an existing elevator lighting unit 208, the lighting unit 9 and power supply unit 200 are routed into the elevator car 1. In this case, the lighting unit 9 and the power supply unit 200 are connected by a power line 16. In addition, a cable (not shown) wired from an AC power source such as a commercial power supply is connected to the power supply unit 200 to a length that allows it to be routed into the elevator car 1. The lighting unit 9, power supply unit 200, and power line 16 are replaced with new parts and connected to the aforementioned cable.

[0065] First, the aforementioned cable is inserted into the hole 513 made in the ceiling panel 51, and then the power supply unit 200 is passed through the hole 513 and inserted into the back surface of the ceiling panel 51. The worker replacing the elevator lighting device 208 inserts their arm through the hole 513 and inserts the insertion part 29 of the power supply unit 200 into the notch 1122 of the bracket 112. The notch 1122 and insertion part 29 have a positioning function that indicates the installation position of the power supply unit 200, and a function to prevent rattling when the power supply unit 200 is assembled into the ceiling panel 51 at the factory and shipped, and then transported.

[0066] Subsequently, the power supply unit 200 is moved downward in the vertical direction D3 toward the bracket 112, and the engaging portion 18 is brought into contact with the engaged portion 19 formed on at least a part of the bracket 112. In this embodiment, the engaging portion 18 is a magnet and the engaged portion 19 is made of a ferromagnetic material, so the power supply unit 200 is attached to the bracket 112 by magnetic force. In this embodiment, the entire bracket 112 is made of a steel plate which is a ferromagnetic material, so the entire bracket 112 forms the engaged portion 19. With this configuration, the power supply unit 200 can be fixed to the bracket 112 in a single operation by a simple mounting means 228 that does not require screwing or other fastening with tools.

[0067] (F) In addition, in the elevator lighting device 8 according to the above embodiment, the lighting unit 9 and the power supply unit 10 are attached to the ceiling panel 51 via the bracket 11, but the configuration is not limited to this. The elevator lighting device 8 may also be configured such that the lighting unit 9 and the power supply unit 10 are directly attached to the ceiling panel 51 without the bracket 11.

[0068] (G) In addition, in the elevator lighting device 8 according to the above embodiment, two lighting units 9 are attached to both ends of the ceiling panel 51 in the first horizontal direction D1, but the configuration is not limited to this. The elevator lighting device 8 may be configured such that one or more lighting units 9 are attached to the ceiling panel 51 near the center of the first horizontal direction D1.

[0069] (H) The mounting portion 17 for fixing the lighting unit 9 consists of a leaf spring bent in a V-shape away from the lighting body 15, but is not limited to this configuration. The mounting portion 17 may be any other known mounting portion that can be attached and detached from the inside of the elevator car 1.
