Description

[Technical Field]

[0001] The present specification relates to an elevator lighting device that allows easy replacement of the power supply of a downlight lighting fixture, and a method for manufacturing the elevator lighting device. [Background technology]

[0002] Lighting devices using downlights are known as lighting devices for the ceilings of buildings. In recent years, LEDs (Light Emitting Diodes) are often used in downlight lighting devices, and since LEDs require a DC power source, a power supply unit that converts AC to DC is required (for example, Patent Document 1). Furthermore, downlight lighting devices are sometimes installed as light sources for ceiling lighting in elevator cars to improve design. Similar to buildings, LED downlight lighting devices installed on the ceiling of elevator cars include a lighting unit (downlight) that illuminates the interior of the elevator car and a power supply unit that supplies power to the lighting unit. The lighting unit is inserted into a hole in the ceiling from inside the elevator car and is fixed to the ceiling by a leaf spring (mounting unit) attached to the lighting unit. Therefore, the lighting unit is fixed to the ceiling detachably from inside the elevator car (see, for example, Patent Document 2). The mounting spring is configured in a dogleg shape on the side of the lighting unit, and bends when inserted into the hole, and then expands after insertion, with the dogleg tip pushing or fitting into the structure around the hole or on the underside of the ceiling, thereby fixing the lighting unit to the ceiling. When LED downlights are used to illuminate buildings, the ceiling of the building does not move, eliminating the risk of vibration or noise, so the power supply is often placed unsecured above the ceiling. On the other hand, when using LED downlight lighting devices on the ceiling of an elevator, if the power supply unit is not fixed to the underside of the ceiling, as is the case with the building structure, it may cause vibration and noise. Therefore, when using an LED downlight lighting device on the ceiling of an elevator, it was sometimes necessary to screw it to the underside of the ceiling using screw holes or the like provided in the power supply unit. In this case, when replacing the LED downlight lighting device for maintenance, etc., the lighting unit can be removed from inside the car, but in order to remove the power supply unit which is screwed to the underside of the ceiling, it was necessary to go above the car and remove the power supply unit. Generally, the product lifespan of the lighting unit and power supply unit that use LEDs is the same, so replacement is recommended. Therefore, when replacing an LED downlight lighting device, it is necessary to replace both the lighting unit and the power supply unit. However, this requires work to be done both inside the car and above the car, which creates the problem of poor maintenance efficiency. [Prior art documents] [Patent documents]

[0049] Next, a method for attaching the illumination unit 9 and the power supply unit 109 in another embodiment will be described with reference to FIG.

[0050] For example, when replacing an existing elevator lighting device 108, the lighting unit 9 and power supply unit 100 are pulled out into the elevator car 1. At this time, the lighting unit 9 and 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 source is connected to the power supply unit 100 at a length that allows it to be pulled out 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 cables.

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

[0052] Thereafter, the power supply unit 100 is slid on the bracket 111 in the first horizontal direction D1 toward the first bent 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, both formed from an arc-shaped spring material, so that 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 with a single operation by the simple attachment means 128, which does not require the use of tools or the like for screwing.

[0053] (B) Furthermore, in the elevator lighting device 8 according to the above embodiment, the engaging portion 18 of the simple attachment 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 configured as hook-and-loop fasteners such as Velcro (registered trademark) or Magic Tape (registered trademark). Naturally, the same action and effect can be obtained with such a configuration.

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

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

[0056] (E) Furthermore, in the elevator lighting device 8 according to the above embodiment, the bracket 11 is provided with a cover 12, and the cover 12 has a positioning function that indicates the installation position of the power supply unit 10. However, the present invention is not limited to such a configuration.

The engaging portion 18 functions as the simple mounting means 228, which will be described later. The power supply unit 200 can be inserted through a hole 513 opened in the ceiling panel 51 and can be moved in and out of the elevator car 1 through the hole 513.

[0063] Next, a method for mounting the lighting unit 9 and the power supply unit 200 will be described with reference to FIGS.

[0064] For example, when replacing an existing elevator lighting device 208, the lighting unit 9 and power supply unit 200 are pulled out into the elevator car 1. At this time, the lighting unit 9 and 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 source is connected to the power supply unit 200 at a length that allows it to be pulled out 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 hole 513 opened in ceiling panel 51, and then power supply unit 200 is passed through hole 513 and inserted into the back surface of ceiling panel 51. A worker replacing elevator lighting device 208 inserts his / her arm through hole 513 and inserts insertion portion 29 of power supply unit 200 into notch 1122 of bracket 112. Notch 1122 and insertion portion 29 provide a positioning function that indicates the installation position of power supply unit 200 and a function to prevent rattling when power supply unit 200 is assembled into ceiling panel 51 at the factory and shipped and transported.

[0066] Thereafter, 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 portion 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 with a single operation by the simple attachment means 228, which does not require screws or the like using tools or the like.

[0067] (F) Furthermore, 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 this 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 attached directly to the ceiling panel 51 without the bracket 11.

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

[0069] (H) Furthermore, the mounting portion 17 for fixing the lighting unit 9 is made of a leaf spring bent in a V-shape in a direction away from the lighting main 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.

[0070] (J) For example, the order of execution of each step, such as the operations, procedures, steps, and stages, in the methods and apparatuses shown in the claims, specifications, and drawings, can be implemented in any order, as long as the result of a previous step is not used in a subsequent step. For example, even if a description is made using "first," "next," etc. for convenience, this does not mean that the steps must be executed in that order. [Explanation of symbols]
