Most of them use fluorescent lamps and LED lamps. Fluorescent lamps are a common elevator lighting device with the advantages of high luminous efficiency, long life, energy saving and environmental protection. They can control the switching time and brightness through timers and photoelectric sensors to ensure proper lighting effects; LED lamps are a new type of elevator lighting device with the characteristics of high brightness, low energy consumption, long life, shock resistance, and corrosion resistance.

The diffuser is located below the light guide plate. The utility model can save energy and provide relatively soft and uniform light in the elevator.

[0004] The above-mentioned prior art solutions have the following defects: the above-mentioned lighting lamp can achieve soft and uniform light, but the dust and mosquito corpses accumulated on the inside of the elevator lighting lamp after long-term use will accumulate above the diffuser, making it difficult for cleaning staff to clean, thus affecting the lighting effect. Therefore, we propose an elevator lighting device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide an elevator lighting device to solve the problem in the above background technology that dust and dead mosquitoes accumulated on the inner side of the elevator lighting lamp after long-term use will accumulate above the diffusion plate, making it difficult for cleaning staff to clean, thereby affecting the lighting effect.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator lighting device, comprising a box-type elevator top plate, a lighting lamp body is fixedly installed below the box-type elevator top plate, a lighting lamp fixing plate is arranged at the upper end of the box-type elevator top plate, a heat dissipation outer frame is fixedly installed below the lighting lamp fixing plate, a protrusion is arranged on one side of the lower end of the heat dissipation outer frame, slide grooves are symmetrically arranged on both sides of the lighting lamp fixing plate, an outer sliding mechanism is slidably installed at one end of the slide groove, a cleaning mechanism is installed inside the inner wall of one side of the lower end of the lighting lamp fixing plate, a dust outlet groove sealing mechanism is installed inside the inner wall of the other side of the lower end of the lighting lamp fixing plate, and a diffusion plate is arranged at the middle position of the lower end of the lighting lamp body.

[0007] Preferably, the protrusion is a triangular structure, a first human infrared sensor is arranged at the middle position of the lower end of the protrusion, and a second human infrared sensor is arranged at the middle position of the other side of the lighting fixture plate.

[0008] Preferably, a first magnetic block is arranged inside the upper end of the outer sliding mechanism, an outer sliding mechanism handle is arranged at the lower end of the outer sliding mechanism, a limiting slider is arranged at the upper end of the outer sliding mechanism, and the limiting slider is slidably connected to the outer sliding mechanism.

[0009] Preferably, the cleaning mechanism is located above the outer sliding mechanism, and the cleaning mechanism includes a cleaning mechanism sliding base, a fixed seat, a second magnetic block and a cleaning brush. The cleaning mechanism sliding base is located on both sides of the lower end of the cleaning mechanism, and the fixed seat is located above the two cleaning mechanism sliding bases, and the cleaning mechanism sliding base is fixedly connected to the fixed seat.

[0010] Preferably, a second magnetic block is arranged inside the sliding base of the cleaning mechanism, and the first magnetic block corresponds to the second magnetic block.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. During cleaning, the cleaning staff only needs to grasp the outer sliding mechanism handle of the outer sliding mechanism to let the outer sliding mechanism slide with the outer sliding mechanism. At the same time, the first magnetic block in the outer sliding mechanism is magnetically connected with the second magnetic block in the cleaning mechanism. When the outer sliding mechanism slides, it drives the cleaning mechanism to slide synchronously. The cleaning brush at the lower end of the middle position of the cleaning mechanism pushes the dust and mosquito corpses on the upper surfaces of the diffusion plate and the lighting fixture plate, and moves them toward the dust outlet slot. When the fixing seat moves to one side of the dust outlet slot sealing block, when the pushing force is greater than the elastic force of the compression spring, the dust outlet slot sealing block can be pushed to one side, thereby pushing the dust and mosquito corpses out of the dust outlet slot, solving the problem that the dust and mosquito corpses accumulated on the inner side of the elevator lighting lamp after long-term use will accumulate above the diffusion plate, which is difficult for cleaning staff to clean, thereby affecting the lighting effect.

[0015] 2. When the elevator door is opened and the passenger enters the sensing range of the first human infrared sensor, the inclined first human infrared sensor on the protrusion senses the human infrared light outside the elevator door and outputs a high level, thereby turning on the power of the lighting lamp body. When the passenger enters the sensing range of the second human infrared sensor, the second human infrared sensor outputs a high level, thereby continuously turning on the power of the lighting lamp body. When the human body leaves the sensing range of the first human infrared sensor and the second human infrared sensor, the first human infrared sensor and the second human infrared sensor will automatically delay turning off the high level, thereby realizing that the lights in the compartment elevator are in the off state when no one is using them, thereby saving the power of the lighting lamp body in the elevator.

When the fixing seat 18 moves to one side of the dust outlet groove sealing block 22, when the pushing force is greater than the elastic force of the compression spring 21, the dust outlet groove sealing block 22 can be pushed to one side, thereby pushing the dust and mosquito corpses out of the dust outlet groove 6.

A first human infrared sensor 4 is arranged at the middle position of the lower end of the protrusion 3, and a second human infrared sensor 5 is arranged at the middle position of the other side of the lighting fixture plate 10.

The dust outlet groove sealing mechanism 14 includes a compression spring 21 and a dust outlet groove sealing block 22. The dust outlet groove sealing block 22 is located above the dust outlet groove 6, and the dust outlet groove sealing block 22 is sealed and connected to the dust outlet groove 6.

[0031] Working principle: When the elevator door is opened, when the passenger enters the sensing range of the first human infrared sensor 4, the inclined first human infrared sensor 4 on the protrusion 3 senses the human infrared light outside the elevator door and outputs a high level, thereby turning on the power of the lighting lamp body 1. When the passenger enters the sensing range of the second human infrared sensor 5, the second human infrared sensor 5 will output a high level, thereby continuously turning on the power of the lighting lamp body 1. When the human body leaves the sensing range of the first human infrared sensor 4 and the second human infrared sensor 5, the first human infrared sensor 4 and the second human infrared sensor 5 will automatically delay turning off the high level, thereby realizing that the lights in the cabin elevator are in the off state when no one is using them, thereby saving the power of the lighting lamp body 1 in the elevator. When cleaning, the cleaning staff only needs to Grasp the outer sliding mechanism handle 15 of the outer sliding mechanism 8, let the outer sliding mechanism 8 slide with the outer sliding mechanism 8, and at the same time, the first magnetic block 16 in the outer sliding mechanism 8 is magnetically connected with the second magnetic block 19 in the cleaning mechanism 13. When the outer sliding mechanism 8 slides, it drives the cleaning mechanism 13 to slide synchronously. The cleaning brush 23 at the lower end of the middle position of the cleaning mechanism 13 pushes the dust and mosquito corpses on the upper surfaces of the diffusion plate 2 and the lighting lamp fixing plate 10, and moves them toward the dust outlet groove 6. When the fixing seat 18 moves to one side of the dust outlet groove sealing block 22, when the pushing force is greater than the elastic force of the compression spring 21, the dust outlet groove sealing block 22 can be pushed to one side, thereby pushing the dust and mosquito corpses out of the dust outlet groove 6. After the cleaning mechanism 13 is removed, the elastic force of the compression spring 21 prompts the dust outlet groove sealing block 22 to reset.
