Description

Technical Field

[0001] The utility model belongs to the technical field of elevator lighting, and particularly relates to a lighting device for an elevator. Background Art

[0002] A car is a box-shaped space in an elevator for carrying and transporting people and materials. The car is generally composed of main components such as a car bottom, car walls, a car top, and a car door. It is a car body component of the elevator for carrying passengers, goods, and other loads. In order to ensure the lighting function inside the car, the car needs to be equipped with a lighting device. When the existing elevator lighting equipment is actually used, it will generate a certain amount of heat. If these heats are not diffused in time, they are likely to accumulate around the LED light strip, resulting in the LED light strip working in an overheated environment for a long time, and ultimately causing the LED light strip to be damaged frequently.

[0003] The Chinese utility model patent with the publication number CN212961480U discloses a lighting device for an elevator car. By arranging a temperature-sensing control device in the installation cavity, when a large amount of heat accumulates during the long-term operation of the LED light strip in the installation cavity, the temperature-sensing control device will automatically turn on multiple groups of small cooling fans to cool the installation cavity, avoiding the LED light strip working in an overheated environment for a long time and improving the service life of the LED light strip. The setting of the dust-proof net can avoid the entry of external dust into the installation cavity while not hindering the normal heat dissipation of the heat dissipation holes. By arranging engraved patterns on the lower side wall of the transparent lamp cover plate, the aesthetics of the transparent lamp cover plate is increased. However, when the device is in use, when the lamp strip is damaged, maintenance personnel need to disassemble the corresponding LED lamp strip in the installation cavity. During this process, it is necessary to repeatedly screw the screws to disassemble the lamp tube, so that the installation and disassembly process of the lighting lamp tube is relatively cumbersome.

In this way, rollers 140 and ropes 150 can be arranged on both the left and right sides of the fixing plate 120. In this way, one motor 130 can control the rotation of the two rollers 140, so that the two ropes 150 can respectively pull up or lower the fixed shafts 220 on both sides of the mounting frame 310, and thus the position of the mounting frame 310 can be changed smoothly. When the motor 130 contracts the rope 150, it can drive the mounting frame 310 into the internal of the through groove 110. When the motor 130 relaxes the rope 150, under the gravity of the mounting frame 310, it can slowly lower the height. In order to control the positive and reverse rotation of the motor 130, control buttons are arranged inside the box body to control the positive and reverse rotation of the motor 130. At the same time, a pressure sensor can also be arranged, so that the motor 130 can be stopped at a suitable position, and thus the mounting frame 310 can be stopped from moving.
