Description

Technical Field

[0001] The utility model belongs to the technical field of elevator ceilings, and in particular relates to a light box structure used for elevator ceilings. Background Art

[0002] At present, in order to meet the aesthetic and lighting requirements, the elevator car will install a decorative ceiling on the top of the car. The ceiling plays an important decorative role in elevator decoration. Its main functions include beautifying the top space inside the elevator, hiding wiring and equipment, etc. Existing elevator cars achieve lighting functions by arranging lighting tools such as light strips and light tubes on the ceiling or under the car top. When a lamp fails and needs to be replaced, it is extremely inconvenient to replace the lamp because it is difficult to dismantle the ceiling in the car.

[0003] The existing solution for replacing lamps is: after placing the elevator in a suitable position, cut off the elevator power supply and confirm that all power supplies are disconnected, use auxiliary tools such as ladders to reach the top of the elevator, remove the fixing screws or other connecting parts of the ceiling and the car bottom, and replace the lamps on the ceiling.

[0004] The disadvantage is that replacing the lamps on the ceiling is too complicated and requires workers to climb onto the top of the car to perform the operation, which poses a safety hazard. Utility Model Content
