Problems solved by technology

[0003] The car with this structure can provide better lighting effects and a better top appearance, but the biggest disadvantage is that the ceiling cannot be fixed to the car wall for easy disassembly and assembly, so there will be gaps between the ceiling and the car wall. A certain gap, the gap will produce edge light leakage under the light source, and the appearance effect is poor

Embodiment 1

[0018] A non-light leakage suspended ceiling, comprising a ceiling frame 2 installed on the top of a car, a lighting device 4 is installed above the ceiling frame 2, and a light blocking groove 6 parallel to the ceiling frame 2 is provided on the wall 1 of the car. The outer ring is provided with an opaque brush structure 5 extending outward. The length of the brush structure 5 is not less than the distance between the edge of the ceiling frame 2 and the car wall 1 of the car. The brush structure 5 is composed of several soft materials, one end is fixed to the ceiling frame 2 and the other end points toward the outer ring of the ceiling frame 2. The movable end of the brush structure 5 extends into the light blocking groove 6. The density of the brush structure 5 is 1 to 1.4.

[0019] The ceiling further includes a light homogenizing plate 3 arranged on the inner circle of the ceiling frame 2, and the lighting device 4 is arranged directly above the light homogenizing plate 3.

Abstract

A light-leakage-free ceiling comprises a ceiling frame installed at the top of a lift car, an illumination device is installed on the upper portion of the ceiling frame, an opaque hairbrush structure extending outwards is arranged on the outer circle of the ceiling frame, and the length of the hairbrush structure is not smaller than the distance between the edge of the ceiling frame and the wall of the lift car. Light leakage at the edge of the ceiling is effectively blocked without affecting installation of the ceiling, the appearance effect is good, the structure is simple, and the modification cost is low.

Description

Technical field [0001] The invention relates to an elevator ceiling, in particular to a ceiling without light leakage. Background technique [0002] The traditional car is made of metal. When the car door is closed, light cannot enter the car. Therefore, the traditional car is equipped with a light source. The best installation position of the light source is the top of the car. In order to ensure the appearance effect, a suspended ceiling is installed on the top of the car to cover some mechanical devices on the top of the car. [0003] The car of this structure can provide better lighting effects and better top appearance, but the biggest disadvantage is that the ceiling is often easy to disassemble and cannot be fixed to the car wall, so there will be a gap between the ceiling and the car wall. A certain gap, the gap will cause edge light leakage under the illumination of the light source, and the appearance effect is poor. Summary of the invention [0004] In order to solve th...
