Panel lamp lining pad of thin shell and convex curved surface arch-shaped structure

Abstract

The invention belongs to the field of LED panel lamps, and particularly relates to a panel lamp lining pad of a thin shell and convex curved surface arch-shaped structure. The panel lamp lining pad comprises a lining pad body. A plurality of elastic protrusions are evenly distributed on the plate face of the lining pad body. The heights of all the elastic protrusions on the plate face of the lining pad body are equal. The panel lamp lining pad has the beneficial effects that a rear cover plate press a panel lamp in an abutting mode structurally, the elastic protrusions on the lining pad body can tightly press a light guiding plate into a profile frame structure in an abutting mode, thus the central lines of both a light emitting strip and the light guiding plate are always kept consistentwithout dislocation, light brightness is uniform, light leakage of the edge is avoided, and the light leakage problem caused by dislocation is solved accordingly; and the elastic protrusions are evenly distributed and arranged, thus force bearing of all the elastic protrusions can be even, all the elastic protrusions press a reflection film in an abutting mode, microscopic arching or rising and falling of the reflection film is avoided, accordingly the problem of large-area water ripples is solved, and it is ensured that the light surface is uniform and attractive.

Description

technical field [0001] The invention belongs to the field of LED flat lamps, and in particular relates to a flat lamp liner with a thin shell convex curved surface and an arched structure. Background technique [0002] The panel light pad is an important component of the panel light. It is located between the back cover of the panel light and the reflective film. Its function is to tightly adhere the reflective film to the rear surface of the light guide plate. The light emitted by the side-emitting light source enters the light from the side of the light guide plate and enters the light guide plate after being incident. The light in the light guide plate undergoes multiple light changes such as reflection, refraction, and diffuse reflection, especially in the reflection of the reflective film. Under the effects of , diffuse reflection, etc., the light becomes a straight light relative to the plane of the flat panel light, and emits from the front of the light guide plate, t...

Problems solved by technology

[0005] In the LED flat panel light of the present invention, the flat panel light presses the gasket body through the back cover structurally, and the elastic protrusion on the gasket body can press the light guide plate tightly against the structure of the profile frame, so that The light strip and the center line of the light guide plate are always consistent without misalignment, the brightness is uniform, and there is no light leakage at the edge, thus solving the problem of light leakage caused by misalignment
