Specifically, when face ring and back lid fixed connection, face ring inner wall and back lid lateral wall pass through buckle subassembly cooperation, and the spring assembly when face ring spring buckle and back lid spacing groove department pass through the time of inserting simultaneously, the space that the face ring inner wall encloses is the accommodation space, with diffuser plate 21, light guide plate 22 and the reflection of light paper 23 in the light subassembly 2 stack in proper order in accommodation space 13.

When the buckle is arranged on the inner side of the inner wall of the face ring, the setting height of the buckle on the inner side of the inner wall of the face ring is higher than that of the installed light guide assembly, so that the damage to the light guide assembly when the face ring and the rear cover are installed can be prevented.

The diffusion plate is a diffusion layer of PC/PMMA/PS base material, when encountering medium (diffusion particles) with different refractive indexes, the diffusion plate can generate multi-angle and multi-direction refraction, reflection and scattering phenomena, thereby achieving the light diffusion effect and providing a uniform surface light source for the display lighting assembly. The diffusion plate has the main function of uniformly guiding out the light of the light guide plate, so that the light distribution is more uniform. When light rays are emitted to the diffusion points, reflected light can diffuse towards all angles and then is emitted from the front surface of the light guide plate, and the light guide plate uniformly emits light by utilizing various diffusion points with different densities and sizes, so that the brightness of the light guide plate is improved, and the effect of blurring lattice points can be achieved.

The light guide plate is a plate with smooth surface formed by pressing propylene by injection molding, or a ready-made acrylic plate with light transmittance reaching more than 90%; and then printing diffusion points on the bottom surface of the light guide plate in a screen printing mode by using a material with high reflection and light absorption, and fully reflecting light overflowing from the bottom surface back into the light guide plate by using the reflective paper to improve the use efficiency of light and the brightness of the front surface. The light guide plate is used for refracting light rays parallel to the direction of the light transmission plate into the direction perpendicular to the direction of the light transmission plate, and the light rays refracted to the back of the panel light by the light guide plate are reflected by the reflective paper.

The reflecting paper is an optical film, which is used for fully reflecting the overflowed light under the light guide plate, so that the light emitted by the LED is fully utilized, the reflecting paper with the reflectivity close to 100% is selected as much as possible, the light utilization is maximized, and the output brightness of the LED flat lamp, generally RW250, is improved.
