Light diffusion module of backlight source

Abstract

The invention relates to a light diffusion module of a backlight source, which comprises a diffuser and a lens integrated block, wherein the diffuser is formed by integrating a diffuser plate and a diffuser side plate. The lens integrated block is composed of a substrate, a plurality of backward-protruding basin-shaped convex blocks with square basin-shaped structures orderly arranged in an arraymanner which are positioned at the rear side of the substrate, and lamp holes which are arranged on the rear side of each basin-shaped convex block and have a basin bottom part which is recessed forwards; a spherical structure is positioned at the bottom of the lamp holes; protective walls are arranged around all the lamp holes and protrude backwards; a stopper is arranged around the substrate andprotrudes from the periphery; first screw hole pillars on the plurality of lens integrated blocks which are arranged at the rear side part and protrudes backwards are integrated into a transparent solid block. The lens integrated blocks are mounted on the rear side of the diffuser; and the substrate is embedded into the space enclosed by the diffuser side plate. The light scattering module can realize shadowless splicing; and the light diffusion module of the backlight source has the advantages of simple structure, convenience in installation, low manufacturing cost, high light transmission efficiency, capability of realizing waterproofing and the like.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a light diffusion module of a backlight source. Background technique [0002] In real life, the application of backlight is extremely extensive, such as: TFT-LCD (liquid crystal display), light box, lighting and other backlight equipment. The uniformity of light is one of the important indicators of the backlight source. Different applications have different requirements. For example, the backlight module in (LCD display) is composed of high-tech materials such as astigmatism sheet, reflective sheet, brightness enhancement sheet and light source. The technical indicators of the backlight source are very demanding. Therefore, the price of the light diffusion member used for TFT-LCD is high. [0003] With the development of the global economy and the continuous advancement of global urbanization and smart cities, the application of light diffusion modules will be more extensive. There...

AI Technical Summary

Problems solved by technology

Since the diffuser plate is installed on the front side of the box, and the light source is installed on the back side of the box, there is a relatively large distance between the light source and the front side, so the direct-type backlight is relatively thick; at the same time, the box is surrounded by an opaque box. After the body wall is spliced, there will be serious shadows between the cabinets, and it is impossible to achieve shadowless splicing
