Embodiment Construction

[0020] The technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in an embodiment of a light diffusion module suitable for a light box of the present invention.

[0021] An embodiment of a light diffusion module suitable for a light box of the present invention, such as Figure 1 to Figure 5 As shown, the light diffusion module consists of a substrate 1, a plurality of light inlets 2 uniformly arranged in an array on one side of the substrate 1, a spherical structure 3 with the bottom of the light inlet 2 recessed to the other side, and the other side of the substrate 1. The bumps 4 on the raised substrate are formed in one piece.

[0022] The top surface of the bump 4 on the substrate is flat, and the top surface of the bump 4 on the substrate is provided with astigmatism lines 5 . The light diffusion module can use (but not limited to) transparent polymer materials (such as:...

Abstract

The invention relates to a light diffusion module suitable for a lamp box. The light diffusion module is integrally composed of a base plate, multiple light inlets evenly arranged on one side of the base plate in an array, spherical surface structures recessed from the bottoms of the light inlets to the other sides, and convex blocks protruding on the other side of the base plate. The top faces ofthe convex blocks on the base plate are planes, and light diffusion grains are arranged on the top faces of the convex blocks on the base plate. It is known through the technical characteristics thatno obvious dark lines exist on the peripheries of spliced light diffusion modules, and shadowless splicing can be achieved. Meanwhile, after light emitted by a light source is shaped by the recessedspherical surface structures and light intensity distribution is adjusted, light diffused evenly is formed on the top faces of the convex blocks on the base plate. The light diffusion module has the advantages of being simple in structure, high in light transmitting efficiency, low in manufacturing cost and the like.

Description

technical field [0001] The invention relates to the field of light boxes, in particular to a light diffusion module suitable for light boxes. Background technique [0002] In real life, light diffusion modules are widely used in backlights, such as: backlights for TFT-LCD (liquid crystal display), light boxes, lighting fixtures and other equipment. The light diffusion module has different requirements in different equipment applications, and its structure is also very different. For example, the light diffusion part in (liquid crystal display screen), which is composed of high-tech materials such as astigmatism sheet, reflective sheet, and enhancement sheet, has high requirements on the technical indicators of light diffusion, including haze value, light transmittance, and refractive index. , particle size, decomposition temperature, bulk density, etc., so that the dazzling incident light becomes a uniform and soft light that is friendly to the human eye. For the light dif...
