1.  Development history of PMMA diffusion sheet
     The development of light diffuser material has gone through several stages
     1. Add particles with diffusing effect to improve light source shading and obtain cost performance
     2. Improve the diffusion effect, improve the appearance performance, improve the light transmittance
     3. Optimize optical properties, improve UV resistance, improve impact resistance, improve light efficiency, meet light distribution requirements, high temperature resistance, and maintain high light transmittance. On the premise, the haze value of the product is increased, which is suitable for use in close-range irradiation environments.

Considerations for LED lighting:
1. The best light mixing performance: high light softness
2. High light transmission performance: reduce energy consumption and improve the illumination of lamps
3. Small influence on the light source: maintain the consistency of the color rendering of the light source and reduce the color shift
4. Minimize light interference: keep the design of the original light distribution curve of the lamps

 
3.  Microstructured light diffuser
The microstructure light diffusing plate is arranged in an array of micro-feature structures on its surface, so that the light is refracted in different directions when passing through, changing the light's travel route, realizing the sufficient dispersion of the incident light, and achieving a softer and more uniform illumination effect. Common micro-specialty structures include the following: [2]
A, V-groove array
B, U-shaped convex groove array
C, pyramid array
D, circular array
E, microlens array
The microstructure light diffusion plate has high transmittance. By changing the shape and different arrangement of the microstructure, the diffusion angle, the space and energy distribution of the light field can be adjusted, and the effect on the uniformity and light transmittance of the light diffusion plate can be realized. Therefore, it has attracted the attention of researchers, and it is generally not suitable for lighting when used in backlight modules.
3, diffractive diffuser
Diffractive diffuser is a kind of light mixing function. It does not really diffuse light. It is generally used for imaging optics or local lighting fixtures.
According to the material of the light diffusing board substrate, the light diffusing board includes the following categories:
PMMA diffusion plate: with PMMA (polymethyl methacrylate, alias acrylic, plexiglass) as the base material;
PS diffuser plate: based on PS (polystyrene);
PC diffuser plate: based on (polycarbonate);
PP diffuser plate: based on (polypropylene)
MMA diffuser: based on MMA (polymethacrylic acid)
