The characteristic of the diffuser is that it causes great interference to the light. No matter how many degrees the light distribution curve of the original design is, as long as the light passes through the diffuser, it will make the beam angle change to 160 ~ 176 degrees. Therefore, from the side view, there is a layer of fog on the surface of the lamp. From this point, it can be proved that the beam angle is as large as 160 ~ 176 degrees. The larger the beam angle is, the lower the illumination is. Some of them will produce filter, so that some wavelengths will be changed It can't penetrate and cause color deviation. For example, if the surface is processed by light interference again (such as sanding and embossing), the light transmittance is even lower due to the natural phenomenon of geometric optics. Therefore, the substrate used to make the diffusion plate should be selected. The lower the refractive index, the better, the lower the light interference.

Light diffusion plate is widely used in liquid crystal display, LED lighting and imaging display system. Its main function is to make the incident light fully scatter and achieve a softer and more uniform illumination effect.




A. Application of diffusion plate in liquid crystal display


The direct down backlight system used in LCD TV has good performance such as heat resistance, dimensional stability, mechanical strength, fire resistance, high light transmittance, excellent shielding and durability, which makes the light diffusion effect reach a good state. It is most suitable for direct down backlight unit




Product features


Light source diffusion: suitable for direct backlight module, with high brightness and high diffusion, which can improve the diffusion effect of uniform distribution of backlight.


Light transmittance: good light transmittance produces high brightness.


Dimensional stability: the smallest water absorption, can maintain good dimensional stability in humid environment, and can be used normally in the temperature range of - 40 ℃ ~ 125 ℃.


Antistatic: it has good surface antistatic performance to prevent dust adsorption.


B. Application of light diffusion plate in lighting





Requirements for light diffusers for LED lighting:



1. Good diffusion performance: high light softness;


2. High transparency: reduce energy consumption and improve the illumination of lamps;


3. Influence on the light source: keep the consistency of the color temperature of the light source.
