Multilayer integrally-formed anti-dazzle optical diffuser plate

Abstract

The invention relates to a multilayer integrally-formed anti-dazzle optical diffuser plate which comprises an optical diffuser plate body. The multilayer integrally-formed anti-dazzle optical diffuser plate is characterized in that the optical diffuser plate body is composed of light-penetrating optical scattering layers which are obtained through integral co-extrusion and extension and have different optical performances; the top surface of the optical diffuser plate body is a light outlet surface; the light outlet surface is also provided with a light outlet diffusion structure layer which is obtained through integral co-extrusion and extension with the optical diffuser plate body; the bottom surface of the optical diffuser plate body is a light inlet surface; and each light-penetrating optical scattering layer is provided with an optical scattering particle structure. The optical diffuser plate has a multilayer structure and is obtained through integral forming. Simple structure and low production cost are realized. Debugging and manufacture of optical boards which are in different optical grades and have different optical performances by an optical board manufacturer can be greatly facilitated, thereby realizing selection and application by each industry. The multilayer integrally-formed anti-dazzle optical diffuser plate has advantages of uniform and soft illumination, high illumination brightness, small light loss, and high anti-dazzle effect.

Description

technical field [0001] The invention relates to the field of optical plates, in particular to a light diffusion plate. Background technique [0002] LED is a new type of energy-saving light source, which has been widely used in indicator lights, monitors, televisions and lighting in the market. However, LED light sources also have their own shortcomings, such as direct glare and small irradiation angles. In practical applications, in order to overcome the shortcomings of the LED light source itself, a light diffusion plate is usually added at the front of the LED light source to make the light from the LED light source diffused by the light diffusion plate, and the light is soft and uniform, not dazzling, and can avoid glare. For people to apply the required light source. [0003] At present, the existing light diffusion plate mainly has the following two forms: [0004] One is to use a light diffusion plate with a milky white diffuser added to the plate. After the LED li...

AI Technical Summary

Problems solved by technology

This form of light diffusion plate cannot be formed together with the light-transmitting plate forming process, requiring more processes and higher production costs, which reduces the market competitiveness of manufacturers

And it is coated with an anti-glare coating layer, which is also prone to discharge of chemical pollutants and damages the environment.
