SINHAI opal color solid plastic led pc polycarbonate light diffuser sheets
The light diffusion material refers to a material that enables light to effectively scatter light, which converts a point source into a wire source or a wire source to surface light source, and can be used as a light source material to a cold light, guide Light plates, backlight devices, and liquid crystal displays and other devices. This is because the light diffusing agent in the light diffusion material is uniformly distributed. When the point-shaped light source of the LED passes the light diffusion material, many refractive, reflective, scattering, etc., which encounters different refractive indices, etc. The light is uniformly transmitted by the material and does not expose the lamp beads to achieve uniform conversion from the point source to the surface light source to obtain an effect of optical diffusion.
