Diffusion Applications
A. Diffuser plate(DP) |
A. Diffuser plate(DP): Down Light / Panel Light / Ceiling lighting, etc .. Diffusion applications
The main function of the diffusion plate so that the light transmitted through the optical diffusion composite material, the surface light source to produce a uniform distribution of luminance, and the brightness-enhancing effect of reach.

C. Light diffusing powder
Particles suitable for optical demand related applications, which can provide excellent light diffusion effect and high brightness of the show; also has good heat resistance and dispersion.
Another to add to the resin or plastic in the dispersion with good compatibility, there are light show good results and will not affect the color vividness, and also has a slippery surface feel of comfort。
