Light diffusion agent
dex resin will cause a lot of light reflection of the light transmission rate, close to the resin refractive index, the path will reduce the light scattering, transparency decreased less, light source can not be effectively covered.Second, the light diffusion agent is greater than the wavelength of visible light particle. The diameter of the light diffusion agent than the wavelength of visible light (0.4 ~ 0.75um) large, it dispersed in the resin in the sufficient amount of light diffusion agent
