When light travels from one medium to the smooth interface of another, some of the light is reflected from the interface and some of the light is refracted from the interface in another medium.The law of reflection is that the incident Angle of light is equal to the reflected Angle, and the reflected light and the incident light are on both sides of the normal line in the same plane.Refracted light is in accordance with the law of refraction: the refracted light is located in the plane of incident light and normal line, the refracted light and incident light are on both sides of the normal line, and the sinusoidal ratio of incident Angle and refractive Angle is constant.Both the refraction law and the reflection law are the basis of geometrical optics. They not only lay the foundation for theoretical research, but also for the development of optical technology, especially diffusion plate, and the design of optical products.

PC diffusion plate is on the basis of the ordinary PC monolayer plate after the special craft processing products, a new type of optical material is to realize the uniform surface light, PC diffusion plate effect is good or bad, is closely related to the use of diffusion particles content and composition, the diffusion of particle content is less, light transmittance, the higher the degree of fog, the lower the diffuser can be plain, translucent color, spread the content of the particle, the more light transmittance, the lower the degree of fog, the higher the diffuser plate generally like white, not transparent color, thus it can be seen that diffusion plate light transmittance and haze is inversely proportional to, they do not have it all,Through 20 years of continuous research, development and innovation of diffusion masterbatch by Korean ISO, the best effect of diffusion uniformity can be achieved by adjusting the surface structure of diffusion plate and diffusion masterbatch.

USES: LED and fluorescent lamp, panel lamp, advertising lamp box, bulletin board, outdoor billboard, stage special effect, LED electronic display, natural lighting ceiling lamp.
