Plastic Diffuser Strip

Plastic diffuser strip specification

Product Name: plastic diffuser strip

Product color: milky white 

Product light transmittance: 70% – 90% (light transmittance can be adjusted as needed)

Product thickness: 0.8mm~3mm

Material:Transparent / light diffusion / Matte surface

The light diffusion is made of PC / PMMA and other raw materials. When light passes through a medium (diffusion particles) with different refractive index, it will refract, reflect and scatter in multiple angles and directions, so as to achieve the light diffusion effect and provide a uniform area light source for the display lighting components.

Background of light diffusion plate: in the process of LED lighting being gradually accepted by the market, the problem of lampshade has been perplexing lamp manufacturers. It is necessary to not only have high light transmittance as the premise, but also have considerable light diffusivity and good light source concealment. At first, the glass was used to produce lampshade. The problem of glass is fragile, and the light diffusion effect is not very good, so it is difficult to meet the lighting requirements and use it immediately. Later, it gradually developed to use PC to replace glass. If only Transparent PMMA is used as the lampshade, although the light transmittance is very high and can basically reach more than 90%, the light scattering effect is not ideal and the concealment performance of the light source is poor.

Theoretical basis: when light is emitted from one medium to the smooth interface of another medium, some light is reflected by the interface, and the other light is refracted in another medium through the interface. The reflection law is that the incident angle of light is equal to the reflection angle, and the reflected light and the incident light are on both sides of the normal in the same plane. The refracted light conforms to the refraction law: the refracted light is located in the plane between the incident light and the normal, the refracted light and the incident light are on both sides of the normal, and the sine ratio of the incident angle and the refraction angle is a constant. Refraction law and reflection law are the basis of geometric optics. They not only lay a foundation for theoretical research, but also for the development of optical technology and the design of optical products.

The advantage of the light diffusion plate is that under the premise of ensuring high light transmittance, the light diffusivity and haze of the product are increased. Through the action of the diffusion plate, a uniform luminous surface is formed on the whole board without forming a dark area, and a residual image is formed on the picture, which makes the picture more realistic and achieves the visual effect of glittering and translucent.
