网投平台I. Overview: light diffusion plate is light through the diffusion layer PMMA / PC / PET and other plastic substrate, the refractive index of dissimilarity meet its medium (diffusion particles) occurs when multi-angle, multidirectional refraction, reflection and scattering phenomena, so as to achieve a light diffusion effect for display lighting component provides a uniform surface light source.

Second, the theoretical basis: when the light from one medium onto another medium smooth interface, part of the light reflected by the interface, the other part of the light refracted through the interface in another medium. The angle of incidence equals the angle of reflection of light and the reflected light of the incident light side in the same plane as the Sino-   French line, which is the law of reflection. The refracted light is in line with the law of refraction: the refraction of light is located in the plane normal to the incident and refracted light and incident light on both sides of the normal and the incident angle and the ratio of the sine of the angle of refraction is a constant. The laws of refraction and reflection are the basis of geometrical optics, they are not only in theory, but also for the development and design of optical products optical technology laid the foundation.

Third, the light diffusion plate Background: With the rapid development of LED interiorlighting, lighting design how to improve, improve lighting effects, without reducing thelamp brightness of the premise, the LED light source into a dazzling soft, healthy light sources, LED lighting products is currently R & D staff has been concerned,in this context, the light diffusion plate came into being. The birth of the light diffusionplate, is to replace the traditional frosted glass shade of a trend, itwill act as a "see the light but not light bead" effect.

网投平台Fourth, the light diffusion plate features:

网投平台1, the conventional diffusion plate is in material means matte surface treatment, low haze andlight absorption rate, low light transmittance, can only reach about 50%.The new diffusion plate, according to the characteristics of the market lamps, especially LED panel lights and downlights features to opticalgrade PMMA / PC plastic sheet to the substrate, the use of advanced optical design and diffusion of materials, through the scientific formula processing, so light between chemical particles andresin continued refraction, reflection and scattering, thereby adjusting the scientific direction of light propagation, so that the diffusion plate products 

with high light transmittance and good light diffusion effect.

2, silky texture frosted surface, the visual effect of high-   grade appearance, abrasion resistance, scratch resistance, UV stable performance, good weather resistance, in which the diffusion plate PMMA long-term use at 80 degrees Celsius.

3, the diffusion plate processing convenient, bending, thermoplastic, had no effect on material properties.

V. Application areas

1, the diffusion plate is suitable for direct type light source, LED lighting, such as downlights, grille, high-grade aluminum lamp.

网投平台2, the diffusion plate for side light LED lighting, such as flat lights, advertising light boxes, professional film viewer, usually with the use of the light guide plate.
