LED panel light diffusion plate 
 Shade has been plagued by lighting manufacturers in LED lighting gradually been accepted by the market process 
 Both have a high transmittance to do the premise, while at the same time to do a considerable light diffusion rate and a good light source concealed. Originally made of glass lampshades, but not fragile glass, and light diffusion effect is not very good, very difficult to achieve the lighting requirements. Later evolved to the resin instead of glass, but if only the transparent resin shade, high transmittance, could meet the 90% or more, but the light diffusion effect is not ideal, light concealment. White resin, the light transmission rate is too low, a serious impact on the lighting of the LED lights. 
 Traditional diffusion including laser engraving, add the milky white pigment, surface grinding, and other technical means, but there is light transmission rate is too low, a serious impact on the lighting of the LED lights. 
 The light diffusion plate light diffusion agent ingredient in the production process, the scientific added in the optical-grade PMMA particles. Its core technology is the use of the scientific process dispersants evenly distributed in the plate, when the light sheet, and the diffusion of the particles encounter refraction, reflection, scattering and other optical effects, so that the light efficient, uniform and soft through over the plate, at the same time not to reveal the light source. 
 LED panel lights, derived on the basis of the original LED backlight with the development of the LED, the basic principle is that the LED power light source or line source into surface light source, also known as the LED panel lights, because the whole body bright , uniform and soft light, no glare, fine structure, so the product was released, become recognized by the market. The flat lamp structure including: aluminum frame, light diffusion plate, light guide plate, reflective paper, which the light diffusion plate, the LGP is at the core of the flat-panel lights: light guide plate: the side of the LED light through outlets refraction, reflection to change the light angle of injection, thus the linear light source into surface light source. On the silk screen on the quality of the LED light guide plates, the substrate of the light guide plate, network design and printing inks three directly determines the light guide plate: a network design certain principles of optics, network design, there will be the overall brightness inconsistent local dark areas, color pictures of the cloud feeling. 2, the selection of the plate, the optical properties of the plate - light transmission rate is a very important indicator. But if the blind pursuit of brand board, is also defective, such as popular on the market Mitsubishi board, Chi Mei board, etc., most of their good plates have been manufacturers of Order Well, many markets flowing out of multi-brand board scrap In fact, the light transmittance is not necessarily better than the domestic optical-grade plate. Plate selection of test high transmittance of light effects on Ok. 3, the optical properties of the ink directly affect the absorption of light, refraction and reflection performance. Light diffusion plate: plays to the optical light guide plate injection step further evenly shed to form a uniform surface light source, at the same time plays the role of block outlets. Can not see the network on the diffusion plate installed, the light transmission rate in more than 90%, it is necessary to weigh the unity of the diffusion plate light transmittance and haze of these two contradictory. Market diffusion board material PMMA and PC materials, of course, the grade is more low-end PS diffusion plate. Diffuser plate of different materials with different optical and physical and chemical properties. This point of view of the light transmission rate, the proliferation of acrylic diffuser plate than PC boards have an advantage, so as LED flat light panel is to minimize the optical loss of the ideal material selection. 

 The panel light diffusion plate applications: LED side light panel light performance indicators: 1, material optical grade PMMA imported class;, high transmittance, high haze, light transmission rate up to 92%, haze up to about 93.5% ; 3, the diffusion plate material used in advanced optical design and organic diffusion material, the sheet side of the matte side of the orange peel, and adjust the light propagation direction to improve the optical brightness and diffusion effects. 4, the perfect embodiment of the light source color: color temperature does not drift, the color rendering index does not decline, maintain with LED character; higher brightness in the case of the same light source, effectively reduce the optical loss; 6, excellent weather resistance and heat sex; 7, silky texture of the matte processing, visual effects, more upscale appearance; the texture of orange peel pattern, increased abrasion resistance, scratch resistance stability, more importantly, is to assist the atomization effect.
