Acrylic diffusion plate processing function is very good, no tube cutting or injection therapy is very affordable. All the colors of acrylic plates are very good patterns that have appeared in our careers in recent years. Acrylic panels are non-toxic and environmentally friendly, which is his own appreciation. Acrylic sheet itself is a big point and gloss, and it is very convenient to maintain. Many artistic acrylic sheets have added a beauty to our career. The specific gravity of the acrylic diffuser is about 1.19. This depends on whether it is polymerized or added. For example, the diffusing agent will be less than the original specific gravity, if the higher refractive index material will be greater than the original specific gravity, because the diffusing agent is generally lower than the specific gravity produced by the acrylic material, add acrylic Naturally, the original proportion will be diluted and lightened.
Acrylic diffusion plate uses chemical or physical means to use the physical imagination of refraction, reflection and scattering when light encounters two media with different refractive indexes during its course. By adding inorganic or organic light diffusion to the PMMA base material Or through the array of micro-features on the surface of the substrate. The light is artificially adjusted to cause the light to be refracted, reflected, and scattered in different directions, thereby changing the path of light and achieving full dispersion of the incident light to produce optical diffusion. effect.
The background of the manufacture of acrylic diffuser is that in the process of LED lighting being gradually accepted by the market, the problem of LED lighting lamp mask has been plagued by lamp manufacturers, not only has a high light transmittance, but also achieves considerable results. The light diffusion speed is fast and the light source is hidden. Good performance, it is also possible to improve the effectiveness of the lamp, turning the dazzling light source of LED into a soft sound source; this is the direction currently being studied by the personnel. In the beginning, the glass was used to make lampshades, but the glass was fragile and the light diffusion effect was not so good, and it was difficult to meet the lighting requirements. Then it gradually developed to use resin instead of glass, but if only transparent resin is used for the lampshade, the light transmittance is high, but the basic energy can reach more than 90%, but the light diffusion effect is not ideal, and the concealment of the light source is poor.
