Acrylic diffuser, also known as PMMA diffuser, is a material with light diffusing properties in the PMMA (polymethyl methacrylate, alias acrylic, acrylic, plexiglass) sheet type, is PS (polystyrene) ), PC (polycarbonate), PP (polypropylene) and other material diffuser plate categories, with high haze, high light transmittance, high diffusivity and other optical characteristics of plastic plates, can effectively point or The linear light source is transformed into a soft and uniform surface light source. On the premise of achieving good light transmittance, it also has good light source lattice shielding properties. It is an ideal optical material to solve the secondary light distribution of LED lighting products. It is LED lighting. The product is the best light diffusing material. Principle of acrylic diffuser The diffuser uses chemical or physical means to use the physical imagination of refraction, reflection and scattering when light encounters two media with different refractive indices on the way. By adding inorganic or organic light diffusing agents to the base of PMMA substrate , or artificially adjust the light through the array arrangement of the micro-features on the surface of the substrate, so that the light is refracted, reflected, and scattered in different directions, thereby changing the light's travel route, and achieving sufficient dispersion of the incident light to produce the effect of optical diffusion. . Application of acrylic diffuser plate Acrylic diffusers are widely used in the field of lighting due to their obvious comprehensive advantages in performance, mainly reflected in LED flat light panels, LED downlights, grille lights, ceiling light masks, advertising light boxes, signs and other products.
