Diffusion plate and light guide plate
During the development of LED energy-saving lighting, some of the problems with LED lamps often plague manufacturers. To make LED lighting lamps, not only high light transmittance is required as a prerequisite, but also high-quality light diffusivity and good To solve the problem, to improve the effect of LED lamps is to turn the dazzling LED light source into a soft and healthy light source. This is the main direction currently being researched by researchers.
The diffuser plate is mainly to open up the luminous flux and make the light evenly distributed. The main principle is to penetrate through other media to cause the phenomenon of scattering. The diffuser plate has a unique advantage that there are three physical phenomena. Due to the frosted surface of the diffuser, the visual effect is high-grade and beautiful, abrasion resistance, scratch resistance is stable, UV resistance, weather resistance, and can be used for a long time below 80 degrees Celsius, so it is popular with the public.
The light guide plate is an acrylic material in optical materials. It is a high-factor material with extremely high reflectivity and non-light absorption. The optical grade acrylic plate is used to absorb the light emitted by the lamp and is carried out on the surface of the optical grade plate. Stay, when the light is reflected to each light guide point, the reflected light will diffuse in all directions, and then destroy the reflection conditions. After multiple layers of reflection, various dense, uniformly shaped points can be formed. The LED light guide plate can emit uniform light, and the reflective sheet is mainly used to put on the bottom surface to improve the efficiency of light use.
