The biggest feature of the diffusion plate is that it interferes a lot with the light. No matter how many degrees the light distribution curve of the original design is, as long as the light passes through the diffuser, it will make the beam angle 160~176°, so from the side, the light fixture The surface of the board has a layer of fog and fog. From this point, it can be proved that the beam angle is as large as 160~176°. It is better to prove that the larger the beam angle, the lower the illumination, and some will also filter, so that some wavelengths cannot penetrate. , causing color shift, such as re-interference processing on the surface (for example: sanding), the light transmittance is lower due to the natural phenomenon of geometric optics, so the substrate used for the diffusion plate should be selected with a lower refractive index. Well, the interference with light will be lower.
At present, there are polystyrene (PS), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polyethylene terephthalate. Ester (PET), acrylic (PMMA), acrylic (MMA), etc.
The PP diffuser uses special light-diffusing materials and additives to extrude the optical materials produced in the 10,000-class clean room. It exhibits high light transmittance and good light source shielding. The problem of glare and glare is an ideal material for secondary lighting of secondary lighting, and an innovative material that maximizes the luminous efficacy of lighting fixtures.
