The large feature of the diffuser

The large feature of the diffuser is that it interferes a lot with light. No matter how much the original design has a light distribution curve, 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 proved that the larger the beam angle, the lower the illumination, and some will also filter, so that some wavelengths cannot penetrate. Causes color shift, such as re-interference processing on the surface (for example: sanding, embossing), the light transmittance is lower due to the natural phenomenon of geometric optics, so the refractive index should be selected as the substrate for the diffusion plate. The lower the better, the lower the interference with light.

Type of diffuser

According to the optical principle classification, the diffusion plate is only divided into two types, one is that the angle of the beam will be increased to maintain the original angle.

According to the material classification, glass, polystyrene (PS), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate ( Translucent polymeric materials or synthetic materials such as PET), acrylic (PMMA), acrylic acid (MMA), etc. can be made into diffusion materials for different purposes.

The types of diffusing plates can be classified into a gas diffusing plate, a sound diffusing plate, a liquid diffusing plate, a light diffusing plate, a taste diffusing plate, and a light diffusing plate, and materials which can uniformly disperse molecules are collectively referred to as a diffusing plate.

Air diffuser --> Generally used to reduce the sound generated by the flow of air, such as: car silencer.

Sound diffuser --> Generally used to eliminate the sound echoed by hard objects, such as the walls or ceiling of a concert hall.

Liquid Diffusers --> Generally used to make liquids into misty or smaller molecules to evenly distribute them, for example, water curtains for greenhouses.

Flavor diffusing plate --> Generally used to eliminate or disperse the taste to reduce it, for example: the gas canister of the gas mask or the filter can of the water filter.

Light diffuser --> Generally used to prevent glare from giving the visual a comfortable environment, such as a diffuser in front of the camera flash.
