There are many types of diffusers on the market now. The diffuser is a scientific production process that evenly distributes the diffuser inside the plate, so that a certain optical effect can be achieved.
The diffuser is after the light is irradiated on the diffuser, the light diffuser inside it will play a role, so that part of the light will be refracted, reflected and scattered. In this way, the purity of the transmitted light can be ensured and the light source can also be blocked.
The specific principle of optical action is as follows: when light is emitted, it will encounter the medium. As long as the medium encountered by the light is different from the previous one, different media will produce different refractive indexes, so light will be affected by the refractive index. When reflection or refraction occurs, it will penetrate or be absorbed by the blocking medium because of the blocking medium, and the part of the light that passes through is diffused by the plate. For this blocking medium, the greater its refractive index, the stronger the dispersion, and the smaller the amount of light passing through the diffuser. The more it interferes with light, the amount of light passing will be limited. A medium with a rough surface is also highly resistant to light. The refractive index of the blocking medium and the position from the light source also affect the light diffusion angle. For large angles, the amount of light transmitted is small, which is not suitable for lighting.
