LED Light Guide Working Principle

The reflection points near the light sources on both sides of the light guide plate are slightly rounded and spaced apart, and the reflection points in the middle portion of the light guide plate are tight and coarse and slightly oval. When light enters the light guide plate from the two side light sources and hits the reflection point, it diffuses and reflects to the surface of the light guide plate: the other part is that the light directly penetrates the light guide plate to reach the surface. The closer the light is to the light guide plate of the light source, the stronger the direct light is, and the farther away is. On the other hand, the reflection point close to the light source is small and alienated, and the diffused light is less, and the far distance light source is thick and compact. The light reflected by the dots is richer. These lights are complexly combined to achieve the effect that the entire light guide plate is bright.
