Outdoor Waterproof Ultra-Thin LED Light Guide Plate

What is the working principle of laser dotting LGP?

The reflection points of the light sources close to the two sides of the light guide plate are small and round and spaced apart, while the reflection points at the middle part of the light guide plate are close and roughly called ellipse. When light enters the light guide plate from both sides of the light source and hits the reflection point, it is diffusely reflected to the surface of the laser dotting LGP: the other part is the light directly penetrates the light guide plate to the surface. The closer the light guide is to the light source, the stronger the direct light, and the weaker the farther away. On the other hand, the reflection points close to the light source are small and distant, and the diffusely reflected light is less. On the contrary, those from the distant light source are thick and tight. The light reflected by the dots is richer. After these lights are complexly merged, the effect of the entire laser dotting LGP is achieved.
