Light-emitting diodes are commonly used light-emitting devices that emit energy through the recombination of electrons and holes to emit light. They are widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy, and have a wide range of uses in modern society, such as lighting, flat panel displays, and medical devices. LED lights are light-emitting diodes. The reason why LED lights can be widely used is the light guide plate. How much do you know about laser dotting LGP? I will expand on it for you.
Here is the list of the article:
What is the working principle of laser dotting LGP?
What are the advantages of laser dotting LGP?
How to produce light guide plate?
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.
The LED, which is made of laser dotting LGP, has so many advantages that it attracts many costumers to purchase.
1) The light made by the light guide plate has high brightness and uniform light;
2) The light of the lamp is softer and not dazzling;
3) The laser dotting LGP can absorb blue light, so the lamp made of the light guide plate has a certain effect on preventing myopia.
4) The production cost of the laser dotting LGP is higher, so the quality is better than normal lights.
In recent years, the process of manufacturing light guide plates has gradually matured. Due to space limitations, we only introduce a method of making light guide plates，Injection Molding.
This method is to fill the molten molding material into a closed mold under high pressure. The light guide plate and the microstructure are required to be completed simultaneously in the injection molding, and the mold must be made quite strong, so the mold price is also quite expensive, so it must be mass-produced in order to deduct the cost of the high-priced mold. The single-sided microstructure array light guide plate generally adopts the manufacturing process of injection molding, and its bottom texture structure can be in the shape of a tiny lens, a microsphere, or a tetrahedral corner prism.
