My opinion on laser light spot design solution for LED light guide plate

The wide use of LED light guide plates in LED energy-saving lamps makes the design of laser light guides for LED light guide plates more and more important. It has become the most important link of LED light guide plates. It has a significant technological content and directly affects LED energy-saving lamps. Brightness, transparency.

With the further development of LED light guide plate technology, the output capability of light transmittance has been further improved. The development of edge light type has become the mainstream of current LED lighting. This method is most widely used in LED panel lights and integrated ceilings.

If the silk screen light guide plate works at a higher temperature, it will not only affect the light transmittance of the light guide plate, but also face problems such as easy yellowing and severe light decay. Among the current LED lighting manufacturers, some enterprises will control the cost. The use of inferior silk screen light guides, such LED lighting products just touched the end user's questioning the quality of the product, affecting the long-term development of the industry.

According to the author's understanding of the industry, some companies claim to have begun to pay attention to the trend of standardization, but since the design of the light guide plate must be tailored according to the module, the standard seems to become difficult to implement. However, you can refer to the Huaqiang LED website to establish a database of LED products, and require relevant reference data. Even for different types of products, you can make different references in design, quality and price.

When it comes to the light guide plate product standard, it also begins to involve the light guide plate dot design. This is an important part of determining the light transmittance of the product (the material requirements are also very important, the light transmittance of the high quality sheet and the inferior sheet will be 10% difference). If the same plate, uniform specifications, laser and silk screen production methods, the difference has been maintained at 5% - 30% difference. The laser is densely arranged in small-sized dots, and the precision design is higher, so it can be higher than the screen printing by 30%.
