LED light guide quality judgment

There are many kinds of LED light guide plates, and the quality is uneven. Therefore, how to judge the quality of LED light guide plates is a key. The quality problem of LED light guide plate directly affects the brightness, indicating degree and quality of LED panel products such as LED panel light, LED table lamp and ultra-thin light box. Therefore, the quality of LED light guide plate determines the performance of the product.

LED laser light guide plate is still very prominent compared with silk screen light guide plate: energy saving, long life, green, high brightness and high uniformity. However, according to relevant surveys, there are many different quality products on the market, and customers don't even know how to choose. Even some online consulting customers will ask why it is so expensive with the quotes on the market, depending on the quality of the board.

In fact, the inferior products of the market have violated the problems of energy saving, long use time and environmental protection of LED lighting products, especially in the field of integrated ceilings, which seriously affected the healthy development of LED panel lights . Then how should customers distinguish the advantages and disadvantages of the light guide plate?

In fact, it is difficult to see in a short period of time, especially the problem of longevity. However, if the research in this industry is long, there is a certain experience in the quality judgment of PMMA, and it can be judged directly on the basis of the hand. However, the customer pays more attention to the brightness and uniformity of the light guide plate , which can reduce the cost to a certain extent.

At present, the materials used in the light guide plate mainly include pmma and PC, but the transmission efficiency of pmma to light is relatively high, so pmma is used as the substrate, especially in the trend of laser spotting, pmma can be better. In order to adapt to this production process, the laser light guide plate of Yingxing Technology is currently influential in the market.
