As one of the important components of the LED industry, the light guide plate plays a key role in the quality of the LDE product. In the case of the same product, the difference of the light guide plate seriously affects the quality of the whole product. So what is the impact of the uniformity of the light guide on the LED products?
At present, the silk screen light guide plate is the leading of the lighting industry, but the silk screen light guide plate is easy to yellow, the brightness, especially the uniformity is not good, and the silk screen light guide plate does not meet the environmental protection standard, which is another fatal shortcoming of the silk screen light guide plate, Huaxin Photoelectric on the silk screen light guide plate and laser engraved light guide plate made a yellow flower experiment, under the same conditions, some of the lamps used silk screen light guide plate, a part of the lamp with a laser light guide plate for three months of continuous lighting experiment, found in three months After that, the brightness was only 85% of the initial time, that is, in the past 3 months, 15% of the fading occurred. The laser engraved light guide plate has almost no change.
This actual data has greatly shocked the LED lighting manufacturers. Because silk screen printing is made by chemical method, a series of chemical reactions will occur during the process of use, so that the bumps on the silk screen light guide plate are gradually consumed, and finally the surface of the light guide plate tends to be smooth, and the guide cannot be realized. The effect of light, this will give the company a great price in the maintenance of future lamps.
In line with the call for energy conservation and environmental protection, with the rise of the light guide plate industry, Huaxin Technology has carried out bold innovations, adopting a laser plate method for the light guide plate, using laser equipment to make an Internet spot on the surface of the light guide plate, and laser engraving light guide plate is a kind of physics. The processing of the way to form dense pits, the use of the optical principle of the concave lens to achieve the output of light, and achieve the best uniformity.
The laser engraving light guide plate is a technological revolution of the light guide plate. The continuous improvement of this technology not only meets the requirements of energy saving and environmental protection, but also the brightness and uniformity are recognized by the majority of LDE manufacturers. The laser engraved light guide plate not only realizes the cost reduction of LED products. It also makes the popularity of LED lighting easier, and Xiaobian believes that laser engraving light guides will set off a wave in the LDE industry.
