LED heat sink technology has a new breakthrough effect to further upgrade

"The LED semiconductor lighting, heating problem has not been solved effectively, radiation device as independent innovation and technological achievements with independent intellectual property rights -- a kind of LED, identify the key nodes of the current problems of lighting products, successfully remove obstacles, heat recovery forced wire form and fan, achieve cooling effect good. In the recently held a LED heat exchange technology seminars and press conference, China Light Industry Federation professor level senior engineer Li Kuanan said so.

"We not only solve the problem of heat dissipation, but also made a fully meet the 'high efficiency, high reliability, low cost' requirements of LED power supply, a fundamental solution to the development of the two constraints LED. The results inventor, senior engineer Zhang Yixing said.

"LED is known as a green light source that illuminates twenty-first Century, and is widely used in production and life. With the further improvement of economic and social living standards, LED technology, especially high-end LED technology and products will have a more in-depth application. Zhang Yixing said, the country's great efforts to build, is an important driving force for LED technological innovation and industrial explosive growth. However, in view of the current situation, whether it is the general lighting or high-end lighting, its development is mainly affected by the two technical problems of heat dissipation and power supply constraints. "

According to reports, the technology to fully comply with the "high efficiency, high reliability and low cost requirements of the LED driving power supply, the power supply efficiency reached 94%, fundamentally eliminate the serious effect of LED driving power supply and stable operation of the" old "; the heat problem has gotten better solution. "Through repeated investigations and experiments, and finally reached a good cooling effect, there is no electrolytic capacitor overheating, inrush current damage switch and power frequency flicker and other issues. Zhang Yixing said.

Zhang Yixing said, passive power factor correction circuit can not be changed to possible, solve the existing two key nodes. Experts believe that this technology improves the power factor, eliminate harmonic current, power loss, good performance, low cost, and the use of wire and fan for heat dissipation, small volume and light weight, good heat dissipation effect. "

It is reported that the expert group Beijing Lighting Association Secretary General Chang Yi, Professor of the national electric light source quality supervision and Inspection Center Senior Engineer Yang Zheng and other experts agree that identify the key nodes of LED lighting products of the current problems of the technology, innovative, advanced, LED lighting products should be formed in order to complete as soon as possible. The promotion to the market.
