"For LED semiconductor lighting, the heat problem has not been effectively resolved for a long time, as with independent intellectual property rights of independent innovation and technological achievements - a LED cooling device technology, identify the lighting products are currently problems Of the key nodes, the successful elimination of obstacles, the use of wire form and forced cooling fan to achieve a better cooling effect. "At a recent" LED heat dissipation device technology exchange seminar and press conference ", China Light Industry Federation, said Professor Li Kuanan, senior engineer.

"We not only solve the heat problem, but also made in full compliance with 'high efficiency, high reliability, low-cost' LED drive power requirements, fundamentally solve the two problems restricting the development of LED." The results inventor, Senior Engineer Zhang Yixing said.

"LED is known as illuminating the 21st century green light source, is widely used in production and life.With the further improvement of economic and social standards of living, LED technology, especially high-end LED technology and products will have more in-depth application. However, the current situation, whether ordinary lighting or high-end lighting, its development is mainly affected by heat and drive power of this problem.However, the current situation, whether it is general lighting or high-end lighting, its development is mainly affected by heat dissipation and driving power supply this is an important driving force for LED technology innovation and industrial explosive growth. Two technical problems constraints.

According to reports, the technology has made in full compliance with "high efficiency, high reliability, low cost" requirements of the LED drive power, the drive power efficiency of 94%, fundamentally eliminate the serious impact LED drive power supply stable operation of the " Problem; heat problems also get a better solution. "Through repeated research and experiment, and finally reached a better cooling effect, there is no electrolytic capacitor overheating, inrush current damage to the switch and power frequency flicker and other issues." Zhang Yixing said.

Zhang Yixing said, "passive power factor correction circuit" to "impossible" into "possible" to solve the two key nodes present. Experts believe that the technology to improve the power factor, the elimination of harmonic current, the power loss, performance, and low cost, and the use of wire form and fan forced cooling, small size, light weight, better cooling effect. "

It is reported that the Secretary-General of Beijing Institute of Electrical Lighting Chang Yi, National Electric Light Source Quality Supervision and Inspection Center, Professor Yang Zheng, senior engineer of the expert group agreed that the technology LED lighting products identified the key problems of the existing problems, with A certain degree of innovation, advanced, as soon as possible to form a complete LED lighting products, in order to promote the market.
