LED cooling device technology breakthroughs
"LED semiconductor lighting, the heat has long been unable to effectively solve the problem, as with independent intellectual property rights of independent innovation and technological achievements - a LED cooling device technology, identify the lighting products are currently 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 ", the China Light Industry Federation professor level Senior Engineer Li Kuan On so that.
"We not only solve the heat problem, but also made in full compliance with 'high efficiency, high reliability, low cost' requirements of the LED drive power, a fundamental solution to the development of LED constraints two problems." The results of the 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 experiments, 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.
