Chinese Academy of Sciences to develop high-power LED LED applications to open a new market

Recently, the Chinese Academy of Sciences Hercynian Research Institute (Fujian Institute of Materials) successfully developed with completely independent intellectual property rights of kilowatt-class high-power fluorescent LED lighting, fluorescent ceramic technology to replace the current LED core material fluorescent adhesive in the international LED lighting industry is a major Technological breakthroughs will boost China's LED to replace traditional light sources in an all-round way and reconstruct the ecology of optoelectronics industry, thus creating a new market for high-power LED applications with a market value of 100 billion yuan.

First, a unique patented technology to fill the gaps in the industry. LED lighting in recent years in the civilian market has gradually replaced the traditional light source. But subject to the technical bottleneck of thermal materials, LED high-power lighting is still a worldwide problem. The Institute of Physics, Chinese Academy of Sciences in 2009 successfully developed the first piece of fluorescent ceramics, fluorescent ceramics and fluorescent materials compared with significant thermal conductivity, high luminous efficiency, high reliability. In 2013, in order to promote the industrialization of fluorescent ceramics, Fujian Science and Technology Co., Ltd. funded the technology and set up Fujian Zhongke Core Source Company jointly with the social capital. After nearly three years of research and production in close cooperation, in 2016 have been developed with fluorescent ceramics as packaging materials, with unique packaging and cooling technology of 600-watt and 1000-kilowatt K-COB technology. In June this year, the project completed the global patent layout and entered the initial industrial application. The industry calls it "a revolutionary breakthrough in China's LED industry technology."

At present, the global LED main packaging material fluorescent adhesive has poor thermal conductivity and easy aging and other technical bottlenecks that make LED unable to achieve high power density packaging. In the world's leading Japanese company's products can only be done below 200W, the limit does not exceed 500W. In mining, port terminals, airports, fishing and other high-power lighting applications market, is still dominated by the traditional lighting source. Fujian Institute of Materials through the fluorescent ceramic material innovation breakthrough in high-power LED technology bottlenecks, the LED not only to achieve a higher luminous efficiency, longer life, smaller light failure, but also in the 50 mm diameter ceramic sheet to achieve 1000W more than 100,000 lumens Ultra-high power density light output.

On the other hand, patent barriers are an important reason for restricting the development of China's LED industry for a long time. The current chips and fluorescent plastic patents are owned by foreign enterprises, large-scale domestic LED manufacturers have suffered patent barriers. Fujian Institute of technology, this technology, with independent research and development of transparent fluorescent ceramic materials sintering equipment, highly confidential formula, a unique packaging technology, with equipment, formulations, packaging technology to the chain of complete independent intellectual property rights. At present, this technology has completed 4 PCT applications, more than 30 domestic invention patents have been granted and the global patent layout has been achieved, which will make the patent barriers that long plagued the LED industry in our country break through.

Second, a wide range of applications, a huge market potential. Compared with traditional lamps such as metal halide lamp and high pressure sodium lamp, fluorescent ceramic LED does not contain mercury, pollution-free, environmental protection, and has obvious economic and social benefits. 300W fluorescent ceramic LED replacement for 1000W metal halide lamp, for example, 1000W metal halide lamp price of about 2,000 yuan, the service life of about 1 year; fluorescent ceramic LED price is about double the metal halide lamp, the average saving rate of about 70% , The whole life cycle cost is only 1/3 of the traditional lighting, such as using 10 hours a day as a measure, one year to recover the investment, 5 years can save 12,000 degrees, the annual rate of return of 100%.

Fluorescent ceramic LED innovation will create a new market of hundreds of billions of LED applications. Fujian Science and Technology Co., Ltd. core source of 600W fluorescent ceramic LED production, has been preparing for training in Beijing 2018 Olympic Winter Games instead of the traditional 2000W metal halide lamp. The future of high-power fluorescent ceramic LED replacement of traditional lighting sources can be widely used in urban plaza, large factories and mines, port terminals, stadiums, military aviation, remote exploration and other fields. Statistics show that in 2014 China's metal halide lamp production reached 90 million, with a total power of about 10.8 million kilowatts, such as the fluorescent ceramic LED to replace all, will save 7.56 million kilowatts, equivalent to a total installed capacity of the Three Gorges hydropower station. In order to speed up the promotion of this technology application, Fujian Zhongkexuyuan has united upstream enterprises such as power supply, heat dissipation and contract energy management to form an industrial technology alliance for collaborative innovation. At present, with the high-power fluorescent ceramic LED matching power supply, cooling and other alliance manufacturers have developed the corresponding products, industrial alliances have begun to export downstream enterprise applications complete product technology solutions.

Third, policies to speed up project promotion and application. Fujian Provincial Science and Technology Department attaches great importance to and supports the scientific and technological innovation and R & D work of the CAS. From 2011 onwards every year to major projects of science and technology to arrange 10 million yuan, at the same time to build a major research and development platform, incubator, guided projects and other ways to support the construction of Hercynian. In 2011-2016, a total of 75.95 million yuan will be provided to promote the construction of the Engineering and Technology Research Center and the Incubation Center of Hercynian Research Institute. Among them, in the form of major projects funded 5 million yuan for the Hercynian "kilowatt-class LED" related projects for the "kilowatt LED" research laid the technical foundation.
