Rare earth + semiconductor chips: a new generation of AC LED lighting technology is expected to leveraging trillion industry

The morning of June 16th, Chinese Academy of Sciences expert group composed of 10 Chinese Academy of Sciences, 2 National Natural Science Fund Committee Leaders and three industry experts came to Chengdu, the Chinese Academy of Sciences Changchun Applied Chemistry Institute and Chengdu high tech Zone enterprises Sichuan Sony light Limited by Share Ltd R & D cooperation "application" luminous afterglow luminescent materials of rare earth LED controllable life and its development semiconductor lighting in the achievement appraisal. The Chinese Academy of Sciences evaluation group agreed through the identification, and that the project has achieved a major breakthrough in the rare earth luminescent materials and the global semiconductor lighting technology and originality, rare earth luminescent materials can effectively solve the problem of international has failed to break the strobe AC LED lighting equipment; the results achieved from basic research to the industrialization of the leap, reached the international the leading level, to become the world's only China master flash products through the exchange of LED rare earth phosphor production low countries. The popularization and application of this technology will effectively prolong the service life of AC LED lighting equipment and reduce the energy consumption of lighting equipment. The Chinese Academy of Sciences identified group of Sony light Changchun cooperation with the Chinese Academy of Sciences Institute, a new generation of AC LED lighting technology independent research and development, the "made in Chengdu" LED lighting technology to the world leading level, the use of the technology will have hundreds of billions or even tens of thousands of new industrial grade lighting billion in the next five to ten years.

According to Sony source chairman Zhang Ming introduction, Sony light spent nearly 10 years, and the Chinese Academy of Sciences Changchun Applied Chemistry by Zhang Hongjie Li Chengyu, the two researchers to research, independent research and development of a new generation of LED lighting technology. At present, most of the global LED lighting manufacturers are DC LED lighting devices, but the DC LED lighting equipment all need to configure an AC drive to the DC drive, because the service life of components is much lower than the service life of the LED, so the service life is short of LED DC to AC LED, and significantly increased the cost of LED lighting equipment. But the global R & D AC LED manufacturers have been unable to solve a bottleneck is the communication of LED lighting stroboscopic flicker problem, particularly large harm to human eyes; but the Chinese Academy of Sciences Changchun Institute of Applied Chemistry and Sony light successfully multi-color long afterglow luminescence technology and semiconductor lighting technology, to solve the problem of There was no parallel in history. strobe PHILPS, OSRAM and other international giants are unable to solve the lighting.

In addition, the new generation of light source R & D LED lighting lighting equipment than the general DC 15% LED energy saving, energy saving than the general energy-saving lamps 50%, while only the traditional incandescent energy consumption of 1/8-1/10. For example, if all of the current use of Chengdu is a general energy-saving lamps, then replaced by AC technology LED lighting equipment, the existing power consumption can light up two Chengdu. "The Chinese Academy of Sciences expert Changchun Applied Chemistry Zhang Hongjie, mercury vapor lamps currently on the market for containing a certain amount of incandescent lamp is the tungsten light, these heavy metals have little influence on human health, the recycling of waste after is a troublesome thing; but the use of rare earth luminescent materials for a new generation of LED AC lighting equipment is contained rare earth fluorescent powder and semiconductor electronic components, these materials are harmless to human body and easy to handle. Because the lighting energy efficiency produced by Sony light outstanding and the degree of stability of the power grid protection, the State Ministry of science and technology, National Theatre, Shanghai World Expo, Shenzhen metro, Chengdu Metro and other agencies and many large shopping malls and Hotels with Sony light products. Every breakthrough of new technology will bring the innovation of the global electrification industry, but also a revolution in energy saving. Compared with the traditional incandescent lamp, an exchange of LED bulbs can save electricity 73 yuan a year (87.6-14.6), according to a calculation using a light bulb, a family can save electricity costs $2920 a year. In the next 5 years if Sony light can reach the annual output value of 32 billion, a total of 5 years can save electricity 14 billion 500 million degrees, is approximately equal to the annual generating capacity of the Three Gorges power station 1/10, saving approximately 6 million tons of standard coal, less about 14 million tons of carbon dioxide emissions. Sony light source chairman Zhang Ming introduction.

Background story:

In the new generation of AC LED R & D Application breakthroughs in the field of Sony light source to become the target of global lighting predators. 7 years ago, when Sony light just in the long afterglow luminescent materials technology has made some achievements, Beijing suddenly received a court summons, a well-known Japanese high-tech multinational corporation, rare earth luminescent materials sued Sony light the patent infringement of them! "We immediately pay 500 thousand yuan, the closure of the factory, the destruction of the mold and our equipment. "So that the new light source and the Chinese Academy of Sciences, Changchun Institute of Applied Chemistry are very angry, but also hit. "This is the fundamental material of our own invention, why would simply become Japanese companies things? We Chinese in 70s are already in the textbook on the rare earth resources, what became their technology and products?" Sony source chairman Zhang Ming discovered each other's malicious, after investigation, found that the situation is even worse: prior to this, the foreign companies also use the same way in the United States and Germany won the three lawsuit, is the intellectual property litigation concerning rare earth industry.

Although not a friendly, and backing is not small, then small Sony light choice fight hand to hand with no compromise. After that, Sony light source began to prepare for the war, during the Beijing, Guangdong, to Changsha, to
