LED seize the commanding heights of green lighting

CCTV Spring Festival Gala this year, the stage is very exquisite, attracting hundreds of millions of viewers, the biggest bright spot is the use of LED. "Now all of the major activities are inseparable from the LED, and this is just one of the many applications in LED. National semiconductor lighting engineering research and Industry Alliance Secretary General Wu Ling told reporters.

In order to reveal is called "semiconductor lighting green lighting" (LED) of the mysterious veil, came to the integration technology of semiconductor research center of Chinese Academy of Sciences Institute of semiconductor research reporter the day before. Put on a fully armed dust-proof clothing, after strict disinfection, a careful understanding of the matters needing attention, the reporter followed the staff entered the research center laboratory.

According to the semiconductor research center director Li Jinmin introduced, relying on hardware facilities, R & D and Industry Alliance national semiconductor lighting project (hereinafter referred to as the Union) is the construction of State Key Laboratory of semiconductor lighting joint innovation, it will become an important platform for our common breakthrough in the key technology of LED. The researchers told us that the preparation process is entirely in accordance with the process of industrialization, as a shrinking production workshop.

Pointing to the two wafer slicing looks not what difference, the researchers say their biggest difference, a sapphire substrate, a silicon substrate, a silicon substrate in the field, China has reached the advanced level in the world, with silicon as the substrate material is a technical route for leading the world recognized LED route the industry, which means that our country has a certain advantage in the domain of LED.

The work is in a device, the researchers told reporters, this is the MOCVD machine developed by the Institute of semiconductors, has realized industrialization, this is the essential equipment of large industry chain in the upstream LED chip production in the past, our country has been dependent on imports, imports in the year four hundred or five hundred, every the price is in twenty million yuan of above. China's own development of MOCVD equipment price is only 1/2 of imports, its localization not only get rid of dependence on imported equipment, but also to reduce the cost of LED products, and the market closer.

LED is the third generation of semiconductor materials produced by the light source and display devices, with low power consumption, long life, no pollution, rich colors, strong controllability, etc., is a revolution in lighting and light industry. The emergence of LED, not only a hundred years of tradition, the lighting industry ushered in a large-scale electronic era of digital technology, and application related to information, transportation, medical, agriculture and other fields, its digital feature is the coming era of things of one of the technical support, will cause great changes in human production and life style.

Since the "fifteen", the Ministry of science and technology will support the development of semiconductor lighting technology and industry, launched the national semiconductor lighting project, through scientific research plan, the "863" plan, science and technology support program and other national science and technology plan, the development of technology innovation and continuous support of semiconductor lighting industry. The rapid increase of China's semiconductor lighting industry core technology research and development and innovation ability, form the upstream and midstream epitaxial chip package, downstream of the integrated application of perfect technology innovation chain and have strong competitive international market chain.

Energy saving lamps than 50%, the service life of more than several times, LED obvious advantages, but there are also high prices, some products are not stable enough, the core technology of the lack of breakthrough and other issues. Market application is an important means to solve these problems. To guide and nurture the semiconductor lighting market in 2009, the Ministry of science and Technology launched the semiconductor lighting engineering ("ten city lights") pilot work, as of September 2011, the two batch of 37 pilot city concentrated near 4500 semiconductor lighting enterprises, the total output value of about 140 billion yuan.

In the upstream industry chain alliance, actively build the State Key Laboratory of semiconductor lighting joint innovation, and make full use of the advantages of integrating existing research resources, to activate the stock increment, continued investment and talent incentive mechanism to explore jointly participate in the national basic research, research institutions and enterprises, the formation of an open international R & D entity; in the downstream industry chain, alliance actively carry out the application research, process design and system integration, the development of modular, standardized products, innovative application of multipurpose; through binding legal contracts, the formation of common input, clear division of responsibilities and rights clear, intellectual property sharing, research the rapid industrialization of public technology research and development take the project entity; joint investment, the use of priority, open the formation of different classification research interests Hair platform. In the absence of the LED world standards, members of the union jointly proposed technical specifications, of which 4 have become technical standards, to actively seize the commanding heights made a breakthrough.
