Crack technology monopoly integration innovation is the trend

LED, as a new type of high efficient solid-state light source has many advantages, the rapid development of technology, looking around the world, countries around the world have developed plans and policies to promote the development of LED industry. At present, the global semiconductor lighting industry formed in the United States, Asia, Europe and the global industrial structure is a situation of tripartite confrontation, the world's major manufacturers in the United States, Japan, Europe and so on, with the core patented GaN based blue and green and white LED technology, also has the advantages in the industrial scale. With the development of LED industry, intellectual property disputes are becoming increasingly fierce, patent litigation is common, so China as a big country in the production and consumption of LED, it is very important to master the core technology patents.

At present, China's LED is not optimistic about the status of intellectual property rights. A survey shows that Nichia, CREE, Lumileds, OSRAM, Toyoda, Gosei, Toshiba and Rohm, the European enterprises not only occupy most of the market share, but also has a 80% - 90% in the field of the original invention patent, especially in the upstream region of material growth and device fabrication of LED industry chain. According to the statistics of the Ministry of Commerce in 2007 only LED exports to the United States involved in the LED product of about $350 million, with the development of the domestic LED industry, intellectual property disputes will be increased, especially in the field of LED white light will have more design of material and structure of patent disputes.

Although the core of the monopoly of white LED industry is monopolized by foreign countries, but with the progress of independent research and development and technology development, China's LED industry development opportunities. LED technology development theoretical value of 400lm/W, semiconductor lighting technology is still far from mature. The existing mainstream industrial technology LED device product efficiency has reached 110lm/W, R & D has reached 161lm/W, but to break through the 200lm/W, may require disruptive technology. At present, there are different technical routes with the mainstream technologies, such as Si substrate epitaxy, GaN homogeneous substrate epitaxy, single chip full spectrum white light, etc.. Gallium nitride as the core of semiconductor lighting is the third generation of semiconductor materials, is only a development of the technology for more than and 20 years, the basic theory is still in the study, as well as decades of development. GaN semiconductor optoelectronics is overcome, as an important breakthrough in optical storage, optical transmission, optical sensing, laser and other semiconductor power devices, has extremely important strategic significance to the development of a new generation of information technology.

Through the implementation of the national semiconductor lighting project "and the 11th Five-Year 863 plan, China in LED epitaxial material, chip manufacturing, packaging, phosphor and other areas have appeared independent intellectual property rights unit technology, and part of the core technology with originality, initially formed from the upstream chip, material preparation, device packaging and midstream the lower the integrated application of relatively complete industrial system and development. If the route Si LED substrate technology Nanchang University from upstream of the substrate and the extension of avoiding the related patents in the United States and Japan, the industrialization of international leading level; semiconductor lighting R & D center of Chinese Academy of Sciences developed a new type power characteristic chip (strip structure, P, n composite film double transparent electrode chip, laser stripping), developed 280nm UV LED devices, 20mA output power of milliwatt order, synchronized with the international advanced level; the principle of Nanjing University presented sun spectrum of white LED and developed a prototype device; the Chinese Academy of Sciences Institute of phosphorescent type white light OLED light emitting efficiency has more than 45 lm/W, is the results of international. Therefore, in our country, the core technology of semiconductor lighting, there are some studies on the foundation and development opportunities, as the third generation semiconductor materials, as long as increase investment, pay attention to the patent layout, it is possible to avoid the existing patent barriers. With the promotion of energy-saving emission reduction, optimize the industrial structure, accelerate the transformation of the mode of development, China's semiconductor lighting industry is ushering in a major historical opportunity for independent innovation and leap forward development.

LED long industrial chain, packaging and application of patent development faster. Practical new patent of most companies downstream industry chain have many international giants, it is difficult to form a monopoly in the downstream products, so the integration innovation of the industrial chain to the industry chain collaboration is very important. Application of LED in the lighting field is facing great development opportunities, the opportunity for the domestic LED industry development, not only to expand the industrial and economic scale, more important is a major opportunity to seize the two innovation, establishment of independent intellectual property rights system. The establishment of independent intellectual property rights system in the field of semiconductor lighting applications, and the realization of this goal, must be based on the industry, the full range of continuous scientific and technological innovation on the basis of. Between LED, downstream industries, and the lighting industry need to carry out closer cooperation, trade cooperation increased from simple to more close technical exchanges and cooperation in research and development road of common development and application of the market.

The Ministry of science and Technology launched the "ten city lights" semiconductor lighting demonstration project and the future of the "12th Five-Year" planning will pay more attention to the development of applications, including the construction of standards, consumption concept guidance and market development etc.. In the country to promote the development of the application of the development strategy has reached a consensus, LED as a sunrise industry will usher in a healthy and orderly development.
