High brightness LED investment hot industry chain construction into focus

Recently, domestic investment boom Youxian high brightness white LED. There is news that the semiconductor white LED industry base will be in late August or early September in Shanghai started, the initial monthly production capacity of up to 1 million single chip. At the same time, Yangzhou also claimed that LED is to build the industrial base, Yangzhou "sword" attitude to enter the LED industry, and strive to 2010 in the development zone is formed in the upper middle and lower reaches of the basic convergence of LED industry chain. Because of the high brightness LED has three outstanding advantages: energy saving, environmental protection, long life, its application fields are expanding. The development of foreign LED technology and industry, in recent years, the development is very rapid, especially in the blue light, white light, power LED and application have a greater breakthrough. There are more than 10 thousand patent applications for LED, forming a high degree of technical monopoly. Domestic enterprises in recent years due to state and local governments, universities, and the related research of LED industry, have invested in funds, manpower and material resources is large, in the LED technology research and industrialization have great development, another round of domestic LED investment gradually, the construction of LED industry chain this has become the focus of investment.

Policy guidance is very important

Although in recent years, the rapid development of China's LED industry, especially the rapid development of high brightness LED. But with the international gap is still large, to analysis Chinese optical photonics Optoelectronics Industry Association branch secretary Peng Wanhua in an interview with reporters, the main problem is that research institutions are too scattered and repeated research and lack of independent intellectual property core technology. High performance LED and power LED products have to rely on imports, industrial scale is small, low level, lack of competitiveness. To this end, how to address these issues, and accelerate the development of LED industry, Peng Wanhua suggested that government policy guidance, macro-control is very important. The government should introduce policies conducive to the development of the LED industry, in the course of the development process to guide and macro-control. The state should take the development of semiconductor lighting industry as a major energy conservation projects, the introduction of relevant preferential policies to give priority to support. Study on the dispersion and repeated phenomenon, with the control of project investment funds for research and development measures to guide and control, become focused on, division of labor, sharing mode, key support and encouragement, with independent intellectual property rights innovation project, make our country in the field of LED research to catch up with the world advanced level as soon as possible. Similarly, the use of government guidance and control methods, LED small scale of the relevant enterprises before the process of integration, merger, joint venture, centralized resources, expanding the level of industrialization. After the process of packaging enterprises to guide investment, focusing on building, expanding the scale of industrialization, so that the level of LED industrialization in the international competition." Peng Wanhua said.

Strengthen basic research and development

Judging from the performance and quality of LED products in China, it is still in the middle and lower levels. The main reason lies in the lack of basic research, development, eager to process and sell LED products. To this end, Peng Wanhua stressed, should strengthen the research and development of high brightness LED and power LED epitaxy, chip, mainly to improve the internal quantum efficiency and the external quantum efficiency of light, improve product performance, stability, consistency and reliability. To improve the rate of industrialization into the finished product, the power LED to break through, to have the core technology of independent intellectual property rights." Peng Wanhua stressed.

LED industry development can not be separated from the supply of materials and accessories in Kaiyuan. At present, the main chain of LED products in the industry is still dependent on imports of raw materials, experts believe that it is necessary to strengthen investment in this area and research and development, so that as soon as possible localization.

LED industry development of the key equipment is also the basis for industrial development, the domestic LED manufacturing equipment, testing equipment, such as the gap with foreign countries is still large. Is the main extension equipment MOCVD and before the process of chip manufacturing equipment and process of automatic packaging equipment and automated test equipment, domestic experts hope that the relevant departments and enterprises to strengthen investment, accelerate the development of supporting industries, as soon as LED, formed a complete industrial chain of LED. "Zhejiang University three color Instrument Co., Ltd. in the measurement of white LED parameters and uniformity, LED planar light-emitting (Bei Guangyuan) characteristics and LED reliability has been developed and produced these test instruments." Peng Wanhua introduction.

Expand the application market

Expand the popularization and application of LED products, expanding the market is the biggest driving force to promote the development of LED industry, should be given high priority. From the current domestic LED market analysis, there are still many problems, Peng Wanhua think, because there is no uniform testing standards and reliability of assessment indicators, the market often appear LED products filled with bad, this life up to 100 thousand hours, the price confusion, it will have to LED the product of distrust, attention should be paid to. In this appeal to the relevant departments as soon as possible to develop the relevant standards, assessment methods, and the establishment of an authoritative testing center for testing and unified measurement." Peng Wanhua said.

In LED product application development, experts suggest that we should focus on three aspects of development.

We should accelerate the development of semiconductor lighting applications, here mainly refers to the color of LED lighting, including landscape lighting and decorative lighting, and special lighting, including lamp, beacon lights, traffic lights, security lights, portable and low power for lights and general lighting source, this is the biggest potential market, will gradually enter the market, also the application of solar energy LED lighting products should also be concerned about.

Secondly, the development of various sizes L
