China's LED industry has developed rapidly in recent years. The production of high-brightness LED chips is expected to exceed 12 billion this year, with a growth rate of 100%. LED products can be widely used in landscape lighting, security lighting, special lighting and general lighting sources, and its market potential is hundreds of billions of yuan. China's semiconductor lighting industry is entering an important period of independent innovation and leaping development. In 2006, the domestic chip market share reached 44%, and has successfully developed more than 140 new products in four major categories, including LED lights and miner's lamps. From 2001 to 2006, the average annual growth rate of sales in the semiconductor lighting market was 48%. According to reports, China has become the world's largest producer and exporter of lighting appliances. In 2006, the output value of China's lighting industry was about 160 billion yuan, with exports of 10 billion US dollars, accounting for 18% of the global market. A battle to seize the commanding heights of the emerging industries of semiconductor lighting has already started around the world. In 2006, the global semiconductor lighting market sales exceeded 7 billion US dollars, with an average annual growth rate of more than 20%. It is expected that the next 5-10 years will form a potential market of 50 billion to 100 billion US dollars.
It is understood that in view of the encouraging development prospects of the semiconductor lighting industry, in recent years, Japan's "21st Century Light Plan", the US "Next Generation Lighting Plan", the EU "Rainbow Plan", the South Korea "GaN Semiconductor Luminous Plan" and other government plans have started. In June 2003, China also established the National Semiconductor Lighting Engineering Coordination Leading Group to launch the National Semiconductor Lighting Project.
According to industry insiders, in the face of the huge temptation of the semiconductor lighting market, the world's three traditional lighting industry giants Philips, General Electric, and OSRAM also cooperated with semiconductor companies to establish a semiconductor lighting company. At present, semiconductor lighting has higher luminous efficiency than incandescent lamps, and is expanding its range of applications at a faster speed. Large-size LCD TV backlights, automotive, commercial and industrial lighting have gradually become the main application areas of LEDs. It is expected that in 2010, LED will surpass fluorescent lamps and enter the general lighting field, and the energy-saving effect will be more significant.
Convincing technologies can drive fundamental technological changes, and the owners of these technologies are inevitably sought after by investors, and if technology can also leverage on energy conservation, then venture capital should be in the limelight. At the moment, there are such technologies and such a field meets all requirements, that is, "semiconductor lighting."
Then, look at the attitude of venture capital. In mid-August, the US energy-saving LED technology supplier Puri Optoelectronics Co., Ltd. announced that it has completed a $23 million C-round venture investment, which serves the demanding solid-state lighting market. For a long time, the Chinese market seems to be a follower of the US market. The new technologies and new models of the United States are all China's need to undertake and imitate.
Semiconductor lighting is optimistic because of its convincing technology. Semiconductor lighting fixtures have significant advantages such as long life, energy saving, safety, and environmental protection. Its power consumption is only 1/10 of that of ordinary lighting. But the semiconductor lighting industry still It is shrouded in a cloud, cost and other reasons lead to its application is still being promoted. However, people in all industries are quite optimistic about the future of semiconductor lighting, and believe that the new light source will set off an alternative sport that will replace traditional fluorescent and incandescent lighting with semiconductor lighting.
As long as one-third of the incandescent lamps are replaced by semiconductor lamps, the country can save 100 billion kWh of electricity every year, which is almost equivalent to saving the annual power generation of a Three Gorges project.
LED industry chain includes LED epitaxial wafer production, LED chip production, LED chip packaging and LED product application. Among them, the epitaxial wafer has the highest technical content, and the chip is second.
Under the efforts of many enterprises and government departments, China's LED industry has initially formed four major regions in the Pearl River Delta, Yangtze River Delta, Southeast China, Beijing and Dalian, and each region has basically formed a relatively complete industrial chain. Generally speaking, China's LED industry pattern has a high degree of industrialization in the south, while the north relies on many universities and research institutions to have strong research and development capabilities. In terms of geographical distribution, the Pearl River Delta and the Yangtze River Delta are the most concentrated areas of the domestic LED industry. The upstream, middle and lower reaches of the industrial chain are relatively complete, and more than 80% of the relevant enterprises in the country are concentrated. It is also the fastest growing region of the domestic LED industry, and the comprehensive advantages of the industry. More obvious. LED equipment and raw material suppliers have settled in these two regions. The convenient connection with the international application market has created a good service and market environment for the development of the LED industry. The industrial cluster effect is gradually emerging.
Domestic production enterprises must solve problems such as the dispersion of research institutions, duplication of topics, and lack of core technologies of independent property rights as soon as possible to enhance the industry competitiveness of the LED industry. First of all, it is necessary to strengthen the industrial basic research of LED to provide continuous intellectual support and development momentum for the development of the industry; secondly, accelerate the development of high-brightness LED and semiconductor lighting technology standards, standardize the industry competition order, and guide the LED industry to develop in a healthy and orderly direction; Third, it is necessary to further expand the application and market development of LED products, so that LED products can penetrate into the fields of general lighting sources, automobile lamps and LED backlights, and expand the market space for the development of the LED industry.
