Semiconductor lighting sets off the "green revolution" in the lighting industry
China has initially formed a relatively complete industrial chain from epitaxial wafer production, chip preparation to device packaging integration. Under the global energy crisis and increasing environmental protection requirements, low-power, long-life semiconductor lighting has been recognized as an energy-saving in the world. An important way of environmental protection. In 2006, the global semiconductor lighting market exceeded US$7 billion, with an annual growth rate of over 20%. It is expected to form a potential market of US$50 billion to US$100 billion in the next 5-10 years. By 2010, semiconductor lighting is expected to surpass fluorescent lamps and directly enter the general lighting field, which accounts for 15% to 20% of global power consumption. China, whose economy is developing at a high speed, will also set off a "green revolution" in the lighting industry. Alternative to traditional lighting is the trend of semiconductor lighting (LED, LED for short) is a new type of solid-state light source, has shown energy-saving effects in the field of special lighting, such as landscape lighting, it can save 70% energy by replacing neon lights; traffic lights, use it Replacing incandescent lamps can save up to 80%. With the continuous improvement of technology, large-size LCD TV backlights, automotive, commercial and industrial lighting have gradually become the main application areas of LED. According to experts, as a new high-efficiency solid-state light source, semiconductor lighting sources have significant advantages such as long life, energy saving, safety, environmental protection, rich colors, and miniaturization. The semiconductor lamp uses a light-emitting diode as a new light source. Under the same brightness, the power consumption is only 1/10 of that of an ordinary incandescent lamp, and the service life can be extended by 100 times. It is widely believed in the industry that, like transistors instead of tubes, semiconductor lamps will replace traditional incandescent and fluorescent lamps. The US Department of Energy once predicted that by 2010, 55% of incandescent lamps and fluorescent lamps in the United States will be replaced by semiconductor lamps. The annual electricity bill will reach 35 billion US dollars, and semiconductor lamps will form a large industry of 50 billion US dollars. Chen Lianghui, an academician of the Chinese Academy of Engineering, said that energy conservation and environmental protection will be the mainstream of future social industrial development. The development of semiconductor lighting will not only help solve energy crisis and environmental problems, but also drive traditional industries, and will greatly improve people's quality of life. At present, the global energy crisis is becoming more and more serious, and semiconductor lighting can achieve the purpose of saving electricity. It is estimated that in 2010, China's power generation will reach 2.7 trillion kWh, and lighting power consumption will be about 300 billion kWh; if semiconductor lighting enters 1/3 of the lighting market in 2010, it can save 30% of electricity, that is, annual energy saving of 100 billion kWh, at least It is equivalent to the power generation of a Three Gorges Project. China's LED industry chain has initially formed. At present, China has certain technical and industrial bases in this field. China's first self-developed LED is only a few months behind the world's first LED. Generally speaking, the technical level of China's semiconductor light-emitting diode industry is only about three years away from developed countries. Through the support of scientific plans such as the 863 Program, China has initially formed a relatively complete LED industry chain from epitaxial wafer production, chip fabrication to device packaging integration applications. While the LED production capacity of local Chinese companies continues to expand, foreign investors have also increased their investment in China. At present, there are more than 500 companies engaged in semiconductor lighting in China, employing more than 30,000 people. Through the continuous efforts of enterprises and scientific research institutions, China has a large number of low-end and low-end LED products in the fields of display screens and traffic signals, and has formed certain development technologies and independent intellectual property rights. At the same time of the rapid development of the LED industry, China has initially established several large LED industry bases. According to the person in charge of the Shenzhen Science and Technology Information Bureau, there are currently 740 LED companies in Shenzhen, accounting for 44.3% of the total number of similar enterprises in the country. It is the largest LED enterprise gathering place in the country. CCID Consulting, a subsidiary of the China Electronics and Information Industry Development Research Institute (CCID Group) of the Ministry of Information Industry, expects that more foreign LED companies will enter China in the next few years, and the production capacity of Chinese local LED companies will also Further improvement, China will become another LED industry base after Japan, Taiwan, and South Korea. Policy support paves the way for the development of the LED industry In recent years, the Chinese government has introduced some policies to promote the development of the LED lighting industry. During the “Eleventh Five-Year Plan†period, the National Development and Reform Commission will focus on promoting efficient energy-saving lighting systems in public facilities, hotels, commercial buildings, office buildings, stadiums, and residential buildings. The state will also strictly enter the market for lighting products. Products that fail to meet the mandatory performance standards shall not be produced or sold. Buildings that fail to meet the energy-saving standards for building lighting shall not be constructed. The state will establish an incentive mechanism to accelerate the promotion and application of high-efficiency lighting products, and research and propose fiscal and taxation policies that encourage the production and use of high-efficiency lighting products. These policy measures will pave the way for the development of China's LED industry. The Ministry of Science and Technology officially issued a document, Fangda Group Co., Ltd. won the bid to undertake the national "Eleventh Five-Year" period 863 program of the semiconductor lighting project "high-efficiency high-power GaN LED chip and semiconductor lighting white light source manufacturing technology." The Ministry of Science and Technology allocated a special fund of 6.86 million yuan to support Fangda Group's research and development of the project. At present, China has established Xiamen, Dalian, Shanghai, Nanchang and other cities as the first batch of national semiconductor lighting engineering industrialization bases. All bases have formulated semiconductor lighting industrialization development plans, and comprehensively started base construction work, with a view to forming their own characteristic industries and actively participating in international competition.
