As governments around the world reach a consensus on green energy conservation and environmental protection, the industry prospects related to green environmental protection and energy conservation will be bright in the future, and LED semiconductor technology with hot industry will become one of the most promising high-tech fields.
At present, China's semiconductor LED as a major technology for energy conservation and environmental protection has been included in the national medium and long-term science and technology development plan and the "Eleventh Five-Year" national "863" high-tech industrialization major project, and has received strong support.
LED into the mainstream of the market
Globally, the LED semiconductor technology industry has formed an industry distribution and competition pattern dominated by the three regions of the United States, Asia and Europe. With the rapid development of the market, major manufacturers in the United States, Japan, and Europe have expanded their production and accelerated their market share.
From the domestic market point of view, China's current LED product development and application areas are still immature, domestic independent LED chips, epitaxial film production is still limited, the products are mainly in the middle and low-end, and the gap with foreign countries is very large.
The scale of industrialization is too small, and can only meet the demand of domestic packaging enterprises by 20%-30%. Most high-performance LEDs and high-power LED products are dependent on imports.
In addition, in the application market of LEDs, there are restrictions caused by the variety of products and varieties, especially in the field of general lighting, due to the lack of technology, it is impossible to scale and popularize applications.
In 2008, global LE upgraded its core technology and achieved mass production is the most critical step in the development of the LED industry. The LED market reached 8 billion US dollars, and the market share of the entire LE products increased from 40% in 2001 to more than 70% in 2005. Among them, the average annual growth rate of high-brightness LEDs reached 46% between 1995 and 2004.
The US Market Research Corporation (CIR) predicts that the global LED market will grow at an average annual rate of more than 30%, and the market size will exceed $10 billion in 2009.
In recent years, with the expansion of LEDs in new applications such as lighting, small-sized panel backlights, and indoor lighting, high-brightness LEDs have been in a high-speed growth stage for the past few years, and the proportion in LEDs will gradually increase, becoming the mainstream of LEDs. product.
Increased policy support
On January 7th, commissioned by the High-tech Development and Industry Department of the Ministry of Science and Technology, sponsored by the National Semiconductor Engineering R&D and Industry Alliance, the “Ten Cities and Ten Thousand†Semiconductor Lighting Application Pilot City Work Conference hosted by Harbin Science and Technology Bureau was held in Huaqi Hotel, Harbin. .
Wang Zhixue, deputy secretary-general of the Ministry of Science and Technology, pointed out at the meeting that semiconductor lighting is one of the few key core technologies that have gradually mastered the market demand prospects, with low resource energy consumption, large driving coefficient, many employment opportunities, and comprehensive benefits. Wait for strategic emerging industries.
The current lighting industry is facing the transformation of the three major aspects of industry, technology and knowledge. Through scientific and rational planning and investment, China is likely to seize the commanding heights of international semiconductor lighting technology and industry, and become a strategic pilot industry in the future optoelectronic field. The work of “Ten Cities and Ten Thousands†will play an important role in leading the rapid development of the semiconductor lighting industry.
At the Neon Light Work Conference of China Lighting Association held in Jinan, it was also pointed out that lighting appliances require more environmental protection, energy saving and light pollution reduction. Green lighting has become a new trend in the development of domestic lighting industry.
In the past, the energy consumption of an incandescent lamp as a lighting system was very large, and the semiconductor lamp used a light-emitting diode (LED) as a new light source, which consumes only 1/10 of the power of an ordinary incandescent lamp, and the life can be extended by 100 times. Maintenance, environmental protection and other characteristics.
Since 2007, Australia, Canada, the United States, the European Union, Japan and Taiwan and other countries and regions have announced that they will gradually phase out incandescent lamps and develop LED lighting as the focus of the global industry. Replacing traditional incandescent and fluorescent lamps with semiconductor lamps will have a huge impact on energy and environmental protection.
Bai Xuejun, sales director of Beijing Taifu Anjing Technology Co., Ltd., said in an interview with the reporter of China United Business Daily: "LEDs are compared with old products in terms of brightness, power consumption, viewing angle and refresh rate. More advantages, LED energy saving effect is much better in terms of energy saving, so the future development of LED in the market is very huge."
The US Department of Energy predicts that this year, 55% of incandescent and fluorescent lamps in the United States will be replaced by semiconductor lamps, saving $35 billion in electricity annually. Japan proposed that large-scale replacement of traditional incandescent lamps with semiconductor lamps in 2006. According to estimates, in the United States only seven years later, semiconductor lighting may form a large industry of 50 billion US dollars.
Perfect industrial layout
China has a huge lighting industry and lighting market. China is now one of the world's largest producers and exporters of lighting appliances. With the support of the “863†plan and other scientific and technological plans, China has initially formed a relatively complete industrial chain from epitaxial wafer production, chip fabrication, and device packaging integration applications. Now there are more than 400 companies engaged in the scale production of semiconductor LED devices and lighting systems nationwide. Home, packaging has occupied a considerable share in the international market.
Under the impetus of “National Semiconductor Lighting Projectâ€, seven national semiconductor lighting engineering industrialization bases have been formed in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang. The Yangtze River Delta, the Pearl River Delta, the Triangle and the North have become the gathering places for the development of China's LED industry.
Throughout the global market, examples of government funding to promote industrial development abound. For example, the spread of solar power in Germany to every household is a good example of success.
In 2009, the Chinese government stimulated domestic demand and launched the “Ten Cities and Ten Thousands†LED lighting popularization and energy-saving campaign. Up to now, it has been clear that the national LED lighting should exceed 10,000 lamps. National street lamps and 24-hour continuous use of tunnel lights have become the first replacement. Key projects.
Metros in Beijing, Shanghai, Guangzhou, and Shenzhen have started and popularized LED fluorescent energy-saving projects. Bringing the technology and production capacity of the LED lighting industry to a comprehensive development of high-tech depth, creating a new enterprise in the industrial chain.
Under the stimulation of the country's policy of expanding domestic demand, the LED lighting industry has developed rapidly, and its upstream, middle and downstream industrial chains have also been improved accordingly. At the same time, all relevant technologies in the LED lighting industry chain can be improved and developed on the basis of practical application.
At present, South China, East China, and North China have shown the booming development of the LED lighting industry. I believe that the LED industry will spread the motherland in the near future.
