Start lighting engineering China's semiconductor lighting LED industry prospects

LED is a light emitting diode (Light Emitting Diode, referred to as the LED), different types of LED can emit from infrared to blue between the different wavelengths of light, in recent years LED development is the most attractive in the blue light LED coated with phosphor, the blue into white LED products. It can not only efficiently and directly convert electrical energy into light energy, and have the most up to tens of thousands of hours to 100 thousand hours of life, energy saving, environmental protection and have no mercury, small volume, fast response, high seismic can be used in low temperature environment, the light source direction, with advantages of light pollution, and cause less high color saturation and rich color gamut, so LED is known as the new century light source.

As the third lighting revolution following the open flame and incandescent lamp, LED has become one of the most promising high-tech fields in twenty-first Century. National Semiconductor Lighting Technology Department office director Wu Ling said in an interview with LED semiconductor technology as the main energy saving and environmental protection, has been incorporated into the national long-term technology development plan "and the 11th Five-Year" national "863" high-tech industrialization projects and give support.

Lighting project"

China's LED industry to take shape

Semiconductor lighting is triggering a revolution in the world of lighting sources. As a new type of high efficiency solid-state light source, semiconductor lighting has many advantages, such as long life, energy saving, environmental protection, rich color, miniaturization and so on. In recent years, Japan's twenty-first Century light plan, the United States, the next generation of lighting plan, the EU rainbow project, South Korea, GaN semiconductor lighting plan and other government programs have been introduced.

Faced with the huge business opportunities and development prospects of semiconductor lighting, countries around the world have stepped up legislation to encourage the use of energy-saving light source. The European Union, Canada, Australia and the United States will be banned from 2009, 2010 and 2020 incandescent bulbs. Data show that in 2008 the global LED market will increase from $12 billion 500 million in 2004 to $50 billion.

China is the world's largest producer of light sources and lamps, in 2006 sales of 160 billion yuan, but mainly in low-end products, accounting for only the world market of 18%, large and not strong. Development of semiconductor lighting, enhance the international competitiveness of the industry is of great significance. To this end, China launched a national semiconductor lighting project in October 2003, the establishment of the national semiconductor lighting project management office, through policy guidance and incentives to promote the development of domestic LED industry and lighting industry.

At present, to improve the ability of technology innovation and application development of LED products in China gradually, on the position of device reliability is more and more prominent, test methods and standards Jianxingjianjin, all of which were marked Chinese LED industry has entered a new stage of development. After more than 30 years of development, China's LED industry has initially formed a complete industrial chain, including epitaxial wafer production, chip preparation and packaging, as well as LED product applications.

Wu Ling further said, according to the Ministry of science and technology in 11th Five-Year 863 plan, the state in the field of new materials technology, semiconductor lighting project total investment of $350 million. From the overall situation, the project started well, the overall progress smoothly, some of the topics ahead of schedule to achieve the goal. 100 lumens / watt LED manufacturing technology ahead of the completion of the indicators, the company has significantly improved efficiency, has the ability to sustainable technological innovation. As of November 2007, the project has undertaken 17 units to apply for patents, of which the application for invention patents of 152, apply for foreign patents, driven by industrial investment of nearly 2 billion yuan ($241). "

According to statistics, in 2007, the national LED display market reached 7 billion 200 million yuan, representing an increase of $5 billion in 2006 of $44%. 2007 LED chip output value reached 1 billion 500 million yuan, representing an increase of $1 billion 50 million in 2006, in 2007 China's LED packaging output reached $16 billion 800 million, an increase of $14 billion 800 million compared to $15% in 2006. LED production increased by 66 billion in 2006 to reach 82 billion, of which only the high brightness LED output value reached 12 billion yuan, accounting for LED of total sales of $71%. The application of our products in 2007 output value has exceeded 30 billion yuan, has become a full-color LED display, solar LED landscape lamp applications, the world's largest producer and exporter of semiconductor lighting industry is emerging.

Breakthrough patent siege"

Compete for the commanding heights of the LED industry

The competition of high tech industry is the standard competition. Due to many LED related patents, for proprietary vendors, easily lead to a monopoly in the market, and let the other manufacturers must avoid key technology related, and thus the loss of market opportunities, so the lack of R & D capability manufacturers, is difficult to enter the industry.
