Short, different types of LED can be sent from the infrared to the blue light of different wavelengths between, the most interesting development in recent years, LED is the blue LED coated with phosphor, the blue light into white light of white LED products . It not only can efficiently direct the energy into light energy, and have the most up to tens of thousands of hours to 100,000 hours of life, and have energy-saving, environmentally friendly mercury-free, small size, fast response, high seismic can be used in low-temperature environment, with a directional light source, resulting in less light pollution, and the color saturation and color gamut, rich, etc, so the new LED light source known as the century. As following the fire and Incandescent After the third Illumination Revolution, semiconductor lighting (LED) into the 21st century the most promising areas of high technology. Office of Science and Technology National Semiconductor Lighting main Renwu Ling said in an interview, the semiconductor LED as energy saving, environmental protection, the major technologies have been incorporated into the national long-term technology development plan with the "Eleventh Five-Year" national "863" high-tech industries and major projects to give support. Start "lighting" LED industry begun to take shape in China Worldwide semiconductor lighting is causing a revolution in lighting. As a new and efficient solid light source, semiconductor lighting with long life, energy saving, color-rich, the advantages of miniaturization, will be yet another leap in the history of human illumination. In recent years Japan's "Light 21 program," United States "the next generation of lighting program," the EU "Rainbow Scheme", South Korea "GaN semiconductor light-emitting plans" and other government programs and so forth. Semiconductor lighting the face of tremendous business opportunities and development prospects of countries around the world to step up legislation to encourage the use of energy-saving light sources. European Union, Canada, Australia and the United States from the 2009,2010 and 2020 respectively, began to ban incandescent bulbs. The data show that in 2008 the application of the global LED market will grow from 12.5 billion in 2004 to 500 billion dollars. China is the world's light source and Lighting Production superpower, in 2006 industry sales of 160 billion yuan, mainly in the low-end products, only 18% of the world market, big but not strong. Development of semiconductor lighting and enhance the international competitiveness of industry is significant. To this end, China in October 2003 launched the National Semiconductor Lighting Project, the establishment of National Semiconductor Lighting Project Management Office, through policy guidance and incentives to promote domestic LED industry and lighting industry. Present, technological innovation and application of LED product development capabilities gradually improved the reliability of the device become more prominent position, test methods and standards Approaching, all of which are marked the LED industry has entered a new stage of development. After 30 years of development, China's LED industry has taken shape, including wafer production, chip preparation and packaging, and application of LED products, including a more complete industry chain. Sharon Wu further explained that "under the Ministry of Science," Eleventh Five-Year "Plan 863, the state in new materials technology," Semiconductor Lighting Project "The total financial investment 350 million yuan. From the general situation, the project made a good start, as a whole smoothly, some issues ahead of schedule milestones. 100 lm / W LED manufacturing technology milestones ahead of schedule, significantly improve enterprise efficiency, already has the capacity for sustainable technological innovation. As of November 2007, the project undertaking unit has applied for patents 241, of which 152 applications for invention patents, foreign patent applications for 17 projects to promote industrial investment of nearly 2 billion yuan. " According to statistics, in 2007, the National LED display market to reach 72 billion, 50 billion yuan in 2006 was 44%. LED chip production in China in 2007 reached 1.5 billion, compared to 10.5 billion yuan in 2006, 43%; 2007, China's LED packaging production to 168 billion, representing 14.8 billion in 2006, up 15%. LED output from 66 billion in 2006, an increase of 24% to 82 billion, of which high-brightness LED output value reached 12.0 billion, accounting for 71% of LED sales. Application products in China in 2007 has more than 30 billion yuan output value, has become a full-color LED display, solar LED landscape lighting applications, the world's largest producer and exporter, the emerging semiconductor lighting industry is taking shape.
