LED illuminates the future with green

Great temptation semiconductor lighting has so many countries full of optimism about the future of the lighting field, governments around the world have put into practice. American Energy Department predicts that by 2010, the United States will have the incandescent lamp and fluorescent lamp 55% is replaced by semiconductor lighting, saving 35 billion dollars every year. The United States has launched a national semiconductor lighting program, the EU launched the Rainbow program, Japan launched the twenty-first Century light plan. The Japanese government made it clear that in 2006 it is necessary to use a large number of semiconductor lighting to replace the traditional incandescent lamp.

Chinese lighting is the world's largest manufacturing country, with a huge lighting industry and lighting market. At the same time, China has overcome the technical difficulties of high-power light-emitting chip, semiconductor lighting industry significance and immeasurable value. By the Ministry of science and technology and more than a dozen local governments jointly implemented the national semiconductor lighting project has also started. In June 2003, China set up a "National Semiconductor Lighting Project Leading Group", which was represented by the Institute of semiconductors and physics, Peking University, Tsinghua University and other research institutes, actively involved in the field of research and development of the third generation of semiconductor materials, technical achievements transformation.

Since the end of the 1960s by the Chinese Academy of Sciences Changchun Physics Institute successfully developed LED (light emitting diode), to 2004, China has about 3500 more than the LED of all types of enterprises, employees more than 50 people, with an annual output reached more than 40 billion devices, the size of the market has more than 30 billion yuan. At present, the production has been formed from epitaxial chip preparation, integrated device packaging applications such as a complete industrial chain, the country engaged in the semiconductor light-emitting diode devices and lighting system production scale of more than more than and 400 enterprises. China has a large number of middle and low grade LED products in the market, such as display, traffic signal and so on.

In policy, held in May this year, China green lighting International Conference and the Sixth International Conference of efficient lighting made it clear that the "11th Five-Year" period, the national development and Reform Commission will focus on public facilities, hotels, commercial buildings, office buildings, stadiums, residential buildings in the promotion of efficient energy-saving lighting system. The state will also strictly market access to lighting products, not up to the mandatory energy efficiency standards for the production of products may not be sold, not up to the construction of energy-efficient lighting standards shall not start construction. The state will establish an incentive mechanism to speed up the promotion of efficient lighting products, research and development to encourage efficient lighting products, the use of fiscal and tax policies.

Scientists predict, although replaced by semiconductor lighting energy-saving lamps, China into thousands of households may also need a few years or even longer, to landscape lighting, outdoor big screen, small toys, flashlights, Christmas lights, people have reason to believe that LED will brighten everyone's room, so as to change our life.
