LED energy-saving technology will enter the field of general lighting

In Shanghai at the 2008 Shanghai international LED Industrial Technology Exhibition "upload a message, LED (light emitting diode) lamp luminous efficiency of white has several times in the incandescent lamp, is expected in 2010 will be more than the fluorescent lamp, energy-saving effect will be more significant. The industry said that LED technology is about to enter the field of general lighting, forming a huge industry of tens of billions of dollars. A semiconductor is a new type of solid-state light sources, in particular the lighting field has shown excellent energy saving effect, such as landscape lighting instead of neon lights, 70% energy saving; traffic signal lamp replace incandescent lamp, energy saving 80%. With the continuous improvement of technology, large-size LCD TV backlight, automotive, commercial and industrial lighting has gradually become the main application areas of LED.

The characteristics of low power consumption, long service life, in the face of the global energy crisis and the huge environmental pressures, semiconductor lighting has been recognized as one of the important ways of energy saving and environmental protection, are growing at a faster pace to expand its scope of application of various.

At present, the luminous efficiency of white light semiconductor lighting lamp has the laboratory several times in the incandescent lamp, to 150 lumens per watt 190 lumens per watt, is expected in 2010 will be more than the fluorescent lamp, energy-saving effect will be more significant.

It is estimated that China's lighting electricity consumption accounted for 12% of the total electricity consumption, as long as the current China's 1 / 3 of the incandescent lamp was replaced by LED, the annual savings of electricity for the country of 100 billion degrees.

At present, all countries in the world to seize the commanding heights of semiconductor lighting emerging industries. In June 2003, the Ministry of science and technology, Chinese Academy of Sciences and other units of the joint Beijing, Shanghai and other places to set up the national semiconductor lighting project leading group, Shanghai, Xiamen, Dalian and Nanchang to become the first batch of four national semiconductor lighting industrialization base.

According to the plan, Shanghai will be the core technology for 2020 to master all aspects of the semiconductor lighting industry, the semiconductor lighting application terminal product development with independent intellectual property rights, the formation of the Shanghai green lighting technology industry chain. At present, Shanghai semiconductor lighting industry base has formed a more complete industrial chain from the substrate materials, epitaxy, chip, packaging to the application.

"2008 Shanghai international LED Industrial Technology Exhibition" held on May 9th to 11, organized by the Shanghai semiconductor lighting engineering research center, Japan three Chang Corporation as well as Japan, South Korea and other countries and regions of the LED association. During the exhibition will be held in the industry concerned about the latest trends and advanced technology industry technology forum.
