Shanghai is the advent of every night, a magnificent "landscape light show" will be staged at the Shanghai World Expo: what theme pavilion facade IPL sparkling little stars, outside the walls of the Expo Center exudes quiet elegance white light, the embodiment of the Expo Axis Sun Valley dazzling beautiful movie screen to project the pattern, the Chinese Museum, Cultural Centre, Museum oil set off in the LED light source, appear quite bright ... ...
This "light show" is not only a visual feast, it is a feast of science and technology. Recognized as the fourth generation of lighting technology, the use of light-emitting diode (LED) "solid-state lighting" in the Shanghai World Expo has been fully demonstrated. According to report, the total amount of the Shanghai World Expo LED chips over the 1.003 billion, of which the park Bacheng night lighting with LED technology, the Expo site has become the world's largest LED demonstration area.
Shanghai World Expo is so "love" LED, and LED technology, forward-looking are inseparable. Director of Science and Technology Commission of Shanghai High-tech, semiconductor lighting Guo Yansheng Engineering Research Center, said in an interview, compared with traditional light sources, LED technology is energy-saving environmental protection, control two significant advantages. In terms of energy saving, LED light source technology than the traditional average energy by 60% to 80%. Meanwhile, LED light source under computer control in the formation of different combinations of light and color to achieve a variety of dynamic variation. It is this feature, so visitors to the Expo Hall in the sun, cultural centers, etc. to see a great variety of lighting effects.
Historically, human beings each leap in lighting technology have left footprints on the history of the Expo. Expo 1873 in Vienna, the invention of the motor so that ushered in the electrification of the human era. 1878 Paris Expo, Edison's incandescent light bulb is installed in the Eiffel Tower, the Expo will illuminate the entire translucent crystal. 1939 World Expo in New York and Los Angeles, showing the first practical fluorescent lamps. "Shanghai World Expo may be the first year of human solid-state lighting," Shanghai Gang, general manager of light associated lighting, said his company is the Shanghai World Expo provides a wealth of LED lighting fixtures.
LED technology in large-scale application in the Expo, which makes clear the technology from the people's lives are no longer distant. Guo Yansheng introduced the Chinese Ministry of Science and in 2004 launched "Ten City, ten thousand" program, 21 cities in China to promote LED lighting. At present, Shanghai's municipal building has been extensive use of LED lighting technology. "The government is taking measures to reduce the cost of LED lighting," he said, "I believe that within 3 to 5 years LED can be in every household."
In size, China is already the LED industry, big country, but in China from the international advanced technology, there are still gaps. It is reported that the majority of the Expo LED lighting to achieve a localization, but the LED chip, the majority of imported chips. Shanghai Institute of Technical Physics Institute of Chinese Academy of Sciences Lu Wei pointed out that industry standards are not unified, the Chinese LED industry grow restricting bottleneck. He expressed the hope that the platform through the Shanghai World Expo will further promote the LED industry.
