Expo Park as the world's largest LED demonstration area

When night comes a Shanghai, "the magnificent landscape lighting show will be staged at the Expo Park in Shanghai: the Theme Pavilion facade things flashing the starry light and the Expo Center wall exudes a quiet and elegant white, Sun Valley of Expo Axis incarnation movie screen projected dazzling beautiful pattern, China Museum and cultural center, oil Museum is nestled in the LED light source is dazzling......

This "light show" is not only a visual feast, but also a feast of science and technology. As the fourth generation of the world's leading lighting technology, the use of light-emitting diode (LED) solid state lighting technology in Expo Park, Shanghai has been fully demonstrated. According to the reporter, the total amount of Expo Park Shanghai LED chip in more than 1 billion 3 million, of which the park's 80% night lighting using LED technology, the Expo has become the world's largest LED demonstration area.

Shanghai Expo so love LED, and LED technology is inseparable from the forward-looking. The director of the Shanghai Municipal Science and Technology Commission Director of high-tech semiconductor lighting engineering research center Guo Yansheng said in an interview with reporters, compared with the traditional light source, energy saving and environmental protection, controllable LED technology has two advantages. In terms of energy saving and environmental protection, LED technology than the traditional light source average energy saving 60% to 80%. At the same time, LED light source can be formed under the control of the computer to form a combination of different colors, to achieve a variety of dynamic effects. It is this feature, so that visitors can be seen in the Expo Hall, cultural centers and other places to see a variety of lighting effects.

Looking back at history, every leap in human lighting technology has left footprints in World Expo's history. 1873 Vienna, World Expo, the invention of the electric motor ushered in the era of mankind. 1878 Paris, World Expo, Edison invented incandescent bulbs are installed on the Eiffel Tower, the entire park will be crystal clear. 1939, New York and Losangeles, World Expo, shows the first practical fluorescent lamp. "Shanghai World Expo may become the first year of solid state lighting," said Wang Gang, general manager of Shanghai Lighting Co., Ltd., which provides a large number of LED lighting for the Shanghai expo.

The large-scale application of LED technology in Expo Park shows that this technology is not far away from people's lives. Guo Yansheng introduction, China's Ministry of science and technology in 2004 to start the Ten City million plan to promote LED lighting in 21 cities in china. Currently, Shanghai municipal construction lighting has been a large number of LED technology. "The government is taking a number of measures to reduce the cost of LED lighting," he said. "I believe that within 3 to 5 years, LED will be able to enter the household. "

On the scale, China is already a big country in the LED industry, but in the field of technology, China still has a gap from the international advanced. It is reported that most of the Expo LED lighting to achieve localization, but the majority of LED chips imported chips. Shanghai Institute of Technical Physics, Chinese Academy of Sciences Lu Wei pointed out that the industry standards are not uniform, is a bottleneck restricting China's LED industry stronger. He expressed the hope that through the platform of Shanghai, World Expo, to further promote the development of LED industry.
