Bright Expo boost Shanghai LED industry

The opening ceremony of the World Expo that is 300 meters long and 30 meters high, the world's largest outdoor LED display, provides a stunning visual feast not only to a global audience, but also in Shanghai has become a showcase of LED technology.

World Expo this year to provide a broad platform for LED technology embodies the focus. It is understood, LED landscape lighting technology in Hannover World Expo and World Expo Aichi has been small, but for the first time a wide range of application in our country, also is the first time. In addition to the main venue of the opening ceremony of the World Expo stage background, including LED full-color display Chinese Pavilion, pavilion hexahedron box and oil on the museum wall. According to preliminary calculations, a total of 1 billion 500 million LED chips are used in the Expo site, while about of the indoor lighting source of the Expo venue is LED.

LED chip in the Expo Park in the indoor and outdoor lighting, landscape decoration, signage, information display, the entire park has become the world's most concentrated demonstration of the application of semiconductor lighting technology. Fudan University professor Fang Zhilie participated in the research work of LED lighting in Shanghai, World Expo. In his view, the Shanghai Expo LED lighting centralized application shows that Shanghai, World Expo is likely to open a semiconductor lighting year".

Shanghai economic information committee deputy director Zhu Weihua said, at present, our country has been included in the semiconductor LED lighting in the long-term technology development plan, introduced in September 2009 to promote the "Shanghai electronic information manufacturing industry of high-tech industry action plan" also clearly will focus on the development of LED as a new type of display field. Shanghai as one of the national semiconductor lighting project industrialization base, has been basically established a relatively complete epitaxial wafer production, chip preparation, packaging, integrated application of LED industry chain, especially at both ends of industry chain extension, namely upstream of the LED chip and the downstream application link has certain advantages, is expected to reduce costs in the future, the LED technology to enter the field of general lighting.

It is reported that the Expo Park these LED masterpiece mostly from Shanghai think twice. Founded in 1993, Shanghai has twice is the largest LED display and lighting products professional manufacturers, the main products are lighting and display, the LED display products have reached the first domestic and international advanced level. Since 2002, the company's annual sales increased at an average rate of 30%, the next step will be to build the world's largest LED application research center.

In terms of energy saving, think the R & D department responsible person told the reporter, LED used in the lighting field, in addition to small volume and light weight, fast response time, the power consumption than traditional energy-saving lamp low of 30% to 50%, and the life was less than traditional lamp 50%, can reach more than 50 thousand hours, but also do not like the ordinary energy-saving lamps that produce environmental pollution. But on the other hand, the responsible person also said that although the LED energy saving effect is remarkable, but as the core of the light emitting chip need to be imported from abroad, and the heat dissipation solution the high cost of these two problems, cause now a LED lamp price is almost 3 times than the same type of lamps.

Zhu Weihua said that with the continuous development of LED technology, the application of domestic LED is also maturing, has been from the indicator lights, lights, displays, landscape lighting, to broaden the indoor and outdoor lighting. At present, the application of LED in the field of display has been relatively mature, the application of special lighting in the field of continuous development, in the field of general lighting has just started, there is a huge space for development. I hope to take this opportunity to further promote the LED technology in World Expo, so that it can be widely used in urban landscape lighting and road lighting.
