Shanghai World Expo: “Demonstration Project†for LED Technology Applications
Strolling through the Expo Park at night, the colorful lighting effects provide visitors with a unique "light art landscape". At the 2010 China (Shanghai) International LED Industrial Technology Exhibition and Forum held in Shanghai, experts pointed out that the Shanghai World Expo has become a "demonstration project" for LED technology applications.
According to reports, the "One Axis and Four Pavilions" and the Urban Best Practice Area, which are composed of the Expo Axis, the China National Pavilion, the Expo Theme Pavilion, the Expo Center and the Performing Arts Center, have adopted a large number of semiconductor lighting technologies, and the square landscape lighting of the Shanghai World Expo Park. This technology has also been adopted along the Yangtze River landscape belt, signage and intelligent guidance systems, as well as in various national pavilions.
Xiong Feng, assistant director of the Shanghai Semiconductor Lighting Engineering Technology Research Center, said that the World Expo has become a "concentration demonstration zone for LED technology, creating a new era of LED applications." Taking the Expo Axis as an example, there are more than 80,000 LED lamps in the whole building for centralized and unbiased control. “The whole building is like a transparent giant trumpet, and the hundreds of meters of tensioned film and the Sun Valley are connected into a grand dynamic. The water wave and the light color gradually change on the whole level of the tension film, resulting in beautiful and vivid artistic lighting landscape."
“The most noteworthy is the “Shanghai Eco-Home†pavilion in the Urban Best Practices Area.†Xiong Feng said, “This is the only venue in the entire Expo Park that uses LED technology for indoor and outdoor lighting.†He introduced It is said that with the continuous improvement of LED light efficiency, LED lighting technology can be fully applied to indoor white light lighting, and has many advantages such as energy saving, environmental protection, controllability, etc., which can integrate light with environment and architectural landscape. To achieve the effect of "seeing the light without seeing the light".
Not only the Expo venues, but also the streetlights, buses and other supporting facilities in the Expo Park can also see the application of LED technology. Xiong Feng said that the inner courtyard road of the Expo Park uses nearly 200 LED street lights, which not only has good lighting effect, but also is very energy-saving. Shanghai New Energy Bus has also replaced fluorescent lamps with LED lights, achieving energy saving and no The effect of ultraviolet radiation.
According to preliminary estimates, more than 80% of the nightscape lighting sources in the entire Expo Park use LED technology, and the comprehensive energy-saving efficiency can reach more than 70%. Experts pointed out that LED technology has become the main light source technology for outdoor landscape lighting and decorative lighting. With the continuous development of LED high-power light source and the continuous innovation of lighting art, the demonstration application of the World Expo will occupy the market to a greater extent.
