Expo opening LED lighting era to reduce costs is the key to promote

In Expo Park in Shanghai, the large-scale application of semiconductor lighting has become another important interpretation of Low Carbon Expo ". As in 1867 the French Paris World Expo, 1873 Vienna World Expo tower lights gas lamp, incandescent lamp in 1878 France Paris World Expo, Shanghai semiconductor lighting Expo in the realization of the lighting function at the same time, but also become an important showcase project, and enhance the night Expo artistic expression on the whole.

For the first time in urban blocks

In recent years, semiconductor lighting has gradually become the focus of competition in the field of energy-saving technologies. As early as 2000 in Hannover, Germany, World Expo and Japan in 2005, Aichi, World Expo has been part of the use of semiconductor lighting technology, but its application is limited and the scope is very limited.

2010 Shanghai, World Expo, LED chip appeared in the Expo Park of Shanghai indoor and outdoor lighting, landscape decoration, signage, information display and other aspects.

Take "one axis and four Pavilions" as an example, LED is the main way of lighting.

In the lighting design of the Expo Theme Pavilion, the water curtain projection, the combination of solar energy and semiconductor lighting, lighting control technology are adopted to realize the interaction between the theme pavilion and the surrounding environment.

In the north and south facades, aluminum curtain wall out of the hollow hole spacing to square gradually decreasing, the formation of facade texture, lighting design by opening in the bottom plate, placed full-color LED light projection line, a sense of rhythm of space optical elevation. The ecological greening wall of the East and the west is decorated with random arrangement of full-color LED decorative lamps, which reflects the interaction between the Expo and nature.

The shape of a "flying saucer" Expo Cultural Center, more use of the lighting with the intention of architectural design concept, highlight the "space visitors" sense of the future, focusing on the investment performance of "light shell saucer" smooth smooth, with the surface of the shell open circular window and central Huanlang penetrate in the lighting effect, create a with the vigour of the times in Pujiang on the edge of the landmark image. The lighting is mainly through the side wall of light illuminate the window in the lower part of the installation of LED linear circular window and wall, resulting in the light transmission effect. The shell rises outward from the middle, also placed in the ground by LED light to light up.

Expo Center lighting design mainly uses LED light source. Its interior a 2000 square meters, can accommodate up to 600 people in the middle of the conference hall all use LED lighting, to achieve the green lighting technology from the landscape to the practical leap. The Expo Center of the building exterior lighting also uses two types of color temperature linear LED, for internal lighting. Through intelligent control technology, the building facade presents a rich and efficient night lighting effect.

The concern of the Chinese Pavilion, in the appearance of the use of high color rendering of LED cast light lamps to illuminate the main structure of the red, fully demonstrated the museum "China Red" color.

Deputy director of the Shanghai Municipal Economic and Information Technology Commission Zhou Minhao said in an interview with reporters, there are a total of 1 billion 30 million LED chips are used in the Expo Park Expo venues; indoor lighting, by about 80% LED green light, compared to ordinary incandescent lamp energy saving about 90%.

This is the first large-scale use of LED lighting in China's urban neighborhoods, but also the world's most concentrated demonstration of the application of semiconductor lighting technology. Zhou Minhao said.

High cost is still the key to promotion

LED lighting can be used in people's homes, but now the biggest problem is the cost of a little high, compared with the general energy-saving lamps more expensive, may still be used mainly in the decoration. Zhou Minhao introduction, the current lighting, the government is still to promote energy-saving lamps. 2008, 2009 years, Shanghai City, a total of energy-saving lamps to promote the only 10 million. The promotion of the main energy-saving lamps are simple, such as supermarkets to sell energy-saving lamps, relatively simple in the production. In order to solve the problem of energy-saving lamps, the government will give some subsidies in the promotion process.

Zhou Minhao said that the energy saving effect of simple energy-saving lamps are equally impressive, if all 10 million lights, the annual savings of 500 million kwh.

Shanghai semiconductor lighting industry incubator chairman Li Manping believes that World Expo provides a large number of materials and data for the study of light color LED. These are expected to promote LED lighting into the field of home lighting.
