WHEN night falls in the Sunny Valley of the Expo Boulevard, a bitmap picture of 16 million colors lights up with rotating hues.
The Shanghai Ecological Home has an astounding lighting system, but there isn't a single standard light bulb inside the building.
The "Magic Box" in the State Grid Pavilion awes audiences with a 720-degree visual experience via a hexagon-shaped screen.
For LED lighting development, the World Expo Shanghai is considered "ground zero" for the domestic LED industry, and several Minhang private companies were among the first to get involved on the ground floor.
That gives the district a "first-strike" advantage, officials said.
The District Science Committee is in talks with the Shanghai Semiconductor Lighting Project Center, hoping to establish an industrial base of LED production in Minhang.
LED, or light emitting diode, technology provides a host of advantages, including rich colors, easy controls and quick response.
It has wide applications in signal lights, background lighting, ordinary household lighting and digital screens.
The entire Expo site is utilizing more than over 1 billion LED chips, including 80 percent of the night views.
Walking around in the Expo site at night, in addition to the four pavilions along the central boulevard and Urban Best Practices Area, one finds many lit plazas, river bank scenes flooded with light, signs and intelligent directional signs.
It's a world full of LED technology.
"It's a brand new industry, and most leading enterprises of this industry are located in Minhang," said one official of the District Science Committee.
"In recent years, these companies have shown sales growth of 30 percent a year," the official adds.
"For those involved in Expo, the experience will not only bring them sales and advertising benefits, but also a perfect opportunity to improve their technology."
Wang Lizhong, general manager of Sansi Electronic Company, noted, "In the past, LED technology was aimed only at commercial market, such as outdoor advertising.
"But now Expo has greatly expanded the possibilities for expanded applications."
Sansi is behind Expo projects valued at 128 million yuan (US$18.8 million), including the background screen at the Expo opening ceremony, the LED screens at the State Grid Pavilion and other 108 information screens all over the Expo site.
The company is preparing to establish the world's biggest LED system lab at their factory in Shuying Road.
Compared with traditional lighting systems, LEDs have a great advantage in energy savings, consuming only half the power of a standard light bulb and lasting five times longer.
They are considered the future for household lighting.
Last October, Shanghai Longguang Shenjing Lighting Technology Corp, which installed LED lighting in the popular Shanghai Ecological Home in the Urban Best Practices Area, applied the technology to lighting in a Guanghua City neighborhood.
They installed over 30 kinds of their LED lighting facilities in the neighborhood, saving about 33,000 kilowatt-hours of power every year.
"Now the biggest obstacle to LED development is the price," said Xie Jinchong, the general manager of Longguang Shenjing."
Many residents in Guanghua City called us and wanted to install an LED system in their homes after our experiment was implemented, but when we told them the price, they lost interest."
Xie added, with an optimistic note, "Given the rapid development of LED technology, I believe within four or five years, the price of LED lighting will drop to the level of standard efficient lighting."
