SHANGHAI plans to use a bigger range of LED devices - from plasma TVs to crop planting - to reduce energy consumption, city officials said yesterday.
The plans are based on the development of the core technology of light-emitting dioxides or LEDs, a task within the city's scientific 2020 development scheme, officials of the Shanghai Science and Technology Commission said.
"We are trying to use LEDs to improve people's lives in a variety of ways," Guo Yansheng, director of the commission's Hi-tech production department, said at the 2008 Shanghai International LED Industry Technology Exhibition that opened yesterday at ShanghaiMart. The show will end tomorrow.
At the exhibition, the Shanghai Research Center of Engineering and Technology for Solid-State Lighting displayed its latest LED products including plasma screens, car lights and crop planting devices.
LED is an energy-saving lighting semiconductor that has great market potential over the next decade because LEDs consume only about one 10th of the power of an incandescent bulb to produce the same amount of light.
An electricity meter showed a new plasma screen made from LED uses just 50 percent of the power needed by a conventional LCD screen. The LED screen also gives a better picture although it costs about 2,100 yuan (US$300) more. Yang Weiqiao, a researcher with the center, said the center is now cooperating with SVA Group - the city's chief producer of electronic and information devices - to industrialize the new screens.
"Hopefully, the new screens will enter the local market by 2010," he said, noting that the technology was on a par with international competitors and they were working to reduce the cost.
As well as TV screens, the center also showed other LED products including car lights and lighting to produce artificial photosynthesis to stimulate crop growth.
