Semiconductor lighting: urban energy pioneer

As one of the five national semiconductor lighting industrial base, Shanghai has initially formed a relatively complete industrial chain of LED, formed to Zhangjiang hi tech park as the core, green lighting group Songjiang, radiation Jiading, Yangpu and other areas of industry. At the end of last year, Shanghai has 105 LED related patents, has developed more than 100 optical industry, national standards, industry standards and internal standards from the Bund to the East China Sea Bridge, called LED "the future light" in the beautiful night in Shanghai at the same time, also be such "pioneer city". Reporters yesterday from the opening of the fourth session of the Chinese international semiconductor lighting (LED) forum "was informed that in 2010, Shanghai's landscape and public lighting will sing" protagonist "by LED, then the largest year is expected to save 1 billion kwh of electricity, equivalent to a year in a small city lighting electricity total. LED light bulb filament is not with "old face", but by the semiconductor chip for solid-state light source materials. It is the use of electronic moving to light, the direct conversion of electric energy into light energy, conversion efficiency of up to 68%, incandescent lamp is more than 5 times. Therefore, the power consumption of LED is only 100 of the traditional light bulb, the service life is its 1/10. It is estimated that if the country's 1/3 of the traditional lighting with LED replacement, will save the next three Gorges Hydropower station. More the more beautiful night night in Shanghai and LED can be described as "soul". In the embellishment of the LED, the Shanghai landmark landscape, the Oriental Pearl each spot power consumption is only 70 watts, saving nearly 75% of the original incandescent lamp. Wujiaochang's new landmark eggs embedded in 5 cm wide strip of LED, hidden during the day, at night shine, won the public praise. It is incredible that the distribution of more than 10 thousand square meters in the steel on the 1 million 420 thousand light-emitting points, the amount of electricity per hour plus up to 80 kilowatts. Recently, has two large event and become attached to the LED - the Special Olympics Closing ceremony will be LED to help out, the outer membrane structure of the 2008 Beijing Olympic Games swimming center "Water Cube" will become colorful transparent in LED background. At present, the project is open to the public bidding, 23000 companies have joined the competition. Behind the bright night view of the city, is an inexhaustible motive force for technological innovation to provide. As one of the five national semiconductor lighting industrial base, Shanghai has initially formed a relatively complete industrial chain of LED, formed to Zhangjiang hi tech park as the core, green lighting group Songjiang, radiation Jiading, Yangpu and other areas of industry. As of the end of last year, Shanghai has 105 LED related patents, the development of more than 100 national standards, industry standards and internal standards of the optical industry. It is reported that in the next few years, Shanghai enterprises will be aimed at the key technology of high power white LED industry research, reduce production cost, improve the luminous efficiency, let LED into the homes of ordinary people. As one of the twelve strategic products in the 11th Five-Year Shanghai science and technology planning focus, LED will become one of the highlights lit in World Expo in 2010.
