As one of the country's five major semiconductor lighting engineering industrialization bases, Shanghai has initially formed a relatively complete LED industry chain, which constitutes a green lighting industry cluster with Zhangjiang Hi-Tech Park as the core and Radiation Jiading, Songjiang and Yangpu. As of the end of last year, Shanghai has 105 LED-related patents, and has established more than 100 national, industry and internal standards for the optical industry.
From the Bund to the Donghai Bridge, a “future light source†called LED is also the “energy pioneer†of the city while playing the night in Shanghai. The reporter learned from the "4th China International Semiconductor Lighting (LED) Forum and Exhibition" that was opened yesterday that by 2010, Shanghai's landscape and public lighting will be sung by LED "Protagonist", when Shencheng is expected to save 1 billion a year. The kilowatt-hour electricity is equivalent to the total amount of electricity used for lighting in a small and medium-sized city.
The LED light is not the "old face" of the filament plus the bulb, but a solid-state light source made of a semiconductor chip. It uses electronic movement to illuminate and directly converts electrical energy into light energy. The conversion efficiency is as high as 68%, which is more than 5 times that of incandescent lamps. Therefore, the power consumption of LEDs is only 1/10 of that of conventional bulbs, and its service life is 100 times. It is estimated that if one-third of the country's traditional lighting is replaced by LEDs, a Three Gorges hydropower station will be saved each year.
The night and the more beautiful night Shanghai and LED can be described as "sentimental." Under the LED embellishment, Shanghai's iconic landscape "Oriental Pearl" consumes only 70 watts per spot, which is nearly 75% less than the original incandescent lamp. Wujiaochang's new landmark "Eggs" is embedded with a strip of LEDs 5 cm wide. It disappears during the day and shines into the night, winning the praise of the public. Incredibly, the 1.42 million light-emitting points distributed on the steel frame of more than 10,000 square meters add up to 80 kilowatts of electricity per hour.
Recently, there are two large-scale events and LEDs. The closing ceremony of the Special Olympics will be supported by LEDs. The outer membrane structure of the 2008 Beijing Olympic Games swimming pool "Water Cube" will be multicolored under the LED background. through. At present, the project is being openly tendered nationwide, and Shencheng enterprises have joined the competition.
Behind the hustle and bustle of the city's night scene is the inexhaustible driving force of technological innovation. As one of the country's five major semiconductor lighting engineering industrialization bases, Shanghai has initially formed a relatively complete LED industry chain, which constitutes a green lighting industry cluster with Zhangjiang Hi-Tech Park as the core and Radiation Jiading, Songjiang and Yangpu. As of the end of last year, Shanghai has 105 LED-related patents, and has established more than 100 national, industry and internal standards for the optical industry.
It is reported that in the next few years, Shanghai enterprises will focus on the key technologies of high-power white LED industrialization, reduce production costs, improve luminous efficiency, and let LEDs truly enter the homes of ordinary people. As one of the 12 strategic products developed by Shanghai's “Eleventh Five-Year†science and technology plan, LED will surely become one of the highlights of the 2010 World Expo.
