LED source represent the general trend can not be stopped

Late on January 9, 2005, Pearl River bank beautiful ambilight. After the renovation of the Guangzhou City, a hundred years old - SOUTHERN BUILDING reopened.

In the building facade facing the Pearl River, with countless lights glow. With the brightness of the lights, colors, patterns of different changes in the night sky out of 999 different patterns, attracted thousands of people stopped to watch. The night of the Pearl River become one of the most brilliant landscape. And so after the rebirth of SOUTHERN BUILDING so shining is the semiconductor light-emitting diode technology, also known as LED. SOUTHERN BUILDING has thus become the first outer side of the Pearl River, the use of the fifth generation of LED lighting technology.

LED technology from the boudoir to the market

The construction of the SOUTHERN BUILDING lighting renovation project is the Beijing light spring Technology Co., ltd.. The company is responsible for the wide bandgap semiconductor research center of Peking University. The technique is based on the National 863 project of the wide band gap semiconductor research center of Peking University.

After three years of in-depth study of the LED technology industry promotion, the project team has made the performance indicators and yield of the lighting products has been greatly improved.

In 2000, the center is based on scientific research, and has established the Shanghai Beida blue light Technology Co., Ltd., specializing in the production of blue chip LED. In 2004 with the semiconductor Institute of Chinese Academy of Sciences jointly established the Beijing Ruiyuan solid lighting technology Co., Ltd., the production of high power and high efficiency LED chip technology industrialization.

Both companies are engaged in the production and manufacture of core. As the focus of high-tech world competition, packaging technology of white LED has been in Beijing Baolong Photoelectric Technology Co Ltd transfers.

Thus, the transformation of scientific and technological achievements of Peking University wide bandgap semiconductor research center of several companies, has attracted a total of 100 million yuan of social capital, technology transfer shares accounted for over ten million yuan, the formation of semiconductor white light lighting industry complete industry chain.

A year to save a total of Three Gorges Power Station

Internationally, in this field already smoke. Japan in 1998, the United States in 2000 launched the national semiconductor lighting plan". China's 2001 863 plan project, in June 2003 launched an emergency national semiconductor lighting project".

According to the project of the University of North wide gap semiconductor research center Professor Zhang Guoyi introduction, all this is because the semiconductor lighting technology has the advantage of traditional lighting can not match.

It is low power consumption, has a strong energy saving effect. Expected white LED lighting power consumption is equal to 1/8 of the brightness of the incandescent lamp, fluorescent lamp of 1/2. Zhang Guoyi and we calculate a bill, if the use of LED to replace our current fifty percent of the traditional lighting, the annual savings of electricity, is the sum of the Three Gorges power station. Its energy efficiency is considerable.

Reduce the use of electricity, you can build a small power plant, reduce carbon dioxide emissions, to prevent the greenhouse effect, but also conducive to our country to better fulfill the commitments of the Kyoto protocol. In order to reduce the carbon dioxide emission rights on energy distribution, industrial structure and economic development and the impact of restrictions. In addition, the traditional incandescent mercury pollution problem, LED can easily solve.

Change the traditional concept of lighting

LED is also a kind of green light source, it has no stroboscopic, no infrared and ultraviolet radiation, and the degree of light color, these are incandescent and fluorescent lamps will never reach.

As a new type of lighting technology, LED has the characteristics of small size, long life, flatness, strong design and so on, which can change our lighting concept to a great extent. So that we can free from the traditional point, line light source, to achieve the free layout of lighting.

Zhang Guoyi said that at that time, people can according to the different purposes of the room, the design of different light modeling. Even in the bedroom through the light to simulate the feeling of sunrise and sunset. Can also be designed according to their own mood different lighting effects.

In addition, because of the use of LED when the DC voltage is 2 5V, and use solar energy to generate electricity is easy working voltage up to LED, so LED is especially suitable for combination with solar energy compared with traditional lighting technology.

It is understood that the United States has begun to wind, solar, LED combined with the three residential, office buildings, such as refrigeration, heating and lighting. This new attempt can maximize the use of resources. If we can successfully promote the economic and social benefits will be achieved.

Thus, the LED industry has great potential for development. Not only that, but it can also promote the development of semiconductor manufacturing and raw materials preparation and other related industries. Experts predict that the LED as a lighting source, like the transistor to replace the electronic tube, the trend, unstoppable.
