Life expectancy is 100 times faster than traditional light bulb LED new light source

The light source revolution in the world is accelerating, called light emitting diode (LED) light source "model, have fully demonstrated their energy" gift ", more and more special lighting in the field of favor. LED lantern has been identified in the current special olympics closing ceremony, the 2008 Beijing Olympic Games swimming pool "Water Cube" building lighting is open tender, 23000 LED companies have joined the competition. Reporters learned from the Municipal Science and Technology Commission, due to the two key technical problems were solved in advance, high brightness LED is expected from the beginning of the year after the massive march into the general lighting market, lighting up the daily lives of 23000 people.

Energy saving master

According to the information provided by the Shanghai semiconductor lighting Engineering Research Center Engineer Li Shuzhi, Shanghai's total electricity consumption of 12% ~ 15% of lighting electricity, if the use of LED lighting to replace the bulb, it can save about 70%. Ordinary incandescent lamp power is 40 ~ 60W, and the LED lamp is only 3 ~ 6W, and the life span to 30 thousand ~ 50 thousand hours, although the global LED lighting price expensive than ordinary light, but these additional costs will be 3 ~ 5 years back.

At present, the cost of LED is reduced at an annual rate of 20%, is expected to start next year, for general lighting LED lights will increase significantly.

High quality new light source

Replace the neon lights, landscape lighting energy-saving 70%; replace the incandescent lamp, the traffic lights on such 80%; the luminous efficiency has been higher than expected in 2010 will be more than incandescent lamp, fluorescent lamp, the general lighting in the world's total electricity consumption 15% ~ 20%, the energy saving effect will be more obvious. Countries around the world are generally optimistic about the prospects for the development of LED lighting. The United States, European Union, Japan and South Korea in recent years, LED have to tailor the promotion plan and entrusted with the task.

In agriculture, LED and solar cell can be made to plant light: during the day, let the plants absorb sunlight enjoy the nutrition, night use the day to collect solar energy, let LED light plant required wavelengths of light, increase crop yield. In addition, the LED can be adjusted into a cold light source does not emit light, used in underwater lighting, not moss.

At present, LED has been widely used in landscape lighting, architectural lighting, traffic lights, road lighting, large LCD TV backlight and automotive lighting, etc.. Many of the buildings around us, it has been adopted by the LED lamp, such as the Bund, the Oriental Pearl, the International Conference Center, Wujiaochang Donghai Bridge, Chongming eggs, Qianwei village and so on, have already or plan to implement the semiconductor lighting demonstration project. It is reported that the city will soon be in the use of LED landscape lighting in the organization of the top ten selection.

Solid state light source using semiconductor chip as material. 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.
