Semiconductor lighting: the release of green light

The basic components semiconductor white light source for LED (light emitting diode). Experts said that this kind of lighting products as a new generation of electric light after incandescent lamp, fluorescent lamp.

LED is an applied voltage by excited electrons emit light and optoelectronic semiconductor components, known as the green light source, has the advantages of small volume, low calorific value, low power consumption, long service life, fast response, environmental protection, waste Recyclable, good economic and technological value and market prospect.

LED can make brake lights, taillights and direction of the light, but also can be used for lighting and lighting instruments inside the car, it is in shock resistance, energy saving, long service life than incandescent lamp is particularly evident. Using the main brake lights, much faster than the 140 millisecond of the incandescent lamp, is only about a factor of 60 ns (~ 1 ns is equal to about 1/1000000000 seconds), which will increase the safe distance from 4 to 6 meters.

White LED power, the global energy crisis, in order to save energy, the white LED is a trend. Statistics show that in 2003 the global white LED market size of $270 million.

The application of semiconductor LED market is very wide, a mobile phone, automobile, traffic signals, outdoor billboards and lighting market is promising, if white LED price increase, the mature technology of mass production, the most potential lighting market. The lighting market is limited by the brightness and price issues, but also to the next 5 to 10 years to mature.

Professor Liu Deming of Huazhong University of Science and Technology for semiconductor light emitting diode array and semiconductor fluorescent lamp "patent, solves the key technology of high luminous intensity and white light spectrum expansion, has laid a good foundation for the semiconductor white light source lamp series products industry.

Wuhan Optics Valley planning venture investment company of semiconductor lighting industry production base, to establish the covering LED wafer, chip, package, application and development of a complete industrial chain. The project plans to invest 2 billion yuan, after the completion of the investment income will reach RMB 3 billion yuan.

The first semiconductor lighting industry project base has been implemented. Last year, Optics Valley Venture Capital Co., Ltd. and Hongkong long lung investment company established a joint venture in Wuhan, Optics Valley Electronics Co., Ltd., a total investment of 100 million yuan, this year's total output value is expected to reach more than 300 million yuan.
