Lighting revolution semiconductor light-emitting diode light Global

The development and progress of human civilization is closely related to lighting. Thousands of years ago, when the first torch was lifted, the first revolution in the field of illumination began. After thousands of years, 1879 Edison invented the first incandescent lamp, opened the curtain of modern civilization of mankind, it is mankind lighting the second revolution; now, a new solid-state light-emitting device, semiconductor light-emitting diode (LIGHTEMIT, tingdiode, LED) will be human lighting into a new historical period. Because of the most effective energy saving and environmental protection, semiconductor lighting has been called the third revolution in the field of lighting.

The Central Organization Department, the Central Committee to head, the fifth batch of Inner Mongolia, service group, vice mayor of Hohhot City, Dr. Fang Zenan, at the Inner Mongolia University of Technology recently published in the above speech, entitled "semiconductor light Global: Lecture third lighting revolution", he will own by up to half the time from the investigation results to emerge in its totality. A nearly 500 young students diligently strive after.

According to Dr. Fang introduced, semiconductor lighting has a high degree of energy saving, environmental protection, long life and small size, low heat, easy to control and so on. Since the end of last century and the beginning of this century, the United States, Japan, Germany, South Korea and China's Taiwan and other countries and regions, has invested heavily in research and planning and industrial development. Japan in 1998 formulated the "twenty-first Century lighting plan", the United States in 2000 to develop the "next generation lighting plan" has been included in the energy bill, Germany established the world's most advanced chip production line, made of LED new energy-saving long-life lamp is a new target for them. The European Union's "Rainbow Project" was launched in July 2000 to promote the application of white light led through the EU grants.

Dr. Fang believes that 80% of China's electricity generation for thermal power generation, dust, CO2 and SO2 emissions of more than 15 million tons per year. Caused by environmental pollution, increase the greenhouse effect, coupled with a large number of fluorescent lamps and other lighting appliances, mercury pollution has become a problem. It is of great significance to promote the development of semiconductor lighting. According to the "big sixteen" economic development goals, by 2020, the national generating capacity of about 850 million kilowatts. At present, China has installed capacity of 350 million kilowatts, the need to add 500 million kilowatts. From the current resources in our country, according to the proven reserves of hydropower resources and natural gas and coal as the fuel of the maximum installed capacity of thermal power calculation, there will be 40 million kilowatts gap. China's annual lighting power consumption of about 300 billion degrees, if the general use of semiconductor lighting, in accordance with the calculation of electricity saving of 30%, the annual energy saving of 100 billion degrees, equivalent to a Three Gorges power station.
