Development trend of green lighting source LED lamps in the world

With the increasing awareness of environmental protection, the traditional lighting equipment of high power consumption and waste pollution problems, has aroused the attention of governments, have invested a lot of money, manpower and material resources to develop the environmental protection new light source. And the "green lighting source," said the LED, because of its unique energy saving, long life, maintenance free, easy to control, environmental protection and other characteristics, has become the direction of national development. It is understood that the international semiconductor lighting industry in recent years to maintain the growth rate of 40%, is expected in 2008 the global light-emitting diode (LED) market will reach $5 billion 600 million. In the face of the huge business opportunities and encouraging development prospects of semiconductor lighting, countries all over the world have been in action, Japan, the United States, the European Union, South Korea have invested heavily in the introduction of the national semiconductor lighting plan.

Japan in 1998 in the world's first implementation of the twenty-first Century lighting plan, aimed at through the use of long life, thinner and lighter GaN, blue and ultraviolet LED technology makes the energy efficiency of lighting increased to two times of the traditional fluorescent lamp, carbon dioxide, and finished in 2006 with a white light emitting diode lighting instead of 50% the traditional lighting. The program is sponsored and organized by the Japan Metal Research and development center and the new energy industry technology development agency, which includes 4 universities, 13 companies and one association. The budget for the whole project is 6 billion yen. From 1998-2002, the investment is 5 billion yen in the first phase, has been completed. Now, Japan is implementing the second phase plan, plans to 2010, LED luminous efficiency of 120lm / W.

United States Department of energy, the United States Department of energy, plans to spend 10 years to invest $500 million to develop semiconductor lighting, participants include 13 national key laboratories, companies and universities. The purpose of the implementation of the plan is to make the United States in the future lighting market competition, ahead of Japan, Europe and South Korea and other competitors. The planned time node is 2002 20lm / W, 75lm / W, 150lm / W, /. From 2000 to 2020, the U.S. semiconductor lighting plan is expected to be made the following achievements: the cumulative effects and potential savings will reduce 2.58 tons of carbon discharge of pollutants; few built 133 new power plants; it is expected that in 2010, 55% of the incandescent lamp and fluorescent lamp has been replaced by semiconductor light; by 2025, the use of solid state lighting will make lighting electricity is reduced by half, saving $35 billion a year; cumulative save expenditure of $115 billion; the formation of semiconductor lighting industry market an annual output value of more than $50 billion; bring hundreds of millions of high quality jobs.
