    The green on international lighting source LED lamps and lanterns development trend

    As people strengthening of environmental protection consciousness, traditional lighting equipment of high power consumption sex and waste pollution, which has the attention of governments, invest in a lot of money, manpower and material resources development new environmental light source. And a "green," said the LED lighting source, due to its unique energy saving, long life and free maintenance, easy to control, environmental protection and other characteristics, already became the various countries' positive development direction. According to information, semiconductor lighting industry international in recent years to keep the growth rate of 40% in 2008, and is expected to global light emitting diode (LED) market will reach $5.6 billion. Facing the semiconductor illumination great business opportunity and inspiring development prospects, countries all over the world have action, Japan, the United States, the European Union, South Korea and other countries have expensive, launched semiconductor lighting plan.


    Japan in 1998 in the world to take the lead in the 21 st century implementation "lighting" plan, aims to use the long life, the more thin lighter GaN efficient blu-ray and ultraviolet LED lighting technology makes the energy efficiency of the two times for the traditional fluorescent lamps, reduce carbon dioxide produced in 2006, and with white leds completed 50% of the traditional lighting lighting alternative. The plan by the Japanese metal r&d center and new energy industry technology development institutions to initiate and comprehensive organization, participating institutions including four universities, 13 companies and an association. The whole plan of the budget for 6 billion yen. From 1998 to 2002, is the first issue of the 5 billion yen investment target, at present has already been done. Now, Japan is the implementation of the second phase of the project, plan to 2010, LED the luminous efficiency of up to 120 lm/W.


    The United States "semiconductor lighting the national research project" by the U.S. department of energy, plan formulated with 10 years time, investment $500 million to develop semiconductor lighting, participants include 13 state key laboratory, the company and the university. Implementation of the purpose of the program is to make the United States lighting source in the future market competition, ahead of Japan, European and South Korea and other competitors. Schedule of the node is, 2002 20, 2007, / W lm 75 lm/W, 2012 150 lm/W. From 2000 to 2020, the United States semiconductor lighting plan is expected to get the following results: the effect of total and save potential will be reduced from 258 million tons of carbon of pollutants discharge; 133 a new power stations built less; It is estimated that by 2010, 55% of the incandescent light bulb and fluorescent lights replaced by semiconductor; By 2025, solid state lighting source use will make illume to reduce half a year, saving electricity amounted to 35 billion dollars; Cumulative saves the financial spending 115 billion dollars; Form an annual production value of more than $50 billion in semiconductor lighting industry market; Bring high quality 1 million hundreds of thousands of millions of jobs.
