With the enhancement of people's awareness of environmental protection, the high power consumption and waste pollution of the traditional lighting equipment, has attracted the attention of governments, have invested a lot of money, manpower and material resources to develop new environmentally friendly light source. And the "green lighting source" of the LED, due to its unique energy-saving, long life, maintenance free, easy to control, environmental protection and other characteristics, has become the active development of the country. It is understood that the international semiconductor lighting industry in recent years to maintain a growth rate of 40%, is expected in 2008 the global light-emitting diode (LED) market will reach $5600000000. In the face of the huge business opportunities and encouraging prospect of semiconductor lighting, the world countries have action, Japan, the United States, the European Union, South Korea and other countries have invested heavily in the introduction of national semiconductor lighting plan.
Japan in 1998 in in the world to implement the "twenty-first Century lighting" program, designed by the use of long life, thinner and more light GaN efficient blue and ultraviolet LED technology makes the energy efficiency of the traditional fluorescent lamp two times, reduce carbon dioxide generation, and in 2006 after the use of white LED lighting to replace 50% of the traditional lighting. The program is organized by the Japanese Metal Research and development center and the new energy industry technology development agency and organization, including 4 universities, 13 companies and an association. The overall budget for the program is 6000000000 yen. From 1998-2002, the investment is 5000000000 yen for the first phase of the target, has been completed. Now, Japan is implementing the second phase plan, plans to 2010, the luminous efficiency of lm/W reached 120 LED.
United States "semiconductor lighting national research project" by the United States Department of energy development, plans to use 10 years, investment 500000000 U. S. dollars in the development of semiconductor lighting, including 13 national key laboratories, companies and universities. The purpose of the implementation of the program 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, 2007 75lm/W, 2012 150lm/W. From 2000 to 2020, the United States semiconductor lighting plan is expected to will achieve the results are as follows: cumulative effect and potential savings will reduce the discharge of 2.58 million tons of carbon contaminants; building block 133 new power plant; it is estimated that by the year 2010, 55% of incandescent and fluorescent lamps are semiconductor lamps to replace; by 2025, the use of solid state lighting will enable lighting electricity cut in half, annually saving amounted to $35 billion US dollars; accumulated savings spending $115 billion; the formation of an annual output value of more than $500 billion of semiconductor lighting industry market; bring high quality of millions of jobs.
The EU's "Rainbow plan" was launched in July 2000, commissioned 6 large companies, 2 universities, through the EU grant to promote the application of white light emitting diodes. Hope to achieve high efficiency, energy saving, non use of hazardous materials, the target of natural light through the application of semiconductor lighting.
South Korea "GaN semiconductor development plan" is from 2000 to 2008, by the government invested $472000000, the enterprise invested $736000000 to start. Research projects include LED, blue, green Diode Laser and high power electronic components HEMT three major areas of GaN, respectively, KnowledgeOn, Samsung and LG company responsible for progress management. Hope that the 2008 LED luminous efficiency of 80lm/W.
2003, China's Ministry of science and technology has also launched a national semiconductor lighting project, designed to meet the new lighting revolution, accelerate the development of China's semiconductor lighting technology and industry. China's Taiwan region has also set up a "second century lighting source development plan", and vigorously develop the semiconductor light-emitting diode industry. The project investment of about 6-10 billion new Taiwan dollars, to participate in the 14 enterprises, scientific research institutions and universities, 2005 is the production investment 40lm/W led 100lm / W target in laboratory.
In the face of great temptation of semiconductor lighting market, the world's three major lighting industry giant, Ge, Philips, Oscar Lamm group have also cooperation with semiconductor company, established semiconductor lighting enterprises, and proposed to before 2010, so that the semiconductor lamp luminous efficiency increases by 8 times, and the price was reduced by 100 times. Like leore Ge company, GE Philips company, LumiledsLinghting lighting company, Osram company, Osram company, have invested heavily in the development of its own semiconductor lighting industry, which will undoubtedly accelerate the process of entering the LED industry into the general lighting industry, the semiconductor lighting industry has a huge impact.
