As the world entered the “post-crisis” era, to find and cultivate new economic growth point and to develop the strategic of new industries,become the most important means to seize the strategic high point in this new era and new round of the world.For China, the development of strategic and emerging industries, not only is our focus on the current crisis of expediency, it is future-oriented, focusing on long-term major strategic decision. LED Lighting is one of the few semiconductor that we gradually mastered the core technologies with the prospects of market demand, availability of resources, low energy consumption, driven coefficient, employment opportunities, comprehensive benefits and good features of the strategic new industries.It not only brought a light in the history of following the incandescent , fluorescent lights and a light source after the revolution, and is an important way to energy conservation, the development of low-carbon economy will play a more important role.
Semiconductor lighting is an important contribution for energy saving, low-carbon economy.
At present, LED light effect has been higher than traditional lighting and display lighting, shows a superior energy-saving effects, such as traffic signals, lighting, landscape lighting and other special areas of energy efficiency above 80%; compared with traditional lighting, functional lighting such as LED street lighting could be saving more than 30%, tunnel lighting can save 40%, LED indoor down light , lighting and other lighting products to replace traditional halogen lamps , fluorescent lamps can save 30% to 50% In 2009 years, the ‘ City of ten thousand ten ‘pilot demonstration and application projects (hereinafter referred to as’ City of ten thousand ten’) is driven by the domestic technological progress significantly faster. Current domestic power type LED chips have been in some branch of road lighting and indoor downlights, spotlights on the lighting applied.Through the optical design, thermal, drive technology integration such as indoor and outdoor lighting luminous efficiency function for more than 80lm / W. According to the 21 pilot cities in the preliminary statistics, as at present, more than 500,000 street lights , tunnel lights, solar LED street lights, LED fluorescent lamp, downlights, spotlights, dance lamps and other products are demonstration applications, more than 100 million kwh of electricity. In addition, the demonstration project, led by the Olympic Games, Shanghai World Expo and Guangzhou Asian Games in addition to extensive use of LED landscape lighting, indoor lighting and some roads will also be demonstration and application of semiconductor lighting products.
According to estimates, the luminous efficiency 75lm / W of LED lamps full life cycle energy consumption (240 kWh) is much lower than the incandescent lamp (1505 kWh), also lower than the compact fluorescent lamps (327 kWh), energy consumption has been the availability of resources and low.Meanwhile, LED is not fluorescent, energy-saving lamps and existing LCD TV, LCD backlight with cold cathode fluorescent lamp (CCFL) mercury problem, you can significantly reduce the environmental pollution of waste lamps, and LED lamps with low voltage DC power supply, no infrared, ultraviolet radiation, is truly green and healthy lighting.
2009 total 3.6506 trillion kwh of electricity, lighting, electricity about 4300 billion kWh, accounting for 12% of the total electricity consumption, accounting for 5.9% of energy consumption, and 5% annual growth rate of 10%. According to our experts predict that 2015 will reach 600 billion kwh electricity for lighting (annual increase of 3% ~ 5%), LED lamps light efficiency can be achieved 120lm / W, LED lighting, with 20% of the lighting market, each year 100 billion kwh electricity conservation can reduce CO2, SO2, NOx, dust emission of 1.5 million tons, 100 million kilowatts can be little build 21 power plants to reduce 30% of the new power station (2015 is expected to add 100 kilowatts power about 63).Expected in 2020, will reach 720 billion kwh electricity for lighting, LED lamp luminous efficiency will reach 150lm / W, 50% into the lighting market, the annual saving 340 billion kwh, 100 million kilowatts can be little build 73 power stations, By saving lighting do not need to add power plants in China.
