LED will cause a revolution in lighting has no doubt. Although the product on the market and many, but must face is the key technology is to be a breakthrough," edge lace results" is the state of the industry, LED lighting products to enter the market truly still has a long way to go. Both the national semiconductor lighting project, or" ten city lights" demonstrative project, industry technology innovation strategic alliance, the purpose is to promote the development of this emerging industry, to seize the commanding height of competition --
Prospect
Not just a lamp to replace another lamp
LED in China has much room for development, from the Ministry of housing and Urban-Rural Development Secretary Chou Baoxing cited the following three groups of numbers to find the answer: A, China had a total of 657 City, municipal lighting only municipal road lamps have 17740000 lights, each year will grow 1500000 around two, I; each year, new building of 2100000000 square meters, and each building unit at least 20 lamp," Twelfth Five-Year Plan" period, 36000000 sets of housing guarantee there will be 500000000 to 600000000 light application potential, light is the two building lighting, if 30% using the LED lighting, it can save about 100000000000 electrical degrees; three, there are currently nearly about 20000000 households with power shortage, if these households use solar and LED integration, instead of big power grid, it can save about 50000000000 degrees.
" Just look from these three respects, LED will have a very broad market, LED is a power of the main battlefield." Chou Baoxing said. Our country is in this industry layout is already started. Ministry of science and technology in 2003 launched the" national semiconductor lighting project", come nearly 10 years, through 863 plan, plan to support projects such as the continued investment, semiconductor lighting technology significantly improve, formed upstream materials and chip preparation, midstream, downstream device package of integrated application of relatively complete industrial chain and innovation chain. And a complete industrial chain has become China's LED industry advantage.
" Semiconductor lighting brings us not only a lamp to replace another lamp", vice chairman of the CPPCC National Committee, Ministry of science and Technology Minister Wan Gang said," LED is widely used in many areas, will give us life and bring a lot of influence city."
China's current incandescent lamp 1000000000 lamp, lighting energy consumption accounted for the total electricity consumption 1 / 6, with" out incandescent lamps roadmap" promulgated and implemented, the country will publish subsidy policies to promote the development of LED lighting applications, is expected in 2015 China LED lighting market size will reach nearly 100 billion dollars. Although the current LED industry development is not everything is going smoothly., but a huge lighting business, still attract each capital with hitherto unknown speed go into action without delay.
Demonstration
Not only is the 37 city and 400000000 electrical degrees
By the end of 2010, the whole nation already had 81 city installed over 500000 LED street, although still only accounts for 9% of the total number of these city lights, but as a burgeoning industry, it is really a great progress. This is inseparable from the" ten city lights " drive.
In 2011 September, 37 pilot city survey: Currently, pilot city concentrated near 4500 semiconductor lighting company, the total output value of about 140000000000 yuan.
With the increasing input of semiconductor lighting technology, system integration technology research and development is strengthened ceaselessly, rate of technical progress is accelerated apparently. Some of the early problems through the optical design, cooling and other technology integration, some key technologies are solved, the domestic power type LED chip has the branch stem road lighting and interior lighting has been applied.
Upstream of the chip has been China's LED industry weaknesses, but also the core of R & D, after a demonstration project to promote China's chip, homebred change rate increased from 29% in 2008 to 68% in 2011; large power chip industry light efficiency reached 120 LM / W; with independent intellectual property rights of the silicon substrate to power the chip industry light effect reached 100 LM / W; power type white light semiconductor lighting package near the international advanced level; downstream applications and international technology level is basic and synchronous, indoor and outdoor functional lighting light effect has more than 80 lumens / watt; these indicators have been close to the international advanced level. Homebred chip, device and control system integration application of Yu Guoqing 60 anniversary of the Tiananmen a large screen and a" Renaissance" htc flyer tabletNational Grand Theatre screen performances, and achieved good results. After the operation of the market, product reliability, service life, lighting design and integrated application has made great progress.
The international financial crisis has affected China's export trade, some of the traditional industry in a certain range of decline. But in" ten city lights" drive, national semiconductor lighting applications market development, industrial technology has improved, cost can be reduced, and the foreign products compared with the relative competitive advantage. According to preliminary statistics, at present, 37 pilot city has carried out more than 2000 demonstration projects, application of LED lamps more than 4200000 light years, saving more than 400000000 degrees. Not only that, according to local planning," 925" during program implementation of the demonstration project will exceed 7000.
The Ministry of housing and Urban-Rural Construction issued the " Twelfth Five-Year Plan" city green lighting program compendium, compendium puts forward in the "12th Five-Year Plan", the city green lighting and LED promotion should have a great jump. Industry insiders predict," 925" is the city lighting transition five years.
