into two categories . Light-emitting diode (LED) as a light source of new lighting , known semiconductor lighting , LED lighting referred to as the main semiconductor lighting industry called the LED lighting industry . LED lighting industry chain includes upstream raw materials, equipment ( single chip ) and epitaxial growth ; chip manufacturing midstream ; packaging and product development, production and application of downstream ; supporting industries , including related equipment , accessories and materials. Upstream high technical content, capital investment, massive impact , high profit margins , LED light colors and luminous efficiency and production of LED materials and process-related and upstream accounting for about LED manufacturing costs 70% of the LED industry is extremely important ; midstream technology and capital -intensive sectors , the chip is the most competitive part of the patent , but with a large investment intensity characteristics of the slow effect ; downstream sectors , including development and production of LED packaging and lighting applications , and is most closely associated with the market sectors , technology content is relatively low , the investment threshold is too low , so it is the largest LED industry and the fastest growing areas .
International LED Lighting Industry Status LED lighting industry is in a period of rapid development , the global LED industry can be divided into four regions . First, Europe and America, with general lighting as the main direction , emphasizing high reliability and high brightness products. Second, Japan, the most comprehensive technology , whether it is general lighting , or backlit display , both with strong strength , its direction both general lighting , automotive , mobile and TV. Third, Korea and Taiwan region of China , to the laptop display backlight , LED-TV backlight and phone backlight is the main direction of large shipments , low price , low margin . Fourth, the Chinese mainland , mainly to yellow green , the main outdoor display, advertising screen , lights in the field .
In the domestic industrial policy and international market demand double pull , LED lighting products market in China is also accelerating development. Currently, the global LED production transferred to China , about 50% of the global LED packaging and LED application more than 60% are in China . China has become the world's fastest growing semiconductor lighting industrial area .
Domestic LED lighting industry development policy by virtue of the inherent advantages of energy saving , LED lighting industry has become the green revolution started strong engine , known as the " golden cross point of the new sources and new energy ," continued support of national and local government levels . In early 2006 , the State Council issued the " Long-term Scientific and Technological Development Plan ", the " energy-efficient , long-life semiconductor lighting products " included in long-term planning of the first areas of focus ( energy ) first priority themes ( industrial energy efficiency ) , attracted wide attention at home and abroad ; same year in October , the national " Eleventh Five-Year " Plan 863 "Semiconductor lighting Project" was officially launched major projects . January 10, 2008 , the Ministry of Finance , the National Development and Reform Commission ( hereinafter referred to as the " NDRC " ) jointly issued the " financial subsidies to promote efficient lighting products fund management Interim Measures " , to promote the rapid development of LED industry. November 4, 2011 , by the National Development and Reform Commission jointly issued by five ministries " gradual ban on the import and sale of ordinary incandescent lighting showroom ," made it clear that will phase out incandescent light, and plans to October 1, 2016 , general incandescent will completely withdraw from the market . NDRC also organized the drafting of the semiconductor lighting industry, " second five" plan , and the Ministry of Finance and green lighting policy reference , study and formulate measures to encourage the promotion of LED . Promulgation and implementation of this measure will be China's lighting industry has played a huge role in promoting.
Meanwhile , in the "five " emission reduction in the background, the Chinese government also introduced a series of lighting for public policies to encourage and accelerate China's environmental protection , energy saving and emission reduction pace , expanding domestic demand, LED products , LED lighting products to accelerate the promotion of application areas . Including the " city of ten thousand ", " thousand one hundred thousand ", " urban green lighting " and other related systems engineering , and promote awareness of LED lighting products , to create a good market space.
With LED role in energy conservation, development of related industrial restructuring , transformation of economic development and other aspects of further demonstrated that China is expected to introduce more effective measures to promote the development of LED industry , its market space policy space and has great potential to improve .
The status quo of China's LED lighting industry standardization After nearly a decade of development, China's LED industry basically formed a relatively complete industrial chain. At the same time , the development , the establishment of standards for LED lighting standards system has entered a rapid development stage . At present , the domestic standard LED semiconductor lighting project involved have basically covered all aspects of the epitaxial chips, packaged devices , products, applications, test equipment and other industrial chain.
The status quo of China's LED lighting industry distribution ( a ) in the "National Semiconductor Lighting Project" to promote , China has established a Shanghai , Xiamen, Dalian , Nanchang , Shenzhen, Yangzhou and Shijiazhuang seven National Semiconductor Lighting Project Industrialization Base . Domestic LED industry distribution as follows :
( 1 ) Pearl River : mainly concentrated in Shenzhen , Zhongshan, Foshan , Huizhou, Guangzhou, Jiangmen and Dongguan and other places. Pearl River Delta region is one of the semiconductor lighting industrial development of the most active and fastest growing region , package, and application of the largest in the country , recently , investment activity from the market, following the transfer of large foreign companies . The most obvious advantage is the market competitive advantage . LED lighting market in Guangdong accounted for 50% of the country . Among them, Guangzhou industrial base focused on research and development , testing, design and other high-end service platform and downstream packaging field , Shenzhen Semiconductor Lighting Industry has formed "Sapphire - epi - Grain - Packaging - application" complete industrial chain, Jiangmen focused on the downstream packaging , applications, and has been up and epitaxy midstream chip manufacturing extension .
( 2 ) The Yangtze River Delta : In Shanghai , Jiangsu and Zhejiang, Hangzhou , Ningbo, as the representative of the Yangtze River Delta , LED industrial supporting ability, outstanding high-end applications , personnel, funds are concentrated . Among them, Shanghai has been presented in the semiconductor chip manufacturing and packaging applications, a good development trend of the industry , and formed a relatively complete industrial chain and business groups ; Jiangsu semiconductor lighting industry , driven by the development of electronic information industry , is currently in the semiconductor lighting packaging and application has already begun to take shape ; Ningbo has a solid industrial base ( started earlier , as well as lighting manufacturing base ) and economic advantages.
Jianjun Du said heat pipe technology in 1963 Los Alamos National Laboratory invention heat pipe , mainly used in aerospace , military . Using the principle of heat conduction , in a closed envelope filled with working medium and the phase change medium using endothermic and exothermic heat exchange . Thermal capacity exceeds any known metal.Heat pipe technology PCCooler invention riveted fins , heat pipes using internal medium vapor , liquid phase change thermal conductivity, high density heat conduction from the LED light source to sink.Large area fins dissipate heat,quickly reduce the temperature of the light source , prolonging lamp life.
Air pollution, noise pollution, light pollution, are a threat to human health in recent years, several major killer. Two sessions, Premier Li Keqiang in the "Government Work Report" lists a number of specific measures in the field of energy and environmental transformation of the industry, I believe that this shows that the Chinese government's determination to control pollution in general, but also government attaches importance to balanced economic development model , restructuring determination. We can see that China will further reform to achieve more focused, more green economic growth, to pollution war.
