Domestic LED lighting industry technology trends
China’s LED lighting technical gap is the core equipment and raw materials still need to rely on imports, domestic LED enterprises led distributors demand for equipment and materials, the proportion of imports from the upstream to the downstream industry presents a descending trend.
At present, China’s self-developed supply LED chip and wafer production is still relatively limited, product-based, low R & D technology is relatively weak, and had to rely on imports about 85% of the high-power chip. Existing domestic LED chip technology led distributors is tracking the development of foreign technology, very few original technology, lack of sustainability of the basic level of research and development, has not yet formed the independent intellectual property rights of the patent system. In this regard, the government has introduced various support policies in support of efforts to increase the localization of key equipment, materials, and by encouraging cooperation within the industry and research ways to gradually accelerate and promote technology research and development of the domestic LED lighting industry and Application of the process of realization.
Aspects of packaging and application of LED lighting industry, the domestic LED lighting to package high-end products, and light source products will gradually upgrade the direction of its efforts to improve the existing domestic Portable LED Explosion Proof Flood Lights packaging and lighting applications is still mainly in the status of the application level of the low-end market.
The future, with the rapid development of LED technology, LED lighting costs will gradually decline. According to the forecast of the U.S. LED lighting technology and applications, in 2012 and 2020, LED lighting cost of ownership (including the LED from the purchase, run to the end of life in the total cost of the entire cycle) will be as low as 1/3 of the 2007 level and 1/5 level. LED lighting costs reduce the stability of the technology will effectively drive the LED lighting market is booming, accelerate the LED lighting alternative to traditional lighting speed, gradually expanding penetration in the field of lighting applications.
Second, LED lighting industry development status
From a global point of view, the LED lighting industry has formed led to the United States, Europe, Asia, the three major regional distribution of industries and the competitive landscape. Currently, the United States, Japan, Europe has advanced product development of the LED industry, technology and innovation advantages, mainly engaged in the production of high value-added LED products led distributors. The same time, all the major manufacturers in the United States, Japan, Europe is positive expansion, accelerate seize global market.
In recent years, China’s mainland and Taiwan LED industry, the rapid rise of development now occupy the first in the world for the packaging production, the output value of the second highest in the world, and Taiwan on the chip R & D and manufacturing advantages are gradually revealed.
Promotion of National Semiconductor Lighting Project, China has initially formed including LED chip, LED packaging and LED application, including a more complete LED industrial chain, and has 4 large area, 7 large base of industrial pattern, that has long triangle, the Pearl River Delta, Fujian Triangle and the northern Bohai Sea area as the development of LED industry gathering place, as well as Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang seven countries semiconductor lighting industrial bases.
LED industry chain structure, LED upstream industries are technology and capital-intensive industries, financial and technical demanding, high barriers to entry, the existing domestic production and R & D technology still a wide gap compared with developed countries. Downstream industries are technical and labor-intensive industries, the relatively high technical and financial requirements, the rapid development of domestic LED industry links, the gap between domestic and international markets has been significantly reduced.
