Shenzhen LED energy-saving lamp industry introduction
Shenzhen has included LED topics into the list of major industrial technology research topics, and Shenzhen has promoted the development of the LED energy-saving lamp industry in this way. "This is a sentence made by Wen Wenhui, Director of the High-tech Industrialization Division of Shenzhen Science and Technology Bureau, at the Conference on Interpretation of LED Energy-Saving Lamp Industry Support Policy. Just a week ago, the Shenzhen Municipal Government released three intensively in the form of a communique. A document on promoting the development of the LED and semiconductor lighting industry in Shenzhen.
Shenzhen should set an example for the LED energy-saving lamp industry
"I am very excited about Shenzhen's work to support the development of the LED industry. No matter from personal feelings or from an objective situation, Shenzhen's semiconductor lighting industry should play an exemplary role in the country." This is National Semiconductor Wu Ling, secretary general of the Lighting Engineering R&D and Industry Alliance, commented on Shenzhen's LED industry, "I often tell institutions and companies in other provinces that engage in LED energy-saving lamps, you are nothing, you have to go to Shenzhen to see."
The reporter also learned from relevant information obtained by the Shenzhen Science and Technology Bureau that the LED energy-saving lamp industry in Shenzhen began in the early 1990s. After more than ten years of development, Shenzhen's LED industry has developed rapidly. There are more than 700 companies engaged in the research, development, production and application of semiconductor lighting technology and products, accounting for nearly half of the country. In 2007, the industry scale was about 15 billion yuan, and the number of employees exceeded 120,000. At present, Shenzhen has become the world's largest production and supply base for solar LED lamps, a major global production and supply base for LED backlights, the largest domestic production and supply base for LED displays, and a major domestic production area for LED packaging and special industrial lighting.
The LED energy-saving lamp industry in Shenzhen is basically formed spontaneously by relying on the development of the electronic information industry, and a certain industrial agglomeration has been formed in various districts, showing the characteristics of relative concentration in Bao'an District and Nanshan District. From the perspective of enterprise agglomeration, Shenzhen LED energy-saving lamp enterprises are distributed in upstream substrate materials, epitaxial wafers, midstream chips, downstream packaging, application and supporting materials, processing and testing equipment and other links, and have formed a relatively complete domestic industrial chain. , and formed a certain industrial agglomeration in the middle and lower reaches of the industrial chain. According to incomplete statistics, among LED energy-saving lamp enterprises in Shenzhen, application product enterprises, packaging enterprises, and supporting enterprises each account for about 33%, and mid- and upstream enterprises such as epitaxial chips account for about 1%.
"Taking the domestic market as an example, Shenzhen occupies one-third of the entire market. From outdoor display screens to lighting applications, it ranks first in the country in terms of mid-end packaging and applications." Jinpeng introduced, " At the same time, Shenzhen also has considerable strength in front-end chip design, and Shenzhen is currently building the world's largest front-end chip production base."
According to the data, Shenzhen LED energy-saving lamp enterprises have taken the lead in making breakthroughs in the application market of backlight, display screen, solar LED application, special work lighting, etc., enabling LED enterprises in the above-mentioned fields to develop rapidly. Under the promotion of the municipal government's policy of encouraging technological innovation, the technological innovation capability of Shenzhen's LED industry has been gradually enhanced, and a number of independent innovation enterprises have emerged. As of June 2008, Shenzhen LED enterprises have applied for 1,121 patents, ranking first in the country. head. From the perspective of product structure, the product distribution of Shenzhen LED industry is very extensive, almost covering the upper, middle and lower reaches of the current LED industry. In 2007, epitaxy and chips accounted for less than 1% of total sales, packaging accounted for about 30% of total sales, applications accounted for about 60% of total sales, and matching accounted for about 9% of total sales.
"However, most of the core patents of LED energy-saving lamps are in the hands of foreign companies, so our LED product exports often encounter technical and patent barriers of one kind or another." Jinpeng said with some regret, "For example, the use of phosphors, Phosphors and blue light are applied for such patents. The patent coverage of foreign companies is relatively wide.”
