Nanfang Daily: LED industry ushered in the policy of spring

This is the first time in Shenzhen over the past decade, the LED will be included in the list of major industrial technology research projects, but also the first time in Shenzhen to promote the development of LED industry. This is the Shenzhen Municipal Bureau of science and technology, a high-tech industry in the LED director Wen Wenhui industry support policy interpretation of the general assembly.

And just a week ago, the Shenzhen municipal government in the form of bulletin, densely released three documents on promoting the development of the city of LED and semiconductor lighting industry in Shenzhen.

"We are very excited and happy. City leaders are so attached great importance to our industry, a number of semiconductor lighting and LED companies responsible for the same expression of the same aspirations, and now feel very motivated".

The Shenzhen should play an exemplary and leading role model

The development of LED industry in Shenzhen to support the work now, so I feel very excited, in terms of personal feelings, or from the objective situation, the Shenzhen semiconductor lighting industry in the country should play an exemplary role of leading. This is the national semiconductor lighting engineering research and development and Industry Alliance Secretary General Wu Ling on the evaluation of the LED industry in Shenzhen, I often engage with other provinces LED institutions and enterprises to say, this is not what you, you have to go to Shenzhen to see. "

Reporters also learned from the Shenzhen branch of the relevant information bureau, Shenzhen LED industry began in the early 90s of last century. After ten years of development, the rapid development of the LED industry in Shenzhen, engaged in semiconductor lighting technology and product research, development, production and application of enterprises has reached more than and 700, accounting for nearly half of the country. 2007 industrial scale of about $15 billion, the number of employees more than 120 thousand people. At present, Shenzhen has become the world's largest solar LED lamp production and supply base, LED backlight major global production and supply base, LED display the largest production and supply base, LED packaging and special industrial lighting domestic main production area.

Shenzhen LED industry is based on the development of electronic information industry, formed in a certain area of industrial clustering, showing the characteristics of the relative concentration of Baoan District and Nanshan District. From the enterprise cluster, Shenzhen LED enterprises located in the upstream of the substrate materials, epitaxial wafers, chips in the middle, to all aspects of the downstream packaging and application and supporting materials, processing and testing equipment, the domestic has formed a relatively complete industrial chain, and industry chain downstream formed certain industrial agglomeration. According to incomplete statistics, Shenzhen LED enterprises, the application of enterprise products, packaging enterprises, supporting enterprises accounted for about 33% of the total, epitaxial chips and other upstream enterprises accounted for about 1%.

In the domestic market, for example, Shenzhen accounted for 1/3 of the total market share, from the outdoor display to lighting applications, in the end packaging and application in the country are ranked first. Jinpeng introduced, at the same time, Shenzhen has a considerable strength in the design of the front-end chip, Shenzhen is currently creating the world's largest front-end chip production base. "

Statistics show that Shenzhen LED enterprises in the backlight, display, solar LED applications, such as the application of special lighting market first to make a breakthrough, so that several areas of LED companies have been rapid development. In the municipal government to encourage technological innovation policy, Shenzhen LED industry technology innovation ability gradually increased, there have been a number of independent innovation of enterprises, by the end of June 2008, Shenzhen LED company a total of 1121 patent applications, ranked first in the country. From the product structure, the distribution of products in Shenzhen LED industry is very broad, covering almost the current LED industry, the middle and lower reaches of the major categories of products. In 2007, the total number of chips and chips accounted for less than 1% of the total packaging accounted for about 30% of total sales, accounting for about 60% of the total sales, supporting about sales of about $9%.

"But LED's core patents, mostly in the hands of foreign companies, so our exports of LED products often encounter such or such technical and patent barriers. "Jinpeng some regrets," such as the use of fluorescent powder, fluorescent powder and blue, so people have to apply for a patent. Foreign companies have a wide range of patent coverage. "

The LED extension still need to reduce costs

As the city of Shenzhen electronic information industry hall veteran, Shenzhen LED Industry Association President Wang Dianfu said in the application to talk about LED, although China is producing country, but not the application of power, especially in the daily lighting, traditional lighting tools are all basically with the.

"In China, LED is more used in outdoor display and automotive electronics, such as the large screen, for instance car taillights, the new car in the 50% tail lights are used in LED technology, the future may be extended to 80%. LED lighting is currently abroad, especially in Europe and the United States to promote the most widely, and in the domestic promotion is not very full. "Jinpeng believes that LED in the daily general lighting in the domestic popularity has not been effective, its current production cost and sales price is closely related to the price of LED than traditional lighting tool prices are much higher.

"In a 10 square meter room lighting demand as an example, light 600 LM / W, if you need a 40 Watt light bulb of incandescent bulbs, but LED only need to use a 5 Watt LED, but a price will be 20 dollars, then 5 watts to 100 blocks. You are a common incandescent lamps only need how many money?" said Jin Peng.

At the same time, Jinpeng said that the high cost of materials in production costs is the main factor leading to high prices of LED.

"Now a LED lamp, the cost of the chip is accounted for more than 50%," Jin Peng said, "a lot of LED chips are made of sapphire substrate, and even some of the more expensive silicon carbide. "Although the price factor led to the LED can not be residents in the daily lighting
