Shenzhen LED industry gets the policy support
"This is that Shenzhen includes LED subject in the great industry's technological brainstorm subject list for the first time for over ten years, also Shenzhen's the first time promote the development of LED industry by this way. " This it is the intersection of Shenzhen and the intersection of department and the intersection of letter and the intersection of office and the intersection of new and high technology and the intersection of industrialization and first division chief Wen WenHui that support the policy to understand a word at the conference in LED industry. And just one week ago, the government of Shenzhen released the file about promoting LED and semi-conductive lighting industry development of Shenzhen of the triplet intensively in the form of communique.
"We feel and inspire very much, very glad too. The city leader paid close attention to industry of ours so at last " ,Several semiconductor light and the intersection of LED and director of enterprise express the same heartfelt wishes simultaneously, " think now that there is energy very much " .
Shenzhen should play example craning one's neck to look into the distance and exemplary role
"The work that Shenzhen supports the development of LED industry now, let me feel very excited, no matter from a person's emotion, from the objective situation, the semi-conductive lighting industry of Shenzhen should play the example to crane one's neck to look into the distance on demonstrative function in China. " This is researched and developed by a national semi-conductive illuminating engineering and appraisal on Shenzhen LED industry of general secretary of industry alliance Wu Ling, "I often do the other provinces organization and enterprise of LED say, you are nothing, you must go to Shenzhen to have a look. "
The reporter knew from the related data which the letter office of the department of Shenzhen obtains too, Shenzhen LED industry started at the beginning of the 1990s of last century. After several decades of development, Shenzhen LED industry is fast growing, are engaged in studying, developing, producing in semi-conductive lighting engineering and products and applied enterprises have been already up to more than 700, near the independent section of country China. 2007
The annual scale of industry is about 15 billion yuan, staff's number exceeds 120,000. At present, Shenzhen has already become production and supply base of global maximum of solar energy LED lamps and lanterns, global master production and production and supply base of the supply base, LED display screen Chinese maximum of LED backlight source, LED capsulation and special industry lighting China mainly produce the area.
Basically the development which relies on the electronics and information industries is spontaneous and formative for Shenzhen LED industry, form certain industry to gather in every district, appear in Baoan district and relatively concentrated characteristic of Nanshan District. And view from the point of gathering in enterprises, Shenzhen LED enterprises are distributed in upstream substrate material, epitaxial wafer, the chip of state of being middling, get each link such as capsulating, employing and related material, processing and checkout equipment in the low reaches, have already formed the Chinese relatively intact industry chain, and formed certain industries to gather in the industry chain midstream and downstream. According to the incomplete statistics, in Shenzhen LED enterprises, employ products enterprises, capsulate enterprises, related enterprises and account for 33% respectively, upper and middle reaches enterprises such as the epitaxy chip,etc. account for 1%.
"Take Chinese market as examples, Shenzhen has occupied the share of the 1/3 of whole market, from outdoor display screen to application of lamps and lanterns, in the end of China is capsulated and employed, it is first to rank in China. " The gold roc introduces, " at the same time, Shenzhen has considerable strength on the chip design of forward end too, Shenzhen is making the largest forward end chip production base in the world at present. "
Materials reveal enterprise, LED of Shenzhen, LED employ and special work light etc. to employ the market to take the lead in making the break-through in backlight source, display screen, solar energy, make LED enterprises of the above-mentioned several fields get faster development. Under the circumstances that the municipal government encourages the push of the scientific and technical innovation policy, the technological innovation ability of Shenzhen LED industry is strengthened progressively, having already appeared in the enterprises of batch autonomous innovation, by June of 2008, 1121 applications for patent altogether in Shenzhen LED enterprises, the location occupies the first place in China. By the look of product structure, it is very extensive that the products of Shenzhen LED industry are distributed, the products big class of nearly containing on, in LED industry at present, low reaches. In 2007, epitaxy and chip account for gross sales amount less than 1%, capsulate and account for 30% of gross sales amount, should use and account for 60% of gross sales amount, form a complete set and account for 9% of gross sales amount.
"But the key patent of LED, mostly grasp in the hands of the foreign enterprise, so our LED products export will often encounter all kinds of technology and patent barrier. " The gold roc is a bit sorry to represent, " for example use phosphor powder, phosphor powder to add the blue light, others apply for such a patent. The patent coverage rate of the foreign enterprise is wider. "
LED popularizes and still needs to lower costs
Regard as the intersection of Shenzhen and the intersection of electronic messaging and exquisite senior statesman, the intersection of industry and hall Wang, president of federation, LED of Shenzhen, of trade, show while speaking of the application of LED just, though China is the big producing country, does not employ big countries, especially in lighting at ordinary times, what everybody basically still used is traditional illuminations.
"In China, LED mostly uses on display screen and car electron outdoors, for example that kind of large-scale display screen, again for example car tail lamp, 50% of the ones that used in the tail lamp technically of new car is LED at present, perhaps will expand to 80% later. LED illumination is abroad at present, especially what American-European countries popularized is the most extensive, but it is not very abundant to popularize in China. " The gold roc thinks, it has not been popularized in China effectively that LED in the daily common illuminations, closely bound up instead of present production cost and selling price, prices of LED are a lot higher than the price of traditional illuminations.
"Take a room lighting demand of 10 square meters as examples, the light quantity requires 600 lumens per watts, need one watt of bulbs with incandescent lamp bulb, need, spend first 5 watts only with LED, want but price of LED each by 20 yuans,it is then 5 watts must 100 yuans,you how much incandescent lamp bulbs ordinary need? " Jin Peng says.
Meanwhile, Jin Peng represents, it is causing LED key factor with high price that the material cost in the production cost is high.
" a LED lamp of now, the cost of the chip accounts for more than 50%, " Peng Jin say " a lot of LED to make base with sapphire in chip, even some spend expensive carborundum. "
Though because the price factor causes LED it is unable to be popularized effectively in residents light at ordinary times, but the gold roc thinks LED is still very advantageous in urban public transport and road lighting.
"First of all, LED is energy-conserving, the usual street lamp lighting power consumption is so large, can save many energies with LED; Secondly, the serviceability of LED is very good, install one after going up, needn't go to change for a long time, like this too
