Star of hope - development and Prospect of China's LED industry

Before the core strengths of the two types of enterprises are relatively concentrated, the investment value will be the first show.

Third types of enterprises are excellent downstream packaging enterprises, such as Xiamen Hualian, Foshan star optoelectronics, etc.. A major feature of the development of the domestic large-scale integrated circuit packaging field is local enterprise development than in the field of design and manufacturing, packaging is estimated in the field of LED enterprises will also have good development opportunities for development, even faster than the upstream and midstream epitaxial chip companies, because the packaging enterprises can purchase foreign chip to meet domestic market demand, and domestic enterprises will follow the progress of chip technology roadmap. LED, white LED light effect in part through encapsulation, other color light must pass a package into devices can be used in the terminal market, the level of packaging technology will directly determine the overall development of the LED market! At present, LED is mainly concentrated in the downstream packaging industry, but the low level of packaging most of enterprises, resulting in fierce competition, with the terminal market to upgrade, excellent downstream packaging enterprise brand is becoming more stable, more advanced technology, is bound to reflect the investment value of talent shows itself.

Fourth types of enterprises will rise in the LED field of general lighting in the future, such as lighting system design, professional training brand LED general white light lamp and lamp manufacturers, as the largest market of LED application, some high investment value of the enterprise behoove, but rather a long time.

Fifth types of enterprises in the field of electronic materials outside the LED industry chain, such as silicon, silicon resin, package with a lead frame and a heat radiation module; chip field and LED driver, currently in these areas is still relatively weak, to go through a period of growth, the growth of the driving chip is estimated to be faster than other peripheral areas. The drive chip industry is quite successful in LCD, there was little benefit, mainly because the downstream market (manufacturers) lack of integrated circuit design and manufacturing base is relatively weak, now the semiconductor lighting extremely broad market to drive downstream domestic chip industry development opportunities, I believe there will be a number of enterprise talent shows itself.

In terms of listed companies, Silan optimistic about the prospects, the bright blue green extension, chip industry has a "core value" technology breakthrough in power LED driver chip has launched products, in the market have a certain reputation in the operation of the chip industry technical extension, further mature and reach a certain size after the company is expected to enter the downstream packaging market, open up the industry chain.

2006 sales of LED products accounted for only 5% of the company's total sales revenue, while accounting for the company's sales revenue of less than 80% of the integrated circuit business is not stable, covering up its LED product highlights. 1.5~2 LED chip is expected to billion in 2007 sales revenue, sales revenue accounted for up to more than 10%, in 2008 the company from the current 100KK chip production capacity will be increased to 300kk per month, with the LED product in the company continuously improve the proportion of sales revenue, the company expects 2009 will appear to change the product structure to promote the "value" of the inflection point, LED the value of the investment will be reflected.

LIAN is a listed company LED related products accounted for the largest proportion of sales revenue (about 30%) and the company LED products as the focus of future development of the enterprise, the company implements the strategy to drive in the middle and lower reaches of the upstream, downstream in the proportion of sales package is biggest, followed by the middle reaches of the chip, is the upstream extension again. In the upstream extension, especially bright blue green extension, the company has not achieved a breakthrough; the company currently is the main chip company LPE machine (four) production of red green Pu bright wafer, 2007 output will reach 10 billion; in the downstream packaging industry, the overall level of Xiamen Hualian packaging technology leading domestic holding company, see from the industry, the low-end packaging market, domestic competition, high-end packaging technology to further mature, high-end market will further open up the package, so the Xiamen Hualian performance is not particularly prominent, but also experienced a period of growth.

LIAN Nanchang branch has engaged in packaging business, if LIAN can be led in the downstream integration of resources, focus, with the current overall level, development prospects become clear, but the market reflects the LIAN name of Hualian Holdings (7.93, -0.17, -2.10%), the actual control power co.. If LIAN in the upstream and downstream integration difficult, bright blue and green extension of the core technology is not a breakthrough, the overall resources scattered, its long-term development orientation is not very clear, decisive role of LED products on the long-term value of the company's no clear timetable. LIAN opto other business are high-quality assets, which makes it have time to integrate their LED related resources, construct the core values of LED; and the sales gross margin of 23%, while the sales net interest rate is only 3%, so if the integration, yielding the effect will be more obvious. As the only listed company as the main industry in the future LED, LIAN photoelectric future development is worth continuing concern.

Shoot power of 150mW, up to 189mW. Nanchang University recently carried out a study on growth of GaN epitaxial material on silicon substrate, blue chip has developed emission power up to 7mW ~ 8mW, the best is 9mW ~ 10mW, the yield of the chip is 80%, power LED chip in 350mA transmitting power is 100mW ~ 150mW, the best is 150mW. Electricity test in 500mA, 1000 hours, less than 5% of the light blue. The results made breakthrough progress, through the "863" project acceptance, and access to a number of independent property rights of international invention patents. The patent broke the present Japan Nichia monopoly sapphire and the U.S. monopoly Cree silicon carbide substrate of semiconductor lighting technology
