South Korea will become China's strongest rival LED industry

In 12th Five-Year as the first year of planning, 2011 Chinese LED lighting industry ushered in new opportunities, is also facing challenges. LED lighting industry in China will be how to meet the opportunities and challenges in the next few years, the focus of LED research and development of the market where? May 11th -13, the fifth session of the Shanghai international new light & New Energy Lighting Forum held. People of Chinese and foreign politics and business and industry together to discuss plans for the development of LED industry.

South Korea LED industry challenges will become the strongest competitors

Forum, Industrial Technology Research Institute of electronics and optoelectronics, said Zhan Yiren, director of the last 10 years, the rapid development of semiconductor lighting, but also to make a huge change in the global industry as a whole. Europe and the United States and Japan, the proportion of output is declining, of which, the Japanese LED industry, the cost of its fatal injury. Because of the healthy development of the LED industry, not only to have a good technology, but also a strong production capacity and a huge market, if the production costs are too high, it will limit the growth of the industry. The proportion of output value of Asian countries is gradually rising, especially in South Korea, in recent years, the proportion of rapid growth. Because South Korea not only have considerable technological potential, also has a strong production capacity, with Samsung LED system and strong enterprise strength, its output value proportion will further increase, the future will be a strong competitor.

As for Taiwan, the proportion of output value is probably maintained at 25% - 30%, but the lack of a strong brand of Taiwan enterprises, and Taiwan enterprises to OEM based orders will affect the development of enterprises at any time. China has more than 3 thousand LED manufacturers, with a certain scale effect. Therefore, strengthening cross-strait cooperation and strategic alliance will become a breakthrough in the development of China's LED industry.

Alternative products T5 light effect is too high, the most difficult to replace LED

LED to replace the six types of traditional lamps of the degree of difficulty table

At present, to enter the field of LED lighting is mainly in the replacement market, and asked about the difficulty of LED to replace the traditional lamp, Jingyuan Au Optronics Co general manager assistant Wang Xiwei pointed out, LED lighting products replace the degree of difficulty associated with competitors. From the top view, LED is most likely to beat the incandescent lamp, followed by bulb, MR16 lamp, PAR lamp, GU10 lamp, current LED applications are becoming more and more mature, is situated between the street lamp and T8, the most difficult is to replace T5, T8, T5, T8 is mainly because the light is too the high level of technology, the LED is also very difficult to replace. And a large number of T5 applications mainly in the band, not lighting. In addition, Wang pointed out that the replacement market is a big problem is the compatibility of the product, but with the decline in the price of the chip, the lamp applies to compatibility of 95%, lighting will be a better application of LED. Of course, the replacement of the market itself is only a transition, LED commercial lighting market will gradually mature, such as hotel lighting market will have a relatively large space. The industrial lighting, power over 100W lamps, there is a price problem.

Products to high voltage LED will dominate the future of LED general lighting market

This forum, EPISTAR, di are pushing high voltage source photoelectric light-emitting diode (HV LED) chip. Under the same output power, the drive current required by high voltage LED is much lower than that of low voltage LED. At present, there are some drawbacks in the application of DC LED products, the need to use together with transformers and other components, and the life of only about 20 thousand hours, while the actual life of the LED chip is up to 5-10 hours. In contrast, HV LED does not require additional transformers, just a short drive circuit, the device is more reliable, the structure will be more compact, the application cost is greatly reduced.

Experts have pointed out, such as the use of high pressure LED to develop LED general lighting products, the overall power consumption can be greatly reduced, thereby significantly reducing the design requirement of the radiating shell, such as we can use thinner aluminum shell lighter can meet the cooling demand of LED lamps, the radiating aluminum shell cost is the main cost of LED lighting one of the components, effectively reduce the aluminum housing costs also means to reduce the overall cost of LED lighting. Thus, effectively reduce the pressure of LED can bring the cost of LED lighting and weight, but the more important is to dramatically reduce the requirements of the design of the cooling system, which effectively cleared the biggest obstacle technology LED lighting into the indoor lighting market. As a result, high voltage LED will dominate the future of the LED general lighting market.

Enterprise development will work together to promote the development of modular LED products

The forum, many experts talk about LED lighting products to promote the application, are invariably referred to a word - modular. Department of electrical engineering Fudan University Lighting Research Institute Professor Liu Muqing light combined with the operation of Shanghai Yangtze River Tunnel LED lighting system pointed out: Although the Shanghai Yangtze River tunnel lighting power supply, light source, etc. the total wiring fault is lower than 3%, but the lamp can site opened, so all the maintenance must be returned to the factory, caused a lot of trouble to repair, this is one of the main problems of LED tunnel lighting faces. Therefore, Professor Liu said that the overall LED tunnel lights increased the difficulty of the maintenance of the tunnel lights, it is recommended to study modular LED tunnel lamp technology.

The new energy Polytron Technologies Inc (Hon Hai Technology Group) Hu Jizhong in the report pointed out that now the domestic and foreign manufacturers to blossom, have launched a variety of LED lighting products, but
