There from the end of the problem
South Korea LED industry will become the strongest competito
Forum, Industrial Technology Research Institute of Electronics and Optoelectronics Zhanyi Ren said the recent 10 years, the development of semiconductor lighting very quickly, but also the global situation has undergone great changes in the overall industry. Europe and the United States and Japan, output declined in direct proportion, in which the Japanese LED industry, the cost is its Achilles heel. Because the sound development of LED industry, not only have good technology, but also has strong production capacity and huge market, if production costs are too high, also limit the industry's growth. The Asian countries are gradually increasing the proportion of output, especially in South Korea, the proportion increased rapidly in recent years. Because Korea is not only considerable technical potential, but also has a strong system of production capacity, with Samsung and other systems strong strong LED business, its value will further increase the proportion of the future will be a strong competitor.
As for Taiwan, the proportion of output value maintained at about 25% -30%, but the lack of a strong corporate brand in Taiwan system vendors, and more Taiwanese companies to OEM the main orders of business development at any time. China has more than 3,000 LED manufacturer, has a certain scale. Therefore, strengthening cross-strait cooperation, strategic alliances, will be a breakthrough in China's LED industry.
Alternative products,T5 light to high efficiency , LED difficult to be replace
LED lighting alternative to the traditional difficulty of six tables
At present, LED lighting into the market, mainly in the alternative, instead of asking, and LED lighting replaces the traditional ease of Epistar special assistant to general manager Wang Xiwei Corporation said, LED lighting products with competitors about replacement level of difficulty. Point of view from the top, LED is the most likely to beat the incandescent lamp, followed by the bulb, MR16, GU10 lamp, PAR lamps, LED down light current applications are more and more mature, street lamps ranged Downlight, T8 of the , the most difficult to replace the T5, T8, mainly because of T5, T8 high luminous efficiency, LED current level of technology is hard to see replaced. And a large number of applications mainly in the light with T5, not lighting. In addition, Wang point out that the replacement market is a great product compatibility issues, and with the decline in chip prices, lighting for 95% of compatibility, LED lighting is better applications. Of course, the market itself is just a transitional alternative, LED commercial lighting market will gradually mature, such as hotel lighting market will be relatively large space. The mining lighting, power more than 100W or more lighting, there is price.
LED products to the high pressure will dominate the future of LED general lighting market
The forum, Epistar, Di source of optical light-emitting diodes are pushing high-pressure (HV LED) chips. The same output power, high voltage LED current is much lower than needed to drive low-voltage LED, heat aluminum housing costs can be greatly reduced. DC LED products currently there are some drawbacks in the application needs to be used in conjunction with the transformers and other components, and the life span of only 20,000 hours, while the actual LED chip life is up to 5-10 million hours. By contrast, HV LED is no additional transformer, just a short drive circuit, the device reliability, the structure will also be more compact, the application cost is significantly reduced.
Experts have pointed out, such as high pressure to develop LED general illumination LED lighting products, the overall power consumption can be greatly reduced, thus significantly reducing the design of the cooling housing requirements, such as we can use thinner and lighter aluminum housing can meet the heat dissipation LED lamps demand due to the cost of heat is the aluminum casing LED lighting one of the major cost components, aluminum enclosure means to reduce the overall cost of LED lighting to reduce costs. Thus, high-voltage LED lighting, LED lamps can bring the effective cost and weight reduction, but even more significant is the sharp decrease of the cooling system requirements, thus effectively clearing the LED lighting market into the largest indoor lighting technical obstacles. Therefore, high pressure will dominate the future of LED lighting, LED general lighting market.
Enterprise development will work together to promote the development of LED products to modular
The forum, many experts have talked about LED lighting products, and promote, they all agreed that the one word - modular. Lamps and Lighting Engineering, Fudan University, Lighting Research Institute Professor Liu Muqing Shanghai Yangtze River Tunnel with the operations of LED lighting systems that: Although the Shanghai Yangtze River Tunnel lighting power, lighting, wiring and other less than 3% of total failure, but the lighting could not spot open, so All repairs must be returned to the factory, maintenance caused a lot of trouble, it is Tunnel LED lighting one of the major problems facing. Thus, Professor Liu said, the overall increase in LED tunnel light tunnel lights the difficulty of maintenance, the proposed modular LED tunnel light of the technology.
The Pei Xin Energy Technology Co., Ltd. (Foxconn Technology Group) Ji-Zhong Hu said in a report, now flourishing domestic and foreign manufacturers, have launched the "kinds" of LED lighting products, but are mostly not interchangeable, not compatible with each performance. The Lighting Group Co., Ltd. Zhejiang Sunshine Yong, general manager of the official also told the actual market itself in the confusion, LED technology updates too, just listing product is easy to become obsolete, so difficult to deal with dealers. Together with spare parts and new product performance can guarantee compatibility, but also become a problem.
Therefore, Ji-Zhong Hu pointed out that "interchangeability" "compatibility" and "universal" is the lighting product development and market acceptance of a crucial element. This involves the modular design. Module is a standard, independent, and is replaceable units, modular design that is in the process of product design and development of functional components related to the operation based on the product architecture into a single module, the module through the analysis of the correlation between the composition and working procedures of the design and determine the best combination of the desired interface module configuration.
Believe that the future of domestic manufacturers will work together to continuously improve product design and development capabilities, to promote modular LED products, promote large-scale LED in general lighting application.
The direction of LED technology will become the research and development of intelligent technologies that can be grown
In this new light source of new energy lighting forum, many experts and professors have pointed out that LED, LED light source is a low-voltage microelectronics, the integration of computer technology, network communication technology, image processing, embedded control technology and its applications The lighting, the firm is more to play more of its luminescence properties, for its control, wireless programming, flexible and so did the maximum utilization.
Industrial Technology Research Institute of Electronics and Optoelectronics Zhanyi Ren says that some of the characteristics of future intelligent LED will be the focus of major research institutions, and respect to the growth of LED technology. Intelligence is mainly reflected in: on the one hand, making lighting effects, how to better control the color temperature; the other hand, can be developed to adapt to different climatic conditions of the LED light source, such as for agriculture lighting, adjust the growing season, changes Animals and other production periods of time. LED future application areas will be gradually extended to the surgical lights, dental lights, endoscope. In addition, LED lighting research and development will increasingly focus on human perception, the human eye comfort and so on.
Coincidentally, Sony Source Co., Ltd. Sichuan, Zhang also pointed out that: "the original function of lighting is LED, LED meaning very rich, you can extend upward, such as LED lighting to do, enabling wireless Internet access capabilities, the future does not need wires, a LED Where there is electricity. Therefore, LED may be in the next 5-8 years subvert the present mode of communication. research institutions and enterprises to do is to develop LED emerging markets, digging LED rich connotation. "
