As one of the emerging strategic industries, the LED its excellent luminous efficiency and lifetime of a new generation of light "choice" in recent years, substantial investment flocked to involve enterprise scale exponentially expand, but the LED industry The development is not satisfactory.
"Despite the progress of China's LED industry is obvious, but the core technology is not yet achieved a fundamental breakthrough in the industrial structure needs to be further adjust and optimize the standards and testing system is urgent need to establish and perfect the key issues are still plagued by industrial development." Industry and the Ministry of Information Electronic Information Division Ding Wenwu think. Vice chairman Chen Yansheng of China Association of Lighting in an interview with the China Electronics News "reporter also said that in recent years, from central to local levels, the development of LED's alive. The "hot" pros and cons, so many people are concerned about the LED lighting industry is not a bad thing, but a good thing. However, the LED industry practitioners should stay calm, rational consideration, to reduce blindness and to increase the scientific and reasonable.
Through years of development, to the end of the LED industry in China has achieved great progress. At present, the LED industry in China has entered the fast lane, will inevitably encounter all kinds of difficulties and challenges: the high value-added sectors of the global industry is still a small number of foreign corporate monopolies, the domestic enterprises, the core patent has too little; substrate epitaxial chip investment overheating lead to overcapacity, the manufacturer of sapphire substrates (including build) has reached 41, a total of 44.7 billion yuan investment, production capacity of approximately 330 million / year, far greater than the actual demand; LED epitaxial silicon project is already (including 85 under construction), the total investment amounted to 183.5 billion yuan, 2012 China's LED chip production capacity is expected to reach 10 times in 2010; LED package, gross profit margin also dropped significantly; reliable stability of LED lighting applications nature remains to be further improved competitive strength of enterprises need to differentiate; industry standard is to be further improved.
Industry, sustainable development, the enterprises bigger and stronger has been the common expectation of the Chinese LED industry insiders. Faced with various problems encountered by the industry, the industry also actively brainstorming Industrial Alliance ready to come out.
Ding Wenwu, LED is a high-tech cross-cutting areas, and extends to the lighting and other fields from the field of electronic information, an urgent need for coordination of industry chain, interactive development. In this case, the need for unified planning and management of the entire industry from the national level, the industry is eager to set up a unified national industry organization. Industrial and information technology, consumer goods industry, Deputy Director Gao Yan Min also said that the establishment of China's semiconductor lighting / LED industry and application of Union, is to establish production, learning and research, with the integration of the linkage mechanism, a collection of China's semiconductor lighting industry chain , the middle and lower reaches of the manufacturers, industry associations, research institutes, the power of rational planning of industrial layout and development goals, the effective integration and rational allocation of industrial resources, the joint to overcome the constraints of China's semiconductor lighting industrial development core, common technical problems to actively guide the Union according to their own actual situation, the development of differentiated semiconductor lighting technology and products, to prevent redundant construction and vicious competition.
Optoelectronic devices branch chairman of the China Optics and Optoelectronics Manufactures Association Yangke Wu said that to change the current industry "disorder", an urgent need for government departments to further strengthen the right to guide the establishment of a coordinating body to promote the development of LED industry, set up LED business and government departments communication between the platform to integrate the industrial and social resources, including to the industrial transformation of scientific research to promote the independent innovation, promote the construction of IPR service platform and product testing platform, promote the development of standards and Publicizing of LED products, organizations LED related training and consulting services.
The Yang Kewu believe that the "12th Five-Year" period China's LED industry will have many unknown variables and suspense, Industrial Alliance's role and influence is bound to give full play. In the industry alliance to promote market competition, survival of the fittest, industrial development will shift from disorder to order.
Indoor commercial lighting era
There are many LED applications such as backlight, display and lighting. 2011, with color TV and other terminal markets is lower than expected, the backlight market remained weak. The display area in the past to "leapfrog" development, the market is becoming saturated. At present, the lighting market to become the new darling of the LED applications.
"LED lighting is the most attractive areas of the eye, the industry, capital and government have placed unlimited expectations. The driving effect of the successful application of special lighting and major demonstration projects, combined with national policy guidance in terms of energy saving and environmental protection, making the LED lighting times ready to come and go all the local governments at all levels, LED lighting hope to fight the emerging industrial growth point, the fear of missed development opportunity. "China Optics and Optoelectronics Manufactures Association, vice chairman, LED display applications branch chairman off the plot Jane told reporters .
However, LED lighting covers a very wide and can be divided into civil lighting and commercial lighting, can be divided into indoor lighting and outdoor lighting. Industry experts believe that China should be based on existing conditions and the level of industrial development, efforts to give priority to the development of local markets, obtain the "Xinghuoliaoyuan effect. Large-scale civilian lighting is the common aspiration of people in the industry, the price of LED lights continued to fall, but compared with the energy-saving lamps in the price is still not competitive, the industry is still relatively far away from the goal of large-scale civilian lighting. Therefore, commercial lighting, LED lighting applications.
So, for both indoor and outdoor lighting environments, Which is better what times? "In the field of LED lighting applications, LED outdoor lighting such as LED street lights to promote them more difficult, its power, the outdoor environment is relatively poor, is not suitable for large-scale promotion of small power of indoor products, the environment does not like outdoor so bad, the temperature will not change much, LED lighting early applications should focus on the interior lighting. "Chen Yansheng said.
Professor Zhang Wansheng of the 13th Institute of China Electronics Technology Group Corporation, told reporters May 1, 2010, LED street lighting standards require the average life expectancy of the lamp should not be less than 20,000 hours, efficient sodium lamps of life comparable with this, and has a higher luminous efficiency (135lm / w), the lower the color temperature and price, and better interchangeability. In addition, LED lights The biggest problem is the light source module and the power is still difficult to conduct on-site replacement and maintenance. LED street lamp is still in the development and improvement of the future, although beautiful, but not as a mature product to promote, to the formation of a viable national and industry standards will take some time.
It is understood that the LED indoor lighting applications there are many, the most important thing is the bulb lights, reflective lights, downlights, fluorescent tube lights, plate lights. Japanese market to the bulb-type light-based, while U.S. and European markets on reflective light. In addition, LED light sense very strong, so the focus of the downlight is also the current application. Chen Yansheng, these three types of LED lights are to be encouraged, and are suitable for the domestic market and the application environment. Fluorescent tubes, LED lights, not too encouraging, its security problems. To apply plate lights, the lamps should be replaced, the cost will be higher, but flat-panel lights may be one of the future direction of the application . "
