LEDs (light-emitting diodes) can be said to be ubiquitous in our lives. Whether it is traffic lights on the road or flashing lights of cameras, more and more sources of light have been converted to LEDs. Consumer electronics, such as mobile phones and iPods, have long used LEDs as backlights. In particular, the magical scrolls of the opening ceremony of the Beijing Olympic Games and the Olympic rings that have risen in the sky have given people a vivid LED popularization lesson. After the glory, what is the revelation of the LED industry, while we are encouraging the achievements, we can find and face up to the hidden dangers behind the industry, which are worth pondering.
The weakest upstream of the industrial chain
LED production processes include single crystal growth and epitaxial growth, chip fabrication and packaging. Single crystal growth and epitaxial growth are generally regarded as upstream of this industry, chip manufacturing is midstream, and packaging and application are downstream. The upstream of the industrial chain is characterized by technology and capital intensiveness, and the downstream entry threshold is relatively low. From the perspective of the industrial chain, China's LED substrate, epitaxy, and chip links are relatively weak.
Zhang Wansheng, a researcher at the 13th Research Institute of China Electronics Technology Group, stressed in an interview with China Electronics News that China's high-efficiency, high-reliability LED applications rely almost entirely on imported high-end epitaxial chips. Although it has made great progress and progress, it still stays at the middle and low level.
Peng Wanhua, secretary-general of the Optoelectronic Devices Branch of China Optical Optoelectronics Industry Association, also said that at present, high-performance LED chips and power LED chips are still available in China and still require a large amount of imports, which seriously restricts the entire LED industry. development of.
In the development of the LED industry and the improvement of the technical level, the LED epitaxy and chip industry play a decisive role. For the future how to upgrade and develop China's LED epitaxial and chip industry, Jiang Guozhong, general manager of Jiangxi Lianchuang Optoelectronics Technology Co., Ltd. believes that the key is to use domestic limited resources to establish a technology and talent through the coordination of industry alliances and relevant state departments. Comprehensive platform, independent innovation, development of China's LED extension and chip industry with independent intellectual property rights. It is necessary to vigorously develop the domestically-produced LED epitaxial and chip-packaged LED products in the entertainment, consumer, and sports markets, thereby driving our own LED epitaxy and chip development, and improving the overall technical level of domestic LED epitaxy and chips. Jiang Guozhong stressed.
Segmented application market to be developed
The LED industry has a special law: the price is reduced to 1/10 per 10 years, and the luminous efficiency is increased by 20 times. This makes the application range of LEDs expand rapidly, from the previous indicator lights, large screens, to lighting, Lighting, advertising and other fields.
Throughout the development of these years, we can easily find that the market application hotspots of LED are always changing constantly. In recent years, the conversion speed is increasing, but the packaging companies seem to be unable to grasp and catch up with the hot spots. Packaging companies can't keep up with the rapid transfer of hotspots in terms of technology, process and capacity.
Chen Hesheng, vice president of Jiangsu Wenrun Photoelectric Co., Ltd., stressed in an interview with China Electronics News that the LED packaging market is not lacking in hot spots, but most LED packaging companies lack the ability to predict or catch up with hot spots, and indeed no company has The ability to grasp all the market hotspots, but these hot spots have indeed been driving the overall promotion of the LED market. Market hotspots continue to prove that there are still many potential markets waiting for development. There is room for development in terms of technology segmentation and market segmentation. To put it another way, there is still a lot of room for differentiated competition. Chen Hesheng stressed.
The field and prospects of LED product application are infinitely wide, and it can be appreciated from the fact that the LED product application form of the Beijing Olympic Games is very rich. The application of LED products in the Beijing Olympic Games covers a wide range of product areas such as large-screen display, landscape lighting, LED lighting, landscape lighting, special lighting, information publishing services, advertising media, and stage background. Guan Jizhen, chairman of the LED Display Application Branch of China Optical Optoelectronics Industry Association and general manager of Beijing Sitong Intelligent Transportation Systems Co., Ltd., believes that innovation is an important factor in the development of the LED industry. Designers' innovation in the application design of LED products is an important prerequisite for industrial development. How to provide creative technology, innovative design and products to meet the needs of the LED industry requires serious thinking and active efforts. Guan Jizhen stressed. In fact, this also illustrates the importance of differentiated competition from one side.
Pay attention to the construction of public service platform
Due to the high international oil prices in recent years, LEDs that are cold-lighted are extremely exposed due to their energy-saving benefits. LED has become a hot industry because of its advantages of power saving, volume filiality and environmental protection. How to promote the healthy development of China's LED industry in the new market situation, and further promote the public platform construction of the LED industry is particularly urgent and important.
Experts gave advice on how to build a public platform for the LED industry. Peng Wanhua believes that it is necessary to strengthen construction from three aspects: first, the construction of LED product testing platform; second, the construction of LED application product research and development platform; third, the entire industrial chain of LED products, including raw materials, supporting parts, extensions, chips , public packaging for packaging products and various application product marketing markets.
The construction of the public service platform is inseparable from the support of the state. Tang Guoqing, director of the Semiconductor Lighting Professional Committee of the China Lighting Association, said in an interview with the China Electronics News that the current state support for the public service platform is not enough. Light emphasis is not enough, we still need specific implementation. It is not enough to rely on individual companies. It is necessary to have a state-supported and authoritative organization to take the lead in doing these things. Tang Guoqing believes.
Perhaps it is deeply felt that Liang Bingwen, chairman of Suzhou Naco Company, stressed in an interview with China Electronics News that in the new market and industrial environment, the public service platform should focus on providing R&D and testing for start-ups and small and medium-sized enterprises. Services such as testing, reducing the operating costs of SMEs, and at the same time undertaking the quality inspection and evaluation functions of products.
The US consulting firm Strategies Unlimited announced at the end of 2007 that the LED market will expand at an average annual rate of 17.6% between 2007 and 2011, and the market size is expected to expand to $9.4 billion in 2011. The advantages of China's development of the LED industry lies in its huge application market and strong production supporting capabilities. At present, for Chinese companies, it is a top priority to expand the scale and improve product quality and technology. Otherwise, after two or three years, what do we rely on to divide the market cake of 9.4 billion US dollars?
Experts hotly discuss the future of LED in the future. [Song Dinglong: China's lighting industry destiny thinking] [The world's tallest tower lighting (Photos)]
