The 60th anniversary of the founding of New China, the reform and opening up has also reached the 31st year, the traditional lighting industry in China has a history of more than 10 years, and the development of China's semiconductor lighting "positive history" (from the start of the national semiconductor lighting project in 2003) Less than 10 years. However, in this golden development period of less than ten years, China's semiconductor lighting industry has achieved remarkable achievements, and presented a sacrament for the 60th anniversary of the country's birthday! The development of general lighting and functional lighting has witnessed the country's 60-year great change. It is the projection of the country's 60 years of development in the sea. On the occasion of the 60th anniversary of the founding of New China, Wu Ling, Secretary General of the National Semiconductor Lighting Engineering R&D and Industry Alliance, conducted a systematic analysis and reflection on China's semiconductor lighting industry.
From nothing to nothing, from import to domestic semiconductor lighting industry to make great changes
The history of China's semiconductor lighting industry has not been long-lasting, but it has made very gratifying changes. Before 2002, domestic Blu-ray chips all relied on imports. In 2003, China began to produce independently. By the end of 2008, the localization rate of LED chips in China reached 49%, and the localization rate of LED devices reached 90%.
Unfortunately, domestic LED chips are mostly used in low-end products, while the performance of high-power high-brightness LED chips is far behind the international level. More than 80% of high-power HBLEDs are still imported. At the end of the "fifteenth" (2005), the domestic chip packaged white light after the light effect is only 30lm / W @ 350mA. In August 2006, the Ministry of Science and Technology launched a major project of “Semiconductor Lighting Project†in the new material field of the “Eleventh Five-Year Plan†863 Program, arranging a funding of 350 million yuan, a breakthrough in the core technology of the semiconductor lighting industry chain and key technologies supporting the industry. Fully deployed. Now, the domestic LED chip package has a white light effect of 90lm/W@350mA, and the mass production level is expected to exceed 100lm/W next year. The laboratory level reaches 130lm/W, and the highest level of industry research and development reported has been Cree's 161 lm/W.
In addition to luminous efficiency, the biggest problem in the technical segment of China's semiconductor lighting industry is that the reliability and consistency of the products are relatively poor, and the mass production capacity is also different from the international level. However, it is gratifying that China has developed rapidly in these links, and the gap with international manufacturers has gradually narrowed.
In addition, China's semiconductor lighting companies have increased rapidly. By the end of 2008, the total number of enterprises has exceeded 3,000. Compared with international big factories, these enterprises are relatively small in scale and the overall competitiveness of the industry is not enough. However, in the field of multiple functional lighting, with the courage and innovative spirit of the company's courage to try, China has already ranked in the forefront of the world. In the field of general lighting, with the participation of traditional lighting manufacturers in the LED R&D team, LED general lighting has become an industry with large investment and high risks, but the innovative spirit of Chinese enterprises will be the key to determining the success or failure of the industry.
Behind the inevitable factors of industrial progress
Under the background of globalization that emphasizes energy conservation and environmental protection, the semiconductor lighting industry faces a golden opportunity for development. The public awareness of environmental protection has increased. Governments have issued a series of energy conservation and environmental protection policies. The development of semiconductor lighting is the trend of the times, and it is the social environment and economic development. The inevitable result. In addition to the time factor, the progress of China's semiconductor lighting industry is closely related to the joint efforts of enterprises, governments and industry organizations.
First of all, the R&D strength of enterprises is the key to LED technology advancement, light efficiency improvement and performance improvement. The unparalleled sense of innovation of LED companies in China has enabled the industry to continuously discover new growth points. Secondly, the government's promotion policy for the semiconductor lighting industry is enough to attract the world's attention. From the "10th Five-Year" project to the "Eleventh Five-Year Plan" 863 project, a large number of R&D funds have brought a spring breeze to the booming industry; The introduction of a large number of classic projects and demonstration projects is an indispensable driving force for industrial development. In addition, industry organizations including the National Semiconductor Lighting Engineering R&D and Industry Alliance (CSA), local alliances, lighting associations, people of insight and technology workers, and friends from the investment community constitute an organic driving force.
Difficulties in the semiconductor lighting industry
Government support and huge market demand in the context of energy conservation and environmental protection are a rare historical opportunity; China's abundant raw material resources and industrial base, as well as the established international exchange and cooperation environment, have provided favorable conditions for the development of the semiconductor lighting industry. At the same time, we should be soberly aware that there are still a series of huge challenges to be addressed from the R&D level to the enterprise level to the industrial environment. One of the industrial chain (ie, equipment, raw materials and epitaxial chips) (ie high-end application products) has become a key link that restricts China's industrial development. In addition, the scale of the enterprise, product grades, testing standards, policy support, etc. also need the joint efforts of the industry, and constantly improve and improve. In general, there are many problems from the early investment and construction of the factory, the formulation of industrial development strategies, the promotion and application in the later period, and the occupation of major demonstration projects.
Early development strategy: each of them has a serious problem of low level of repetition
First, China has a vast territory. Each province and city has its own development ideas. It is difficult to cultivate a national leading brand enterprise and it is difficult to form an international influence.
Second, the LED industry is characterized by low technology thresholds, low investment, and low risk in the middle and lower reaches (even upstream), resulting in a large number of enterprises entering, but low-level redundant construction, and even high-level (referring to the upstream field) low-level redundant construction problems. serious.
Third, the emerging industry fully experienced market competition is the only way to develop. The excessive intervention of the government will lead to unfair competition, thus hindering the sound development of the industry.
Fourth, China's semiconductor lighting industry talent gap problem is outstanding, talent shortage, insufficient technical support, human resources can not keep up with the development of the industry, especially the regional development concept is aggravating the shortage of core talent.
Late promotion and application: the lack of standards is not worth the loss of consumer confidence
First, the customization of standard specifications cannot keep up with the requirements of industrial development. The lack of standard norms is a situation in which industrial development is in disorderly competition.
Second, some localities have introduced local regulations and provided guidance to the industry. However, due to the wide variety of semiconductor lighting products, there are many constraints on the terminal products. Therefore, it is difficult to standardize the quality of the products by simply setting a certain number of indicators.
Third, many local governments have demonstrated enthusiasm and lack of product testing to ensure product quality, which has led some application projects to fail and hit consumer confidence. For emerging industries, consumer confidence is crucial, and once it is affected, it is difficult to recover.
Until the top three Chinese semiconductor lighting industry is at a high level
The opportunities and challenges of the semiconductor lighting industry coexist. It is not only a revolutionary technology, but also a global industry. As long as all parties work together to break through the development of the industry, semiconductor lighting should be visible to the future and can be done in the future. Strategic industry direction.
China has become a fertile ground for the world's attention and expectation. China's development is not only manifested in the economic take-off, but also provides a peaceful, greener and more harmonious home for the people to live and work in peace and contentment. Although the environment for the development of China's science and technology industry is still in the "industrial" development stage, industrial support, industry and commercial operation are not perfect, and China's semiconductor lighting industry is late than international advanced countries, but it is believed in national policy and industry. With the joint efforts of the industry, the academic community, the investment community and all consumers who are keen on energy conservation and environmental protection, China's semiconductor lighting industry will surely rank among the top three in the world!
