With the further increase in the global LED market demand, the development of China's LED industry will face tremendous opportunities in the future, but at the same time there are unprecedented challenges. At present, LED core technology and patents are basically monopolized by foreign countries. It can be said that China's LED industry is painfully moving forward in happiness.
At present, the LED industry in the international perspective has initially formed an industrial structure centered on Asia, North America and Europe. It is patented by Japan's Nichia Chemical, Toyota Synthetic, American Corey, Puri and Germany's Osram. The core technological competition pattern, several major international manufacturers from Japan, the United States and Europe represent the upstream level of LED today and have a major impact on industrial development. This kind of influence is not only reflected in products and income, but more importantly, it is a monopoly on technology. More than 50 core patents are in the hands of these major manufacturers. China's LED is still at the lower end of the level, 80 products are concentrated in the landscape lighting, traffic lights and other application markets, the general lighting market is still in the promotion.
With the booming domestic LED market, more and more foreign companies are turning their attention to China. In recent years, the number of patent applications accepted in China's LED field has increased significantly year by year. According to the Research Report on the Risk Analysis of Semiconductor Lighting Patent in the Research and Development Center of the State Intellectual Property Office, 22 countries and regions have applied for patents in China. The top five countries are Japan, South Korea, the United States, and Germany. And the Netherlands. Among them, Japan has a number of 1,306 patent applications, accounting for 24% of the total number of applications. In terms of effective patents, the ratio of domestic patent applications to foreign patent applications in China is about 4:5. However, in these domestic patent applications, the Taiwan region has occupied a large share, and its effective invention patents account for 53. From the perspective of the distribution of industrial chains, foreign companies mainly have more patents in the field of chips and packaging. Half of the LED core inventions have filed patent applications in China, and foreign LED companies have mastered most of the core patent technologies.
The domestic LED industry in the twists and turns of the domestic LED industry started in the 1970s. After nearly 40 years of development, it has formed 7 national semiconductor lighting engineering industrialization bases in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang. The products are widely used in landscape lighting and general lighting. At present, China has become the world's largest producer of lighting appliances and the second largest exporter of lighting appliances. As of the end of 2011, there were more than 3,000 LED companies in China, of which only 140 were in the annual output value of over 100 million yuan. However, none of the 140 companies have annual sales of more than 1 billion yuan, and only a few of them have more than 500 million yuan.
What is the reason for China's LED industry to move forward in a difficult way? First, the industry lacks authoritative industry technical standards; second, the company's research and development is mainly concentrated in the downstream application areas, and the R&D investment in the upper and middle reaches is relatively high. less. While large foreign companies and some companies in Taiwan have monopolized most of the core LED technologies, mainland companies can only turn their attention to the downstream applications with lower technology content.
In addition to the core technology competitiveness of China's LED industry, the loose combination of production, study and research is also a major factor restricting its development. A large part of LED patents are concentrated in research institutes. In the field of extension, the top three patent holders are the Institute of Semiconductors of the Chinese Academy of Sciences, the Institute of Physics of the Chinese Academy of Sciences and Beijing University of Technology. In the field of chips, the top three are the Chinese Academy of Sciences. Semiconductor Institute, Beijing University of Technology and Peking University. Compared with research institutes, domestic enterprises apply for more utility model patents.
Compared with foreign companies, China's LED patent application is clearly at a disadvantage. According to the survey of the High-tech LED Industry Research Institute, China's LED-related patent applications totaled 26,071,000, of which nearly 50 were in the midstream and downstream packaging and application.
Although China has certain advantages in terms of electrodes, microstructures, reflective layers, substrate stripping, and bonding, most of them are peripheral patents, invention patents only account for 60, and international patents submitted through the Patent Cooperation Treaty (PCT) There are not many patents for applications and applications abroad.
In the face of international competitors, domestic enterprises should work harder. The first priority is to increase the intensity of independent innovation, focusing on the development of new technologies that can be widely accepted and recognized by the market; the second is to cooperate with foreign companies. On the basis of digesting and absorbing foreign advanced technology, we should strengthen imitation and innovation, improve the technical effect by improving the core patents of competitors, and apply for improved patents again. This is an effective way to avoid the risk of patent infringement.
Strengthening cooperation between industry, universities and research institutes is one of the effective ways to promote the rapid development of China's LED industry. Some domestic research institutions have certain research and development capabilities, while others have strong processing and manufacturing capabilities. Enterprises, enterprises and scientific research institutions should strengthen cooperation awareness, promote the transfer of innovation results of scientific research institutions to enterprises, and strive to cultivate a number of innovative leading enterprises with independent intellectual property rights.
In short, China's LED companies must pay attention to the early accumulation of intellectual property rights, learn to use science and technology to arm themselves, use patents to open up domestic and foreign markets, and turn traps into good market prospects, so that they can fly higher and more. far.
