The status quo of LED industry: 'Happy' and 'painful'

With the further increase of LED market demand, China's LED industry will face great opportunities in the future, but there are also challenges. At present, LED core technologies and patents are basically monopolized by foreign countries. It can be said that China's LED industry is moving forward in pain. At present, the LED industry from an international perspective has initially formed an industrial pattern centered on Asia, North America and Europe, with Japan's Japan-Asia chemical industry and Toyota synthesis, the technology competition pattern with Corey, purui of America and Osram of Germany as the patent core, several international manufacturers from Japan, America and Europe represent the current upstream level of LED, it has a significant impact on industrial development. This kind of influence is not only reflected in products and income, but also in the monopoly of technology. More than 50 core patents are in the hands of these major manufacturers. However, China's LED is still at a relatively low level, with about 80 products concentrated in landscape lighting, traffic lights and other application markets, and the general lighting market is still being promoted. With the vigorous development of the domestic LED market, more and more foreign enterprises turn their attention to China. In recent years, the number of patent applications accepted in the LED field in China has increased significantly year by year. According to the Development Research Center of the State Intellectual Property Office in the 'semiconductor lighting patent risk analysis research report', 22 countries and regions have applied for patents in China, the top five countries are Japan, South Korea, the United States, Germany and the Netherlands. Among them, the number of 1306 patent applications in Japan is far away, accounting for of the total number of applications. In terms of valid patents, the ratio of domestic patent applications to foreign patent applications in China is about 4:5. However, in these domestic patent applications, Taiwan occupies a large share, and its effective invention patents account for 53. Judging from the distribution of the industrial chain, foreign companies mainly have more patents in the fields of chips and packaging, and half of the LED core inventions have filed patent applications in China, foreign LED enterprises have mastered most of the core patented technologies. The domestic LED industry, which moves forward in twists and turns, started in 1970s. After nearly 40 years of development, it has now formed seven national semiconductor lighting engineering industrialization bases in Shanghai, Dalian, Nanchang, Xiamen, Shenzhen, Yangzhou and Shijiazhuang, products are widely used in landscape lighting and general lighting fields. At present, China has become the world's largest producer of lighting appliances and the second largest exporter of lighting appliances. By the end of 2011, there were more than 3000 LED enterprises in China, of which only 140 had an annual output value of over yuan. However, among these 140 enterprises, none of them has an annual sales of more than 1 billion yuan, and only a few have more than 0. 5 billion yuan. What makes China's LED industry move forward in difficulty? The first reason is the lack of industry technical standards in the industry; Second, the R & D of enterprises is mainly concentrated in the downstream application fields, and the R & D investment in the upper and middle reaches is relatively small. However, large foreign companies and some enterprises in Taiwan have already monopolized most of the LED core technologies, and mainland enterprises can only turn their attention to downstream application markets with low technology content. In addition to the weak core technology competitiveness of China's LED industry, the loose combination of production, teaching and research is also a major factor restricting its development. A large part of LED patents are concentrated in scientific research institutes. In the field of extension, the top three patents 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 Institute of Semiconductors of the Chinese Academy of Sciences, Beijing University of Technology and Peking University. Compared with scientific research institutions, domestic enterprises apply for more utility model patents. Compared with foreign companies, China's LED patent application is obviously at a disadvantage. According to a survey by the high-tech LED Industry Research Institute, China's LED-related patent applications totaled 2. There are 60. 71 million pieces, of which nearly Are patents in packaging and application in the middle and lower reaches of the industry. Although China has certain advantages in electrodes, microstructures, reflective layers, substrate stripping, and bonding, most of them are peripheral patents, with only of invention patents, and through the Patent Cooperation Treaty (PCT) There are not many international patent applications submitted and patents applied abroad. In the face of international competitors, domestic enterprises should work harder. The first is to increase the intensity of independent innovation, focusing on the research and 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 technologies, we should strengthen imitation and innovation, and improve the core patents of competitors to improve their technical effects; The third is to apply for an improved patent, which is an effective way to avoid the risk of patent infringement. Strengthening industry-university-research cooperation 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 some enterprises have strong processing and manufacturing capabilities. Enterprises, enterprises and scientific research institutions should strengthen their sense of cooperation, promote the transfer of innovative achievements of scientific research institutions to enterprises, and strive to cultivate a number of innovative leading enterprises with independent intellectual property rights. In a word, LED enterprises in our country must attach importance to the early accumulation of intellectual property rights, learn to arm themselves with science and technology, exploit domestic and foreign markets with patents, and turn traps into good market prospects, only in this way can we fly higher and further.
