Recently, at a photonics industry technology forum held in Jiangsu, experts and scholars at the meeting expressed deep concern about the intellectual property barriers that domestic LED companies will face when they go abroad. They believe that domestic enterprises will not step up their core with independent intellectual property rights. The research and development of technology, more patents, then, not long after, when domestic LED companies mass production, especially exports, will certainly encounter foreign patent barriers, repeat the patent trap of DVD and mobile phones, that is, the profit of the big head is patented The foreign manufacturers take away, they can only make hard money.
LED (short for "light-emitting diode" in English) is a semiconductor lighting technology. The light-emitting device can directly convert electrical energy into visible light, and has the advantages of low working voltage, low power consumption, high luminous efficiency and long life. Compared with traditional incandescent lamps and fluorescent lamps, it can save more than 90% of electricity, but its life span is 10 times that of fluorescent lamps and 100 times that of incandescent lamps. In terms of environmental protection, it also avoids secondary pollution of mercury leakage from fluorescent tubes. In the face of such a huge city mockery, global companies and R&D institutions are in action. At present, Japan, the United States and Germany have taken the lead and have a leading number of patents. Especially the most popular technical methods are abroad. The manufacturer applied for a patent. This can not help but remind people of the experience of domestic DVD companies.
Domestic DVD companies once occupied 80% of the world's share in the era of stand-alone applications. However, under the aggressive attack of foreign patent holders and related companies holding patent sticks, this pattern is like a flash in the eye. With the popularity of DVD technology in digital TV, computer and car audio and video systems, domestic DVD technology is becoming more and more mature, but many foreign patent holders rely on patents to obtain market monopoly status, ignoring patent regionality and rights exhaustion rules, and unreasonably rejecting Licensing, setting a high license fee, forcing downstream companies to purchase a package of licenses from the patent pool administrator at a high price to obtain excess monopoly profits. The patent abuse policy of foreign patent holders not only damages the market opportunities of Chinese enterprises, but also causes huge losses to the interests of domestic related enterprises. For example, Sichuan Dingtian Group invested 200 million yuan to build a DVD industrial park. After spending a lot of manpower and material resources to obtain relevant patent licenses, it was completely defeated by 3C's unreasonable martyrdom.
Nowadays, the application bottleneck of LED technology is mainly that the luminous efficiency can not keep up with incandescent lamps and fluorescent lamps. Once the technology breakthroughs and effectively reduce the manufacturing cost, LED can replace traditional lighting and trigger a revolution in global lighting technology. Some people have calculated such an account. If one-third of domestic lighting power uses semiconductor lighting, it will save 80 billion kWh per year, equivalent to the annual power generation of a Three Gorges power station. In fact, LED has penetrated into every aspect of social and economic life. Like the red and green signal lights on the streets of major cities in China, large outdoor display screens, billboards, and backlights for mobile phones and digital cameras, car dashboards, etc. all use LED technology.
At present, domestic LED companies are basically application-oriented enterprises. There are few companies that are really engaged in the research and development of chip core technology. The patents they own are mainly concentrated in the application field, with only a total of more than 100. The products are basically not exported, but are produced for their own use. Once you want to enter the international market, you will encounter foreign patent barriers. It should be said that there is still room for independent innovation in the field of LED in China. Therefore, it is imperative for domestic enterprises to step up their independent research and development. For example, Jiangsu Aolei Optoelectronics plans to achieve technological breakthroughs in 2010 through cooperative research and development, so that the luminous efficiency of LEDs reaches the level of fluorescent lamps. Some experts pointed out that LED technology can complement the development of solar energy sources, and integrate its industry resources to develop its own characteristics in the development of LED technology. Because the LED uses a low-voltage DC of about 5 volts, it needs to be converted by alternating current, and the electricity generated by the solar energy is direct current, and the LED is directly available.
