China's LED patent technology and other factors seriously hamper the development of China's LED outdoor lighting. In the highly competitive LED lighting market demand, only by mastering LED patents and technologies, can we better ensure product quality and performance. LED (Light EMI Dielectric Diode) is a solid-state semiconductor light-emitting diode that converts electric energy into visible light, directly and efficiently converts electricity into light, and has a service life of tens of thousands of hours to 100,000 hours. It is composed of wafers and epoxy resin, can work at low temperature and has good directionality of light sources. It is used in fields such as landscape, security, special and general lighting, and the market potential is beyond measure. Today, LED outdoor lighting is high. I. Analysis of Current Status of LED Outdoor Lighting in China The global advocate of low-carbon life, energy-saving carbon reduction LED semiconductor lighting has become the "darling" of the times. LED is a new generation of environmentally-friendly light sources that attract worldwide attention. Its advantages of high brightness, low heat, long life, and non-toxicity are known as the most developing green lighting sources in the 21st century. China's LED lighting industry started in the 1970s and has been developing for more than 40 years. China has now become the world's largest producer of lighting appliances and the second largest exporter of lighting appliances. LED, as the leading industry for outdoor lighting in the 21st century, also has its shortcomings. 1. Attention and application of LED outdoor lighting at home and abroad In 1998, Japan’s Ministry of International Trade and Industry issued the first issue of the “21st Century Light Plan†to make the world’s first attention to LED, and its government also stimulated the development of LED technology through fiscal subsidies, tax incentives, and loan concessions. In 2005, the U.S. government launched the "Next Generation Lighting Plan" to implement tax incentives for the LED industry. The large-scale LED street lighting renovation project in Los Angeles has promoted the use of LED street lamps. In China's Outline of the National Medium and Long-Term Scientific and Technological Development Plan, LED lighting and other semi-conductor lighting products have been explicitly included in the "key areas and priority themes." China's Ministry of Science and Technology has also launched the "Ten Thousands of Cities" semiconductor lighting project for three years. It plans to install up to one million LED street lamps, and the demonstration project of "1,000 Miles" LED street lamps in Guangdong has accelerated. The "Guangdong Provincial LED Street Lamp Local Standard" has also been introduced. LED street lamps have received strong support from the government and other relevant departments. LED outdoor lighting is not only widely used in urban landscapes, but also used in tunnels. At present, the highest attention rate is the application of LED street lamps. Los Angeles will install 140,000 LED street lights within five years, while the two cities of Pennsylvania, Ambler and Sunbury, will all be replaced with LED street lights. LED lights are commonly used in other countries. , such as Japan, South Korea and so on. In China, Dongguan plans to use LED street lighting for all three years, and Hainan plans to achieve five years. Beijing Olympic Games, Shanghai World Expo, Guangzhou Asian Games infrastructure construction uses a large number of LED outdoor lighting, such as the main venue of the Asian Games venue of the Guangzhou Asian Games, and the surrounding roads have built a total of 70,000 LED street lights, Foshan sub-race stadium Lingnan Pearl Stadium 12 The main road, 12,000 high pressure sodium lamps were all converted into LED street lights. According to data from the LEDinside Research Department, in 2010, the number of global LED street light fixtures will reach approximately 870,000, of which the LED street light market in China will increase by 60% and reach over 400,000 baht. In fact, the annual demand for street lamps in China is more than 20 million, and it is increasing. Experts predict that the global LED street lamp shipments will reach 8 million baht in 2011 and the penetration rate will be 8.5%. Street lamps account for about 59% of the global market share. According to the statistics of the Senior Industry LED Industry Research Center (LIRC), it is expected that the installation of LED street lamps will reach 1.12 million baht in 2009-2011. According to this, China's LED outdoor lighting industry is facing unprecedented opportunities and huge market potential, and the development prospects are very optimistic. 2. Current development status of China's LED outdoor lighting industry (1) Foreign basic monopoly LED patents, less domestic patents Internationally, the leading manufacturers of LED patents are Nichia, Toyoda Gosei, Cree, Phi Lips Lumileds, and Osram. It is reported that among the patent-related countries for LED applications, Japan accounts for 27.9% of the world, and China accounts for only 9.34%. The number of patents in China is far lower than that of Japan and the United States. Especially in the field of epitaxial technology and chip structure in the upper reaches of the LED industry chain, the number of patent applications is even lower than in Germany and Taiwan. Foreign companies attach great importance to patents in terms of maintenance, such as Japan's Nichia had tried to monopolize the blue LED market with patents, use various means to maintain the blue LED market, and it had no external sales for the successful development of GaN materials. Or only sold in Japan. (2) Foreign LED technology is higher than China At present, the best-developed countries in the LED industry are Japan, the United States, and Germany. Taiwan in China also has a good development. Taiwan’s market share only ranks in Japan and ranks second in the world. Taiwan once beat Japan with low-priced chips and low-priced products, forcing Japan to develop high-priced chips and high-priced products, and Taiwan seized the opportunity to combine the experience of many years to develop downstream packaging, upper-middle-stream epitaxial wafers and chips. And continue to expand. Even so, Taiwan's LED technology still has a huge gap with Japan, Europe and the United States. China's mainland is even more difficult to achieve, especially in LED phosphor material production and design, packaging technology, ultra-low technology content, as a large country of LED production and demand consumption, the development of China's LED lighting industry still needs to break away, seek more With the exchange of communication opportunities with foreign countries and can form a standardized brand effect, will let the LED outdoor lighting industry go further. China's LED outdoor lighting technology content is not high, mainly in the material production and design, epitaxial materials, chips, packaging, the whole lamp development and other aspects out of touch, the upper, middle and downstream industrial chain integration is not in place, and chip development process, chip Packaging and other core technologies are also in the low-level development stage. China's LED industry is mostly concentrated in downstream enterprises with low technological level, small scale, backward technology, and lack of independent innovation capability, which also provides extensive development space for China's LED lighting industry technology. LED lighting industry patents and technologies have become a “double-edged sword†for the development of LED outdoor lighting in China. The patents that are difficult to break through are LED patents. The good news is that foreign advanced technologies can be learned through various means. For example, the “Second LED Drive Technology Symposium†organized by the Big Bit Consulting Group was held in Shenzhen at the end of October, which will bring valuable learning opportunities to more than 600 companies participating in the conference, as the meeting targeted domestically. External experts have made a profound speech interaction on LED hot topics, such as LED driving power, thermal dimming, and security, which contributes to the development of LED outdoor lighting (the core technology lies in safety and thermal dimming). enhancement.
