What is the future trend of led floodlights?

LED lamps should be said to be the most promising lamps, energy saving and environmental protection, high luminous efficiency, long life and small size. I think it is the development trend of future light sources. With the rapid development of domestic LED market, more and more foreign enterprises are looking to China. Especially in recent years, the number of patent applications in LED field accepted by China has increased significantly year by year. According to a risk analysis report of semiconductor lighting patent provided by China National Intellectual Property Administration Development Research Center, by the end of 2008, 22 countries and regions around the world had applied for patents in China, and countries with obvious technological advantages applied for patents in China. The top five countries are Japan, South Korea, the United States, Germany and the Netherlands. Among them, Japan is far ahead in the number of patent applications with 1306, accounting for 24% of the total number of applications, and the other four countries account for 7%, 5%, 4% and 3% of the total number of applications respectively. In addition to the weak competitiveness of core technologies, the loose combination of Industry-University-Research is also the main factor that restricts the development of China's LED industry. A large part of LED patents in China are concentrated in scientific research institutes. For example, in the field of extension, the top three patents are Institute of Semiconductors, Institute of Physics of Chinese Academy of Sciences and Beijing University of Technology. In the field of chips, the top three are Semiconductor Institute of Chinese Academy of Sciences, Beijing University of Technology and Peking University. Compared with scientific research institutions, domestic enterprises apply for more utility model patents.
