Today, China has become an important middle and low-end LED packaging production base in the world. It is estimated that China's LED industry will reach 100 billion yuan in 2010. However, the core technologies of the current LED lighting industry are mostly controlled by foreign companies. LED floodlights, upstream core patents are mainly concentrated in the hands of large companies such as Nichia Chemical (Japan), Osram (Germany), Kerry (USA), General Electric (USA), Toyota Synthetic (Japan) and Samsung (Korea). Companies from the US, Japan and Europe not only occupy most of the market share, but also own 85%-90% of original invention patents in the upstream area of ​​the LED lighting industry chain.
According to the "LED Industry Patent Situation Analysis Report" jointly released by the Guangdong Provincial Intellectual Property Office and the Guangdong Provincial Information Industry Department, Japan’s exclusive patents in the application of LED applications account for 27.9% of global patents, while China only accounts for 9.34%. Relevant surveys show that packaging is the main research and development and application field in China, and the number of patent applications accounts for 39% of the total. Others are application technology, epitaxial technology, chip technology, white light technology and substrate technology. The related patents mainly involve the preparation of LEDs. Methods and equipment.
2009 LED related invention patent
The United States, Japan and Europe: There are about 20 chip companies, LED floodlights, and more than 300,000 patent applications, accounting for 85%-90%.
China: There are about 62 chip companies, and about 30,000 patent applications are filed, less than 10%.
Semiconductor promotion process in developed countries
United States: From 2006 to 2011, $50 million was allocated annually for technology development for the Semiconductor Lighting Program (NGLI). In 2010, 55% of incandescent and fluorescent lamps in the United States will be replaced by semiconductor lamps, saving $35 billion annually.
Japan: The second phase of the semiconductor lighting program was implemented in 2003. It is expected that the luminous efficiency of white LEDs will reach 120lm/w in 2010, and by 2020, it is expected to replace 50% of incandescent lamps and all fluorescent lamps. LED flood light
Europe: It is planned to use LEDs with a luminous efficiency of 200 lm/w by 2020 and a 20% reduction in energy consumption.
1. Security: UAV signal jammer can effectively block the communication signal of UAV, thus preventing potential security threats. The illegal use of drones has become a serious problem in modern society, and drone signal jammers can help protect key facilities, activity places and people from the potential harm of drones.
2. Efficient and reliable: UAV signal jammer adopts advanced technology, which can jam UAV signal quickly and accurately. It can quickly identify and interfere with the communication frequency of UAV in a short time, making it impossible to receive or send signals, thus quickly and effectively solving the threat of UAV.
3. Flexible and diverse: UAV signal jammer has many models and functions, which can be selected according to different needs. Whether it is necessary to jam a single UAV or multiple UAVs, UAV signal jammer can provide corresponding solutions. In addition, there are some UAV signal jammers with positioning function, which can help users accurately locate the position of the UAV.
