Guangdong seizes the commanding height of LED visible light communication

The scale of semiconductor lighting industry in Guangdong Province accounts for about 70% of the country's total. It has leading advantages in respect of government, industry development, technology foundation, and market applications. It is hoped that the team of Academician Jiangxing Jiang will seize the opportunity of the province's full implementation of innovation-driven development strategy, and actively Our province has carried out technical cooperation and exchanges, and has established the National Visible Communication Technology Innovation Alliance in Guangdong to promote the industrialization of visible light communication technology in Guangdong. Huang Ning, director of Guangdong Provincial Department of Science and Technology, said at a meeting with his predecessor leader of the Visible Light Industry Communication Technology Innovation Alliance and the former president of the Information Engineering University of China’s People’s Liberation Army’s Information Engineering University, Jiang Jiangxing, that the Guangdong future will rely on its own LED industry. Advantages and occupy the commanding heights of visible light communications, the development of the “trillion-dollar” industry.

During the talks, Jiang Jiangxing Academician fully recognized Guangdong's sound semiconductor industry chain and said that he would consider jointly working with the Guangdong Science and Technology Department and the Guangdong Semiconductor Lighting Industry Co-Innovation Center to promote the rapid operation of China's visible light communication industry technology innovation alliance and promote the development of the visible light communication industry. The two sides also agreed to hold a conference on visible light communication technology in the near future to jointly promote the rapid industrialization of the technology.

It is understood that visible light communication technology utilizes high-speed light and dark flicker signals emitted by fluorescent lamps or LEDs that cannot be seen by the naked eye to transmit information. A high-speed Internet wire device is connected to a lighting device, and a power plug can be inserted and used. A system made using this technology can cover the range of indoor lights, and the computer does not require wires to connect, and thus has a wide range of development prospects.

At present, visible light communication has become a hotly contested field in the field of international communication research among countries such as the United States, Japan, and Europe. After China's 863 Plan deployed visible light communication technology in 2011, after more than two years of scientific and technological research, it has expanded its modulation bandwidth. A number of important research results have been achieved in terms of real-time transmission rates, converged network architecture, and so on.

LED lighting optical wireless communication is still in the exploration and start-up stage at home and abroad, but it has shown attractive application prospects. It can not only be used for indoor wireless access, but also can provide a brand-new for mobile navigation and positioning of urban vehicles. method. Basically, LED lights are used in automotive lighting. They can form communication links between cars and traffic control centers, traffic lights to cars, and cars to cars. In the future, it will also be possible to use the visible light communication technology to access the Internet and make telephone calls on the aircraft.

According to industry insiders, Guangdong, as a pioneer in scientific development, has gathered more than half of the leading companies in the communications and lighting industries in the country and has a good LED hardware industry base. The Provincial Science and Technology Department's exchanges with the Qujiangxing academicians will further promote Guangdong to seize the commanding heights of the visible light communication industry and effectively promote the transformation and upgrading of the entire LED industry. It can be said that currently introducing, nurturing and developing visible light communication will help strengthen the traditional leading advantages of Guangdong's LED industry, help foster the development of Guangdong's LED industry, create new growth points, and facilitate the deep integration and development of LED industry and related industries. The significance of strategic development.
