Research and development of LED light access broadband network in China

LED lights, LED display, led as an energy-saving lighting equipment has gradually come into our lives.　　But the light emitted by LEDs can connect broadband networks, which has become a reality in current scientific research.　　Reporter from the Institute of Semiconductor Research learned that the semiconductor lighting information Network has made a major breakthrough in the light can be wireless internet access to become a reality. A notebook computer under the illumination of the light, no network cable connection, no wireless network card, but the smooth network video is still playing ... This is the scene in the semiconductor lighting and informatization Demonstration Hall of the Chinese Academy of Sciences, which happened today. Its secret lies in the blue LED lights on the ceiling. The network signal is transmitted through the light to the computer. In this way, the current maximum transmission rate on the Internet can reach 2 trillion per second. In addition to connecting the network, LED lights can also serve as the commander of various household appliances. Dr Chen Xiongbin, of the Institute, has now achieved control over the switching and regulation of multiple electrical appliances. Cai Wenqing
