LED lamps, LED display as an energy-efficient lighting equipment has gradually come into our lives. But did you know, the light emitted by the LED can be connected to broadband networks, which in the current scientific research has become a reality. Reporters learned yesterday from the Institute of Semiconductors, Chinese Academy of Sciences, the Institute for the study of semiconductor lighting information network has made a major breakthrough. , LED
Lamp can be wireless Internet access
A laptop computer placed under light exposure, there is no cable connection, no wireless card, but online video is still smooth playing ... this is what happened yesterday in the Institute of Semiconductors of semiconductor lighting and museum information model scene. Why is this the case? Optical Systems Laboratory Dr. Duan Jingyuan reaching a mean, it's secret lies in the ceiling, the blue LED lights.
He explained that the network signal is transmitted to the computer through the light. In this way, the current maximum transmission rate of the Internet can reach 2 trillion per second.
In addition to connect to the network outside, LED lights also serve as a commander of household appliances. The Institute's Dr. Chen Xiongbin, at present they have implemented a variety of electrical switches on the control and regulation. These two technologies have been the Expo Center and Shanghai Eco-Home Air Museum for the show.
High-speed switches to transmit information
LED light is how the light signal and control signal transmission network it? Experts, LED lamp is new lighting, traditional lighting and different it is not only power, but also through high-speed switching, given the modulated signal, the information and instructions to complete the transfer. ,
Non-stop action will not affect the normal switching of lighting used? The answer is no. R & D personnel per second switching speed of up to 200 million times, the naked eye can not feel.
Flights to overcome the problems the Internet
It is now easy to enjoy the wireless network service, it is also the constant fear that it generates electromagnetic waves may adversely affect the human body, and the Internet with a green LED light was able to completely eliminate this concern. No electromagnetic waves would not have been caused by interference with surrounding electronic equipment, aircraft also wireless Internet access problems will be solved, even in the water, shone a bunch of LED lights, you can complete the network signal high-speed transmission.
Experts, and compared the current wireless technology, LED lighting is only a potential of the Internet stocks. Because of its special information transmission, in the future on a G per second access speed. It is understood that the United States, Japan and Europe have begun on the development of LED technology, wireless communication, this may become an important direction for future technology development.
