LED lighting communication is correct

It is a common knowledge to call and surf the Internet when you are flying. But one day, you only need a LED light above the seat to use your laptop to browse the web and download videos. influences. The Semiconductor Lighting Information Network based on the principle of LED optical wireless communication has made a major breakthrough.

At the Semiconductor Lighting and Informatization Demonstration Hall of the Institute of Semiconductors of the Chinese Academy of Sciences, a laptop computer has neither a network cable nor a wireless network card, but the network video is playing smoothly on the computer screen; some electrical appliances such as televisions, home theaters, microwave ovens , spherical camera, electric curtains, etc., people are far away, just operate the mobile phone in their hands, the TV will start to play the program, the microwave oven lights up, even the camera adjusts the focus, the lens zooms in and out, etc. is very "small" action Can be achieved. Associate Professor Chen Xiongbin from the Institute of Semiconductors of the Chinese Academy of Sciences said that the mystery of realizing this "miracle" lies in the LED lights embedded in the ceiling.

In addition to lighting, the original LED light can also be used for communication and control. The principle is to control the LED light through the signal pulse, so that the LED light flashes at a very fast frequency to realize signal transmission. This high frequency flashing It is undetectable by the human eye, so the LED light can be illuminated and signaled.

"It is not a dream to freely access the Internet in the future." Simply add a central controller to the aircraft and send the received satellite signals to the LED reading lights on the passenger's seat. This makes the ordinary lights a network. The access point, the laptop placed underneath it can access the Internet, and passengers can surf the Internet to send away the lonely journey. The aircraft can't make calls and surf the Internet because it is worried that electromagnetic radiation will affect the safety of the aircraft. The wireless communication technology of LED lights can completely eliminate this concern because it does not emit electromagnetic waves and is a very secure wireless communication system.
