LED communication technology - a new direction for future lighting applications

　　Can not call time on an airplane, the Internet, which is well known common sense, but someday, you only need one LED lights illuminated above the seats, you can browse the Web with a laptop, downloading video, but the safety of aircraft without the slightest affected. Institute of Semiconductors LED-based optical wireless communication principle of "semiconductor lighting Information Network" has been a major breakthrough.

　　In the Institute of Semiconductors, semiconductor lighting and information technology demonstration hall, a laptop neither network cable, no wireless card, but on the computer screen but in the smooth playback of online video; some electrical appliances such as televisions, home theater, microwave , dome cameras, electric curtains, etc., who left very far, just operating the hands of mobile phones, televisions started to broadcast programs, microwave lights work, and even adjust the focal length of the camera lens zooms closer and so very "small" action can be realized. Research Associate, Institute of Semiconductors Xiongbin introduced mysteries to achieve this "miracle" lies embedded in the ceiling LED lights.

　　In addition to the original LED lights lighting lighting, but also for communication and control, the principle is controlled by the signal pulse LED lights, the LED lights at great frequency kept flashing light and shade, for signal transmission, this high-frequency flicker the human eye can not detect, so LED lamps can be illuminated, signaling correct.

　　"The future of Internet freedom in the aircraft is not a dream", just install a central controller on the plane, will receive the satellite signal to the LED reading lights on the passenger seat, so a lamp lights has become a common network access point, placed beneath a laptop can access the Internet, passengers can surf the pass lonely journey. Can not call on the plane, the Internet, because the fear of electromagnetic radiation affecting the safety of aircraft, and the LED lights wireless communication technology can completely eliminate this concern, because it does not transmit radio waves, is a very secure wireless communication systems.
