Integrated System Of White Led Visible-Light Communication And Power-Line Communication


White LEDs offer advantageous properties such as high brightness, reliability, lower power consumption and long lifetime. The biggest potential application for white LEDs will be general illumination and lighting. Indoor wireless optical communication systems employing white LED lighting have been proposed. This system will enable high QoS by the high power from this lighting equipment. But, it is difficult for existing offices communication using existing power-line is proposed. This system is emitted as visible-light from LED lighting according to the transmitted signal waveform without demodulating the signal from the power-line. This system is expected to be applicable from the existing illuminant easily like exchanging electric bulbs. This integrated system will surely have a big impact as a new signal transmission system and its economical effect will be great. The basic performance of this system is analyzed. The actual system is built and its feasibility is shown through experiments
