1. A system for controlling LED with power line carrier, comprising:

  • at least a luminous device for illumination, containinga terminal microprocessor for data and signals processing and calculation;

    a terminal power line carrier module, which is coupled with the terminal microprocessor, for data modulation and demodulation;

    a terminal power supply module, which is coupled with the terminal microprocessor, for providing static power supply;

    at least a LED, which is coupled with the terminal microprocessor and the terminal power supply module;

    at least a LED driving module, which is coupled between the terminal microprocessor and the LED, and between the terminal power supply module and the LED, for regulating electric current and voltage, protecting the LED, and controlling the LED;

    a host controller for controlling the luminous device, containinga host microprocessor for signals and data processing and control;

    a host power line carrier module, which is coupled with the host microprocessor, for data and signals modulation and demodulation;

    a host power supply module, which is coupled with the host microprocessor, for providing static power supply;

    a communication and control module, which is coupled with the host microprocessor, for providing user with control capability; and

    an electric power conductor, which is connecting with the terminal power line carrier module, the terminal power supply module, the host power line carrier module, and the host power supply module, for carrying electric power and signals;

    whereby the data and signal transmitting between the host controller and the luminous device are all through the electric power conductor, and do not need any extra transmission line.
