The electronic ballast includes two parts: traditional electronic ballast and power line carrier. The power line carrier possesses central processor circuit, transceiver, high pass coupling circuit, input/output control circuit and current detection and decision circuit. In operation, the current detection and decision circuit detects the output current of the inversion main circuit in the electronic ballast to determine whether ballast and lamp is in normal operating state or abnormal operating state. Based on the said state, logic level '1' or '0' is output to central processor circuit, which controls on/off of electronic ballast by outputting '1' or '0' to input/output control circuit. Thus, operating state of HID electronic ballast is controlled and monitored in communication mode of power line carrier. The invention reduces number of control wires, lowers wiring cost as well as lays foundation for intelligentized lighting network.
