Zusammenfassung:	PURPOSE: A method and apparatus for remotely controlling multiple lighting units are provided to obtain maximum power saving effect through a proper turning on/off control. CONSTITUTION: The voltage of a carrier is transmitted lower than 100mV. A communication terminal filters noises which is flown in through power frequency(60Hz) and other power lines using a filter and a digital gate. Only necessary carrier(50KHz) is created as 5 volt(Peak to Peak). The carrier is demultiplied through a frequency demultiplier. The divided frequency is transferred to the input terminal of an MCU(Micro Control Unit). Built-in program of the MCU recognizes the carrier, a control device performs communication with the communication terminal.
