<p>A light control system using multi communication is provided to transmit and receive data independently or at the same by using a wireless communication module, a power line communication module, and a wireless communication module. A light control system using the multi communication includes a receiving device(300), a transmitting device(100), N lamps(400), a relay(200) and an external device. The receiving device controls the brightness of the N lamps. The transmitting device transmits the control command to the receiving device. The N lamps are a low voltage discharge lamp, a high voltage discharge lamp, an LED(Light Emitting Diode) or an EL(Electro-Luminescence). The relay is positioned between the transmitting device and the receiving device. The relay expands the communication range. The external device delivers control data or the control command operating time to the transmission device. The external device is computer, a PDA(Personal Digital Assistant) or an RFID(Radio Frequency Identification) reader.</p> |
