PURPOSE:To make the structure of lighting control apparatus simple and prevent effects of noise from outside by setting an address signal from a main apparatus and an address signal from a receiver of a wireless medium to be the same address. CONSTITUTION:A plurality of receivers 5 which receive wireless medium such as infrared-ray, electromagnetic wave, etc., are connected with each light modulating signal terminal device 3 through a transmitting line 6 and a light modulating signal sent from an operational part 7 of a hand switch, etc., is received by the receivers. In the terminal device 3, whether an address signal from a light modulation controlling main board 1 through a transmission interface (I/F) 11 is self address or not is determined by a transmitted data receiving address determining means 12. Meanwhile, an address signal from a receiver 5 through a receiver I/F 13 is determined by a receiver data receiving address determining means 14. An address switch 15 is connected with the means 12, 14 to set self address and the same address is set. Consequently, the structure of lighting control apparatus is made simple and effects of outside noise are prevented. |
