<P>PROBLEM TO BE SOLVED: To provide a lighting control system capable of controlling a lighting apparatus and monitoring its operation state without comprising a relay control terminal apparatus with a communication function apart from the lighting apparatus. <P>SOLUTION: To a control unit 10, a plurality of transmission adapters 20 are bus-connected via a transmission line L1, and between the control unit 10 and the transmission adapters 20, signal transmission and reception are performed by low-speed power line carrier communication. To each transmission adapter 20, transmission lines L2 of a plurality of systems (for example, 4 systems) are connected, and plurality of pieces of lighting apparatus 1 are connected to each transmission line L2. Between the transmission adapter 20 and each lighting apparatus 1, communication is performed according to a DALI standard, and the communication between the control unit 10 and the lighting apparatus 1 is relayed by the transmission adapter 20. The control unit 10 transmits control data to the lighting apparatus 1 via the transmission adapter 20, and the lighting apparatus 1 controls a lighting state according to the received control data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
