<p>PROBLEM TO BE SOLVED: To provide a lighting system, capable of easily confirming the connection state of a communication line. SOLUTION: Plural luminaires are each provided with a communication part 5 equipped with first and second communication ports 5a and 5b; a central processing part 6 generating a lighting control signal for controlling the lighting state of a lamp; and a load control part 7 for lighting the lamp in the lighting state according to the lighting control signal; and the respective communication ports 5a and 5b are connected to different luminaires via communication lines 10. The central processing part 6 generates the lighting control signal for lighting the lamp in a prescribed lighting state and outputs the lighting control signal from the respective communication ports 5a and 5b as control data, when a test signal is inputted from the outside. When the central processing part 6 receives the control data from either of the communication ports 5a and 5b, it controls the lighting state of the lamp according to the control data, and outputs the received control data from the other of the communication ports 5a and 5b.</p> |
