  In the transmitter 2 illustrated in FIG. 7, when the operation unit 21 receives a user operation, the transmission control unit 22 causes the transmission unit 23 to transmit a control signal through the channel selected by the channel changeover switch 24. Then, the control signal is received by the lighting device 6 for which the reception channel is selected by the channel changeover switch 61. In the lighting device 6 that has received the control signal, the microcomputer 34 controls the operation of the lighting circuit 35 based on the control signal. The lighting circuit 35 supplies an alternating current to the arc tube 13 based on the control of the microcomputer 34.

  For example, all of the three lighting devices 6 before the transmitter 2 transmits the control signal are turned off, and the control signal reception channel is used in the lighting device 6 covered with the shade 71 and the lighting device 6 covered with the shade 72.
