  The illumination load 40 of the illumination device 4 is a halogen lamp that operates with AC power, and the illumination load 50 of the illumination device 5 is an LED lamp that operates with DC power.

  The mobile dimming unit 6 includes a receiving means (hereinafter referred to as a power line carrier communication device as an example of the receiving means) 60 and a dimming power supply circuit 61.

  The power line carrier communication device 60 is connected to the AC power line 1 so as to receive a DMX control signal superimposed on the AC power line 1 for controlling the illumination load 40 of the lighting device 4.

  The dimming power supply circuit 61 is connected to the AC power line 1 and is connected to the power line carrier communication device 60 so as to receive the DMX control signal, and the illumination load 40 of AC power supplied from the AC power line 1 by the DMX control signal. The phase control of the power to is performed. The AC power dimming power supply circuit 61 is not limited to AC power phase control but may be AC power pulse width modulation control.

  The dimming power supply circuit 61 is connected to a lighting load 40 of AC operation. The dimming control of the lighting load 40 is performed by supplying phase-controlled power to the lighting load 40. Can be done.

  The mobile dimming unit 7 includes a receiving means (hereinafter referred to as a power line carrier communication device as an example of the receiving means) 70, a DC conversion circuit 71, and a dimming power supply circuit 72.

  The power line carrier communication device 70 is connected to the AC power line 1 so as to receive a DMX control signal superimposed on the AC power line 1 for controlling the illumination load 50 of the lighting device 5.

  The DC conversion circuit 71 rectifies AC power supplied from the AC power line 1, smoothes the rectified DC, and supplies it as DC power. The DC power line 1 and the dimming power supply circuit 72 are connected so as to supply this DC power to the dimming power supply circuit 72.

  The dimming power supply circuit 72 performs on / off control (for example, PWN control) at a speed that cannot be visually perceived without changing the DC voltage of the DC power supplied from the output of the DC conversion circuit 71 to the illumination load 50. Yes, it is connected to the power line carrier communication device 70 and the DC conversion circuit 71.

A corresponding specific signal is included, and based on this specific signal, the power line carrier communication device 60 and the power line carrier communication device 70 to which the corresponding number and address are assigned can receive the DMX control signal.

  The DMX control signal superimposed on the AC power line 1 is received by the power line carrier communication device 60 or the power line carrier communication device 70.

  On the mobile dimming unit 6 side, the dimming power supply circuit 61 performs power control (for example, phase control) on the basis of the DMX control signal received based on the specific signal described above and By supplying the phase-controlled electric power, dimming control is performed on the illumination load 40 of AC operation.

  On the mobile dimming unit 7 side, the DC conversion circuit 71 converts AC power supplied from the AC power line 1 into DC power, and based on the DMX control signal received by the dimming power supply circuit 72 based on the specific signal described above. Thus, the lighting load 50 of DC operation is dimmed and controlled by supplying DC power to the lighting load 50 with on / off control.

  That is, the lighting system A can control the lighting load 40 that operates with AC power and the lighting load 50 that operates with DC power.

  In addition, when the lighting loads 40 and 50 are controlled, the lighting loads 40 and 50 can be controlled without performing an operation or control for manually switching the wiring.

  In addition, since the lighting loads 40 and 50 are not switched and controlled, the lighting loads 40 and 50 can be controlled simultaneously.

  Furthermore, the lighting system A is constructed with a relatively simple configuration in which the DMX dimming control device 3 is connected to the AC power line 1 via the power line carrier communication device 2 and the mobile dimming units 6 and 7 are connected. Therefore, the lighting system A can be expected to be reduced in size and manufacturing cost.

  Therefore, it is possible to easily control the different illumination loads 40 and 50 and to provide the illumination system A that can easily perform the installation work and the transport work at low cost.
