<P>PROBLEM TO BE SOLVED: To provide a control device for outdoor lighting which can improve energy-saving effect by reducing power consumption amount to consume electric power from a commercial power supply including standby power. <P>SOLUTION: The control device for outdoor lighting 4 has a control circuit 15 which outputs a control signal for controlling switching on and off a lighting load 2a to be connected to a power supply source 6 in series and a switching part 11 which is in insulated state from the control circuit 15 and performs switching of lighting on and off the lighting load 2a by supplying the control signal to the lighting load 2a. Then, when a lighting load switch-on information is detected by a detection part 17 for detecting the starting information to control switching on and off the lighting load 2a, the control circuit 15 makes charge the power extracted from the power supply source to a charging section 16, and when the lighting load switch-on information is not detected, the control circuit 15 controls the power supply circuit part 13 so as to charge the power from a photoelectric generating part 14 to the charging section 16. <P>COPYRIGHT: (C)2009,JPO&INPIT |
