Abstract:
A power supply control device includes a photoelectric conversion unit to convert light energy to electricity, and a power supply control signal output unit driven by power converted by the photoelectric conversion unit and configured to detect a change in lighting intensity at an installation environment of the power control device based on an output voltage of the photoelectric conversion unit to output a power control signal which causes power of an external device to start up or shut down to the external device.
