Abstract: An illumination control system includes a manipulation detector and an electric power controller. The electric power controller stops supply of electric power to a plurality of lighting apparatuses when an OFF manipulation is detected. The electric power controller starts the supply of the electric power to the lighting apparatuses when an ON manipulation is detected after detection of the OFF manipulation and before a first timing, or when the ON manipulation is detected at or after a second timing. The first timing is a timing at which a threshold time which is predetermined has elapsed since the detection of the OFF manipulation. The second timing is a timing at which a predetermined forced interruption time has elapsed since the first timing.

Abstract: A power supply device includes converters, a command circuit, and a setter. The converters correspond to loads. The command circuit controls the converters. The setter sets a magnitude of an output of at least one target converter of the converters in accordance with an output characteristic representing a relationship between an input voltage of the at least one target converter and an output limit value which is an upper limit value of the output from the at least one target converter. The output characteristic is a characteristic that the output limit value decreases as the input voltage lowers when the input voltage is lower than a threshold. The setter varies the threshold of the output characteristic in accordance with an operation status of the converters and sets the magnitude of the output from the at least one target converter in accordance with the output characteristic whose threshold has been varied.

Abstract: The signal transmitting device includes: a transmitter-side input for receiving a first DC voltage; a transmitter-side output for outputting a second DC voltage; and a voltage conversion circuit configured to convert the first DC voltage into the second DC voltage. Further, the signal transmitting device includes a control circuit configured to control the voltage conversion circuit so that the second DC voltage has a voltage value (selected from a first voltage value and a second voltage value) which changes according to transmission data in a predetermined transmission period.
