A lighting control device switches an input voltage to generate an output voltage and supplies a driving current based on the output voltage to a lighting unit. A raw control signal is generated to specify a lighting period and an extinction period alternately, and a corrected control signal is generated by correcting the raw control signal based on the current through the lighting unit. A switching controller performs the switching of the input voltage during the lighting period specified by the corrected control signal and suspends the switching of the input voltage during the extinction period specified by the corrected control signal.
