Control device, illumination device, and program for control device

A control device including a CPU is provided. The CPU outputs a plurality of pulses each having a duty set independently to LED. The CPU creates a schedule in which on-timing and off-timing of the plurality of pluses are designated such that the on-timing or the off-timing of two or more of the plurality of pulses is respectively not close to each other based on the set duty and a duty of the pulse. Further, the CPU sets, in a timer for counting time, time from a time point where the timer finishes counting the time already set to on-timing or off-timing of a pulse to be first turned on or off after the time point in accordance with the schedule. The CPU turns on or off the pulse in accordance with the schedule when the timer finishes counting the set time.
