Abstract: A lighting device is provided that includes a lighting controller that controls a light emitter that emits illumination light. The lighting controller includes a first filter that converts a first signal waveform that is defined by a first piecewise linear curve and whose intensity repeatedly increases and decreases into a signal waveform having a smooth rounded curve, and outputs the converted signal waveform as a first output waveform. The lighting controller causes the light emitter to repeatedly increase and decrease the intensity of the illumination light in accordance with the first output waveform.
