  • Publication number: 20220264728
    Abstract: A lighting device includes: a light emitting unit that emits illumination light; and a control unit that controls an intensity of the illumination light. The control unit controls the intensity of the illumination light in each of a period of no change during which the control unit keeps the intensity of the illumination light constant and a period of change during which the control unit changes the intensity of the illumination light as time passes. The period of no change is longer than the period of change.
