Abstract:
An illumination apparatus includes a light source portion including a light emitter and a reflector configured to reflect light from the light emitter, a mover configured to move at least one of the light emitter and the reflector so that a relative distance between the light emitter and the reflector varies in order to change a light distribution angle of the light source portion, and a controller configured to control a position of at least one of the light emitter and the reflector via the mover based on a light emission amount of the light emitter.
