Abstract
An illumination apparatus includes a main body, a movable unit, a first driving unit, a second driving unit, and a control unit. The movable unit is rotatable with respect to the main body and includes a light emitting unit and an optical member disposed in front of the light emitting unit to refract incident light. The first driving unit rotates the movable unit with respect to the main body. The second driving unit moves at least one of the light emitting unit and the optical member to change relative positions. Power is supplied to the second driving unit from a power source that supplies power to the first driving unit. The control unit controls a rotation operation performed using the first driving unit and a moving operation performed using the second driving unit so that the rotation operation is performed after the moving operation is performed.
