Abstract: A provided flash unit includes a light emitting part in the main unit of the flash unit and a distance sensor provided only in the light emitting part, achieving an accurate measurement of a distance from a subject.

Abstract: Provided is a strobe device that can properly illuminate a subject with flash light according to distances from a light-emitting unit to side walls as well as a ceiling. A strobe device 10 performs bounce photography in which flash light is emitted to a reflector so as to illuminate a subject with light reflected from the reflector including a ceiling H1 and side walls H2 and H3 that reflect the flash light. The strobe device further includes a distance-measuring unit capable of measuring distances from a light-emitting unit 13 to the subject, the ceiling H1, and at least one of the left side wall H2 and the right side wall H3.

Abstract: An object of the present invention is to provide a lighting device capable of properly performing a bounce motion and photography in the event of an unexpected motion. The lighting device of the present invention is a lighting device including a control unit that provides an instruction of an auto-bounce motion. When detecting an auto-bounce motion in S303, the control unit releases the brake of a motor for driving a light-emitting part and performs auto-bounce control in S304. When detecting that the bounce angle of the light-emitting part in the auto-bounce motion reaches a target position and the motor enters a stop period in S303, the control unit automatically switches to the application of an intermittently repeated regenerative brake to the motor. This can suppress a movement of the light-emitting part even in an accidental motion and perform a proper bounce motion with an easy manual operation.

Abstract: A strobe device of the present invention includes a reflector having an opening on the subject side, a cylindrical flashtube disposed in the reflector, and a first trigger electrode disposed on the outer peripheral surface of the flashtube. The first trigger electrode is disposed on the subject side of the outer peripheral surface of the flashtube. Thus, a flash of light emitted from the flashtube is reflected in a large range, from the bottom side to the opening side of the reflector, and a strobe device having a large range of light distribution can be achieved.
