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. In the flash unit according to the present invention, the light emitting part () includes a light receiving element () that measures reflected light when light is emitted in advance from the light emitting part () to a subject (T) and reflected light when light is emitted in advance from the light emitting part () to a reflector (X) for bounce photography, the flash unit determines and controls a proper tilt angle (&#x3b8;) of the light emitting part () relative to a main unit () based on a distance (La) from the subject (T) and a distance (Lb) from the reflector (X), the distances being measured based on the detection by the light receiving element (), and directivity for the detection by the light receiving element () is tilted toward the main unit () with respect to a horizontal direction.

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 S, the control unit releases the brake of a motor for driving a light-emitting part and performs auto-bounce control in S. 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.

Lighting device and imaging device

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.
