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 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.
