Kind Code:
B2
Abstract:
A lighting device capable of suppressing an excessive temperature rise of a light emission section even when a fan is incapable of normal rotation. The light emission section emits light for illuminating an object. The fan cools the light emission section. A motor driving section drives the fan for rotation. A strobe microcomputer determines whether or not the motor driving section is abnormal, and controls a light emission interval of the light emission section in continuous light emission, based a result of the determination.
