发明名称 Strobe device and image pickup device
摘要 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.

主权项 1. A strobe device comprising: a reflector having an opening on a subject side; a flashtube disposed in the reflector; and a first trigger electrode disposed on an outer peripheral surface of the flashtube, the first trigger electrode is disposed on the subject side of the outer peripheral surface of the flashtube, and the first trigger electrode includes a transparent conductive film, wherein the flashtube emits light at a large quantity and at a small quantity smaller than the large quantity, and when the flashtube emits light at the small quantity, the trigger circuit extends a time period over which a trigger signal is applied to the first trigger electrode or the trigger circuit increases a voltage of the trigger signal.
