Abstract

This strobe device is provided with: a flash discharge tube that has an anode disposed on one end side and a cathode disposed on the other end side and provided with a metal sintered body on a leading end part; an electrically conductive reflector that constitutes a trigger outside electrode that accommodates part of the flash discharge tube; and a trigger coil having a primary winding and a secondary winding wound around a hollow core. A part of the flash discharge tube cathode that does not include the metal sintered body is inserted into the trigger coil core, and the reflector is provided with a base part in contact with an outer peripheral surface of the flash discharge tube so as to cover at least the part between the anode and cathode and the metal sintered body and is also connected to the secondary winding of the trigger coil. Thus, a strobe device with little variation in intensity can be achieved.

Description

Technical field [0001] The present invention relates to, for example, a strobe device for photographing. Background technique [0002] At present, the following strobe device is known. The strobe device is provided with: a flash discharge tube having an anode arranged on one end side and a cathode arranged on the other end side and provided with a metal sintered body at the tip; a reflector, It houses a part of the flash discharge tube inside; the trigger coil has a primary winding and a secondary winding around the outer circumference of a cylindrical iron core. [0003] In the above stroboscopic device, a conductive thin-film transparent electrode is provided on the surface of the flash discharge tube, and the secondary winding of the trigger coil is connected to the thin-film transparent electrode of the flash discharge tube. As a result, the thin-film transparent electrode functions as a trigger external electrode to light up the flash tube. [0004] In addition, in the above-m...
