摘要： A strobe device includes: a battery case configured to hold a plurality of batteries; a main capacitor charged by the batteries; a flash discharge tube to which a voltage is applied by the main capacitor; a voltage detecting unit configured to detect a voltage of each of the batteries, respectively; and a charging control unit configured to control charging of the main capacitor such that the main capacitor is charged with a first electric current that is suitable for lithium batteries in a case where a total voltage of the batteries detected by the voltage detecting unit is more than a prescribed first value, and control charging of the main capacitor such that the main capacitor is charged with a second electric current that is greater than the first electric current in a case where the total voltage is equal to or less than the first value.

摘要： An electronic flash device which is protected from thermally damaging a lamp holder (30) supporting a flash tube (40) even when the flash tube is lighted in a consecutive manner for a prolonged period of time. The lamp holder is made of ceramic material. The flash tube is supported by the lamp holder via a tube mounting member (44) which includes a wavy central part (44A) extending laterally along a back side of the lamp holder and a pair of annular parts (44B) fitted on either axial end of the flash tube such that the flash tube is resiliently urged against a bottom part of a concave mirror (42) received in the lamp holder.
