Patent ID: 7606480

Claim:
A photographic illuminating device, comprising: a high voltage generating circuit that includes an input side and an output side, raises a voltage provided at the input side by a battery, and outputs a high voltage from the output side; a discharge-controlled illumination unit that is electrically connected to the output side of the high voltage generating circuit, is driven with the high voltage output from the high voltage generating circuit and emits illuminating light in response to a light emission instruction; a current-controlled illumination unit that is electrically connected to the output side of the high voltage generating circuit, is applied with the high voltage output from the high voltage generating circuit and emits illuminating light in response to a light emission instruction; a mode selecting unit configured to be electrically connected to the discharge-controlled illumination unit and the current-controlled illumination unit and to select one of a first light emission mode in which the illuminating light emitted by the discharge-controlled illumination unit is used as illuminating light for photographing, and a second light emission mode in which the illuminating light emitted by the current-controlled illumination unit is used as illuminating light for photographing, the illuminating light for photographing controlling a brightness of a subject to be photographed; and a current control circuit that supplies a current needed for light emission at the current-controlled illumination unit by using the high voltage output from the high voltage generating circuit to the current-controlled illumination unit when the second light emission mode is selected by the mode selecting unit, wherein the high voltage generating circuit is commonly used by the discharge-controlled illumination unit and the current-controlled illumination unit.
