PURPOSE: To previously display the number of times of available flashing when continuous flashing is carried out only by the energy accumulated in a main capacitor and also display the number of times of dimming in case of the generation of dimmed light in respect to a series controlling type automatically dimmed speed light.
CONSTITUTION: A detecting circuit 5 detects the number of times of available flashing from the charging voltage of a main capacitor CM and outputs number of pulses corresponding to the number of times to a terminal (a). A shift register SR counts up the number of outputted pulses of the terminal (a) and turns on some of light emitting diodes D1WDn in accordance with the counted value and the number of emitted diodes indicates the number of times of available flashing. The shift register SR is reset by release operation, reads a diming stop controlling pulse inputted to an input terminal D from a comparator CP in every flashing and turns on light emitting diode one by one in every input of a pulse. The number of emitted diodes indicates the number of times of available flashing.
