First Claim
Patent Images

1. flasher, it utilizes when photographic images the electrical power of main capacitance (71) charging is sent fill-in light, and this flasher comprises:

  • Progressively dropping equipment (81) is used to reduce the charging voltage of main capacitance (71) and voltage is provided to other place as electrical power;

    Switch (82), it carries out handover operation so that this main capacitance (71) is switched to this progressively dropping equipment (81) from the charging circuit (72) of this main capacitance, thereby this main capacitance (71) is connected to this progressively dropping equipment (81);

    AndControl device (2) is used to make this switch (82) to carry out required handover operation.
