Light emitting element drive device and mobile apparatus

A light emitting element drive device comprising:

• a light emitting element;
• a drive unit for driving the light emitting element;
• first and second electricity storage elements capable of storing electric power;
• a battery power supply capable of supplying electric power to the drive unit and the electricity storage elements;
• and
• a control unit supplied by the battery power supply with electric power, for controlling the drive unit,
• wherein the drive unit is switchable between:
• a storing state in which the electricity storage elements and the light emitting element are parallel-connected to the battery power supply and in which electric power supplied from the battery power supply is stored in the electricity storage elements wherein electric power from the battery power supply is prevented from being supplied to the light emitting element;
• and
• a discharging state in which the first electricity storage element and the light emitting element are series-connected to the battery power supply and in which the electric power stored in the first electricity storage element is supplied to the light emitting element while the electric power stored in the second electricity storage element is supplied to the control unit.
