摘要:
A driving device includes a first switch element to switch between applying or not applying to a light-emitting element a voltage directed to setting the light-emitting element in an ON state, and a constant current control circuit to adjust a current flowing through the light-emitting element when the light-emitting element is in an ON state to a predetermined current value.
