Current driver and driving method

A LED circuit comprises a current drive circuit for driving a current through the parallel combination of a LED arrangement and an output capacitor. An override arrangement overrides the current level setting to a default current level during start-up, and the override arrangement is disabled when a current flow is sensed by a sensor. The current setting of the driver is ignored until a threshold current is sensed through the LED arrangement. The delay associated with initial start-up charging of the output capacitor is thereby avoided.
