LED current pulse limiter arrangement

摘要

An arrangement for supplying a constant current to at least one LED includes a current source ( 2; 2 a , 2 b) with an output capacitor ( 3 ) connected across the terminals of the current source. An output inductor ( 4 ) is associated with the output capacitor ( 3 ) whereby the current supplied flows through the inductor ( 4 ). A smoothing resistor ( 5 ) is preferably connected in parallel to the output inductor ( 4 ).
