Beschreibung
Zusammenfassung:	The invention relates to a lighting system comprising a load comprising a parallel configuration of a first LED load having a first forward voltage, and a first switch coupled in series with the first LED load; and a second LED load, having a second forward voltage being different than the first forward voltage; a switched mode power supply comprising a switching element; an inductor; a diode; a set of output pins for coupling to the load; and a capacitor coupled across the set of output pins; wherein the switched mode power supply is arranged to provide a voltage across the set of output pins, wherein the lighting system comprises a further inductor coupled between the one of the output pins and the load.
