Zusammenfassung:A Light Emitting Diode, LED, based current splitter for splitting an LED current between a plurality of LED channels, wherein said current splitter comprises at least two in series connected LED circuits, wherein each LED circuit comprises a first branch (B1.1, B2.1) comprising at least one LED, a second branch (B1.2, B2.2) connected in parallel over said first branch (B1.1, B2.1) and comprising at least one LED and a branch switch (W1, W3) connected in series with said at least one LED, wherein a forward voltage of said at least one LED in said second branch (B1.2, B2.2) is lower than a forward voltage of said at least one LED in said first branch (B1.1, B2.1) and a third branch (B1.3, B2.3) connected in parallel over said first and second branch (B1.2, B2.2) and comprising a shunt switch (W2, W4) for shunting said first branch (B1.1, B2.1) and said second branch (B1.2, B2.2).
