Abstract:
An LED module (10) for operating at least one LED (18) comprising an input (E1, E2) adapted for coupling to a DC voltage source (UE); an output (A1, A2) adapted for coupling to the at least one LED (18); a filter device (14); and a DC-DC converter (16); wherein the filter device (14) and the DC-DC converter (16) are coupled in series between the input (E1, E2) and the output (A1, A2), and wherein the output (DCA1, DCA2) of the DC-DC converter (16) is coupled to the output (A1, A2) of the LED module (10); wherein the LED module further comprises an electronic switch (Q1), which is configured to couple the DC-DC converter (16) to the input (E1, E2) of the LED module (10) and to decouple it therefrom.
