Abstract (en)
[origin: WO2008098613A1] The present invention relates to an LED module (10) for operating at least one LED (18) with an input (E1, E2) for coupling to a DC voltage source (U<SUB>E</SUB>); an output (A1, A2) for coupling to the at least one LED (18); a filter apparatus (14); and a DC-DC converter (16); wherein the filter apparatus (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 it furthermore comprises an electronic switch (Q1), which is designed to couple the DC-DC converter (16) to the input (E1, E2) of the LED module (10) and to decouple it therefrom. The invention moreover relates to a corresponding method for operating at least one LED using an LED module.
