Abstract

The invention proposes a driver module {1) for driving LEDs, wherein the driver module (1) comprises: - a load path (4) comprising at least one LED string (6) with one or a plurality of LEDs (12, 13), - a current source (7) connected in series with the load path (4) for generating a current for the load path (4), and - a control module (8) for controlling the current for the load path (4) so that the shape of the current for the load path (4) matches the voltage (VA) applied to the load path (4).
