A Circuit arrangement (1) for an LED module (53) comprising a plurality of serially connected LEDs (11-25), comprises a first current source (35) and a second current source (36). The first current source (35) is serially connected to all the LEDs (11 - 25) of the LED module (53). The second current source (36) is serially connected to a first sub-set (33) of LEDs (11 - 24) of the LED module (53). The LEDs (11 - 24) of the first sub-set (33) are serially connected. The first sub-set (33) comprises at least one LED (25) less than the LED module (53). |
