What is proposed is: a circuit arrangement having at least two parallel-connected lighting chains, wherein a controller is connected in series with each lighting chain, wherein a current from a power supply operating as current source can be distributed between the lighting chains in such a way that at least that controller which is in the branch with the greatest voltage drop across the lighting chain has the greatest gain or can be operated in a saturated operating mode. In this case, it is advantageous that the lighting chains can each be operated stably with the current provided therefor. Also proposed are: a method for operating the lighting chains and a lighting module with at least one such circuit arrangement.
