ABSTRACT:
A circuit arrangement for an LED array having two or more parallel-connected LED chains (LK1, LK2, LK3), in each of which at least one LED (2) is arranged and, when there are two or more LEDs (2), the latter are connected in series. In each case, the anode sides of the LED chains (LK1, LK2, LK3) can be coupled to the positive pole of a supply voltage (Uv) and the cathode sides can be coupled to the negative pole of the supply voltage (Uv). A regulating arrangement (RA1, RA2, RA3) for regulating an intended current distribution between the individual LED chains (LK1, LK2, LK3) is case connected in series with the respective LED chain (LK1, LK2, LK3).
