Abstract (en)
The invention relates to a circuit arrangement for operating at least two gas-discharge lamps (LA1, LA2), in particular HID lamps with power consumption differing from one another, wherein each lamp (LA1, LA2) is situated in a parallel branch (PZ1, PZ2) and is connected in series with an inductor (L1, L2). In order to guarantee that differing power consumptions of the lamps (LA1, LA2) have as little interfering effect on one another as possible, it is proposed that at least the inductors (L1, L2) are produced and/or selected in such a way that their inductance values are the same, within predetermined tolerance limits.
