Patent number: 6873122Abstract: An apparatus for operating a plurality of discharge lamps is to be designed so as to be more cost-effective. A first current control device, in particular a heat-sensitive resistor having a positive temperature coefficient, is connected in parallel with a first contact device for electrically connecting a first discharge lamp. Furthermore, a second contact device for electrically connecting a second discharge lamp is connected in parallel with a second current control device, the first and second contact devices being connected in series.
