1. An electrical circuit arrangement (4) with a printed circuit board (5;

  • 22) for the operation of electrical lamps, on which printed circuit board (5), electrical components (14) and conductor strips (7;

    19;

         20) are arranged, whereby potential changes that are rapid over time occur on printed circuit board (5;

         22), as well as with an equipotential surface (6;

         23) for reducing the radio interference caused by these potential changes, is hereby characterized in that equipotential surface (6;

         23) is connected with a resting potential (7;

         29) relative to the rapid potential changes on printed circuit board (5;

         22), the equipotential surface (6;

         23) is arranged at least in the vicinity of the upper side or lower side of printed circuit board (5;

         22), the equipotential surface (6) is joined with a ground conductor strip (7) arranged on the under side of printed circuit board (5) by means of a solder or wire bridge (8) via a hole (9) in printed circuit board (5).
