Patent

CA 2199199

A circuit arrangement (4) for the operation of electrical lamps, with a printed circuit board (5), on which 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), has an equipotential surface (6) for reducing the radio interference caused by these potential changes. For this purpose, equipotential surface (6) with resting potential relative to the rapid potential changes is connected onto printed circuit board (5). In particular, the equipotential surface is produced by a copper layer (6) on the upper side of printed circuit board (5). The advantage is a simple-to-produce arrangement that can be automated for reducing radio interference.
