Device and method for operating at least one lamp

摘要

A circuit arrangement for operating at least one electric lamp has a drive circuit (16) provided with at least one input-side connection for mains voltage and at least one output-side connection for at least one electric lamp. The drive circuit (16) has a control unit and a high-side switch choke (L2) and a switch (S1). The control unit is designed to operate the high-side switch in a discontinuous mode, in which the current (In) has gaps of duration (delta t).
