<p>A circuit (236, 300, 400, 536) is provided for an apparatus (200, 500) configured to convert an AC signal to a DC signal for driving at least one light source (240, 540). The circuit includes a damping element (350, 450) configured to damp a current in the apparatus during time periods when the current exceeds a threshold, and a bypass path (340, 440) for bypassing the damping element during time periods when the current does not exceed the threshold.</p> |
