A SYSTEM FOR FEEDING LIGHT SOURCES SUBJECT TO DIMMING AND CORRESPONDING METHOD

摘要

A system for feeding a light source (L) such as a halogen lamp (L) via a bridge arrangement (10) having an input filter (14) for connection to a dimmer (12). The system includes a resistor (Rl) for coupling to the input filter (14) in order to form a snubber circuit in order to prevent oscillations of the input filter (14) and the bridge arrangement (10). The system including a switch (Sl) sensitive (16, SB) to the load on the bridge arrangement (10) to selectively couple the resistor (Rl) to the input filter (14) when the load on the bridge arrangement (10) is below a given threshold.
