Abstract (en)
Resistive circuit for an electronic dimmer device (2) equipped with a power semiconductor, which circuit (1) contains a resistive load (3) connected to the dimmer device (2) as an auxiliary load or built in in the dimmer device, characterized in that it contains detection means (6) to detect the moment when the power semiconductor of the dimmer device (2) is connected and switching means (4 and 5) to switch on the resistive load (3) for a restricted length of time (T) when said detection means (6) detect that the power semiconductor is connected. <IMAGE>
