<p>A dual regulator circuit, particularly a light dimmer circuit, for controlling the brightness of filament lamps such as halogen lamps. It is characterized in that it consists of a low-power circuit and a medium-power circuit controlled via two cursors connected to a potentiometer, one of which controls a 220 volt, approximately 500 watt lamp while the other controls a low-voltage, low-power lamp via a 220 volt/ 6-12 or 24 volt transformer according to the kind of lamp, with a power of approximately 50 watts.</p> |
