Title (EN) REGULATOR FOR TWO LAMPS OF DIFFERENT STRENGTHS
(FR) VARIATEUR POUR DEUX LAMPES DE PUISSANCES DIFFERENTES
Abstract:
(EN) 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.
(FR) Un circuit double variateur de puissance, notamment circuit variateur de lumière, utilisé pour la commande de l'intensité lumineuse des lampes à incandescence telles que les lampes halogènes, caractérisé en ce qu'il se compose d'un circuit basse puissance et d'un circuit moyenne puissance dont la commande s'effectue par l'intermédiaire de deux curseurs reliés chacun à un potentiomètre dont l'un commande une lampe 220 volts environ 500 watts et l'autre commande une lampe basse tension, basse puissance par l'intermédiaire d'un transformateur 220 volts/ 6-12 ou 24 volts suivant le type de lampe d'une puissance environ 50 watts.
