Abstract

a. Lampe fluorescente. b. Combinaison caractérisée par un réducteur de puissance dans le montage en série des deux contacts d'une extrémité de l'une des lampes, ce réducteur comprenant un moyen de commutation, qui, initialement lors de l'alimentation, présente une impédance faible pour permettre le passage du courant, puis commute à l'état d'impédance élevée, ce commutateur ayant un premier élément de commutation en série sur l'un des contacts d'une extrémité de la lampe, un second commutateur en série sur l'autre contact de cette extrémité de la lampe et un condensateur de limitation de courant de capacité prédéterminée, en parallèle aux bornes de l'un des éléments de commutation, de façon que lorsque le circuit est initialement alimenté, le moyen de commutation permet le préchauffage de l'électrode de la lampe reliant les contacts à une extrémité de cette lampe, puis lorsque le courant traverse le commutateur, celui-ci commute et fait passer le courant de la lampe à travers le condensateur de limitation de courant, en diminuant d'autant le courant traversant les lampes fonctionnant normalement.
