Abstract

L'invention concerne un circuit de commande d'une lampe électrique à décharge. Il comporte une impédance chutrice connectée en série avec la lampe à décharge et la source d'alimentation et un commutateur bidirectionnel commandé connecté en série avec un condensateur et une résistance entre l'une des bornes d'alimentation et une prise intermédiaire de l'impédance chutrice. Ce commutateur commandé est déclenché par un circuit de manière à produire plusieurs impulsions de tension élevée à chaque demi-période de la tension d'alimentation pendant la durée d'amorsage de la lampe. L'invention s'applique notamment aux lampes à vapeur de sodium à basse pression.
