Abstract

Lampe à décharge à basse pression sans électrodes munie d'une ampoule 1 contenant une vapeur métallique et un gaz rare et d'un noyau 4 en matériau magnétique; lors du fonctionnement avec un enroulement 5 appliqué autour de ce noyau et une unité d'alimentation à haute fréquence y connectée, un champ électrique est engendré dans l'ampoule qui est en outre munie d'une couche conductrice transparente interne 11, et aussi d'une couche conductrice externe 12 qui, lors du fonctionnement de la lampe, est connectée à l'un des conducteurs du réseau, ladite couche conductrice externe 12 constituant, de concert avec la couche conductrice interne 11, une capacité.
