Abstract

Dispositif de commande pour lampes à décharge comprenant un dispositif à induction. L'invention est caractérisée en ce que le dispositif à induction est une self à prises intermédiaires dont une est reliée à un condensateur et un dispositif électronique normalement bloqué, et en ce qu'à une prise intermédiaire d'un diviseur de la tension de la lampe est relié un condensateur et un circuit de commande pour le dispositif électronique comprenant un seuil d'amorçage pour une tension aux bornes de ce dernier condensateur au-dessus de celle représentant la tension image du régime de la lampe. Applicable aux lampes à vapeur de sodium à basse pression.
