Abstract
Lampe éclair électronique comportant un commutateur de marche-arrêt et une lampe à effluves se présentant sous la forme d'une lampe de contrôle de charge. Le commutateur de marche-arrêt constitue un relais avec un électro-aimant 4, l'électro-aimant étant branché en aval de la lampe à effluves 10 et celle-ci commandant l'excitation de l'électro-aimant, et la lampe à effluves étant raccordée à un diviseur de tension dont une branche comporte une résistance invariable 13 et dont la seconde branche présente pendant le processus de charge du condensateur à haute tension 9 une résistance différente de celle qu'elle présente à la fin du processus de charge. Application notamment à un appareil photographique.
