Abstract

a. L'invention concerne un circuit destiné à signaler l'allumage correct d'une ou de plusieurs lampes électriques, qui fonctionne sans modification, même si l'on varie la consommation des lampes et la tension d'alimentation b. Une résistance 4 et une diode 5 sont intercalées dans chaque ligne alimentant une lampe, la résistance 4 ayant une valeur ohmique suffisamment grande pour que la tension à ses bornes soit egale à la tension de seuil de la diode 5 lorsque la lampe est allumée, mais assez petite pour que la tension à ses bornes soit sensiblement inférieure à la tension de seuil de la diode, si la lampe n'est pas allumée. c. Application au contrôle des lampes clignotantes de véhicules motorisés.
