Abstract

L'invention propose un dispositif de pilotage de l'alimentation électrique d'une source lumineuse, comprenant un circuit de pilotage configuré pour contrôler l'intensité du courant électrique de charge fourni par le dispositif en fonction de la valeur d'une tension électrique appliquée à une entrée dédiée du circuit de pilotage, ainsi qu'un circuit de contrôle du circuit de pilotage, permettant de générer un signal de contrôle pour son application à ladite entrée, le circuit de contrôle ne faisant intervenir qu'un seul composant actif.The invention proposes a device for controlling the electric power supply of a light source, comprising a driving circuit configured to control the intensity of the electric charging current supplied by the device as a function of the value of an applied electric voltage. to a dedicated input of the driving circuit, as well as a control circuit of the driving circuit, making it possible to generate a control signal for its application to said input, the control circuit only involving a single active component.
