Abstract

La présente invention se rapporte à un procédé de pilotage d'un courant électrique au sein d'une source lumineuse à semi-conducteur , cette dernière comportant un substrat où au moins deux zones d'émission lumineuse sont distinctes, ledit procédé le procédé comprenant les étapes ci-après : - activer une première zone lumineuse, - régler la valeur moyenne de la grandeur électrique relative au courant électrique reçu par la source lumineuse en fonction d'une première consigne de sorte à obtenir une première valeur d'un premier flux lumineux correspondant au flux émis par ladite première zone lumineuse, activer au moins une deuxième zone lumineuse de la source lumineuse, - régler la valeur moyenne de la grandeur électrique relative au courant électrique reçu par la source lumineuse de sorte à obtenir une deuxième valeur d'un deuxième flux lumineux correspondant au flux émis par au moins ladite deuxième zone lumineuse.
