Abstract

L’invention concerne un système d’éclairage (1) pour véhicule automobile, comportant : une source lumineuse pixélisée (2) présentant une pluralité de sources de lumière élémentaires (21) activables sélectivement, l’activation de chaque source de lumière élémentaire étant exclusivement contrôlée par un interrupteur (22) dédié à cette source de lumière élémentaire; un convertisseur de puissance (3) agencé pour fournir une puissance électrique (Ps) à la source lumineuse pixélisée ; un contrôleur (4) agencé pour contrôler la tension électrique (Vs) fournie par le convertisseur de puissance et pour contrôler les interrupteurs contrôlant l’activation des sources de lumière élémentaires ; le système d’éclairage comportant un capteur de courant électrique (5) agencé pour mesurer le courant électrique (Is) fourni par le convertisseur de puissance à la source lumineuse pixélisée et pour transmettre une information relative à ce courant mesuré au contrôleur. Figure pour l’abrégé : Fig. 1
