Abstract

La présente invention concerne un module lumineux comportant une source lumineuse à semi-conducteur (1,2) et un circuit de pilotage (3) de l'alimentation en courant de la source lumineuse. Le circuit de pilotage est connecté à la source lumineuse par un réseau de connexion (6) comprenant au moins un pontage par un fil métallique (61). Selon l'invention, le circuit de pilotage est agencé pour déterminer une valeur du courant électrique parcourant ladite source lumineuse par une mesure de la tension aux bornes dudit fil métallique (61). On supprime ainsi la résistance de shunt qui est habituellement utilisée pour la détermination du courant parcourant la source lumineuse.
