Abstract
L'invention fournit un dispositif lumineux automobile (10) comprenant une source lumineuse à semi-conducteurs (3) à commander, un contrôleur (4) avec une entrée de capteur de température (42) et un premier circuit. Le premier circuit comprend une sortie de circuit (5) reliée à l'entrée du capteur de température (42). Le premier circuit comprend en outre un dispositif de limitation de la tension et un capteur de température (7), de sorte que la sortie du circuit est configurée pour fournir dans la sortie du circuit (5) une tension qui est toujours inférieure à une valeur de tension de seuil définie par le dispositif de limitation de la tension.Figure pour l'abrégé : figure 1
