Abstract

L'invention présente un dispositif d'éclairage automobile (10) comprenant un régulateur de tension (1) avec une entrée de régulateur (11) et une sortie de tension régulée (13), un groupe d'éclairage contrôlé avec un pilote de lumière (4) et une pluralité de sources de lumière (2) et une unité d'élévation de tension (3) avec une entrée d'élévation de tension (31) et une sortie d'élévation de tension (32) configurée pour fournir une tension plus élevée que celle de la tension à l'entrée d'élévation de tension (31). Le groupe d'éclairage contrôlé est configuré pour être alimenté par la sortie de tension régulée (13) et le régulateur de tension (1) a une entrée auxiliaire (12) qui est connectée électriquement à la sortie d'élévation (32).Figure pour l'abrégé : figure 1
