Abstract

Un dispositif de commande (20) est fourni, qui est utilisé avec une source de lumière (10) incluant une pluralité d'unités émettrices de lumière (12_1 à 12_N) connectées en série pour configurer une lampe pour véhicule (1). Le dispositif de commande (20) comporte une source de courant (30) qui est configurée pour délivrer un courant de commande à la source de lumière (10), et N circuits de dérivation (40_1 à 40_N) (40_1 à 40_N) qui sont respectivement prévus en parallèle avec N unités émettrices de lumière. Chacun des circuits de dérivation (40_1 à 40_N) comporte un transistor de dérivation (M1) qui est prévu en parallèle avec une unité émettrice de lumière correspondante, un condensateur de rétroaction (C1) qui est prévu entre la grille et le drain du transistor de dérivation (M1), et un circuit de commande de grille (60) qui est configuré pour délivrer une tension de commande entre la grille est la source du transistor de dérivation (M1), conformément à un signal de contrôle.
