Abstract

L'invention fournit un dispositif d'éclairage automobile (10) comprenant un circuit de pilotage de lumière principal (1) avec une borne de sortie principale (5), un premier groupe (2) d'au moins une source de lumière à semi-conducteurs connecté en série à la borne de sortie principale, un second groupe (3) d'au moins une source de lumière connecté en série après le premier groupe d'au moins une source de lumière, et un circuit de pilotage de lumière secondaire (4) comprenant une borne de sortie secondaire étant connecté électriquement entre le premier groupe de sources de lumière et le second groupe de sources de lumière. Le circuit de pilotage de lumière secondaire étant configuré pour générer un courant supplémentaire, de sorte que le second groupe d'au moins une source lumineuse soit encore plus affecté par le courant supplémentaire. (Fig. 1))
