Abstract

L'invention fournit une méthode pour fournir un motif lumineux pixélisé au moyen d'une matrice de sources lumineuses qui fournit une résolution de pixels supérieure à 0,1º, chaque source lumineuse étant configurée pour émettre un pixel lumineux. Ce procédé comprenant les étapes consistant à définir une surface de route ; et à projeter un motif lumineux pixélisé (5) sur la surface de la route. Dans le motif lumineux pixélisé (5), chaque pixel lumineux du motif lumineux est relié à tout autre pixel lumineux du motif lumineux par un trajet de pixels lumineux. En outre, la configuration de lumière pixélisée projetée s'étend d'une première distance (d1) inférieure à 10 m de la matrice des sources lumineuses à une seconde distance (d2) supérieure à 50 m de la matrice des sources lumineuses. L'invention prévoit également un dispositif d'éclairage automobile (1) comprenant une unité de commande (3) pour réaliser les étapes de cette méthode.Figure pour l'abrégé : figure 3bThe invention provides a method for providing a pixelated light pattern using an array of light sources which provides a pixel resolution greater than 0.1º, each light source being configured to emit a light pixel. This method comprising the steps of defining a road surface; and projecting a pixelated light pattern (5) on the road surface. In the pixelated light pattern (5), each light pixel of the light pattern is connected to any other light pixel of the light pattern by a light pixel path. Further, the projected pixelated light pattern extends from a first distance (d1) less than 10 m from the array of light sources to a second distance (d2) greater than 50 m from the array of light sources. The invention also provides an automobile lighting device (1) comprising a control unit (3) for carrying out the steps of this method.
