Abstract

L’invention propose un système d’éclairage pour un véhicule automobile comprenant au moins un module d’éclairage apte à projeter des fonctions d’éclairage à partir de données d’image, une unité de commande reliée par un canal de transmission de données à l’au moins un module d’éclairage et configurée pour générer une image de commande destinée audit module d’éclairage en fonction des caractéristiques optiques dudit module d’éclairage et d’une donnée de consigne. Le système est remarquable en ce que les données d’image sont compressés sur leur transit entre l’unité de commande et l’au moins un module d’éclairage. (Fig. 1)
