Abstract

L'invention concerne un dispositif lumineux comprenant une première rangée de sources lumineuses pour générer des premiers faisceaux unitaires et une deuxième rangée de source lumineuse pour générer des deuxièmes faisceaux unitaires. Les premiers faisceaux unitaires ont un profil en pente. On associe les premiers faisceaux unitaires et les deuxièmes faisceaux unitaires de sorte à construire un faisceau résultant doté d'une pente et d'une portion s'étendant latéralement à partir de la pente.
