Abstract

L'invention concerne un dispositif lumineux configuré pour émettre un faisceau lumineux segmenté (3), notamment pour véhicule automobile, comprenant un premier module optique (1) comportant une première série de sources de lumière (1a, 1b, 1c, 1 d, 1e) aptes à émettre des rayons lumineux, chaque source de lumière étant sélectivement adressable et configurée pour générer un segment (5) du faisceau lumineux de manière à former une première rangée (13) de segments (5), la première rangée (13) de segments comportant un premier et un deuxième segment latéral (14, 15) à chaque extrémité de la première rangée (13), caractérisé en ce que le dispositif comprend en outre un deuxième module optique comportant une première source de lumière spécifique configurée pour générer un premier segment latéral supplémentaire (19) élargi par rapport aux autres segments (5), le premier segment latéral supplémentaire (19) étant apte à recouvrir au moins en partie le premier segment latéral (14) de la première rangée (13) de manière à former un premier bord du faisceau lumineux (3), et qui est destiné à éclairer un côté de la route.
