Abstract

L'invention concerne un dispositif optique (1) de projection de faisceau lumineux segmenté, notamment pour véhicule automobile, caractérisé en ce qu'il comprend en amont selon un axe optique du dispositif, une matrice (2) de sources (8) de lumière aptes à émettre des rayons lumineux, et en aval un système optique primaire (4) muni d'une première (5) et d'une deuxième série d'optiques (6) convergentes, la deuxième série d'optiques (6) convergentes étant en aval de la première série (5), la première série d'optiques (5) étant configurée pour répartir les rayons lumineux provenant des sources lumineuses (8) sur les optiques (6) de la deuxième série de manière à ce qu'une optique (5) de la première série distribue les rayons lumineux qui la traversent sur une optique (6) de la deuxième série.
