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.The invention relates to an optical device (1) for projecting a segmented light beam, in particular for a motor vehicle, characterized in that it comprises, upstream along an optical axis of the device, a matrix (2) of light sources (8) capable of emitting light rays, and downstream a primary optical system (4) provided with a first (5) and a second series of converging optics (6), the second series of converging optics (6) being downstream of the first series (5), the first series of optics (5) being configured to distribute the light rays coming from the light sources (8) on the optics (6) of the second series so that a optic (5) of the first series distributes the light rays which pass through it onto an optic (6) of the second series.
