Abstract (en)
[origin: US2020041093A1] A luminous motor-vehicle module, comprising an array of light sources and a bifocal imaging device that is designed to project an image of each light source, wherein the luminous module comprises at least one primary optical element, which at its exit does not modify in a vertical direction V the angle of the incident rays, and which allows secondary sources to be formed the lateral dimension of which is larger than a lateral dimension of the light sources and the angular aperture of the emitted secondary light beams of which is smaller than an angular aperture of the light beams emitted by the light sources.
Abstract (fr)
L'invention concerne un module lumineux (10) de véhicule automobile, comprenant :- un réseau (12) de sources lumineuses (14) ;- un dispositif (30) bifocal d'imagerie qui est conçu pour projeter une image de chaque source lumineuse (14);caractérisé en ce que le module lumineux (10) comporte au moins un élément optique primaire (40), qui ne modifie pas en sortie selon une direction verticale V l'angle des rayons incidents, et qui permet de former des sources secondaires (62) dont la dimension latérale est plus grande qu'une dimension latérale des sources lumineuses (14) et dont l'ouverture angulaire (β) des faisceaux secondaires de lumière (18) émis est inférieure à une ouverture angulaire (α) des faisceaux de lumière (16) émis par les dites sources lumineuses (14).
