Abstract
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.
