1. An optical light beam projection device comprising:
a plurality of submatrices, each of the submatrices including a set of primary light sources, which emit light rays that propagate in a first direction; and
a primary optical system including a lens placed downstream of the set of primary light sources along the first direction, the lens having an input surface and an output surface, the input surface provided with a plurality of input dioptres, each of the plurality of input dioptres being placed in front of each of the submatrices and having a convex surface facing the submatrice, the output surface of the lens having a single output dioptre that is common to all of the submatrices, the plurality of input dioptres and the single output dioptre being made of an integral single piece of material,
wherein each of the submatrices is placed between each of the input dioptres and a focal point of the input dioptre and disposed on an optical axis of the input dioptre, the input dioptres are configured to form virtual images of the submatrices and the primary optical system is configured to form the virtual images in a plane, the virtual images being formed on a same side of the input dioptres as the submatrices.
