Claim 10:
11. An optical light beam projection device comprising:
a plurality of submatrices, each of the submatrices including a set of light emitting diodes, which emit light rays that propagate in a first direction; and
a primary optical system including a lens placed downstream of the set of light emitting diodes 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 light emitting diodes in each of the submatrices and having a convex surface facing the submatrice, the output surface of the lens having a plurality of output dioptres, each of the output dioptres being placed in front of each of the submatrices,
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.
