Abstract
A vehicle luminous module intended to generate a light beam along an optical axis includes primary light guides each including an entrance dioptric interface and an exit, and a light source arranged facing an entrance dioptric interface. A projecting assembly includes a focal region and an exit member, the projecting assembly being arranged so that the light rays passing through said focal region and reaching the exit member are imaged in a projection field downstream of said projecting assembly. The exits of the guides are arranged level with the focal region. The luminous module includes at least one secondary light guide distinct from the primary light guides, and arranged so as to deviate light rays generated by the light source so that they do not reach the exit member, and/or so as to spread said light rays in said projection field.
