Abstract

L'invention concerne un dispositif lumineux (1), notamment pour véhicule automobile, comprenant au moins une source de lumière (2) apte à émettre des rayons lumineux pour former un faisceau lumineux, et en outre :
- une première surface de transmission (3) munie de motifs dispersifs,
- des moyens de répartition configurés pour distribuer le faisceau lumineux sur la première surface de transmission (3), et
- une deuxième surface de transmission (10) agencée de manière à transmettre les rayons lumineux provenant de la première surface de transmission (3), la deuxième surface de transmission (10) étant également munie de motifs dispersifs.
