Abstract

L'invention concerne un module (20) électroluminescent, comprenant au moins deux sources lumineuses (1), qui sont placées sur un support commun (7). Une des sources lumineuses (1) comprend au moins deux puces à diodes électroluminescentes (2). Chaque source lumineuse (1) du module est un corps optique (3) d'un élément optique (5), et les corps optiques (3) sont destinés à conduire un rayonnement électromagnétique vers une face de sortie lumineuse (4) de l'élément optique (5). De plus, un appareil de projection optique est pourvu du module électroluminescent de l'invention.
