Abstract

L’invention concerne un système optique (60) comportant une lame dichroïque (61), agencée pour recevoir un faisceau lumineux incident (90) et configurée pour, d’une part laisser passer une partie du faisceau lumineux incident dont les longueurs d’onde sont comprises dans un premier intervalle compris dans le domaine de l’infrarouge, dite faisceau lumineux infrarouge (92), et d’autre part réfléchir une autre partie du faisceau lumineux incident dont les longueurs d’onde sont comprises dans un deuxième intervalle, distinct du premier intervalle, dite faisceau lumineux bleu (91). Le système optique comporte une première lentille (62) agencée pour recevoir le faisceau lumineux infrarouge et configurée pour le mettre en forme, un luminophore (64) agencé pour recevoir le faisceau lumineux bleu et configuré pour le convertir en lumière blanche, et une deuxième lentille (63) agencée pour recevoir la lumière blanche en vue de former un faisceau d’éclairage (93).
