Abstract

L'invention concerne une source lumineuse (300) comprenant : une puce DEL (110) émettant une lumière possédant une première longueur d'onde centrale ; une couche dichroïque (120) sur la puce DEL (110), la couche dichroïque (120) transmettant une lumière possédant la première longueur d'onde centrale et réfléchissant une lumière possédant une seconde longueur d'onde centrale ; une couche de phosphore (130), sur la couche dichroïque (130), convertissant la lumière possédant la première longueur d'onde centrale en une lumière possédant la seconde longueur d'onde centrale ; un filtre angulaire (140), sur la couche de phosphore (130), transmettant une lumière dans un cône de transmission et réfléchissant la lumière hors du cône de transmission ; et un polariseur réfléchissant (150), sur le filtre angulaire (140), transmettant une lumière possédant une première polarisation et réfléchissant une lumière possédant une seconde polarisation orthogonale à la première polarisation.
