Abstract:
(EN) A hybrid lens collimates light emitted by a light source via refraction and reflection. A folded optic element of the lens comprises an outer reflective surface, a lens output surface, and a hollow core comprising a sidewall having a curved profile, a core output boundary, and a core input opening through which the light emitted by the light source enters the hollow core. A reflector of the lens receives the light emitted by the light source, reflects a first portion of the light into the hollow core of the folded optic element, and directly transmits a second portion of the light into the hollow core without reflection by the reflector. In one example, the lens output surface has a diameter of 65 millimeters, the lens has a thickness (between the light source and the lens output surface) of about 13.5 millimeters and provides substantially collimated light with a beam divergence angle of 12 degrees or less.
(FR) Une lentille hybride collimate la lumière émise par une source de lumière par réfraction et réflexion. Un élément de système à trajet optique replié de la lentille comprend une surface réfléchissante externe, une surface de sortie de lentille, et un noyau creux comprenant une paroi latérale ayant un profil incurvé, une limite de sortie de noyau, et une ouverture d'entrée de noyau à travers laquelle la lumière émise par la source de lumière entre dans le noyau creux. Un réflecteur de la lentille reçoit la lumière émise par la source de lumière, réfléchit une première partie de la lumière dans le noyau creux de l'élément de système à trajet optique replié, et transmet directement une seconde partie de la lumière dans le noyau creux sans réflexion par le réflecteur. Dans un exemple, la surface de sortie de lentille a un diamètre de 65 millimètres, la lentille a une épaisseur (entre la source de lumière et la surface de sortie de lentille) d'environ 13,5 millimètres et fournit une lumière sensiblement collimatée avec un angle de divergence de faisceau inférieur ou égal à 12 degrés.
