Abstract
(EN)
A lens includes an exit surface for allowing transmission light to be emitted and a light receiving surface being at least part of the back surface of the exit surface and receiving light becoming the source of the transmission light. The lens includes at least one of the exit surface satisfying the following condition (1) and the light receiving surface satisfying the following condition (2): (1) The edge of the exit surface is ring-like, and one arbitrary point inside the ring is chosen as a reference point. The exit surface includes a non-spherical surface formed by an aggregate of a plurality of points spaced apart from the reference point by different arbitrary distances (however, the ring-like edge of the exit surface includes at least three inflection points). (2) The edge of the light receiving surface is ring-like, and one arbitrary point inside the ring is chosen as a reference point. The light receiving surface includes a non-spherical surface formed by an aggregate of a plurality of points spaced apart from the reference point by different arbitrary distances (however, the ring-like edge of the light receiving surface includes at least three inflection points).

L'invention concerne une lentille comprenant une surface de sortie permettant d'émettre une lumière de transmission, et une surface de réception de lumière qui fait au moins partie de la surface arrière de la surface de sortie et recevant de la lumière, qui devient la source de la lumière de transmission. La lentille comprend la surface de sortie satisfaisant la condition suivante (1) et/ou la surface de réception de lumière satisfaisant la condition suivante (2) : (1) le bord de la surface de sortie est en forme d'anneau et un point arbitraire à l'intérieur de l'anneau est choisi comme point de référence. La surface de sortie comprend une surface non sphérique formée d'un agrégat d'une pluralité de points espacés du point de référence selon différentes distances arbitraires (cependant, le bord en forme d'anneau de la surface de sortie comprend au moins trois points d'inflexion). (2) le bord de la surface de réception de lumière est en forme d'anneau et un point arbitraire à l'intérieur de l'anneau est choisi comme point de référence. La surface de réception de lumière comprend une surface non sphérique formée d'un agrégat d'une pluralité de points espacés du point de référence selon différentes distances arbitraires (cependant, le bord en forme d'anneau de la surface de réception de lumière comprend au moins trois points d'inflexion).
