  • Publication number: 20170198884
    Abstract: This light flux control member comprises a first (second) light flux control member. The first light flux control member comprises an entry region including a Fresnel lens portion and an entry surface; an exit surface; and a reflective surface. The reflective surface is a rotationally symmetric surface with the central axis of the first light flux control member as the rotation axis. The reflective surface is formed such that the generatrix of the reflective surface is a concave curve relative to the entry surface and the outer peripheral portion of the reflective surface is distanced farther from an orthogonal plane compared to the inner peripheral portion thereof in a direction that follows an optical axis, which is the center of the total light flux of at least one light-emitting element, said orthogonal plane passing through an arbitrary point on the entry surface and being orthogonal to the optical axis.
