請求の範囲第１項記載の集光レンズ。[Claims for Utility Model Registration] (1) An integrated condensing lens that condenses light, which is parallel to each axis, assuming at least one axis passing through the center of a sphere. n pieces (
It has a shape in which a part of a sphere is cut by a set of planes (n is an integer of 2 or more), and the light incident from the spherical surface and reflected by each of the planes is concentrated after exiting the spherical surface. A condensing lens characterized in that the mutual angular relationship of the planes is maintained so that light is emitted. (2) The condensing lens according to claim 1, wherein the flat surface is finished as a reflective surface by adhering a reflective member.
