Zusammenfassung:	A light guide element 100 for controlling light distribution includes a light-incident surface 112 , a light-emitting surface 114 , a first reflecting surface 116 , and a second reflecting surface 118 . The light-incident surface includes a first outer peripheral edge 112a and a first inner peripheral edge 112b . The light-emitting surface includes a second outer peripheral edge 114a and a second inner peripheral edge 114b . The first reflecting surface is constructed by a first profile curve, and connects the first and the second outer peripheral edge. The first profile curve is a connecting line of two points respectively on the first outer peripheral edge and the second outer peripheral edge. The second reflecting surface is constructed by a second profile curve, and connects the first and the second inner peripheral edge. The second profile curve is a connecting line of two points respectively on the first inner peripheral edge and the second inner peripheral edge.
