    摘要: A non-imaging lens includes a transparent member, a conical protrusion and a plurality of annular protrusions. The transparent member includes a first surface and a second surface. The first surface and the second surface are planar. The conical protrusion is defined on the first surface. The annular protrusions are concentrically defined on the first surface around the conical protrusion. Each of cross-sections of the annular protrusions approximately forms a right-angled triangle. The triangle includes a first angle, a second angle, a bottom surface, a first surface and a second surface. The first angle exceeds the second angle. The first angle is less than or equal to 90°. The bottom surfaces of the triangles increase in turn outwards from the conical protrusion.
