Abstract
A TIRing condensing array includes a plurality of condensing elements with at least one of the condensing elements having a first section and a second section. The first section provides substantially total internal reflection of light entering at a base of the first section. The second section tapers from the first section towards an optical axis extending through the first and second sections. The first and second sections are configured so a half-power angle of the light output from the second section is less than the half-power angle of the light entering the first section. At least one of the condensing elements is optically and mechanically connected to at least one other of the condensing elements at an attachment area between the condensing elements.
