Patent ID: 8226262

Claim:
A condensing element comprising: a plurality of first sections that provides substantially total internal reflection of light entering at a base of each of the plurality of the first sections; a second section which tapers from each of the first sections towards an optical axis of the element extending through the second section to output light from the plurality of first sections, the plurality of first sections and the 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 each of the first sections, wherein the bases of the plurality of first sections are provided about the optical axis; an array of light sources positioned proximate to the base of each of the plurality of first sections, wherein at least one light source of the array of light sources is provided at the base of each of the plurality of first sections to transmit light into the respective first section of the condensing element; and at least one transparent layer of polymer material in between and in optical contact with the array of light sources and the condensing element.
