1. A condensing array comprising:

  • a plurality of condensing elements;

    at least one light source positioned proximate to the condensing elements to transmit light into a first section of at least one of the condensing elements which are arranged with respect to the at least one light source to angularly condense the light;

    at least one of the condensing elements having a first section that provides substantially total internal reflection of light entering at a base of the first section and a second section which 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.
