Abstract
A light directing apparatus includes an optical substrate having first and second sides, a compound lens outer surface (CLOS) on a first portion of the first side, and first and second protrusions on a second portion of the first side. The CLOS is in optical communication with the second side, the CLOS having mirror image symmetry about a medial plane that contains a centerline of the CLOS. The first protrusion is disposed proximate the CLOS, and in optical communication with the second side. The second protrusion is disposed proximate the first protrusion, and in optical communication with the second side. The first protrusion is disposed between the second protrusion and the CLOS. The first and second protrusions each have a curved apex such that first and second planar section cuts through the optical substrate perpendicular to the medial plane cut twice through each curved apex.
