<p>A separation optics structure (10) comprising a transparent unitary body portion extending between a first wide end (23) and a second distal end (25) defines a wedge-shaped structure. The body portion (14) includes a front portion defining a generally planar front illumination surface (22), a back portion (12) having a plurality of beveled redirecting facets (20) spaced apart by intermediate areas (18), and a plurality of optics elements (60) disposed within the intermediate areas (18). A first light source (26) is coupled at the wide end (23) to transmitted light longitudinally through the body portion toward the redirecting facets (20). The redirecting facets (20) having reflective surfaces (30) transverse to the planar front illumination surface (22) to reflect and scatter the light (28) toward the front surface in a relatively low intensity light distribution. A second light source (34) is coupled adjacent the back portion (12) behind the intermediate areas (18). The optics elements (60) transmit the light (38) directly through the intermediate areas (18) toward the front surface (14) in a relative high intensity light distribution. The optics elements (60) may also include concave, convex and/or facet for shaping the direct light toward the front illumination surface (22).</p> |
