Each grouping includes a first micro-optical element and a second micro-optical element adjacent the first micro-optical element and arranged along a light propagation path extending from the light input edge. In some embodiments, the second micro-optical element is configured to redirect at least a portion of light propagating along the light propagation path and incident thereon toward the first micro-optical element such that the redirected light is incident the first micro-optical element and extracted from the light guide. In other embodiments, the second micro-optical element is configured to redirect at least a portion of the propagating light incident thereon away from the first micro-optical element. | 02-04-2016 |
| 20160124135 | OPTICAL WAVEGUIDE BODIES AND LUMINAIRES UTILIZING SAME - A waveguide body comprises a length from a first end to a second end. The waveguide body further comprises a central section extending along the entire length of the waveguide body and comprising a first thickness. First and second opposed side sections extend away from the central section along the length of the waveguide body and comprise second and third thicknesses, respectively, less than the first thickness. A coupling portion is located in the central section, wherein the coupling portion comprises first and second coupling surfaces defining at least in part an elongate coupling cavity extending along the length of the waveguide body. The coupling portion further comprises first and second control surfaces, and the first and second coupling surfaces are configured to direct light onto the first and second control surfaces. The first and second control surfaces are configured to direct light into at least one of the first and second side sections. The side sections comprise optical features to extract light out opposing sides of the at least one side section as the light propagates through the at least one side section. | 05-05-2016 |
