Abstract

A lighting assembly includes a transparent light guide having first and second major surfaces and a light input edge, and is configured to propagate light by total internal reflection. A light source located adjacent the light input edge is selectively operable to edge light the light guide. First light extracting elements at the first major surface are configured to extract light through the first major surface with a first light ray angle distribution. Second light extracting elements at the first major surface are configured to extract light through the second major surface with a second light ray angle distribution. The light extracted through the second major surface reduces visibility at viewing angles within a defined viewing angle range through the lighting assembly from the second major surface of the light guide greater than the reduction in visibility through the lighting assembly from the first major surface of the light guide.
