Abstract
A lighting assembly includes a light guide to propagate light by total internal reflection. A reflector adjacent the second major surface of the light guide includes a reflective surface to reflect extracted light back into the light guide. An anti-wetting component is interposed between the light guide and the reflector and includes opposed major surfaces. At least one of the major surfaces of the anti-wetting component has a high surface roughness. The anti-wetting component is configured to redirect light transmitted therethrough such that an intensity profile of the light output from the first major surface of the light guide is uniform among a first location where the anti-wetting component is in contact with the light guide and the reflector and a second location where the anti-wetting component is not in contact with at least one of the light guide and the reflector.
