<p>Illumination assemblies and systems using same are disclosed. The illumination assembly can include a reflective substrate, and a light source unit including one or more light sources capable of producing illumination light. The assembly can further include a first light extraction surface including an azimuthal beam widening topography, where the first light extraction surface is positioned such that the light source unit is between the first light extraction surface and the reflective substrate. The first light extraction surface can face the light source unit.</p> |
