Abstract
An optic assembly has a reflector with a reflective surface, one or more light sources, and a mask with one or more apertures. Facets on the reflective surface direct light rays so that a substantial portion of the light rays within the optic assembly can be managed as if they were emitted from a focal point located outside the optic assembly.
