ABSTRACT:
A light source is combined with an optic and a reflector. Light incident onto to the reflector is reflected with a single reflection. The reflector occupies a portion of a solid angle around the light source to the exclusion of the optic at least with respect to any optical function. The reflector directly receives a second portion of light. The optic occupies substantially all of the remaining portion of the predetermined solid angle to directly receive a first portion of light from the light source. A reflected beam from the reflector is reflected into a predetermined reflection pattern. The inner and/or outer surface of the optic is shaped to refract or direct light which is directly transmitted into the optic from the light source from a first portion of light and/or reflected into the optic from the reflector from the reflected beam into a predetermined beam.
