ABSTRACT:
A reflector includes a first concave surface, a second concave surface and a third concave surface. The first concave surface has a first axis and a first opening to receive a first light source. The first concave surface is configured to reflect first light rays of the first light source from the first concave surface across the first axis and not to reflect second light rays of the first light source from the first concave surface. The second concave surface has a second axis and a second opening to receive a second light source. The second concave surface is configured to reflect first light rays of the second light source from the second concave surface across the second axis and not to reflect second light rays of the second light source from the second concave surface. The third concave surface translates along a substantially straight line to intersect the first concave surface and the second concave surface such that the first light rays of the first and second light sources contribute to an interior lighted portion of a lighted pathway that is defined by a combination of the first and second light rays of the first and second light sources.
