Abstract
LED light assembly includes a lens centered on its optical axis and a parabolic reflector with a polygonal periphery, such reflector positioned to surround the lens and configured to reflect light into a direction substantially parallel to the optical axis. The lens includes a light entry surface, a light emission surface, and a non-circular bypass surface extending between the light entry and emission surfaces.
