Lens-reflector combination for batwing light distribution
Abstract:
The present subject matter is directed to a system and method for producing a batwing light distribution. A lens is illuminated with a light source, preferably an LED, and the lens is configured to internally reflect a portion of the illuminating light back in a direction generally opposite to the initial illumination direction. Another portion of the light from the light source may pass through other lens surfaces but may also be reflected back past the light source with a reflector positioned on the other side of the lens from the light source. The light source may be mounted on a frame so as to obscure light therefrom from view.
