Abstract
An optical system includes an outer reflector and at least one inner reflector, wherein the inner reflector is disposed within the outer reflector. The outer reflector has a proximal end, a distal end, and an interior surface extending from the distal end to the proximal end. The inner reflector has a proximal end, a distal end, and an interior surface and exterior surface extending from the distal end to the proximal end. The proximal end of the outer reflector is positioned adjacent a light source, wherein the light source is surrounded by the outer reflector's proximal end. The light source emits narrow angle beams of light through the inner reflector and emits wide angle beams of light between the outer reflector's inner surface and the inner reflector's external surface. The positioning and dimension of the inner reflector prevents the light source from emitting wide angle beams of light directly to an illuminated surface.
