摘要：A nonimaging light assembly for flashlights, including a light source and a lenssymmetrical about an optical axis for receiving light from the light source and producingtherefrom a light beam having concentrated and divergent components resulting in ahigh intensity core beam surrounded by a smoothly transitioning lower intensity
surround beam. In a preferred embodiment utilizing a light emitting diode as the lightsource, the combined light beam produced by the light assembly has a substantiallycircular cross section.
