ABSTRACT:
A nonimaging light assembly for flashlights, including a light source and a lens symmetrical about an optical axis for receiving light from the light source and producing therefrom a light beam having concentrated and divergent components resulting in a high intensity core beam surrounded by a smoothly transitioning lower intensity surround beam. In a preferred embodiment utilizing a light emitting diode as the light source, the combined light beam produced by the light assembly has a substantially circular cross section. In a preferred embodiment including a hybrid LED light source having a white-light die and an infrared die, a lens optimized with the white-light die produces a satisfactory IR beam having concentrated and divergent components when used with the IR die.
