Abstract:
1. A flashlight, comprising: an illuminator assembly including an LED, a flange, and a parabolic reflector; a lens comprising a convergent portion, a nonconvergent portion, and a lens flange, wherein the convergent portion is characterized by a focal point; and a housing conformingly receiving the illuminator assembly so as to contain the illuminator assembly within the housing; wherein the LED has a light emitting element, a parabolic micro-reflector and a transparent tip, the LED configured to emit light from its light emitting element and produce by reflection from the parabolic micro-reflector a divergent beam of light that is characterized by an optical directivity angle extending from a vertex point, and also to produce additional light extending in a direction outside of the divergent beam of light and emanating from the tip of the LED; wherein the parabolic reflector is configured such that the focal point of the parabolic reflector coincides with the transparent tip of the LED; wherein the flange is configured to engage the lens flange to position the LED so that the light emitting element is positioned at the focal point of the convergent portion and the divergent beam is centered on the focal center point of the convergent portion; wherein substantially all of the divergent beam of light from the LED passes through the convergent lens to emerge in a first beam of parallel light; and wherein the parabolic reflector reflects at least a portion of the additional light into a second beam of parallel light that is parallel to the first beam of parallel light and extending through the nonconvergent portion of the lens.
