Abstract
A light assembly includes a light source and a reflector having a reflective interior surface and a central opening. A toroidal-shaped toroid optic includes a central bore and the light source is positioned in the central bore. The toroid optic is positioned within the central opening of the reflector. A broadening lens is attached to the reflector and positioned adjacent to the toroid optic. The broadening lens includes a central optic.
Claims31
A light assembly comprising:
- a. a light source;
- b. a reflector having a reflective interior surface and a central opening within which the light source is positioned;
- c. a light pipe having a proximal end and a distal end, said proximal end positioned adjacent to said light source;
- d. said light pipe adapted so that a first group of light rays produced by the light source are reflected within the light pipe and directed out of the distal end of the light pipe at angles to provide peripheral illumination;
- and
- e. wherein a second group of light rays produced by the light source reflect off of the reflective interior surface of the reflector to provide central illumination.

A flashlight comprising:
- a. a tube-shaped body;
- b. a light assembly positioned within the body including:
- i) a light source;
- ii) a reflector having a reflective interior surface and a central opening within which the light source is positioned;
- iii) a light pipe having a proximal end and a distal end, said proximal end positioned adjacent to said light source;
- iv) said light pipe adapted so that a first group of light rays produced by the light source are reflected within the light pipe and directed out of the distal end of the light pipe at angles to provide peripheral illumination;
- and
- v) wherein a second group of light rays produced by the light source reflect off of the reflective interior surface of the reflector to provide central illumination;
- c. a battery cell or pack positioned within the body;
- d. a switching assembly positioned within the body and connected to the battery cell and the light source, said switching assembly selectively permitting power from the battery cell or pack to flow to the light source.

A light assembly comprising:
- a. a light source;
- b. a reflector having a reflective interior surface and a central opening;
- c. a toroidal-shaped toroid optic including a central bore, said light source positioned in the central bore and said toroid optic positioned with the central opening of the reflector;
- d. a broadening lens attached to the reflector and positioned adjacent to said toroid optic, said broadening lens including an annular flat window portion, a near beam center-fill lens, a dome lens and a front window;
- e. said light source producing a first group of light rays that are refracted by the toroid optic, reflected by the reflective interior surface of the reflector and transmitted through the flat window portion and front window of the broadening lens to provide central illumination;
- f. said light source producing a second group of light rays that are collimated by the central bore of the toroid optic, refracted by the dome lens of the broadening lens and transmitted through the front window of the broadening lens to provide peripheral illumination.
