Abstract: Headlights wherein one or more parameters associated with the illumination provided by the associated light source are described. Parameters that can be adjusted, for example, include the intensity of light exiting the headlight assembly, the dispersion of light emitted from the headlight, the direction of illumination, and the like.

Abstract: Flashlight bezels, which comprise a bezel, lens, and a thermal conductor disposed in and through the lens so as to be positioned conduct heat from a light source positioned to one side of the lens to space on the opposite side of the lens, are described. When included in a flashlight, the thermal conductor portion of the bezel becomes associated with the light source so that heat generated by the light source, when energized, can be efficiently transferred to the environment, for example, water, in which the flashlight is being used. By so doing, the efficiency of the light source can be maintained, the service life of the light source may be extended, etc.

Abstract: Systems, methods and devices for lighting are provided with a reflector with paraboloidal segments. One lighting system includes a reflector having one or more reflector segments. Each reflector segment is substantially paraboloidal and has a central axis of symmetry. The lighting system also includes an illumination portion having one or more light sources. Each light source corresponds to one of the reflector segments and has a central illumination axis. The central illumination axis is directed toward the corresponding segment and substantially perpendicular to the central axis of symmetry of the corresponding segment.

Abstract: An efficient system and method for zooming the light from a flashlight is disclosed. Multiple refractive lenses are translated in unison to allow zooming of the light while reducing the size and weight of the required lenses. In another aspect, a meniscus lens is used to reduce the amount of light lost from a light-emitting diode (LED). One method includes providing a light source in a housing and translating a lens arrangement substantially along a light path of a light beam generated by the light source. The lens arrangement includes at least two refractive lenses separated by a gap, a size of the gap being maintained during translation of the lens arrangement.
