Abstract: A light guide is configured to direct light from a light source. The light guide has an outer guide member and an inner guide member located in the outer guide member. A light passage is defined through the light guide between the inner and outer guide members. When a first end of the light guide is positioned adjacent a light source, light is permitted to pass from the light source through only the light passage in the light guide. The configuration of the light guide reduces passage of light off-angle to the length of the light passage through the guide, such that light is directed substantially parallel to the light passage. The light guide is thus effective in eliminating light dispersion and associated light banding and in focusing light upon a particular object or area.
