Abstract
A light fixture comprising parabolic reflector segments therein, the lamp being located at the focal point of the segments. One segment has an arc preferably more shallow than the other segment. The window opening is angled preferably at an angle of 60 degrees to the elongate axis of the parabolic segments to provide sharper light cutoff or less spill light from one reflector segment than from the other. A shield positioned parallel to the elongate axis and on the side of the axis within the reflector segment where the cutoff characteristics are the greatest, permits primary reflected light from the lamp, while preventing direct light from the lamp to pass above the shield. The specular underside of the shield enhances light reflection therefrom while the darkened top shield surface blocks secondary reflection above the cutoff angle.
