Abstract: A lighting fixture includes a light source, a lamp case, a power supply device, a shaped reflector and a prism. The shaped reflector has inwardly curved front and back walls each consisting of multiple conical faces abutted against one another and sloping at different angles. The angle of inclination of one lower conical face is relatively closer toward the center of the shaped reflector than that of the adjacent upper conical face. Thus, the shaped reflector effectively and evenly reflects the light emitted by the light source onto a predetermined rectangular or particularly shaped illumination area. Therefore, the lighting fixture is practical for road illumination, lounge illumination, advertizing light box and streamline table light applications to effectively and evenly illuminate the desired area, saving much power consumption.
