ABSTRACT:
The rectangular reflector has lateral reflective portions and instead of having upper and lower planar fill-in portions which can result in undesirable reflections, has upper and lower reflective portions which are constituted by an infinite number of non-circular, e.g. parabolic or elliptical, curves. These curves extend forwardly of the reflector body to terminate at the front opening thereof. The curves have foci and focal axes which are coincident and increase progressively in focal length from the center of the reflector to the lateral reflective portions. Such a reflector has improved light collection and light spreading properties.
