Abstract:
1. A reflector comprising: a) a reflective curve having an axis, b) wherein the reflective curve is a figure of rotation about the axis, wherein the reflective curve has a most forward radiation reflecting region essentially parallel to the axis, c) wherein the reflective curve has a first radius from its axis to the most forward region, d) wherein the reflective curve has a second radius, and the second radius is from the axis to the reflective curve in a plane rearward of the most forward region and perpendicular to the axis such that tangents to the reflective curve at its intersection with the rearward plane in a plane including the axis have an angle about 45 degrees from the rearward plane and about 45 degrees from the axis, e) wherein the reflective curve has an effective depth being the distance between the rearward plane having the second radius and a plane having the first radius, and f) wherein the reflective curve has a ratio of the second radius to the first radius being substantially greater than that of an ellipsoidal reflective curve that is a figure of rotation about the axis and having the same ratio of first radius to effective depth.
