Abstract
A reflector with focused output is disclosed. The reflector comprises a reference parabolic portion and a plurality of non-reference parabolic portions. A focal length of the plurality of non-reference parabolic portions is determined from a focal length of the reference parabolic portion. In one embodiment, the focal length of the plurality of non-reference parabolic portions is a perpendicularly projected distance from a focus of the reference parabolic portion onto a central axis of the plurality of non-reference parabolic portions. In one embodiment, the focal lengths of the reference parabolic portion and the plurality of non-reference parabolic portions are scaled by a constant. A method of designing a reflector and an obstruction light that uses the reflector is also disclosed.
