EMERGENCY LIGHT FIXTURE HAVING AN EFFICIENT REFLECTOR ASSEMBLY

摘要

An emergency light fixture includes at least two light sources and a reflector. The light sources are disposed within the reflector. The reflector includes a first concave surface formed by rotating a first parabola about a first central axis of the first parabola, a second concave surface formed by rotating a second parabola about a second central axis of the second parabola, and a third concave surface formed by translating a third parabola along a substantially straight line. The third concave surface intersects the first concave surface and the second concave surface. The light sources may be disposed at the foci of the first and second parabolas or offset from the foci. The first and second central axes may be oriented at symmetrical angles with respect to a plane bisecting the third parabola. The reflector preferably has no convex joints. The first, second, and third parabolas may be degenerated. A third light source may be disposed within the third concave surface.
