ABSTRACT:
A reflector for a fluorescent fixture having an elongate generally cylindrically concave inner surface defining a cavity shaped so that all portions of a fluorescent lamp along the reflectivity axis are within the cavity. The inner surface of the reflector includes a specularly reflective major central portion that reflects a major portion of light emitted from the lamp generally normal to an imaginary plane across an outlet side of the cavity to illuminate an area beneath the fixture, and opposite reflective signal portions adjacent opposite sides of the reflector that each direct a minor portion of the light emitted by the lamp across the open side of the cavity and past the opposite edge of the inner surface to indicate to persons spaced from the illuminated area that the fluorescent lamp is emitting light.
