ABSTRACT:
BACKGROUND OF THE INVENTION
Recessed lighting fixtures typically include a frame attached to a structure such as a joist above the ceiling surface. One or more light elements are disposed in a reflector held by the frame that opens into the ceiling. Although it may include holes in which the light elements are secured and replaced, the reflector is typically an otherwise enclosed structure so that it defines a recess extending upward into a ceiling.
Generally, the reflector body is cylindrically shaped and has a flat top surface opposite the reflector's opening. Because of the flat top surface and placement of the light element near the top of the reflector, light is often trapped in the reflector. Thus, looking straight up into such a fixture, the reflector's top inside surface often appears dark.
SUMMARY OF THE INVENTION
The present invention recognizes and addresses the foregoing disadvantages, and others, of prior art construction and methods.
Accordingly, it is an object of the present invention to provide an improved recessed light fixture.
It is a still further object of the present invention to provide a reflector for a ceiling recessed light fixture having an improved efficiency and light output.
Some of these objects are achieved by a reflector for a light fixture having elongated light elements, wherein the light fixture opens at the ceiling surface and is recessed thereabove and wherein the reflector comprises a generally cylindrical bottom section defining a circular opening and a substantially enclosed top section defining a generally rectangular, corrugated top surface and a side portion tapering inwardly from the bottom section to the top surface.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate one or more embodiments of the invention and, together with the description, serve to explain the principles of the invention.
