Abstract

Suspended ceilings of buildings incorporate a T-bar component which is used to provide an integral lighting system. The T-bar component serves as the backbone or a housing member of the lighting fixture as well as an integral part of the suspended ceiling framework.

Claims

1. ) A lighting fixture incorporating a T-bar component for a suspended ceiling lighting system, comprising:

(a) a housing, including a T-bar component;

(b) electric light emitting bulb means carried within said housing; and

(c) reflector means carried by said housing for directing light emitted by said bulb beams in at least one direction away from said bulb means.

2. ) The lighting fixture of claim One, wherein said light-emitting bulb means includes at least one fluorescent bulb.

6. ) A lighting fixture of claim One or claim 2, wherein said bulb means comprises a series of light emitting diodes.

7. ) A light fixture of claim One or claim 2, wherein the bulb means comprise a series of light emitting diodes;

and said refractor means comprises first and second luminous transparent panels, said primary panel being secured on one side of said housing, and the second of said primary panels being secured on another side of said housing, said primary panel having first and second sides, each of said sides defining one, flat, continuous surface there across.

3. ) The lighting fixture of claim One, further comprising ballast means disposed within said T-bar.

4. ) A lighting fixture of claim Two, further comprising ballast means disposed within said T-bar.

5. ) A lighting fixture incorporating a T-bar component for a suspended ceiling lighting system, comprising:

(a) a housing, including a T-bar component;

(b) electric light emitting bulb means carried within said housing;

(c) reflector means extending from said housing;

(d) a primary reflector panel, selectively, pivotably, secured to said housing to direct light emitted from said bulb in the direction of said ceiling; and

(e) Secondary refractor means including a plurality of ceiling tile means proximately disposed in said suspended ceiling and adjacent said primary refractor panel for re-directing light emitted from said bulb means and said primary reflector panel in directions away from said ceiling.

8. ) The lighting fixture of claim One, wherein the bulb means comprises at least one member of the group consisting of light-emitting diodes, a fluorescent bulb, and an incandescent light bulb.

9. ) A lighting fixture incorporating a T-bar component for a suspended ceiling lighting system comprising:

(a) a housing, including a T-bar component;

(b) track means carried by said housing for receipt of at least one track light head thereon, and selectively movable thereon.

10. ) The lighting fixture of claim Nine, further comprising refractor means carried by each of said track light heads and bulb means securable within said track light heads said refractor means, directing light emitted by said bulb means within said track light head, in at least one direction away from said lighting fixture.

11. ) A lighting fixture incorporating a T-bar component for a suspended ceiling lighting system, comprising:

(a) a housing, including a T-bar component;

(b) electric light emitting bulb means carried within said housing;

(c) reflector means carried by said housing for directing light emitted by said bulb beams in at least one direction away from said bulb means; and

(d) refractor means carried by said housing for directing light emitted by said bulb means in at least one direction away from said bulb means.
