Abstract

The light fixture includes a ceiling mounted, hollow support body generally comprised of pre-existing fluorescent lighting troffer, a base plate hingedbly mounted to the support body preferably via a hook/slot assembly and comprised of a heat dissipating aluminum material, a power supply unit mounted along a top of the base plate, a plurality of lighting units, each being electrically connected to the power supply unit, and each being mounted to the base plate, the plurality of lighting units each including at least one light emitting element. The lighting units are comprised of a plurality of individual strips dispersed along the bottom of the base plate for optimal heat dispersion. The base plate may have flat or angled mounting surfaces for the lighting units depending on a direction of emitted light and heat dissipation. A diffuser panel may be spaced below the lighting units and hingedbly mounted to the support body.

Claims

1. A light fixture, comprising:

a hollow support body;

a base plate mounted to said hollow support body;

a hinge means connecting one side of said base plate to said hollow support body for hinging said base plate with respect to said hollow support body;

a power supply unit mounted to said base plate; and

a plurality of lighting units, each being electrically connected to said power supply unit, and each being mounted to said base plate, said plurality of lighting units each including at least one light emitting element for emitting light.

2. The lighting fixture of claim 1, wherein said hollow support body has a top panel and a plurality of side panels extending from a peripheral edge of said top panel to define said hollow structure, said top panel being mounted to a ceiling, said base plate positioned within said hollow structure between said plurality of side panels.

3. The lighting fixture of claim 2, wherein said hollow support body is comprised of fluorescent lighting trough.

4. The lighting fixture of claim 1, wherein said base plate has a plurality of angled surfaces, said plurality of lighting units mounted on said plurality of angled surfaces.

5. The lighting fixture of claim 1, wherein said base plate is substantially flat along a mounting surface, said plurality of lighting units mounted to said flat mounting surface.

6. The lighting fixture of claim 1, wherein said hinge means includes:

a slotted structure mounted to said hollow support body;

a curved part extending from said base plate, said curved part is hingedbly received within said slotted structure for hinging said base plate with respect to said hollow support body.

7. The light fixture of claim 6, wherein said curved part is integral with said base plate, said curved part being a long edge of said base plate.

8. The light fixture of claim 1, wherein said base plate is comprised of a heat dissipating structure.

9. The light fixture of claim 8, wherein said base plate is comprised of an aluminum material.

10. The light fixture of claim 1, wherein said power supply unit is mounted along a top side of said base plate, said power supply unit being positioned within said hollow support body between said base plate and a top surface of said hollow support body, said power supply unit adapted to pivot with said base plate.

11. The light fixture of claim 1, wherein said plurality of lighting units are comprised of a plurality of individual strips dispersed along a bottom of said base plate.

12. The light fixture of claim 11, wherein each of said plurality of lighting units are attached to said base plate via a thermal adhesive compound.

13. The light fixture of claim 1, including a diffuser suspended below said plurality of lighting units, said diffuser being vertically spaced from said light emitting elements.

14. The light fixture of claim 13, wherein said diffuser is mounted to said hollow support body.

15. The light fixture of claim 14, wherein said diffuser is hingedbly mounted to said hollow support body via a second hinge means.

16. A light fixture, comprising:

a hollow support body;
