Abstract

A convertible lighting fixture includes a first housing defining a first compartment, a second housing defining a second compartment and movably attached to the first housing, the second housing having a surface adjacent the first compartment. The lighting fixture further includes a mounting plate attached to the second housing and at least partially separating the second compartment from a third compartment, a light source mechanically attached to the mounting plate and electrically connected to a power source disposed within the first compartment, and a cover defining the third compartment and substantially surrounding the light source, the cover reversibly attached to the second housing opposite the first housing, where the first, second, and third compartments are arranged to thermally insulate the power source from the light source.

Claims

1. A lighting fixture, the lighting fixture comprising:

a first housing defining a first compartment;

a second housing defining a second compartment and movably and removably attached to the first housing, the second housing having a surface adjacent the first compartment; and

a cover reversibly attached to the second housing opposite the first housing, the cover defining a third compartment thermally insulated from the first compartment by the second compartment.

2. The lighting fixture of claim 1, the lighting fixture further comprising:

a plate attached to the second housing and at least partially separating the second compartment from a third compartment; and

a light source mechanically attached to the plate and electrically connected to a power source disposed within the first compartment.

3. The lighting fixture of claim 1, wherein the first, second, and third compartments are configured to enable the light source within the third compartment to be replaced without accessing the first or second compartments.

4. The lighting fixture of claim 1, wherein the first, second, and third compartments are configured to enable the power source within the first compartment to be replaced without accessing the second or third compartments.

5. The lighting fixture of claim 1, the lighting fixture further comprising at least one slip hinge, removably attaching the first and second housings, and a locking screw attached to either the first or second housings and disposed adjacent the at least one slip hinge, whereby the locking screw prevents disassembly of the slip hinge.

6. The lighting fixture of claim 1, wherein the cover comprises a plurality of optical elements capable of directing light emitted by the light source into a desired light distribution.

7. The lighting fixture of claim 1, wherein the plate is adapted to enable the attachment of different types of light sources.

8. The lighting fixture of claim 1, wherein the light source is a fluorescent induction tube disposed within at least one induction coil.

9. The lighting fixture of claim 8, wherein the power source is a ballast.

10. The lighting fixture of claim 1, wherein the light source is at least one light-emitting diode module.

11. The lighting fixture of claim 10, wherein the power source is a light-emitting diode driver, including voltage and current control.

12. A convertible lighting fixture, the convertible lighting fixture comprising:

a first housing defining a first compartment;

a second housing defining a second compartment and movably and removably attached to the first housing, the second housing having a surface adjacent the first compartment;

a mounting plate attached to the second housing and at least partially separating the second compartment from a third compartment;

a light source mechanically attached to the mounting plate and electrically connected to a power source disposed within the first compartment; and

a cover defining the third compartment thermally insulated from the first compartment by the second compartment and substantially surrounding the light source, the cover reversibly attached to the second housing opposite the first housing;

wherein the first, second, and third compartments are configured to enable the power source within the first compartment to be replaced without accessing the second or third compartments.

13. The convertible lighting fixture of claim 12, wherein the mounting plate is adapted to enable the attachment of different types of light sources.

14. The convertible lighting fixture of claim 12, wherein the first, second, and third compartments are configured to enable the light source within the third compartment to be replaced without accessing the first or second compartments.

15. The convertible lighting fixture of claim 12, wherein the light source is a fluorescent induction tube disposed within at least one induction coil.

16. The convertible lighting fixture of claim 15, wherein the power source is a ballast.

17. The convertible lighting fixture of claim 12, wherein the light source is at least one light-emitting diode module.

18. The convertible lighting fixture of claim 17, wherein the power source is a light-emitting diode driver, including voltage and current control.

19. The convertible lighting fixture of claim 12, the convertible lighting fixture further comprising an isolation plate attached to the surface of the second housing and disposed within the first compartment, wherein the power source is attached to the isolation plate.

20. The convertible lighting fixture of claim 12, further comprising at least one slip hinge, removably attaching the first and second housings, and a locking screw attached to either the first or second housings and disposed adjacent the at least one slip hinge, whereby the locking screw prevents disassembly of the slip hinge.
