Abstract

The present application is directed to a light fixture and associated retrofit lighting kit that includes a substantially flat light emitting diode panel. The light fixture can be employed in a variety of applications, including installation as a standalone fixture, a replacement for a fluorescent lighting unit and as a retrofit lighting kit to be used in connection with an existing fluorescent lighting unit.

Claims (15)

1. A light fixture comprising:

a frame including a bottom assembly and a top assembly coupled to the bottom assembly, the bottom assembly and the top assembly cooperating to form a plurality of channels within the frame;

a substantially flat light emitting diode (LED) panel disposed within the frame; and

power circuitry disposed within the frame or adjacent the frame, the power circuitry being configured to electrically couple the substantially flat LED panel to an external power supply;

wherein the bottom assembly includes a back surface and a plurality of mounting tabs on the back surface, wherein the mounting tabs are movable between (i) a first unextended position where the mounting tabs are substantially co-planar with the back surface, (ii) a first extended position where the mounting tabs extend out at an angle of approximately 90 degrees relative to the back surface, and (iii) a second extended position where the mounting tabs extend out at an angle of approximately 180 degrees relative to the back surface.

2. The light fixture of claim 1 , wherein the mounting tabs are integrally formed with the back surface of the bottom assembly.

3. The light fixture of claim 1 , wherein the mounting tabs are formed as a cut-out from the back surface of the bottom assembly.

4. The light fixture of claim 1 , wherein the mounting tabs are operatively coupled to the back surface of the bottom assembly.

5. The light fixture of claim 1 , wherein the mounting tabs define an aperture configured to receive a fastener.

6. The light fixture of claim 1 , wherein the mounting tabs are configured to remain in position when moved to the first extended position or when moved to the second extended position.

7. The light fixture of claim 1 ,

wherein said substantially flat light emitting diode (LED) panel has a thickness less than about 1.0 inches.

8. The light fixture of claim 1 , wherein the substantially flat LED panel includes a plurality of LEDs disposed adjacent at least one edge of the frame.

9. The light fixture of claim 1 , wherein the frame of the light fixture has a thickness of less than about 0.5 inches.

10. The light fixture of claim 1 , wherein the power circuitry comprises a transformer.
