Abstract

A lighting fixture utilizing light emitting diodes and easily reconfigurable lenses to provide customizable lighting patterns to more efficiently illuminate work or storage areas.

Claims

1. An LED lighting fixture comprising:

a fixture base;

a printed circuit board including;

a light emitting diode; and

a bezel mounted on said base, including,

a lens disposed in relation to said light emitting diode to provide a light output pattern characterized by a specific illumination footprint.

2. The LED lighting fixture of claim 1 wherein the bezel includes multiple lenses.

3. The LED lighting fixture of claim 1 wherein the lens comprises a round lens.

4. The LED lighting fixture of claim 1 wherein the lens comprises a cat-eye lens.

5. The LED lighting fixture of claim 1 wherein the lens comprises a bilateral lens.

6. The LED lighting fixture of claim 1 wherein the lens is a composite of multiple lens types.

7. The LED lighting fixture of claim 1 wherein the bezel comprises a combination of lens.

8. The LED lighting fixture of claim 1 wherein the LED lighting fixture includes multiple bezels to produce multiple light output patterns resulting in a composite illumination footprint.

9. The LED lighting fixture of claim 8 wherein the illumination footprint directs light to areas of desired illumination while not directing light to areas not of desired illumination.

10. The LED lighting fixture of claim 8 wherein the bezels and lenses produce an illumination footprint that corresponds to an area of desired illumination.

11. The LED lighting fixture of claim 1 wherein the fixture base includes a bezel flange to retain the bezel.

12. The LED lighting fixture of claim 1 wherein the fixture base includes a mounting flange.

13. The LED lighting fixture of claim 1 wherein fixture base includes a fastener receiver.

14. The LED lighting fixture of claim 13 including a fastener for securing the end cap to the fixture base.

15. The LED lighting fixture of claim 14 further comprising an end cap which serves to secure the bezel and support in place so as to hold the lens disposed in relation to said light emitting diode to provide a light output pattern characterized by a specific illumination footprint.

16. The LED lighting fixture of claim 15 including a bezel gasket for securing the bezels together in a manner as to prevent infiltration of debris.

17. The LED lighting fixture of claim 12 further comprising a mounting clip secured to the fixture base for use in mounting the LED lighting fixture.

18. The LED lighting fixture of claim 1 wherein the light emitting diode comprises multiple light emitting diodes.

19. The LED lighting fixture of claim 1 wherein the light emitting diodes are powered by direct current electricity controlled through an interactive system.

21. A method of reconfiguring the illumination footprint of an LED light fixture of claim 7, comprising the step of exchanging one type of lens for another.

20. An LED lighting fixture comprising:

a base fixture, comprising;

a mounting flange,

a bezel flange,

a fastener receiver,

an end cap;

a fastener;

a bezel gasket;

a printed circuit board comprising;

a light emitting diode, mounted on said printed circuit board,

a electrical conductor;

a bezel, mounted on said base fixture, comprising

a lens mounted in said bezel and disposed in relation to said light emitting diode to provide a light output pattern characterized by a specific illumination footprint.
