Abstract

A lighting fixture is provided. The lighting fixture may include one or more circuit boards having a plurality of LED light sources. The lighting fixture may further include one or more lens assemblies coupleable to the one or more circuit boards. The one or more lens assemblies may include a frame defining a plurality of openings. The one or more lens assemblies may further include a plurality of lenses molded to the frame. The plurality of lenses may be molded to the frame such that each of the plurality of lenses is at least partially positioned within a corresponding opening of the plurality of openings defined by the frame.

First claim

What is claimed is:

1. A lighting fixture, comprising:
one or more circuit boards comprising a plurality of light emitting diode (LED) light sources; and
one or more lens assemblies coupleable to the one or more circuit boards, the one or more lens assemblies comprising:
a frame defining a plurality of openings; and
a plurality of lenses molded to the frame such that each of the plurality of lenses is at least partially positioned within a corresponding opening of the plurality of openings defined by the frame.

2. The lighting fixture of claim 1 , wherein when the one or more lens assemblies are coupled to the one or more circuit boards, each of the plurality of lenses is in optical communication with a corresponding LED light source of the plurality of LED light sources.

3. The lighting fixture of claim 1 , wherein the one or more circuit boards are positioned on a surface associated with the lighting fixture.

4. The lighting fixture of claim 3 , wherein the surface is associated with a housing of the lighting fixture.

5. The lighting fixture of claim 3 , wherein when the one or more lens assemblies are coupled to the one or more circuit boards, the one or more circuit boards are positioned between the surface and the one or more lens assemblies.

6. The lighting fixture of claim 1 , wherein the one or more lens assemblies further comprises:
a gasket molded to the frame.

7. The lighting fixture of claim 6 , wherein:
each of the plurality of lenses is molded to a top surface of the frame; and
the gasket is molded to a bottom surface of the frame.

8. The lighting fixture of claim 6 , wherein the gasket comprises a wiper gasket.

9. The lighting fixture of claim 6 , wherein when the one or more lens assemblies are coupled to the one or more circuit boards positioned on a surface associated with the lighting fixture, the gasket seals against the surface or the one or more circuit boards to provide a seal between the one or more circuit boards and an external environment surrounding the housing of the lighting fixture.

10. The lighting fixture of claim 1 , wherein:
the frame comprises a plurality of mounting flanges, each of the plurality of mounting flanges defining a mounting hole.

11. The lighting fixture of claim 10 , wherein the plurality of mounting flanges comprises:
a first group of mounting flanges disposed on an outer portion of the frame; and
a second group of mounting flanges disposed on an inner portion of the frame.

12. The lighting fixture of claim 1 , wherein the one or more lens assemblies are coupleable to the circuit board via a plurality of fasteners.

13. The lighting fixture of claim 10 , wherein when the one or more lens assemblies are coupled to the one or more circuit boards via a plurality of fasteners, each of the plurality of fasteners extends through the mounting hole defined by a corresponding mounting flange of the plurality of mounting flanges.

14. The lighting fixture of claim 1 , wherein the frame comprises a polycarbonate material.

15. The lighting fixture of claim 1 , wherein each of the plurality of lenses comprises a silicone material.

16. A lens assembly coupleable to a circuit board comprising a plurality of light emitting diode (LED) light sources, the lens assembly comprising:
a frame defining a plurality of openings; and
a plurality of lenses molded to the frame such that each of the plurality of lenses is at least partially positioned within a corresponding opening of the plurality of openings defined by the frame,
wherein when the lens assembly is coupled to the circuit board, each of the plurality of lenses is in optical communication with a corresponding LED light source of the plurality of LED light sources.

17. The lens assembly of claim 16 , wherein the lens assembly further comprises:
a gasket molded to the frame.

18. The lens assembly of claim 17 , wherein:
each of the plurality of lenses is molded to a top surface of the frame; and
the gasket is molded to a bottom surface of the frame.

19. The lens assembly of claim 16 , wherein the gasket comprises a wiper gasket.

20. The lens assembly of claim 16 , wherein the frame comprises a polycarbonate material.

21. The lens assembly of claim 16 , wherein the plurality of lenses comprises a silicone rubber.
