LED lighting fixture

1. An LED lighting fixture comprising a housing and an LED assembly secured with respect to the housing such that the LED assembly is open to air and water, the LED assembly including a plurality of LED-array modules on an equal plurality of individual heat sinks, the housing defining an air gap permitting air/water-flow to and from the heat sinks.

2. The LED lighting fixture of claim 1 wherein the heat sinks are separate structures connected with respect to the housing.

3. The LED lighting fixture of claim 2 further including at least one connection device holding adjacent pairs of the individual heat sinks with respect to one another.

4. The LED lighting fixture of claim 3 wherein the connection device is integral with at least one of the adjacent heat sinks.

5. The LED lighting fixture of claim 4 wherein the connection device holds the adjacent heat sinks in side-by-side relationship to one another.

6. The LED lighting fixture of claim 1 wherein:

the housing defines a closed chamber; and

at least one electronic driver is within the chamber.

7. The LED lighting fixture of claim 1 further including a protective cover extending over the LED assembly and secured with respect to the housing, the protective cover having perforations permitting air/water-flow therethrough.

8. The LED lighting fixture of claim 1 wherein the housing is a perimetrical structure with first and second border structures being on opposed perimetrical sides of the LED assembly and a frame structure is secured on a perimetrical side between the border structures.

9. The LED lighting fixture of claim 8 wherein the perimetrical structure is substantially rectangular and includes a pair of opposed frame structures each connected to the first and second border structures.

10. The LED lighting fixture of claim 8 wherein each heat sink has two heat -sink ends, one heat-sink end being at the first border structure and the other heat-sink end being at the second border structure.

11. The LED lighting fixture of claim 10 wherein the venting gap is between at least one of the heat-sink ends and the corresponding border structure.

12. The LED lighting fixture of claim 1 wherein each heat sink is an extrusion having a module-engaging surface and a heat-dissipating surface.

13. The LED lighting fixture of claim 12 wherein, in each heat sink, the heat-dissipating surface includes at least one fin protruding therefrom.

14. The LED lighting fixture of claim 13 further including at least one connection device holding adjacent pairs of the individual heat sinks with respect to one another.

15. The LED lighting fixture of claim 14 wherein the connection device is integral with at least one of the adjacent heat sinks.

16. The LED lighting fixture of claim 14 wherein the connection device holds the adjacent heat sinks in side-by-side relationship to one another.
