Abstract

In an embodiment of an LED light fixture, the fixture includes a housing defining a chamber and an LED module that is outside the chamber and adjacent to the housing. The LED module includes a mounting board with a plurality of LED packages mounted thereon and a cover over the mounting board. The cover and the mounting board together form a module interior and the cover is configured to expose the LED packages. The improvement in this light fixture includes a rigid wireway between the LED module and the housing and defining a passageway between the module interior and the chamber.

Claims

1. In an LED light fixture including (a) a housing defining a chamber and including an aperture, (b) an LED module outside the chamber and adjacent to the housing and including (b1) a mounting board with a plurality of LED packages mounted thereon and (b2) a cover over the mounting board, forming a module interior and configured to expose the LED packages, the improvement comprising a rigid wireway between the LED module and the housing and defining a passageway between the module interior and the chamber, said rigid wireway including a distal end in sealing engagement about said aperture.

2. The LED light fixture of claim 1 wherein the rigid wireway is integral with the LED module.

3. The LED light fixture of claim 1 wherein the rigid wireway is integral with the cover.

4. The LED light fixture of claim 1 wherein the passageway between the interior and the chamber is water-tight.

5. The LED light fixture of claim 4 wherein the rigid wireway is integral with the LED module.

6. The LED light fixture of claim 5 wherein the rigid wireway is integral with the cover.

7. The LED light fixture of claim 6 wherein the cover includes a main planar Portion and an edge portion therearound and extending toward the mounting board, the integrally-formed rigid wireway extending from the edge portion toward the housing.

8. The LED light fixture of claim 1 further including a gasket layer disposed within the module interior and being configured to expose the LED packages.

9. The LED light fixture of claim 8 wherein the gasket layer is a sponge gasket.
