LED lighting fixture
View Patent ↗A light fixture comprising a chamber, at least one power-circuitry driver within the chamber, at least one LED module outside the chamber, and at least one air gap between the chamber and the at least one LED module, the air gap permitting air/water-flow therethrough. The chamber is defined by a housing. The at least one LED module is on an LED heat sink outside the chamber. The housing defines the air gap permitting air/water-flow to and from the heat sink.
1. A light fixture comprising a chamber, at least one power-circuitry driver within the chamber, at least one LED module outside the chamber, and at least one air gap between the chamber and the at least one LED module, the air gap permitting air/water-flow therethrough.
2. The light fixture of claim 1 wherein the chamber is defined by a housing.
3. The light fixture of claim 2 wherein the at least one LED module is on an LED heat sink outside the chamber.
4. The light fixture of claim 3 wherein the housing defines the air gap permitting air/water-flow to and from the heat sink.
5. The light fixture of claim 3 wherein the heat sink is a separate structure connected with respect to the housing.
6. The light fixture of claim 5 wherein the housing and the heat sink define the air gap therebetween.
7. The light fixture of claim 3 wherein the heat sink is open to air/water-flow thereover.
8. The light fixture of claim 3 wherein at least one end of the heat sink is at the chamber and is open to the air gap.
9. The light fixture of claim 3 wherein the heat sink has a module-engaging surface and a heat-dissipating surface.
10. The light fixture of claim 9 wherein the heat-dissipating surface includes at least one fin protruding therefrom.
11. The light fixture of claim 3 wherein the at least one LED module includes a plurality of modules.
12. The light fixture of claim 11 wherein the heat sink comprises a plurality of interconnected heat sinks.
