LED light fixture
View Patent ↗An LED light fixture a housing, a heat sink secured with respect to the housing, the heat sink has a base with front and back surfaces, and an LED arrangement mounted at the front surface of the heat sink The back surface of the heat sink is open to water/air flow thereover. The LED light fixture also includes at least one closed channel extending along the base and spaced therefrom for receiving wire connections for the LED arrangement. The at least one closed channel receives wiring extending to/from the second LED module. The LED arrangement may include at least first and second LED modules, the first LED module being proximal to the housing with the at least one closed channel receiving wiring extending to/from the second LED module. The first and second LED modules may be in end-to-end relationship to one another such that the second LED module is distal from the housing.
1. An LED light fixture comprising:
a housing;
a heat sink secured with respect to the housing and having a base with front and back surfaces, the back surface being open to water/air flow thereover;
an LED arrangement at the front surface of the heat sink; and
at least one closed channel extending along the base and spaced therefrom for receiving wire connections for the LED arrangement.
2. The LED light fixture of claim 1 wherein:
the LED arrangement comprises at least first and second LED modules, the first LED module being proximal to the housing; and
the at least one closed channel receives wiring extending to/from the second LED module.
3. The LED light fixture of claim 2 wherein the first and second LED modules are in end-to-end relationship to one another such that the second LED module is distal from the housing.
4. The LED light fixture of claim 3 wherein the housing comprises a wire-access(es) receiving wires to/from the first LED module proximal to the housing.
5. The LED light fixture of claim 4 wherein the housing and the heat sink define at least one venting gap therebetween.
6. The LED light fixture of claim 2 wherein the at least one closed channel extends along the back surface of the base.
7. The LED light fixture of claim 6 wherein the least one closed channel is at least partially formed by the heat sink.
8. The LED light fixture of claim 7 wherein the heat sink includes parallel fins extending from the back surface, the least one elongate channel being formed along the fin(s).
9. The LED light fixture of claim 7 wherein the heat sink is an extrusion forming the at least one elongate closed wiring channel therealong.
10. The LED light fixture of claim 2 further comprising at least one venting gap therebetween the housing and the heat sink.
11. The LED light fixture of claim 10 wherein the housing comprises a wire-access(es) receiving wires from the first LED module proximal to the housing.
12. The LED light fixture of claim 10 further comprising at least one venting aperture through the base.
13. The LED light fixture of claim 12 wherein the at least one closed channel extends along the back surface of the base.
14. The LED light fixture of claim 13 wherein the least one closed channel is at least partially formed by the heat sink.
15. The LED light fixture of claim 14 wherein the heat sink includes parallel fins extending from the back surface, the least one elongate channel being formed along the fin(s).
16. The LED light fixture of claim 14 wherein the heat sink is an extrusion forming the at least one elongate closed wiring channel therealong.
17. The LED light fixture of claim 1 wherein the heat sink is an extrusion forming the at least one elongate closed wiring channel therealong.
18. The LED light fixture of claim 17 wherein the heat sink includes parallel fins extending from the back surface, the least one elongate channel being formed along the fin(s).
19. The LED light fixture of claim 1 wherein the housing includes a closed chamber enclosing at least one LED driver.
