LED luminaire having enhanced thermal management
In one aspect, luminaires are described herein having sensor modules integrated therein. In one aspect, a luminaire described herein comprises a light emitting face including a LED assembly. A sensor module is integrated into the luminaire at a position at least partially overlapping the light emitting face. In another aspect, a luminaire described herein comprises a LED assembly and a driver assembly. A sensor module is integrated into the luminaire along or more convective air current pathways cooling the LED assembly or driver assembly.
1. A luminaire comprising:
a driver assembly comprising a driver heatsink having an interior in which a circuit board assembly is positioned; and
a LED assembly comprising an array of light emitting diodes and a heatsink, wherein the driver assembly is vertically integrated over an aperture in the LED assembly to divide an air flow passing through the aperture, with a first portion of the divided airflow contacting the heatsink of the LED assembly and a second portion of the divided air flow contacting an exterior of the driver heatsink.
2. The luminaire of claim 1 , wherein the aperture is in a central region of the LED assembly.
3. The luminaire of claim 1 , wherein the aperture is offset from a central region of the LED assembly.
4. The luminaire of claim 1 , wherein the driver heatsink is thermally isolated from the LED heat sink.
5. The luminaire of claim 1 , wherein the driver heatsink interior includes a recess in which one or more capacitors of the circuit board assembly are positioned.
6. The luminaire of claim 5 , wherein the one or more capacitors are located to the circuit board assembly base.
7. The luminaire of claim 1 , wherein the driver assembly comprises an endcap assembly including an endplate having one or more components coupling the LED assembly to the driver assembly.
8. The luminaire of claim 1 , wherein the circuit board assembly comprises a card edge for electrical connection with the LED assembly via a wire harness assembly.
9. The luminaire of claim 1 , wherein the driver assembly further comprises a ground contact fastener coupling the circuit board to the driver heatsink.
10. The luminaire of claim 1 , wherein the LED assembly comprises a plurality of LED boards.
11. The luminaire of claim 10 , wherein the LED boards are arranged to define the aperture.
12. The luminaire of claim 1 further comprising a sensor assembly positioned in the aperture of the LED assembly.
13. The luminaire of claim 12 , wherein the sensor assembly is recessed in the aperture, precluding light from the LED assembly from directly striking the sensor assembly.
14. The luminaire of claim 12 , wherein the sensor assembly is connected directly to the driver assembly.
15. The luminaire of claim 1 , wherein the LED assembly comprises one or more optical components satisfying spacing criterion of 0.7 to 2.0.
16. The luminaire of claim 1 , wherein the LED assembly comprises a monolithic lens array.
17. The luminaire of claim 16 , wherein the monolithic lens array is field interchangeable.
18. The luminaire of claim 1 having a light output of 15,000 to 70,000 lumens at an efficiency of at least 125 lumens per watt.
19. The luminaire of claim 1 , wherein the driver assembly has a thermal resistance of 0.57° C./W to 1° C./W.
20. The luminaire of claim 19 having a color rendering index (CRI) of at least 70 and a correlated color temperature of 4000K.
