Abstract

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.

First claim

The invention claimed is:

1. A driver assembly comprising:
a driver heat sink comprising an end face; and
an endplate coupled to the end face of the driver heat sink, the endplate including one or more radial structures for supporting a light emitting diode (LED) assembly when the LED assembly is arranged with the driver assembly in a vertical integration, the one or more radial structures being coupled to an LED assembly heat sink,
wherein the LED assembly heatsink is radially spaced from the driver heat sink and is convectively cooled independently from the driver heat sink.

2. The driver assembly of claim 1 , wherein the one or more radial structures comprise at least one of a projection and an arm.

3. The driver assembly of claim 1 , wherein the one or more radial structures comprise a conduit for electrical connections between the driver assembly and the LED assembly.

4. The driver assembly of claim 1 , wherein the endplate couples to the driver heat sink via a gasket, the gasket sealing one end of the heat sink interior.

5. The driver assembly of claim 4 , wherein the heat sink interior comprises potting material.

6. The driver assembly of claim 1 further comprising a circuit board assembly employing a card edge for electrical connection to the LED assembly.

7. The driver assembly of claim 6 , wherein the endplate comprises an aperture for passing the card edge.

8. The driver assembly of claim 1 , wherein the heat sink includes a recess in a wall of the heat sink for housing one or more capacitors of a circuit board assembly.

9. The driver assembly of claim 1 further comprising a circuit board assembly and fastener for coupling the circuit board assembly to the driver heat sink.

10. The driver assembly of claim 9 , wherein the fastener serves as a ground contact between the circuit board assembly and the driver heat sink.

11. The driver assembly of claim 1 further comprising a sensor module coupled to the endplate.

12. The driver assembly of claim 11 , wherein the endplate comprises one or more standoffs for protecting the sensor module.

13. The driver assembly of claim 11 , wherein the sensor module is connected directly to a circuit board assembly through the endplate.

14. The driver assembly of claim 2 , wherein the one or more radial structures comprise an arm including one or more apertures for coupling to the LED assembly via one or more screws or pins.

15. The driver assembly of claim 8 , wherein the driver heat sink further comprises heat dissipation structures assigned solely to cooling the recess.

16. The driver assembly of claim 1 , wherein the one or more radial structures extend to engage the light emitting side of the LED assembly.
