Abstract

Sensor housings, modules, and luminaires comprising the same are provided. The sensor housings and modules set forth herein have improved heat sinking abilities for dissipating heat from a sensor while simultaneously facilitating thermal isolation of the sensor. Briefly, a sensor housing described herein comprises a cavity for housing a sensor and a heat sink. The heat sink is configured to dissipate heat from the sensor housing and thermally isolate the sensor housing from other heat generating components, such as other portions of a luminaire.

First claim

The invention claimed is:

1. A luminaire comprising:
an electronic sensor having a sensor housing in thermal communication with a heat sink, the heat sink comprising a plurality of heat dissipation structures radially arranged over an outer wall of the sensor housing.

2. The luminaire of claim 1 , where the luminaire further comprises a luminaire housing.

3. The luminaire of claim 2 , where the luminaire housing includes the sensor housing.

4. The luminaire of claim 1 , where the electronic sensor comprises drive circuitry, and
a sensing device in electrical communication with the drive circuitry.

5. The luminaire of claim 4 where the drive circuitry comprises at least any one of a processor, a controller, a memory element, a wireless antenna, and combinations thereof.

6. The luminaire of claim 1 where the heat sink is configured to thermally insulate the electronic sensor.

7. The luminaire of claim 1 where the electronic sensor comprises at least any one of an image sensor, a light sensor, a motion sensor, a temperature sensor, a magnetic field sensor, a gravity sensor, a humidity sensor, a moisture sensor, a vibration sensor, a pressure sensor, an electrical field sensor, a noise sensor, an environmental sensor, a directional sensor, a position sensor, a velocity sensor, an airflow sensor, a chemical sensor, a carbon dioxide sensor, an oxygen sensor, and combinations thereof.

8. The luminaire of claim 1 where the electronic sensor comprises a wireless interface configured to wirelessly communicate data from the electronic sensor.

9. The luminaire of claim 8 , wherein the interface comprises one or more antennae within the sensor housing.

10. The luminaire of claim 1 where the sensor housing includes at least one wall defining a cavity for accepting the electronic sensor.

11. The luminaire of claim 10 , wherein the heat sink forms a portion of the outer wall.

12. The luminaire of claim 10 , wherein the outer wall comprises an aperture.

13. The luminaire of claim 12 , wherein the aperture is configured to receive optics of a sensor.

14. The luminaire of claim 1 , wherein the heat sink is coupled to a surface of the outer wall.

15. The luminaire of claim 1 , wherein the plurality of heat dissipation structures comprises fins.

16. The luminaire of claim 1 further comprising thermally insulating material in the sensor housing.

17. The luminaire of claim 1 , wherein the sensor is an image sensor, and the sensor housing is integrated with the luminaire.

18. The luminaire of claim 1 , wherein the heat sink forms one or more portions of the sensor housing.
