Abstract

A wall mounted light fixture includes a surface mount including a rear wall having a plurality of mounting openings, a top wall extending from the rear wall, and a bottom wall extending from the rear wall. The light fixture housing is connected to the surface mount and defines an interior portion. A light emitter is positioned in the interior portion of the housing. A lens is connected to the housing. A sensor assembly including a sensor housing and a sensor module is positioned at least partially in the sensor housing. The sensor assembly is operatively connected to the light emitter and the sensor housing is external to the light fixture housing.

First claim

What is claimed:

1. A wall mounted light fixture comprising:
a surface mount including a rear wall having a plurality of mounting openings, a top wall extending from the rear wall, and a bottom wall extending from the rear wall;
a light fixture housing connected to the surface mount, the light fixture housing defining an interior portion;
a light emitter positioned in the interior portion of the housing;
a lens connected to the housing; and
a sensor assembly including a sensor housing and a sensor module positioned at least partially in the sensor housing,
wherein the sensor assembly is operatively connected to the light emitter and the sensor housing is external to the light fixture housing.

2. The light fixture of claim 1 , wherein the sensor assembly includes a mounting bracket and the sensor module is connected to the mounting bracket.

3. The light fixture of claim 2 , wherein the sensor housing is snap-fit to the mounting bracket.

4. The light fixture of claim 2 , wherein the mounting bracket includes a top wall, and a front wall extending from the top wall, and wherein the sensor module is connected to the front wall.

5. The light fixture of claim 1 , wherein the sensor module includes an ultrasonic sensor.

6. The light fixture of claim 1 , wherein the sensor assembly is connected to the bottom wall of the surface mount.

7. The light fixture of claim 1 , wherein the sensor assembly is positioned below the light fixture housing.

8. The light fixture of claim 1 , wherein the surface mount includes top flange and a bottom flange configured to connect to the light fixture housing.

9. The light fixture of claim 1 , wherein the light fixture housing includes a body member having a first side facing the interior of the housing and a second side facing an exterior of the housing, the first side of the body having a plurality of front connecting features and the second side of the body having a plurality of rear connecting features, and wherein the light emitter is supported by the body member.

10. A light fixture sensor assembly comprising:
a mounting bracket including a top wall having a connecting feature and a front wall extending at an oblique angle from the top wall;
a sensor housing connected to the mounting bracket, wherein the sensor housing includes an outer wall having a sensor opening; and
a sensor module positioned in the housing and having a sensor component positioned in the sensor opening,
wherein the mounting bracket is configured to be connected to the exterior of a light fixture.

11. The light fixture sensor assembly of claim 10 , wherein the mounting bracket includes a tab extending from the front wall opposite the top wall.

12. The light fixture sensor assembly of claim 10 , wherein the connecting feature includes a set of L-shaped slots.

13. The light fixture sensor assembly of claim 10 , wherein the top wall includes a central slot.

14. The light fixture sensor assembly of claim 10 , wherein the top wall includes a V-shaped ear engaging the sensor housing.

15. The light fixture sensor assembly of claim 10 , wherein the front wall extends at an acute angle to the top wall.

16. The light fixture sensor assembly of claim 10 , wherein the sensor module is connected to the mounting bracket.

17. The light fixture sensor assembly of claim 10 , wherein the sensor module includes an ultrasonic sensor.

18. The light fixture sensor assembly of claim 10 , wherein the sensor module includes a receiver and an emitter.

19. The light fixture sensor assembly of claim 10 , wherein the sensor housing is snap-fit to the mounting bracket.

20. The light fixture sensor assembly of claim 10 , wherein the sensor housing includes a cantilevered tab engaging the mounting bracket.
