Abstract

A light fixture includes one or more light modules and a sensor module coupled to a housing of the light fixture. The sensor module includes an extension arm and a sensor unit that is rotatably coupled to one end of the extension arm. The other end of the extension arm that is opposite to the end coupled to the sensor unit is pivotably coupled to the housing of the light fixture to pivotably rotate the sensor module between a first position and a second position based on a mounting of the light fixture. Further, the sensor unit is adjustable independent of the extension arm.

First claim

What is claimed is:

1. A light fixture comprising:
a housing;
one or more light modules coupled to the housing;
a sensor module coupled to the housing, the sensor module comprising:
an extension arm pivotably coupled to the housing at a first end of the extension arm such that the sensor module is adjustable between a first position and a second position,
wherein the extension arm comprises a top member and a bottom member that are coupled to each other to form a cavity to hold a friction plate,
wherein the friction plate is coupled to a sensor unit, and
wherein the top member of the extension arm comprises a slot along which the friction plate is configured to slide such that the sensor unit is rotatable based on a motion of the friction plate along the slot.

2. The light fixture of claim 1 , wherein the first position is a retracted position where the sensor module is disposed within a recess in the housing and the second position is an extended position where the sensor module is extended out and away from the recess in the housing.

3. The light fixture of claim 1 , wherein the sensor unit is rotatable independent of the extension arm.

4. The light fixture of claim 1 , wherein the sensor module is in the second position when the light fixture is ceiling mounted.

5. The light fixture of claim 1 , wherein the sensor module is in the first position when the light fixture is wall mounted.

6. A light fixture comprising:
a housing comprising a recess portion;
one or more light modules coupled to the housing;
a sensor module pivotably coupled to the housing such that the sensor module pivots between a first position where the sensor module is disposed within the recess and a second position where the sensor module is extended out and away from the recess,
wherein the sensor module comprises:
an extension arm comprising a top member and a bottom member that are coupled to each other to form a cavity to hold a friction plate; and
a sensor unit rotatably coupled to the friction plate at a distal end of the extension arm,
wherein the top member of the extension arm comprises a slot along which the friction plate is configured to slide such that the sensor unit is rotatable based on a motion of the friction plate along the slot.

7. The light fixture of claim 6 , wherein the sensor unit comprises a motion sensor.

8. The light fixture of claim 6 , wherein the sensor module is in the first position when the light fixture is wall mounted.

9. The light fixture of claim 6 , wherein the sensor module is in the second position when the light fixture is ceiling mounted.

10. A motion sensor module comprising:
an extension arm adapted to be rotatably coupled to a housing of a light fixture at a first end; and
a motion sensor unit rotatably coupled to a second end of the extension arm that is opposite to the first end,
wherein the extension arm pivots between a first position where the motion sensor module is disposed within a recess of the housing and a second position where the motion sensor module is extended out and away from the recess of the housing,
wherein the extension arm comprises a top member and a bottom member that are coupled to each other to form a cavity to hold the friction plate,
wherein the friction plate is coupled to the motion sensor unit; and
wherein the top member of the extension arm comprises a slot along which the friction plate is configured to slide such that the motion sensor unit is rotatable based on a motion of the friction plate along the slot.

11. The motion sensor module of claim 10 , wherein the motion sensor module is in the first position when the light fixture is wall mounted.

12. The motion sensor module of claim 10 , wherein the motion sensor module is in the second position when the light fixture is ceiling mounted.

13. The motion sensor module of claim 10 :
wherein the motion sensor unit comprises a motion sensor housing configured to house a motion sensor and electrical components associated with the motion sensor, and
wherein the motion sensor housing comprises one or more control knobs to adjust at least one sensor characteristic of the motion sensor.

14. The motion sensor module of claim 13 , wherein the motion sensor housing is coupled to the extension arm via the friction plate and the slot such that the motion sensor unit is rotatable independent of a position of the extension arm.

15. The motion sensor module of claim 10 , wherein the recess of the housing is configured to house the extension arm and at least a portion of the motion sensor unit.
