Abstract

An illustrative mounting arm for a light fixture provides multiple tilt angles based on the selected orientation of components of the mounting arm. The mounting arm includes a first and second arm portion, each having opposite ends oriented at different relative angles to provide the multiple tilt angles for the light. A support end arm or second arm portion connects directly or indirectly to a wall or other support structure. An intermediate or first arm portion couples between the second arm portion and a mounting pad portion of the light fixture. Each of the first and second arm portions are rotatable in orientation, thus changing the orientation of the angle ends, each combination of possible arm portion orientations displacing the light fixture and therefore the illumination pattern at a different elevation angle relative to the support structure.

Claims

1. A mounting arm for mounting a light fixture to a support structure in a plurality of tilt positions, comprising:

a mounting pad defined by the light fixture;

a first arm portion defining a first arm first end and a first arm second end, the first arm first end coupled with the mounting pad;

a second arm portion defining a second arm first end and a second arm second end, the second arm first end coupled with the first arm second end, the second arm second end coupled with a support structure;

at least one of the first arm and second arm rotatable between a first rotational position and a second rotational position; and

wherein changing the orientation of one of the first arm and second arm, from the first to the second rotational position tilts the light fixture from a first to a second of the plurality of tilt positions.

2. The mounting arm of claim 1, wherein rotational orientation of the first arm relative to the second arm provide at least the following plurality of tilt positions of the light fixture:

3. The mounting arm of claim 1, wherein the relative rotational orientations of the first arm, second arm, and light fixture provide at least the following plurality of tilt positions of the light fixture:

4. The mounting arm of claim 1, wherein a first arm first end plane is defined by the first arm first end and a first arm second end plane is defined the first arm second end, the first arm first end plane being non-parallel to the first arm second end plane.

5. The mounting arm of claim 1, wherein a second arm first end plane is defined by the second arm first end and a second arm second end plane is defined by the second arm second end, the second arm first end plane being non-parallel to the second arm second end plane.

6. The mounting arm of claim 1, further comprising:

a longitudinal arm axis defined between a center of the mounting pad and a center of the second end of the second arm portion; and

wherein changing the orientation of at least one of the first arm and the second arm between the first position and the second position rotates the respective arm about 180 degrees about around the longitudinal arm axis.

7. The mounting arm of claim 6, wherein the coupled mounting pad and first arm and the first arm and second arm are each releasable.

8. The mounting arm of claim 6, further comprising a lens defining a lens plane;

and

wherein the mounting pad forms a mounting plane, and the lens plane and mounting second plane are non-orthogonal.

9. The mounting arm of claim 8, wherein the first end of the first arm defines a first arm first end plane which is oriented relative to the longitudinal axis of the first arm such that coupling of the mounting pad to the first arm first end plane positions the longitudinal axis perpendicular relative to the normal vector of the first plane of the lens.

10. The mounting arm of claim 6, wherein:

the first arm first end defines a first arm first end plane and the first arm second end defines a first arm second end plane, the first arm first end plane being non-parallel to the first arm second end plane;

the second arm first end defines a second arm first end plane and the second arm second end defines a second arm second end plane, the second arm first end plane being non-parallel to the second arm second end plane;

the orientation of each of the first arm and the second arm in one of the first and the second rotational positions provides four orientation combinations, each of the four orientation combinations providing a different relative angular orientation between the first arm first end plane and the second arm second end plane.

11. The mounting arm of claim 10, wherein the first arm second end plane is oriented relative to the longitudinal axis in a complementary angle to the second arm first end plane orientation relative to the longitudinal axis.

12. The mounting arm of claim 1, further comprising an opening defined by each of the mounting pad, first arm first end, first arm second end, second arm first end, and second arm second end, the opening sized to allow passage of electrical wiring therethrough.

13. The mounting arm of claim 1, further comprising a watertight seal between each of the mounting pad and the first arm first end and first arm second end and second arm first end, around the respective openings.

14. The mounting arm of claim 1, further comprising a watertight seal between the second arm second end and the support structure around the opening defined by the second arm second end.

15. The mounting arm of claim 1, further comprising:

a water seal; and

a recess formed by one of the first arm second end and second arm first end, the recess encircling the opening defined by the same end; and

wherein the water seal is positioned at least partially in the recess.

16. The mounting arm of claim 1, further comprising:

a water seal; and

a recess formed by the second arm second end and the recess encircles the opening defined by the second arm second end;

wherein the water seal is positioned at least partially in the recess.
