Abstract

Devices and methods for externally accessing and adjusting a lighting fixture optic and adjusting a lighting fixture enclosure on its base. Embodiments provide a lighting fixture enclosure with an opening at the top that both receives a removable screw for securing the top and, when the screw is removed, allows insertion of a tool to rotate a reflector and thereby adjust the rotational direction of the light. Such a reflector may be movably coupled to an inside surface of the fixture top while being secured to a bracket. A tool inserted through the opening at the top of the fixture may engage an aperture in the bracket such that as the tool is rotated, the bracket and secured reflector also rotate. Embodiments also involve a base support mounted within the bottom end of a lighting fixture enclosure and a base having apertures for receiving anchor bolts to mount the base to a surface and configured to be received within the base support such that the lighting fixture enclosure is rotationally adjustable about the base.

Claims

1. A lighting system comprising a lighting fixture enclosure comprising:

a body;

a fixture top coupled to the body to form the enclosure within which a light source is mounted, wherein the fixture top comprises an opening that receives a fastening device;

a reflector positioned inside the fixture top and having a rotational orientation;

wherein the reflector rotational orientation is externally adjustable.

2. The lighting system of claim 1, wherein the reflector rotational orientation is externally adjustable through the opening in the fixture top.

3. The lighting system of claim 2, further comprising a tool, wherein the reflector rotational orientation is externally adjustable by inserting the tool through the opening.

4. The lighting system of claim 1, further comprising a bracket provided on the reflector and having an aperture that is substantially coaxial with the opening.

5. The lighting system of claim 4, further comprising a tool adapted to be inserted through the opening, engage the bracket aperture, and rotate the bracket to adjust the rotational orientation of the reflector.

6. A method of adjusting a lighting fixture comprising:

providing a lighting fixture comprising (a) a body, (b) a fixture top coupled to the body to form an enclosure within which a light source is mounted, wherein the fixture top comprises an opening that receives a fastening device, and (c) a reflector positioned inside the fixture top and having a rotational orientation;

inserting a tool through the opening in the fixture top; and

rotating the tool to change the rotational orientation of the reflector.

7. The method of claim 6, wherein providing a lighting fixture provides a lighting fixture that further comprises a bracket provided on the reflector and having an aperture that is substantially coaxial with the opening.

8. The method of claim 7, further comprising:

engaging the bracket aperture with the inserted tool, and

rotating the tool to rotate the bracket and change the rotational orientation of the reflector.

9. A lighting system comprising:

a lighting fixture enclosure having a base support located therein; and

a base mountable to an underlying surface and shaped to engage the base support of the lighting fixture enclosure such that the lighting fixture enclosure is rotatable about the base.

10. The system of claim 9, further comprising a plurality of set screws for securing the base to the base support.

11. The system of claim 9, wherein the base support is welded inside the bottom end of the lighting fixture enclosure.

12. The system of claim 9, wherein the base has a shape that is substantially circular.

13. The system of claim 9, wherein the lighting fixture enclosure is rotatable three-hundred sixty degrees about the base.

14. The system of claim 9, further comprising anchor bolts that are received within openings in the base for mounting the base to the surface.

15. A method of installing a surface-mounted lighting fixture comprising:

providing a base for mounting to a surface;

securing the base to a surface;

positioning a light over the base;

rotating the light relative to the base; and

securing the light to the base.

16. The method of claim 15, wherein the light comprises a light source within a lighting fixture enclosure having a base support.

17. The method of claim 16, wherein positioned the light over the base comprises engaging the base support of the lighting fixture enclosure such that the lighting fixture enclosure is rotatable about the base.

18. The method of claim 17, wherein securing the light to the base comprises tightening a plurality of set screws from the base support into a substantially circular frame of the base.
