Adjustable mounting system for a luminaire
A luminaire comprises a light fixture that includes a housing. The housing includes a light emitting diode (LED) light source and a back wall that has a first surface shape. The luminaire further comprises a mounting system that includes a tie rod that has a first end that includes a plurality of teeth. The mounting system also includes a mounting plate rotatably coupled to the tie rod. The mounting plate is coupled to the back wall of the housing. The mounting plate has a second surface shape, where the first surface shape and the second surface shape are substantially the same.
1. A trunnion mounting system for a light fixture, the system comprising:
a surface mounting bracket having a first arm and a second arm;
a first adjustment bracket; and
a second adjustment bracket, wherein the first adjustment bracket is rotatably coupled to the first arm of the surface mounting bracket and wherein the second adjustment bracket is rotatably coupled to the second arm of the surface mounting bracket.
2. The trunnion mounting system of claim 1 , further comprising a mounting plate rotatable with respect to the surface mounting bracket, wherein the first adjustment bracket is coupled to and extends from the mounting plate and wherein the second adjustment bracket is coupled to and extends from the mounting plate.
3. The trunnion mounting system of claim 2 , wherein the mounting plate is rotatable with respect to the surface mounting bracket by being coupled to the first adjustment bracket and the second adjustment bracket.
4. The trunnion mounting system of claim 2 , wherein the mounting plate includes one or more elongated protrusions extending out from a front surface of the mounting plate and wherein each elongated protrusion is sized and shaped to fit into a corresponding elongated slot aperture in a back wall of a light fixture housing.
5. The trunnion mounting system of claim 2 , wherein the mounting plate includes screw bosses for attaching the mounting plate to a light fixture housing.
6. The trunnion mounting system of claim 1 , wherein the first adjustment bracket includes an arcuate slot aperture.
7. The trunnion mounting system of claim 6 , wherein the arcuate slot aperture spans an arc of approximately between 90-270 degrees.
8. The trunnion mounting system of claim 6 , further comprising a first coupling device extending through the arcuate slot aperture, wherein the coupling device is loosened to rotate the mounting plate with respect to the surface mounting bracket and wherein the coupling device is tightened to prevent the mounting plate from rotating with respect to the surface mounting bracket.
9. The trunnion mounting system of claim 6 , wherein the second adjustment bracket includes a second arcuate slot aperture.
10. The trunnion mounting system of claim 1 , wherein the first adjustment bracket includes indicator marks for indicating an amount of rotation of the first adjustment bracket with respect to the surface mounting bracket.
11. The trunnion mounting system of claim 1 , wherein the first adjustment bracket is rotatably coupled to the first arm of the surface mounting bracket at a first pivot point by a first coupling device and wherein the second adjustment bracket is rotatably coupled to the second arm of the surface mounting bracket at a second pivot point by a second coupling device.
12. A luminaire, comprising:
a light fixture comprising a housing, the housing comprising a light emitting diode (LED) light source; and
a trunnion mounting system attached to the housing, the trunnion mounting system comprising:
a surface mounting bracket having a first arm and a second arm;
a first adjustment bracket; and
a second adjustment bracket, wherein the first adjustment bracket is rotatably coupled to the first arm of the surface mounting bracket, wherein the second adjustment bracket is rotatably coupled to the second arm of the surface mounting bracket, and wherein the housing is rotatable along with the first adjustment bracket and the second adjustment bracket.
13. The luminaire of claim 12 , wherein the trunnion mounting system further comprises a mounting plate rotatable with respect to the surface mounting bracket, wherein the first adjustment bracket is coupled to and extends from the mounting plate and wherein the second adjustment bracket is coupled to and extends from the mounting plate.
14. The luminaire of claim 13 , wherein the mounting plate is rotatable with respect to the surface mounting bracket by being coupled to the first adjustment bracket and the second adjustment bracket.
15. The luminaire of claim 13 , wherein the mounting plate includes one or more elongated protrusions extending out from a front surface of the mounting plate and wherein each elongated protrusion fits into a corresponding elongated slot aperture in a back wall of the housing.
16. The luminaire of claim 13 , wherein the mounting plate includes screw bosses used to attach the mounting plate to the housing.
17. The luminaire of claim 12 , wherein the first adjustment bracket includes an arcuate slot aperture.
18. The luminaire of claim 17 , wherein the arcuate slot aperture spans an arc of approximately between 90-270 degrees.
19. The luminaire of claim 17 , wherein the trunnion mounting system further comprises a first coupling device extending through the arcuate slot aperture, wherein the coupling device is loosened to rotate the mounting plate with respect to the surface mounting bracket and wherein the coupling device is tightened to prevent the mounting plate from rotating with respect to the surface mounting bracket.
20. The luminaire of claim 17 , wherein the second adjustment bracket includes a second arcuate slot aperture.
