Abstract

A lighting structure includes a junction box that has a cavity, and a mounting plate that has an inner section and a perimeter section. The junction box is attached to the mounting plate, and the mounting plate has a wire opening therethrough for routing an electrical wire from the junction box to a light source. The perimeter section of the mounting place is outside the junction box.

First claim

What is claimed is:

1. A lighting structure, comprising:
a junction box having a cavity, wherein the junction box includes a wall having a notch formed therethrough; and
a mounting plate having an inner section and a perimeter section, wherein the junction box is attached to the mounting plate, the mounting plate having a wire opening therethrough for routing an electrical wire from the junction box to a light source, wherein the perimeter section of the mounting plate is outside the junction box, wherein the mounting plate includes an elevated wireway section providing a wireway for routing the electrical wire between the cavity of the junction box and the perimeter section, wherein a first portion of the elevated wireway section is in the cavity of the junction box, wherein a second portion of the elevated wireway section is external to the cavity of the junction box, and wherein the elevated wireway section extends through the notch and under the wall of the junction box.

2. The lighting structure of claim 1 , wherein the mounting plate comprises tabs extending radially outwardly from the perimeter section of the mounting plate.

3. The lighting structure of claim 1 , wherein the junction box comprises a first tab and a second tab for attaching the junction box to the mounting plate.

4. The lighting structure of claim 3 , wherein the first tab is attached to the mounting plate by a fastener and wherein the second tab is inserted into a slot formed in the mounting plate.

5. The lighting structure of claim 1 , wherein the mounting plate includes a raised section that is seamlessly formed in the mounting plate and having an attachment hole for attaching a lighting driver to the mounting plate by a fastener.

6. The lighting structure of claim 1 , wherein the wire opening of the mounting plate is formed through the elevated wireway section and wherein the junction box is positioned on a side of the mounting plate and the elevated wireway section is elevated on the side of the mounting plate.

7. The lighting structure of claim 6 , wherein the junction box comprises a wire passageway in a wall of the junction box for extending one or more electrical wires into the cavity of the junction box.

8. The lighting structure of claim 1 , wherein the junction box comprises a top cover that is moveable to provide access to the cavity of the junction box.

9. The lighting structure of claim 1 , wherein the junction box comprises a knockout section in a wall of the junction box.

10. The lighting structure of claim 1 , wherein the junction box and the mounting plate are integrally formed as a single structure.

11. A lighting fixture, comprising:
a light emitting diode (LED) light source;
a junction box having a cavity; and
a mounting plate having an inner section and a perimeter section, wherein the junction box is attached to the inner section of the mounting plate on a first side of the mounting plate, wherein the LED light source is attached to the mounting plate on a second side of the mounting plate and at a circumference of the mounting plate, the mounting plate having a wire opening for routing an electrical wire, wherein the perimeter section of the mounting plate is outside the junction box, wherein the mounting plate includes a wireway section seamlessly formed in the mounting plate and providing a wireway for routing the electrical wire between the cavity of the junction box and the LED light source, wherein a first portion of the wireway section is in the cavity of the junction box, and wherein a second portion of the wireway section is external to the cavity of the junction box.

12. The lighting fixture of claim 11 , further comprising a lighting driver positioned in the cavity of the junction box.

13. The lighting fixture of claim 11 , wherein the junction box is positioned on a side of the mounting plate and the wireway section is elevated on the side of the mounting plate.

14. The lighting fixture of claim 11 , further comprising a trim ring positioned around a circumference of the mounting plate, wherein the mounting plate is attached to the trim ring.

15. The lighting fixture of claim 11 , wherein the mounting plate comprises mounting tabs extending radially outwardly from the perimeter section and wherein the mounting plate is attached to a trim ring using fasteners that extend through holes in the mounting tabs.

16. The lighting fixture of claim 11 , further comprising a retention structure for retaining the lighting fixture recessed in a ceiling.

17. A lighting fixture, comprising:
a light emitting diode (LED) driver;
a junction box having a cavity, wherein the driver is positioned inside the cavity; and
a mounting plate having an inner section and a perimeter section, wherein the junction box is attached to the inner section of the mounting plate, the mounting plate having a wire opening for routing an electrical wire, and wherein the perimeter section of the mounting plate is outside the junction box, wherein the mounting plate includes an elevated wireway section seamlessly formed in the mounting plate and providing a wireway for routing the electrical wire between the LED driver in the cavity of the junction box and the perimeter section, wherein a first portion of the elevated wireway section is in the cavity of the junction box, and wherein a second portion of the elevated wireway section is external to the cavity of the junction box.

18. The lighting fixture of claim 17 , further comprising a light source attached to the perimeter section of the mounting plate, wherein the driver and the light source are on opposite sides of the mounting plate.

19. The lighting fixture of claim 17 , further comprising a trim ring positioned around the mounting plate, wherein the mounting plate is attached to the trim ring.

20. The lighting fixture of claim 17 , wherein the mounting plate includes a raised section that is formed in the mounting plate and having an attachment hole for attaching a lighting driver to the mounting plate by a fastener.

21. The lighting fixture of claim 17 , further comprising a retention structure for retaining the lighting fixture recessed in a ceiling.
