  "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.",
  "claims": [
    "1. A lighting structure, comprising: a junction box having a cavity, wherein the junction box comprises a first tab and a second tab that extend outwardly from the junction box; and a mounting plate having an inner section, a perimeter section, and a wireway section extending between the inner section and the perimeter section, the wireway section having a wire opening therethrough and providing a wireway on an opposite side of the mounting plate from the junction box for routing an electrical wire from the cavity to the perimeter section, 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.",
    "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 perimeter section of the mounting plate is outside the junction box.",
    "4. The lighting structure of claim 1, wherein that first tab is on an opposite side of the junction box from the second tab.",
    "5. The lighting structure of claim 4, wherein the slot is under an elevated section that is seamlessly formed in the mounting plate.",
    "6. The lighting structure of claim 1, wherein the mounting plate includes a raised section that is seamlessly formed in the mounting plate, the raised section having an attachment hole for attaching a lighting driver to the mounting plate by a fastener.",
    "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, wherein the junction box comprises a first tab and a second tab that extend outwardly from the junction box; and a mounting plate having an inner section, a perimeter section, and a wireway section extending between the inner section and the perimeter section, the wireway section having a wire opening therethrough and providing a wireway on an opposite side of the mounting plate from the junction box for routing an electrical wire from the cavity to the LED light source, wherein the LED light source is located at the perimeter section on the opposite side of the mounting plate from the junction box, 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.",
    "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 first tab is on an opposite side of the junction box from the second tab and wherein the slot is under an elevated section that is seamlessly formed in 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 comprises mounting tabs extending radially outwardly from the perimeter section, and wherein the mounting plate is attached to the trim ring using fasteners that extend through holes in the mounting tabs.",
    "15. The lighting fixture of claim 11, further comprising a retention structure for retaining the lighting fixture recessed in a ceiling.",
    "16. A lighting fixture, comprising: a light emitting diode (LED) driver; a junction box having a cavity, wherein the junction box comprises a first tab and a second tab that extend outwardly from the junction box and wherein the LED driver is positioned inside the cavity; and a mounting plate having an inner section, a perimeter section, and a wireway section extending between the inner section and the perimeter section, the wireway section having a wire opening therethrough and providing a wireway on an opposite side of the mounting plate from the junction box for routing an electrical wire between the LED driver in the cavity and the perimeter section, 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.",
    "17. The lighting fixture of claim 16, further comprising a light source attached to the perimeter section of the mounting plate on the opposite side of the mounting plate from the junction box.",
    "18. The lighting fixture of claim 16, further comprising a trim ring positioned around the mounting plate, wherein the mounting plate is attached to the trim ring.",
    "19. The lighting fixture of claim 16, wherein the mounting plate includes a raised section that is formed in the mounting plate, the raised section having an attachment hole for attaching the LED driver to the mounting plate.",
    "20. The lighting fixture of claim 16, further comprising a retention structure for retaining the lighting fixture recessed in a ceiling."

  "description_excerpt": "The present disclosure relates generally to lighting fixtures, and more particularly to a lighting structure and junction box assembly of a lighting fixture.\n\nJunction boxes are often used for placement of lighting drivers of lighting fixtures and for making safe wiring connections. Typically, a junction box is separate from a light fixture. For example, the junction box may be structurally unattached to a light fixture, or may be attached to a light fixture by a joining structure (e.g., an arm) extending therebetween. However, in some applications, a structurally separate junction box or a junction box that is attached to a light fixture by a joining structure may be inconvenient and/or undesirable. For example, a space that is available behind a ceiling may be small or otherwise limited. In retrofitting installations, use of an existing junction box or installing a new junction box may be challenging and result in added cost. Further, in cases such as temporary installations (e.g., during building construction phases), use of a separate junction box may add to cost.\n\nThus, in some applications, a solution that avoids use of a structurally separate junction may be desirable.\n\nThe present disclosure relates to a lighting structure and junction box assembly of a lighting fixture. In an example embodiment, 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.",
