Abstract

A bracket can connect a luminaire to a junction box or other housing or structure, for example at a ceiling. The bracket can be mounted to the junction box using one or more fasteners. The bracket can comprise two tabs, and the luminaire can comprise two corresponding slots. Alternatively, the bracket can comprise two slots, and the luminaire two corresponding tabs. The luminaire can be attached to the bracket by positioning the luminaire so that the two tabs are inserted into the two slots and rotating the luminaire so the slots and tabs engage and lock.

First claim

What is claimed is:

1. A system for mounting a luminaire, the system comprising:
a bracket configured for partial insertion in a first aperture of a ceiling and attachment to a junction box separately mounted above the ceiling, the bracket comprising:
a center portion dimensioned for insertion in the separately mounted junction box via the first aperture;
an outer portion dimensioned to obstruct insertion in the first aperture;
one or more second apertures in the center portion arranged for fastening the bracket to the junction box when the center portion is inserted in the separately mounted junction box via the first aperture; and
one or more first fasteners disposed on the outer portion of the bracket; and

a luminaire comprising:
a power system sized for insertion in the first aperture;
a rim sized larger than the first aperture, the rim comprising a first side for facing the ceiling and a second side opposite the first side; and
and one or more second fasteners disposed on the first side of the rim,

wherein the one or more first fasteners and the one or more second fasteners fasten together to fasten the luminaire to the bracket.

2. The system of claim 1 , wherein the center portion of the bracket comprises a receptacle for the power system of the luminaire, and
wherein the power system comprises an LED driver.

3. The system of claim 2 , wherein the receptacle is sized for insertion in the junction box.

4. The system of claim 1 , wherein the one or more first fasteners and the one or more second fasteners fasten together in a slot-and-tab connection.

5. The system of claim 1 , wherein the one or more first fasteners and the one or more second fasteners fasten together by rotation of the luminaire relative to the bracket.

6. The system of claim 1 , wherein the one or more first fasteners and the one or more second fasteners are hidden from view when the one or more first fasteners and the one or more second fasteners are fastened together.

7. The system of claim 1 , wherein the outer portion comprises two bracket arms that are separated from one another by the center portion,
wherein the one or more first fasteners comprise two tabs disposed at respective ends of the two bracket arms,
wherein each of the two tabs comprises a first portion and a second portion,
wherein the one or more second fasteners comprise two slots, each sized to receive one of the two tabs,
wherein each slot has a perimeter that comprises a notch and a protrusion, and
wherein when the two slots receive the two tabs, the notch receives the first portion and the protrusion engages the second portion.

8. The system of claim 1 , wherein each of the one or more first fasteners comprises a slot and each of the one or more second fasteners comprises a tab.

9. The system of claim 1 , wherein each of the one or more second fasteners comprises a slot and each of the one or more first fasteners comprises a tab.

10. The system of claim 1 , wherein the outer portion of the bracket comprises a disk.

11. A system comprising:
a mounting bracket comprising a center portion and at least two tabs, each disposed radially with respect to the center portion and separated by a distance; and
at least two slots that are disposed on a back side of a luminaire and separated by the distance, each slot comprising a perimeter that comprises a notch and a protrusion,
wherein the center portion is sized for insertion in a junction box mounted above an aperture in a ceiling,
wherein the mounting bracket comprises two arms, each arm comprising a member extending between the center portion and a respective one of the at least two tabs, and
wherein the mounting bracket is configured so that when the center portion is disposed in the junction box mounted above the aperture in the ceiling, each arm is disposed below the ceiling and extends along and substantially parallel to a lower surface of the ceiling.

12. The system of claim 11 , wherein the at least two slots are oriented to engage the at least two tabs using the notch and the protrusion when the luminaire is rotated relative to the mounting bracket.

13. The system of claim 11 , wherein each tab comprises a first portion and a second portion, and
wherein each protrusion engages the first portion and each notch engages the second portion when the tabs are inserted in the slots and the luminaire is rotated relative to the mounting bracket.

14. The system of claim 11 ,
wherein each tab is oriented perpendicular to the member.

15. The system of claim 11 , wherein the mounting bracket further comprises a plurality of apertures that are arranged for attaching the mounting bracket to the junction box using a plurality of fasteners.

16. A system comprising:
a mounting bracket comprising a center portion and at least two slots, each slot disposed radially with respect to the center portion and separated by a distance, each slot comprising a perimeter that comprises a notch and a protrusion; and
at least two tabs that are disposed on a back side of a luminaire and separated by the distance,
wherein the center portion is sized for insertion in a junction box mounted above an aperture in a ceiling,
wherein the mounting bracket comprises two arms, each arm comprising a flat member extending between the center portion and a respective one of the at least two slots, and
wherein the mounting bracket is configured so that when the center portion is disposed in the junction box mounted above the aperture in the ceiling, each arm is disposed below the ceiling and extends along and substantially parallel to a lower surface of the ceiling.

17. The system of claim 16 , wherein the at least two slots are oriented to engage the at least two tabs using the notch and the protrusion when the luminaire is rotated relative to the mounting bracket.

18. The system of claim 16 , wherein each tab comprises a first portion and a second portion, and
wherein each protrusion engages the first portion and each notch engages the second portion when the tabs are inserted in the slots and the luminaire is rotated relative to the mounting bracket.

19. The system of claim 16 , wherein the mounting bracket further comprises a plurality of apertures that are arranged for attaching the mounting bracket to the junction box using a plurality of fasteners.
