Abstract

A retention structure for retaining a recessed lighting fixture behind a ceiling includes an attachment structure that has a first wall and a second wall. The attachment structure is designed to be attached to a housing of a recessed light fixture. The retention structure further includes a screw attached to the first wall of the attachment structure and to the second wall of the attachment structure. The retention structure also includes a pawl attached to the threaded screw. The pawl is rotatable along with the threaded screw. The pawl is also axially movable along the threaded screw between the first wall of the attachment structure and the second wall of the attachment structure.

First claim

What is claimed is:

1. A lighting structure for a recessed lighting fixture, the lighting structure comprising:
a lighting fixture housing having an opening that faces a floor below the lighting fixture housing when the lighting fixture housing is recessed in a ceiling, wherein the opening is at a bottom end of the lighting fixture housing; and
a junction box attached to the lighting fixture housing, wherein a first portion of the junction box proximal to the lighting fixture housing is vertically narrower than a second portion of the junction box distal from the lighting fixture housing, wherein a proximal end of the junction box is attached to the lighting fixture housing at a top end of the lighting fixture housing, wherein the junction box is tapered between a distal end of the junction box and the proximal end of the junction box, and wherein, when the lighting fixture housing is oriented such that the opening faces the floor, a first portion of a bottom wall of the junction box proximal to the lighting fixture housing is elevated relative to a second portion of the bottom wall of the junction box distal to the lighting fixture housing.

2. The lighting structure of claim 1 , wherein the junction box includes a first side wall and a second side wall, wherein a bottom edge of the first side wall is slanted angularly upwards as the first side wall extends towards the lighting fixture housing, and wherein, when the lighting fixture housing is oriented such that the opening of the lighting fixture housing faces the floor, a bottom edge of the second side wall is slanted angularly upwards as the second side wall extends towards the lighting fixture housing.

3. The lighting structure of claim 2 , wherein the junction box includes a back wall, wherein the bottom wall and the back wall extend between the first side wall and the second side wall, and wherein the back wall is at the distal end of the junction box.

4. The lighting structure of claim 3 , wherein a cavity of the junction box is accessible via the back wall.

5. The lighting structure of claim 1 , wherein the proximal end of the junction box is attached to a housing top of the lighting fixture housing.

6. The lighting structure of claim 5 , wherein the lighting fixture housing is cylindrical.

7. The lighting structure of claim 5 wherein the proximal end of the junction box is attached to an attachment area of the housing top, wherein the attachment area is substantially flat.
