Luminaire retention
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.
1. A lighting structure for a recessed lighting fixture, the lighting structure comprising:
a housing having an opening, the opening including a horizontal slot and a vertical slot, the vertical slot intersecting the horizontal slot; and
a retention structure attached to the housing, the retention structure to retain the lighting structure recessed into a ceiling, wherein the retention structure includes:
a wall segment positioned within the housing;
a tension spring segment positioned outside of the housing, the tension spring segment extending out from a first end portion of the wall segment; and
an end segment having a wide segment and a narrow segment, the narrow segment coupled to a second end portion of the wall segment, wherein the wide segment of the end segment is positioned outside of the housing by extending the wide segment of the end segment through the horizontal slot of the opening of the housing, and wherein the narrow segment of the end segment extends through the vertical slot of the opening of the housing.
2. The lighting structure of claim 1 , wherein the wall segment is positioned against an inner wall of the housing.
3. The lighting structure of claim 1 , wherein the wide segment of the end segment is wider than the vertical slot of the opening of the housing.
4. The lighting structure of claim 1 , wherein the tension spring segment curves down from the first end portion of the wall segment.
5. The lighting structure of claim 1 , wherein a flange of the tension spring segment rests on a back side of the ceiling below the horizontal slot of the opening of the housing.
6. The lighting structure of claim 1 , wherein the housing includes a second opening having a second horizontal slot and a second vertical slot and wherein the second vertical slot intersects the second horizontal slot.
7. The lighting structure of claim 1 , wherein a torsion spring receiver extends out from the wall segment toward a center of the housing.
8. The lighting structure of claim 1 , wherein the narrow segment of the end segment includes a first vertical segment, a horizontal segment, and a second vertical segment, wherein the first vertical segment extends from the second end portion of the wall segment, wherein the horizontal segment extends between the first vertical segment and the second vertical segment, and wherein the second vertical segment is coupled to the wide segment of the end segment.
9. The lighting structure of claim 1 , wherein the horizontal slot of the opening of the housing is above the vertical slot of the opening of the housing when the lighting structure is recessed in a ceiling.
10. A lighting structure for a recessed lighting fixture, the lighting structure comprising:
a housing having an opening, the opening including a horizontal slot and a vertical slot, the vertical slot intersecting the horizontal slot; and
a retention structure to retain the lighting structure recessed into a ceiling, wherein the retention structure includes:
a wall segment to be positioned inside the housing;
a tension spring segment extending out from a first end portion of the wall segment, the tension spring segment to be positioned outside of the housing, wherein the tension spring segment is sized to pass through the horizontal slot of the opening of the housing from within the housing; and
an end segment having a wide segment and a narrow segment, the narrow segment coupled to a second end portion of the wall segment, wherein the wide segment of the end segment is to be positioned outside of the housing by passing the wide segment of the end segment through the horizontal slot of the opening of the housing from within the housing, and wherein the narrow segment of the end segment is sized to extend through the vertical slot of the opening of the housing.
11. The lighting structure of claim 10 , wherein the wall segment is positioned against an inner wall of the housing.
12. The lighting structure of claim 10 , wherein the wide segment of the end segment is wider than the vertical slot of the opening of the housing.
13. The lighting structure of claim 10 , wherein the tension spring segment curves down from the first end portion of the wall segment.
14. The lighting structure of claim 10 , wherein a flange of the tension spring segment is designed to rest on a back side of the ceiling below the horizontal slot of the opening of the housing.
15. The lighting structure of claim 10 , wherein the housing includes a second opening having a second horizontal slot and a second vertical slot and wherein the second vertical slot intersects the second horizontal slot.
16. The lighting structure of claim 10 , wherein a torsion spring receiver extends out from the wall segment toward a center of the housing.
17. The lighting structure of claim 10 , wherein the narrow segment of the end segment includes a first vertical segment, a horizontal segment, and a second vertical segment, wherein the first vertical segment extends from the second end portion of the wall segment, wherein the horizontal segment extends between the first vertical segment and the second vertical segment, and wherein the second vertical segment is coupled to the wide segment of the end segment.
18. The lighting structure of claim 10 , wherein the horizontal slot of the opening of the housing is above the vertical slot of the opening of the housing when the lighting structure is recessed in a ceiling.
