Abstract

A recessed lighting fixture includes a housing, a baffle, a trim ring, a cover, and at least one attachment element. The housing includes an inner wall and side walls extending to an open outer end. The baffle is secured to the housing by at least one fastening element and includes a reflector wall extending through the outer end of the housing. The trim ring extends radially outward from the reflector wall beyond the outer end of the housing and defines a central opening. The cover includes a light transmitting panel and an attachment ring extending around an outer periphery of the light transmitting panel, with the attachment ring being sized and shaped to cover a circumference of the trim ring. The at least one attachment element secures the attachment ring to the trim ring, such that an air seal is effected between the attachment ring and the trim ring.

First claim

The invention claimed is:

1. A recessed lighting fixture comprising:
a housing having an inner wall and side walls extending to an open outer end;
a baffle secured to the housing by at least one fastening element and including a reflector wall extending through the outer end of the housing;
a trim ring extending radially outward from the reflector wall beyond the outer end of the housing, the trim ring defining a central opening;
a cover, comprising a light transmitting panel and an attachment ring extending around an outer periphery of the light transmitting panel, the attachment ring being sized and shaped to cover a circumference of the trim ring; and
at least one attachment element securing the attachment ring to the trim ring, such that an air seal is effected between the attachment ring and the trim ring,
wherein the at least one attachment element comprises a magnetic element, and
wherein the magnetic element comprises a magnetic ring surrounding the central opening in the trim ring.

2. The recessed lighting fixture of claim 1 , wherein the air seal is effected by the at least one attachment element.

3. The recessed lighting fixture of claim 1 , further comprising a seal ring compressed between the trim ring and the attachment ring to effect the air seal.

4. The recessed lighting fixture of claim 1 , further comprising a compressible trim ring seal assembled with an inner surface of the trim ring and configured to effect an air seal between the trim ring and a surface of an external structure when the recessed lighting fixture is installed in an opening in the external structure.

5. The recessed lighting fixture of claim 4 , wherein the trim ring seal is affixed to the inner surface of the trim ring by an adhesive backing disposed on the trim ring seal.

6. The recessed lighting fixture of claim 1 , wherein the attachment ring includes an outer periphery extending radially outward of the trim ring, the fixture further including a compressible attachment ring seal assembled with the outer periphery of the attachment ring and configured to effect an air seal between the attachment ring and a surface of an external structure when the recessed lighting fixture is installed in an opening in the external structure.

7. The recessed lighting fixture of claim 1 , wherein the attachment ring is sized and shaped to substantially entirely cover the trim ring.

8. A method of providing an enhanced air seal over a central opening of a recessed lighting fixture including a housing installed in an opening in an external structure and having an inner wall and side walls extending to an open outer end, a baffle secured to the housing by at least one fastening element and including a reflector wall extending through the outer end of the housing, and a trim ring extending radially outward from the reflector wall beyond the outer end of the housing, the trim ring defining a central opening, the method comprising:
providing a cover including a light transmitting panel and an attachment ring extending around an outer periphery of the light transmitting panel;
securing the attachment ring to the trim ring such that the attachment ring covers a circumference of the trim ring; and
effecting an air seal between the trim ring and the attachment ring,
wherein securing the attachment ring to the trim ring comprises affixing a magnetic element to one of the trim ring and the attachment ring, wherein the other of the trim ring and the attachment ring comprises a ferromagnetic material, and
wherein the magnetic element comprises a magnetic ring surrounding the central opening in the trim ring.

9. The method of claim 8 , wherein the air seal is effected by the at least one attachment element.

10. The method of claim 8 , further comprising compressing a seal ring between the trim ring and the attachment ring to effect the air seal.

11. The method of claim 8 , further comprising compressing a trim ring seal between an inner surface of the trim ring and an outer surface of the external structure to effect an air seal between the trim ring and the outer surface of the external structure.

12. The method of claim 11 , further comprising affixing the trim ring seal to the inner surface of the trim ring by an adhesive backing disposed on the trim ring seal.

13. The method of claim 8 , further comprising compressing an attachment ring seal between an inner surface of an outer periphery of the attachment ring and an outer surface of the external structure to effect an air seal between the attachment ring and the outer surface of the external structure, the outer periphery of the attachment ring extending radially outward of the trim ring.

14. The method of claim 8 , wherein securing the attachment ring to the trim ring such that the attachment ring covers a circumference of the trim ring comprises substantially entirely covering the trim ring.

15. A kit for providing an enhanced air seal over a central opening of a recessed lighting fixture including a housing installed in an opening in an external structure and having an inner wall and side walls extending to an open outer end, a baffle secured to the housing by at least one fastening element and including a reflector wall extending through the outer end of the housing, and a trim ring extending radially outward from the reflector wall beyond the outer end of the housing, the trim ring defining a central opening, the kit comprising:
a cover including a light transmitting panel and an attachment ring extending around an outer periphery of the light transmitting panel, the attachment ring including a ferromagnetic material disposed around a circumference of the attachment ring;
a magnetic ring sized to align with the circumference of the attachment ring, the magnetic ring including an adhesive backing for affixing the magnetic ring to an outer surface of the trim ring of the recessed lighting fixture, the magnetic ring being configured to effect an air seal between the cover and the trim ring when the magnetic ring is affixed to the outer surface of the trim ring and the attachment ring is magnetically attached to the magnetic ring.

16. The kit of claim 15 , further comprising a compressible trim ring seal compressible trim ring seal including an adhesive backing for affixing the trim ring seal to an inner surface of the trim ring, the trim ring seal being configured to effect an air seal between the trim ring and a surface of an external structure when the recessed lighting fixture is installed in an opening in the external structure.

17. A recessed lighting fixture comprising:
a housing having an inner wall and side walls extending to an open outer end;
a baffle secured to the housing by at least one fastening element and including a reflector wall extending through the outer end of the housing;
a trim ring extending radially outward from the reflector wall beyond the outer end of the housing, the trim ring defining a central opening;
a cover, comprising a light transmitting panel and an attachment ring extending around an outer periphery of the light transmitting panel, the attachment ring being sized and shaped to cover a circumference of the trim ring; and
at least one attachment element securing the attachment ring to the trim ring, such that an air seal is effected between the attachment ring and the trim ring,
wherein the at least one attachment element comprises a magnetic element, and
wherein the magnetic element is affixed to the trim ring by an adhesive backing disposed on the magnetic element, and the attachment ring comprises a ferromagneti
