Abstract

A recessed luminaire includes a trim, a junction box, and a light source socket. The trim includes a trim body, a flange, and a cover section. The flange extends out from the trim body at an opening of the trim. The junction box and the light source socket are attached to the trim. The light source socket is positioned inside a cavity of the trim. The light source socket may be attached to a cover section of the trim or to a bracket that is attached to the trim.

First claim

What is claimed is:

1. A recessed luminaire, comprising:
a trim comprising a trim body, a flange, and a cover section, wherein the flange extends out from the trim body at an opening of the trim and wherein the trim body and the flange are formed as a single integrated component, wherein when the trim is installed in a ceiling, the flange extends outwardly below a ceiling surface and remains visible from below the ceiling surface,
wherein the cover section is opposite the opening, and wherein a sidewall of the trim body is located above the opening and below the cover section and wherein the trim body and cover section form a cavity of the trim;
a junction box attached to the trim and located adjacent the sidewall of the trim body outside the cavity of the trim, wherein the junction box includes a first wire routing opening located below the cover section, and wherein a second wire routing opening is formed in a substantially flat portion of the sidewall of the trim body located below the cover section, wherein the first wire routing opening and the second wire routing opening are aligned such that a wire routed between the first wire routing opening and the second wire routing opening is routed below the cover section; and
a light source socket, wherein the light source socket is attached to the trim, and wherein the light source socket is positioned inside the cavity of the trim.

2. The recessed luminaire of claim 1 , further comprising a thermal protector positioned in the cavity of the trim to disconnect electrical power from the light source socket when a temperature in the cavity of the trim exceeds a threshold temperature.

3. The recessed luminaire of claim 1 , wherein the cover section includes at least one guide for the attachment of the junction box to the trim.

4. The recessed luminaire of claim 1 , wherein the trim body comprises a cylindrical section and a baffle section and wherein the baffle section extends down outwardly from the cylindrical section.

5. The recessed luminaire of claim 4 , wherein the flange extends out from the baffle section.

6. The recessed luminaire of claim 4 , wherein the junction box is attached to the cover section and to the cylindrical section.

7. The recessed luminaire of claim 4 , wherein the junction box is directly attached to the cylindrical section.

8. The recessed luminaire of claim 1 , wherein a heat shield material is located between the light source socket and the cover section.

9. The recessed luminaire of claim 1 , further comprising a bracket positioned in the cavity of the trim and attached to the trim, wherein the light source socket is attached to the bracket.

10. The recessed luminaire of claim 1 , wherein the cavity of the trim does not mechanically attach additional trims.

11. A recessed luminaire, comprising:
a trim comprising a trim body, a flange, and a cover section, wherein the flange extends out from the trim body at an opening of the trim and wherein the trim body and the flange are formed as a single integrated component, wherein when the trim is installed in a ceiling, the flange extends outwardly below a ceiling surface and remains visible from below the ceiling surface,
wherein a sidewall of the trim body is located above the opening and below the cover section and wherein the trim body and cover section form a cavity of the trim;
a junction box attached to the trim and located adjacent the sidewall of the trim body outside the cavity of the trim with a first wire routing opening located below the cover section, wherein a second wire routing opening is formed in a substantially flat portion of a sidewall of the trim body located below the cover section, wherein the first wire routing opening and the second wire routing opening are aligned such that a wire routed between the cavity of the trim and a cavity of the junction box is routed below the cover section; and
a light source socket,
wherein the light source socket is attached to the trim, and wherein light source socket is positioned inside the cavity of the trim.

12. The recessed luminaire of claim 11 , further comprising a thermal protector positioned in the cavity of the trim to disconnect electrical power from the light source socket when a temperature in the cavity of the trim exceeds a threshold temperature.

13. The recessed luminaire of claim 11 , wherein the cover section encloses the cavity of the trim at an end of the trim opposite from the opening of the trim, and wherein an attachment tab extends from the junction box and is attached to the cover section.

14. The recessed luminaire of claim 11 , wherein the trim body comprises a cylindrical section and a baffle section, and wherein the baffle section extends down outwardly from the cylindrical section.

15. The recessed luminaire of claim 11 , wherein the light source socket is directly attached to the cover section.

16. The recessed luminaire of claim 11 , further comprising a bracket positioned in the cavity of the trim and attached to the trim, wherein the light source socket is attached to the bracket.

17. A recessed luminaire, comprising:
a trim comprising a body, a flange, a trim cap, and a light emitting opening, wherein the body and the flange are formed as a single integrated component, wherein when the trim is installed in a ceiling, the flange extends outwardly below a ceiling surface and remains visible from below the ceiling surface,
and wherein the trim cap encloses the body at an end of the trim opposite from the light emitting opening, wherein a sidewall of the body is located above the opening and below the trim cap and wherein the body and trim cap form a cavity of the trim;
one or more retention devices coupled to an outer surface of the trim;
a light source socket disposed on an inner surface of the trim;
a first aperture in a substantially flat portion of the sidewall below the trim cap; and
a conduit comprising a first end and a second end, the first end adapted to couple to the first aperture located below the trim cap and the second end adapted to couple to a second aperture in a junction box, wherein the conduit routes a wire between a cavity of the trim and a cavity of the junction box such that the wire routed between the cavity of the trim and a cavity of the junction box is routed below the trim cap, and wherein substantially all of the cavity of the junction box is located below the trim cap and outside of the body.

18. The recessed luminaire of claim 17 , wherein the light source socket is configured to receive a light emitting diode light source or a compact fluorescent light source.

19. The recessed luminaire of claim 17 , further comprising a thermal protector directly attached to the trim cover and a bracket positioned in the cavity of the trim and attached to the trim, wherein the light source socket is attached to the bracket and located entirely below the thermal protector.

20. The recessed luminaire of claim 17 , wherein the body is separated from the junction box by the conduit.
