Abstract

A recessed lighting fixture comprises a generally annular body having a central cavity in the form of a partially spherical socket. There is a lighting support member having a partially spherical exterior portion which is closely fitted within the partially spherical socket of the annular body. The lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body and the partially spherical exterior portion of the lighting support member is substantially restricted. There may be a light source mounted to the lighting support member adjacent a bottom thereof. The light source may be a light-emitting diode.

Claims

1. A recessed lighting fixture comprising:

a generally annular body having a central cavity in the form of a partially spherical socket;

a lighting support member having a partially spherical exterior portion fitted within the partially spherical socket of the annular body; and

an O-ring sealingly disposed between the partially spherical exterior portion of the lighting support member and the partially spherical socket of the annular body, whereby the lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body, the partially spherical exterior portion of the lighting support member, and a ceiling is substantially restricted.

2. The recessed lighting fixture of claim 1, wherein the lighting support member has a bottom and a light source is mounted to the lighting support member adjacent the bottom thereof.

3. The recessed lighting fixture of claim 2, wherein the light source is a light-emitting diode.

4. The recessed lighting fixture of claim 1, wherein the O-ring is made of silicone.

5. The recessed lighting fixture of claim 1, wherein the annular body has a bottom, the lighting fixture having an outwardly extending annular flange adjacent the bottom of the annular body for fitting over an exterior surface of the ceiling.

6. The recessed lighting fixture of claim 1, wherein the annular body has a top, the lighting fixture including spring-loaded members connected to the annular body adjacent to the top thereof and extending outwardly therefrom, the spring-loaded members being configured to resiliently contact an upper, interior surface of the ceiling.

7. The recessed lighting fixture of claim 6, wherein each of the spring-loaded members includes a coil spring mounted on the lighting support member and an outwardly extending arm connected to the coil spring.

8. The recessed lighting fixture of claim 1, wherein the lighting support member has a top, the lighting fixture including a heat sink mounted on the lighting support member adjacent the top thereof.

12. The recessed lighting fixture of claim 1, wherein the O-ring is made of silicone.

9. A recessed lighting fixture comprising:

a generally annular body having a central cavity in the form of a partially spherical socket;

a lighting support member having a partially spherical exterior portion fitted within the partially spherical socket of the annular body; and

an O-ring sealingly disposed between the partially spherical exterior portion of the lighting support member and the partially spherical socket of the annular body, whereby the lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body, the partially spherical exterior portion of the lighting support member, and a ceiling is substantially restricted;

a power supply module; and

an electrical conductor connecting the lighting fixture to the power supply module.

10. The recessed lighting assembly of claim 9, wherein the lighting support member has a bottom and a light source is mounted to the lighting support member adjacent the bottom thereof.

11. The recessed lighting assembly of claim 10, wherein the light source is a light-emitting diode.

13. The recessed lighting fixture of claim 9, wherein the annular body has a bottom, the lighting fixture having an outwardly extending annular flange adjacent the bottom of the annular body for fitting over an exterior surface of the ceiling.

14. The recessed lighting fixture of claim 9, wherein the annular body has a top, the lighting fixture including spring-loaded members connected to the annular body adjacent to the top thereof and extending outwardly therefrom, the spring-loaded members being configured to resiliently contact an upper, interior surface of the ceiling.

15. The recessed lighting assembly of claim 14, wherein each of the spring-loaded members includes a coil spring mounted on the lighting support member and an outwardly extending arm connected to the coil spring.

16. The recessed lighting assembly of claim 9, wherein the lighting support member has a top, the lighting fixture including a heat sink mounted on the lighting support member adjacent the top thereof.
