Abstract

A lighting assembly has a light fixture with a light source and heatsink thermally coupled to the light source. The light source has a light engine with light emitting diodes. A lens is mounted to the light fixture over the light source. The lens is a clear or translucent material. A removable trim is mountable to the light fixture. The removable trim has a flange, recessed portion, and mounting rim. The recessed portion has a depth to reduce glare. The removable trim is formed using a stamping or die casting process. The flange has thermally conductive properties. The removable trim is a metal, thermally conductive plastic, or thermally conductive carbon fiber composite material. A screw is used to mount the removable trim to the light fixture. The light fixture and removable trim are mounted to a recessed can housing using a clip or spring.

Claims

1. A lighting assembly, comprising:

a light fixture having a light source and heatsink thermally coupled to the light source;

a removable trim mountable to the light fixture, the removable trim having a flange with thermally conductive properties around a perimeter of the trim; and

an enclosure for mounting to the light fixture and removable trim.

2. The lighting assembly of claim 1, wherein the removable trim includes a metal, thermally conductive plastic, or thermally conductive carbon fiber composite material.

3. The lighting assembly of claim 1, wherein the removable trim further includes a recessed portion and rim.

4. The lighting assembly of claim 1, further including a screw for mounting the removable trim to the light fixture.

5. The lighting assembly of claim 1, further including a clip or spring for mounting the light fixture and removable trim to the enclosure or ceiling panel.

6. The lighting assembly of claim 1, wherein the light source includes a light engine having a plurality of light emitting diodes.

7. The lighting assembly of claim 1, including a lens mounted to the light fixture over the light source, the lens including a clear or translucent material.

8. A lighting assembly, comprising:

a light fixture having a light source and heatsink thermally coupled to the light source; and

a removable trim mountable to the light fixture, the removable trim having a flange, recessed portion, and rim, the flange having thermally conductive properties.

9. The lighting assembly of claim 8, further including an enclosure for mounting to the light fixture and removable trim.

10. The lighting assembly of claim 8, further including a clip or spring for mounting the light fixture and removable trim to an enclosure or ceiling panel.

11. The lighting assembly of claim 8, wherein the removable trim includes a metal, thermally conductive plastic, or thermally conductive carbon fiber composite material.

12. The lighting assembly of claim 8, further including a screw for mounting the removable trim to the light fixture.

13. The lighting assembly of claim 8, wherein the light source includes a light engine having a plurality of light emitting diodes.

14. The lighting assembly of claim 8, including a lens mounted to the light fixture over the light source, the lens including a clear or translucent material.

15. A removable trim mountable to a light fixture, comprising:

a flange having thermally conductive properties;

a rim; and

a recessed portion disposed between the flange and rim.

16. The removable trim of claim 15, wherein the flange includes a metal, thermally conductive plastic or thermally conductive carbon fiber composite material.

17. The removable trim of claim 15, further including a screw for mounting the removable trim to the light fixture.

18. A method of making a lighting assembly, comprising:

providing a light fixture having a light source;

mounting a heatsink to the light fixture in thermal communication with the light source; and

forming a removable trim mountable to the light fixture, the removable trim having a flange, recessed portion, and rim, the flange having thermally conductive properties.

19. The method of claim 18, further including providing an enclosure for mounting to the light fixture and removable trim.

20. The method of claim 18, further including providing a clip or spring for mounting the light fixture and removable trim to an enclosure or ceiling panel.

21. The method of claim 18, wherein the removable trim includes a metal, thermally conductive plastic, or thermally conductive carbon fiber composite material.

22. The method of claim 18, further including providing a screw for mounting the removable trim to the light fixture.

23. The method of claim 18, wherein the light source includes a light engine having a plurality of light emitting diodes.

24. The method of claim 18, including mounting a lens to the light fixture over the light source, the lens including a clear or translucent material.

25. The method of claim 18, further including forming the removable trim using a stamping, molding, injection molding, or die casting process.
