Abstract

A lighting assembly includes a light fixture adapted to be disposed in relation to an opening defined in a surface of a structure such that a lamp may be installed in the light fixture through the opening of the structure. A thermal insulation barrier surrounds the light fixture, is positioned in close proximity of the opening of the structure and constructed so as to entrap heat from the opening of the structure. A trim has an outer surface, configured to substantially enclose the opening, consists of at least one fireproof material, and is adapted to engage the light fixture so that the outer surface is disposed in proximity to the opening of the structure and forms a continuous surface with the structure.

Claims (23)

1. A lighting assembly comprising:

a light fixture adapted to be disposed adjacent to an opening defined in a surface of a structure, wherein the light fixture is configured to accept a lamp installed through the opening;

a thermal insulation barrier surrounding the light fixture, positioned in close proximity of the opening of the structure and constructed so as to entrap heat received through the opening of the structure; and

a trim having an outer surface configured to substantially enclose the opening, the trim comprising at least one fireproof material and being adapted to engage the light fixture so that the outer surface is disposed in proximity to the opening of the structure and forms a continuous surface with the structure.

2. A lighting assembly as in claim 1 , wherein the thermal insulation baffler is integrally attached to the light fixture.

3. The lighting assembly as in claim 1 , wherein the thermal insulation baffler is formed in the general shape of a cylinder.

4. The lighting assembly as in claim 1 , wherein the thermal insulation baffler is generally formed in the shape of rectangle.

5. The lighting assembly as in claim 1 , wherein the thermal insulation barrier comprises an insulating material suitable for continuous use at temperatures at or below about 1080 degrees F. with an “R-value” greater than 2.2 per inch of thickness, and being constructed in a manner to inhibit heat from transferring via an aperture of the light fixture through the lighting assembly to an area above the surface of the structure.

6. The lighting assembly as in claim 1 , wherein the trim further comprises at least one component which substantially encloses an aperture of the light fixture and an outer portion of the trim which covers a gap between the light fixture and the structure.

7. The lighting assembly as in claim 1 , wherein at least a portion of the trim is adapted to removeably engage the trim to the light fixture.

8. The lighting assembly as in claim 1 , further comprising a housing having an internal surface and the thermal insulation baffler has at least one end disposed in proximity to the internal surface of the housing.

9. The lighting assembly as in claim 8 , wherein the at least one end of the thermal insulation baffler follows a contour of the internal surface of the housing.

10. The lighting assembly as in claim 1 , further comprising a housing having an external surface and the thermal insulation barrier has at least one end disposed in proximity to the external surface of the housing.

11. The lighting assembly as in claim 10 , wherein the at least one end of the thermal insulation barrier follows a contour of the external surface of the housing.

12. The light assembly as in claim 1 , wherein the trim further comprises thermal insulation disposed between the light fixture and the trim to inhibit heat from transferring via the trim through the lighting assembly to an area above the surface of the structure.

13. The light assembly as in claim 12 , wherein the thermal insulation is adapted to cover at least a portion of the trim.

14. A thermal insulation barrier integral to a lighting fixture of a lighting assembly, the light fixture having an aperture and being adapted to be disposed adjacent to an opening defined in a surface of a structure, wherein the light fixture is configured to accept a lamp installed through the opening, the thermal insulation barrier forming a jacket around a housing of the light fixture and comprising an insulating material suitable for continuous use at temperatures at or below about 1080 degrees F. with an “R-value” greater than 2.2 per inch of thickness, and

constructed in a manner to inhibit heat from transferring via the aperture of the light fixture through the lighting assembly to an area above the surface of the structure.

15. A trim for a lighting assembly, the trim adapted to mate with a light fixture of the light assembly, the light fixture being adapted to be disposed adjacent to an opening defined in a surface of a structure, wherein the light fixture is configured to accept a lamp installed through the opening, the trim comprising an outer surface, configured to substantially enclose the opening, comprising at least one fireproof material, and being adapted to engage the light fixture so that the outer surface is disposed in proximity to the opening of the structure and forms a continuous surface with the structure, the trim further comprising a gasket adapted to cover a portion of the trim so as to provide a seal between the trim and the surface of the structure while maintaining the continuous surface between the trim and the structure.

16. The trim as in claim 15 , further comprising a thermal insulation baffler disposed between the light fixture and the trim to inhibit heat from transferring via the trim through the lighting assembly to an area above the surface of the structure.

17. The trim as in claim 16 , wherein the thermal insulation barrier is adapted to cover at least a portion of the trim.

18. The trim as in claim 15 , wherein the light fixture comprises a housing having an internal surface and the thermal insulation has at least one end disposed in proximity to the internal surface of the housing.

19. The trim as in claim 18 , wherein the at least one end of the thermal insulation follows a contour of the internal surface of the housing.
