Abstract

An LED lamp includes a LED assembly comprising at least one LED operable to emit light when energized through an electrical path. A heat sink structure is thermally coupled to the LED assembly for dissipating heat to the ambient environment. An aromatic structure is thermally coupled to the heat sink structure such that the aromatic structure is heated by the heat dissipated from the heat sink.

First claim

The invention claimed is:

1. An LED lamp comprising:
a LED assembly comprising at least one LED operable to emit ight when energized through an electrical path;
a heat sink structure thermally coupled to the LED assembly, the heat sink structure comprising a heat dissipating portion that is exposed to an exterior of the lamp for dissipating heat to the ambient environment;
an aromatic structure comprising a plastic infused with an aromatic material that is mounted on the exterior of the lamp and is positioned at least partially over the heat dissipating portion and is in thermally coupled to the heat sink structure such that the aromatic structure is heated by the heat dissipated from the heat sink structure to facilitate the emission of a scent from the aromatic structure.

2. The LED lamp of claim 1 , wherein the aromatic structure is removably mounted to the lamp.

3. The LED lamp of claim 1 , wherein the aromatic structure is removably attached to the lamp using at least one of a snap-fit connector, a friction fit, an adjustable strap, a screw connection and a spring clip.

4. The LED lamp of claim 1 , wherein the aromatic structure comprises apertures allowing the heat sink structure access to the ambient environment.

5. The LED lamp of claim 1 , wherein the aromatic structure is permanently attached to the heat sink structure.

6. The LED lamp of claim 1 , wherein the aromatic structure is part of the heat sink structure.

7. The LED lamp of claim 1 , wherein the aromatic structure is part of a housing.

8. An LED lamp comprising:
a LED assembly comprising at least one LED operable to emit light when energized through an electrical path;
a heat sink structure thermally coupled to the LED assembly comprising a heat dissipating portion having an exterior surface that is exposed to an exterior of the lamp for dissipating heat to the ambient environment;
an aromatic structure mounted on the exterior of the lamp and having an interior surface, the interior surface contacting the exterior surface of the heat dissipating portion such that the aromatic structure is heated by the heat dissipated from the heat sink structure to facilitate the emission of a scent from the aromatic structure.

9. The lamp of claim 8 , wherein the aromatic structure comprises a plastic infused with an aromatic material.

10. The LED lamp of claim 8 , wherein the aromatic structure is removably mounted to the lamp.

11. The LED lamp of claim 10 , wherein the aromatic structure is removably attached to the lamp using at least one of a snap-fit connector, a friction fit, an adjustable strap, a screw connection and a spring clip.

12. The LED lamp of claim 8 , wherein the aromatic structure comprises apertures allowing the heat sink structure access to the ambient environment.

13. The LED lamp of claim 8 , wherein the aromatic structure is permanently attached to the lamp.

14. The LED lamp of claim 8 , wherein the aromatic structure is molded to the heat sink structure.

15. The LED lamp of claim 8 , wherein the aromatic structure comprises a trim ring.

16. An aromatic structure for an LED lamp comprising:
a shell configured to fit at least partially over an exposed portion of a heat sink of a LED lamp, the shell comprising a plastic infused with an aromatic material.

17. The LED lamp of claim 16 , wherein the shell comprises at least one of a snap-fit connector, an adjustable strap, a screw connection and an elastic strap.

18. An aromatic structure for an LED lamp comprising:
an annular trim ring configured to attach to a housing of a LED lamp such that it covers an exposed portion of the housing, the trim ring comprising a plastic infused with an aromatic material.

19. The LED lamp of claim 18 , wherein the trim ring comprises at least one of a spring clip, screw and deformable connector.
