Abstract

The invention relates to a thermal management system for a lamp. The system comprises a lamp socket that comprises a socket body. The thermal assembly is in thermal communication with the socket body to form a thermal circuit between the lamp and the thermal assembly for dissipating heat generated by the lamp.

Claims (23)

1. A lighting assembly for use with an induction lamp having an engagement end, the lighting assembly comprising:

a mount body configured to receive the engagement end of the lamp, wherein the mount body defines at least one bore extending at least partially therethrough the mount body; and

a thermal assembly, wherein a proximal portion of the thermal assembly is mounted therein at least a portion of the at least one bore of the mount body and is in thermal communication with the mount body to form a thermal circuit between the lamp and the thermal assembly, and wherein the thermal assembly comprises a variable conductance heat pipe.

2. The lighting assembly of claim 1 , wherein the thermal assembly is configured to dissipate heat from the lamp to the surrounding environment.

3. The lighting assembly of claim 1 , wherein the thermal assembly is configured to selectively dissipate heat from the lamp to the surrounding environment.

4. The lighting assembly of claim 1 , wherein at least a portion ofthe proximal portion of the thermal assembly extends therefrom the at least one bore.

5. The lighting assembly of claim 1 , wherein a proximal portion of the thermal assembly is integrally mounted therein a portion of the mount body.

6. The lighting assembly of claim 1 , wherein at least a portion of the proximal portion of the thermal assembly is connected to an exterior portion of the mount body.

7. The lighting assembly of claim 1 , further comprising a lamp housing, and wherein the mount body is disposed within the lamp housing.

8. The lighting assembly of claim 7 , wherein a portion of the thermal assembly is in thermal communication with a portion of the lamp housing.

9. The lighting assembly of claim 8 , wherein the lamp housing is comprised of a thermally conductive material.

10. The lighting assembly of claims 8 or 9 , wherein the external surface of the lamp housing comprises a plurality of fins.

11. The lighting assembly of claim 10 , wherein a distal portion of the thermal assembly is embedded within at least a portion of the plurality of fins.

12. The lighting assembly of claim 10 , wherein a distal portion of the thermal assembly is connected to at least a portion of the plurality of fins.

13. The lighting assembly of claim 11 further comprising a dissipation member located proximate the housing, wherein the thermal assembly is in thermal communication with the dissipation member.

14. A lighting assembly for use with an induction lamp having an engagement end, the lighting assembly comprising:

a mount body configured to receive the engagement end of the lamp; and

a heat pipe, wherein at least a portion of a proximal portion of the heat pipe is embedded within the mount body and is configured to be in thermal communication with the mount body to form a thermal circuit between the lamp and the heat pipe, and wherein the heat pipe is configured to selectively dissipate heat from the lamp to the surrounding environment.

15. The lighting assembly of claim 14 , wherein the heat pipe is configured to dissipate heat from the lamp to the surrounding environment.

16. The lighting assembly of claim 14 , wherein the heat pipe is a variable conductance heat pipe.

17. The lighting assembly of claim 14 , further comprising a lamp housing, wherein the mount body is disposed within the lamp housing, and wherein a portion of the heat pipe is in thermal communication with a portion of the lamp housing.

18. The lighting assembly of claim 17 , wherein the external surface of the lamp housing comprises a plurality of fins, and wherein a distal portion of the heat pipe is embedded within at least a portion of the plurality of fins.

19. The lighting assembly of claim 18 , wherein a distal portion of the heat pipe is connected to at least a portion of the plurality of fins.
