First Claim
Patent Images
1. An LED lamp apparatus, comprising:
- a light-emitting diode;
a multi-part heat exchanger comprising a first portion and a second portion wherein the first portion of the multi-part heat exchanger is in direct or indirect physical contact with the light-emitting diode;
at least one electrical component configured to drive the light-emitting diode wherein the second portion of the multi-part heat exchanger is in direct or indirect physical contact with the at least one electrical component; and
wherein the first portion of the multi-part heat exchanger is thermally isolated from the second portion of the multi-part heat exchanger such that the light emitting diode and first portion are configured to operate at a first temperature and the at least one electrical component and said second portion are configured to operate at a second temperature, the second temperature being lower than the first temperature.
