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; andwherein 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. 2. The apparatus of claim 1, wherein the first portion of the multi-part heat exchanger is at least partially thermally-isolated from the second portion of the multi-part heat exchanger by a physical distance. 3. The apparatus of claim 2, wherein thermal isolation is achieved by an air gap between the said first portion and the second portion of the multi-part heat exchanger. 4. The apparatus of claim 2, wherein thermal isolation is achieved by a solid thermal insulation material between the first portion and the second portion of the multi-part heat exchanger. 5. The apparatus of claim 1, wherein the at least one electrical component to drive the light-emitting diode includes a capacitor. 6. The apparatus of claim 1, wherein the at least one electrical component configured to drive the light-emitting diode comprises a resistor. 7. The apparatus of claim 1, wherein the LED lamp is in the form factor of at least one of, an MR-16 lamp, an A series lamp, a PS series lamp, a B series lamp, a C series lamp, a CA series lamp, an RP series lamp, an S series lamp, an F series lamp, an R series lamp, an MR series lamp, a BR series lamp, a G series lamp, a T series lamp, a BT series lamp, an E series lamp, an ED series lamp, an AR series lamp, and a PAR series lamp. 8. An illumination device, comprising: a light source having at least one 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 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; andwherein 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. 9. The illumination device of claim 8, wherein the illumination device is at least one of, an MR-16 lamp, an A series lamp, a PS series lamp, a B series lamp, a C series lamp, a CA series lamp, an RP series lamp, an S series lamp, an F series lamp, an R series lamp, an MR series lamp, a BR series lamp, a G series lamp, a T series lamp, a BT series lamp, an E series lamp, an ED series lamp, an AR series lamp, and a PAR series lamp. 10. The device of claim 8, wherein the first portion of the multi-part heat exchanger is at least partially thermally-isolated from the second portion of the multi-part heat exchanger by a physical distance. 11. The device of claim 10, wherein thermal isolation is achieved by an air gap between the said first portion and the second portion of the multi-part heat exchanger. 12. The device of claim 10, wherein thermal isolation is achieved by a solid thermal insulation material between the first portion and the second portion of the multi-part heat exchanger. 13. The device of claim 8, wherein the at least one electrical component to drive the light-emitting diode includes a capacitor. 14. The device of claim 8, wherein the at least one electrical component configured to drive the light-emitting diode comprises a resistor. 15. The device of claim 1, wherein the first and second portions conform to standard lamp form factor. 16. The device of claim 1, wherein said first portion comprises a first heat sink and said second portion comprises a second heat sink, wherein that the light emitting diode and first sink are configured to operate at a first temperature and the at least one electrical component and said second sink are configured to operate at a second temperature, the second temperature being lower than the first temperature.
