1. A lamp comprising:
- a housing having wall portions defining a cavity and an opening;
a transparent lens cover coupled to the wall portions and covering the opening;
a light source located within the cavity;
at least one thermoelectric device located within one of the wall portions, the thermoelectric device having a first side oriented substantially towards the cavity and a second side oriented substantially away from the cavity, whereby the first side will transfer heat generated by the light source to the second side;
whereby the light source further comprises a lamp and a first heat exchanger, the lamp coupled to the first heat exchanger; and
a second heat exchanger coupled to the first side of the thermoelectric device, the second heat exchanger oriented substantially towards the first heat exchanger, thereby providing greater heat transfer between the first and second heat exchangers.

Abstract
A lamp system having a housing, wall portions defining a cavity and an opening. A light source, generally an LED, is located within the cavity and at least one thermoelectric device is disposed in one of the wall portions. The thermoelectric device has a first side oriented towards the cavity and the second side oriented away from the cavity. When in operation, the thermoelectric device will transfer heat from inside the cavity, via the first side of the thermoelectric device, to the second side of the thermoelectric device.
