1. An LED based light comprising:
- at least one LED; and
at least one thermoelectric generator having a first side and a second side, wherein the first side is thermally coupled to the at least one LED such that heat generated by the at least one LED is passively conducted to the at least one thermoelectric generator, producing a temperature differential between the first side and second side, wherein the at least one thermoelectric generator is configured to produce electrical energy from the temperature differential.
