Abstract
A lighting device comprising a plurality of LEDs; a plurality of optic devices corresponding to the plurality of LEDs; at least one optical separator for substantially preventing the light emitted from one LED from effecting the other LEDs; a thermoelectric device configured to harvest heat generated by the LEDs and convert the harvested heat into electrical energy; and a low temperature material for creating a temperature difference across the thermoelectric device.
