Abstract
A light-emitting diode luminaire includes at least one light-emitting diode and at least one thermoelectric generator in contact with a portion of the luminaire. The at least one thermoelectric generator is operable to harvest energy from heat dissipated by the at least one light-emitting diode. An energy management module is operable to receive energy harvested by the at least one thermoelectric generator.
Claims20
A light-emitting diode luminaire, comprising:
- at least one light-emitting diode;
- a heatsink operable to provide a path for heat dissipation away from the at least one light-emitting diode;
- at least one thermoelectric generator in contact with a portion of the luminaire, the thermoelectric generator being operable to harvest energy from heat dissipated by the at least one light-emitting diode;
- and
- an energy management module operable to receive energy harvested by the at least one thermoelectric generator.
