Abstract
A light energy harvesting apparatus includes an optical element, at least one LED, and a power storage device. The optical element is configured to receive at least one incoming light beam and disperse the at least one incoming light beam into a light spectrum, the light spectrum being defined by a plurality of spectral light beams. Each LED of the at least one LEDs is positioned to receive one of the plurality of spectral light beams and output an electrical power signal therefrom.
Claims20
A light energy harvesting apparatus, comprising:
- (a) an optical element configured to receive at least one incoming light beam and disperse the at least one incoming light beam into a light spectrum, wherein the light spectrum is defined by a plurality of spectral light beams wherein the plurality of spectral light beams comprises different wavelength;
- and
- (b) at least one LED, wherein each LED of the at least one LEDs is positioned to receive one of the plurality of spectral light beams and output an electrical power signal therefrom.
A method of harvesting light energy, comprising:
- (a) receiving incoming light beams with a collimating optical element;
- (b) dispersing collimated light beams into a plurality of spectral light beams using an optical element;
- and (c) converting optical energy in each spectral light beam into electrical energy using LEDs positioned to receive respective spectral light beams.
