Systems, Methods and/or Devices for Providing LED Lighting

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.

1 . 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.   
     
     
         2 . The lighting device of  claim 1  wherein the at least one optical separator substantially prevents a change in refractive index of the other lights. 
     
     
         3 . The lighting device of  claim 1  wherein the at least one optical separator substantially prevents a photovoltaic effect on the other lights. 
     
     
         4 . The lighting device of  claim 1  wherein the low temperature material is a phase change material. 
     
     
         5 . The lighting device of  claim 1  wherein the generated electrical energy is used to aid in maintaining the low temperature material at a low temperature. 
     
     
         6 . The lighting device of  claim 1  wherein the generated electrical energy is used to aid in powering at least one additional LED. 
     
     
         7 . The lighting device of  claim 1  wherein the lighting device is supplied with DC voltage. 
     
     
         8 . The lighting device of  claim 1  wherein the lighting device is supplied with AC voltage and at plurality of LEDs are arranged such that about 50% are in a first polarity and about 50% are in a reverse polarity.
