Patent ID: 8878430

Claim:
A lighting device comprising a light generation unit, which comprises a light emitting diode element having at least one light emitting diode, and a light conversion unit, said light generation unit further comprising a base part, which comprises a thermally conductive material thermally connected with the light emitting diode element, wherein the light conversion unit is separated from the light generation unit and comprises a separate and sealed integral enclosure, which encloses a cavity, and an organic phosphor element arranged within the sealed integral enclosure cavity, said sealed cavity provided with a controlled atmosphere in order to protect the organic phosphor element from degrading over time due to oxygen; wherein light generated by the light emitting diode element of the light generation unit is output through the light conversion unit and thereby converted by the organic phosphor element; wherein the light generation unit comprises a shell which is attached to the light conversion unit and to a portion of the base part extending beyond the light conversion unit, and which forms a space wherein drive electronics are arranged on the base part.
