Patent ID: 8038497

Claim:
A method of fabricating a light emitting device (LED), the method comprising: measuring emission characteristics for a plurality of LED chips configured to emit light of a first color; sorting the plurality of LED chips based on the measured emission characteristics to provide a plurality of groups respectively including ones of the plurality of LED chips having similar measured emission characteristics; for each of the plurality of groups, selecting a respective light conversion material configured to absorb at least some of the light of the first color and responsively emit light of a second color based on the measured emission characteristics of the ones of the plurality of LED chips included therein and a desired color point; for each of the plurality of groups, responsive to selection of the respective light conversion material, determining a respective thickness of the respective light conversion material based on the measured emission characteristics of the ones of the plurality of LED chips included therein; and for each of the plurality of groups, depositing the respective light conversion material to the respective determined thickness on the ones of the LED chips included therein to provide a plurality of packaged LEDs comprising the plurality of LED chips and respectively configured to emit light having the desired color point.
