Abstract:
1. A method for fabricating a semiconductor light emitting device, the method comprising: providing a first string of light emitting diodes (“LED”) that comprises a first LED that has a first recipient luminophoric medium that comprises a first luminescent material that emits light comprising a peak wavelength within the green color range in response to radiation emitted by the first LED; providing a second string of LEDs that comprises a second LED that has a second recipient luminophoric medium that comprises a second luminescent material that emits light comprising a peak wavelength within the yellow color range in response to radiation emitted by the second LED; providing a third string of LEDs that comprises a third LED that emits light comprising a distinct spectral peak within the red color range or the orange color range; selecting the LEDs included in the first string and in the second string so that when the first string and second string are operated at pre-selected drive current levels the combined light output of the first string and the second string is on a line on the 1931 CIE Chromaticity Diagram that is defined by the color point for the combined output of the third sting and a pre-selected color point for the light output by the semiconductor light emitting device.
