Patent ID: 7344952

Claim:
A method of fabricating a light emitting diode (LED) comprising: providing a plurality of groups of LEDs, all LEDs in a single group generating substantially a same peak wavelength of light, different groups of LEDs producing different ranges of peak wavelengths determined by testing; mounting a plurality of LEDs of a single particular group onto a submount, such that all LEDs mounted on the submount generate substantially the same peak wavelength of light; providing a plurality of different wavelength-conversion sheets, each sheet comprising a phosphor combined with a flexible encapsulate material, each sheet having a different phosphor conversion characteristic; selecting a particular one of the wavelength-conversion sheets for applying over the single particular group of LEDs on the submount; energizing one or more LEDs on the submount; detecting an emitted color generated by the combination of the energized one or more LEDs in the single particular group of LEDs and the particular wavelength-conversion sheet to ensure the emitted color meets a predetermined color; and encapsulating LEDs from the single particular group mounted on the submount with the particular wavelength-conversion sheet if the emitted color meets the predetermined color.
