Abstract
A method for fabricating a light emitting diode (LED) device includes the steps of forming (or providing) a plurality of LED dice, forming a plurality of wavelength conversions layers, and then evaluating at least one electromagnetic radiation emission characteristic of each LED die and at least one color characteristic of each wavelength conversion layer. The method also includes the steps of comparing the evaluated characteristic of each LED die and the evaluated characteristic of each wavelength conversion layer to a database, selecting a selected LED die and a selected wavelength conversion layer based on the evaluating and comparing steps, and then attaching the selected wavelength conversion layer to the selected LED die.
