METHOD FOR FABRICATING LIGHT EMITTING DIODE (LED) DEVICES HAVING OUTPUT WITH SELECTED CHARACTERISTICS

摘要

A method for fabricating a LED device includes the steps of forming (or providing) a plurality of LED dice (10), forming a plurality of wavelength conversions layers (22), and then evaluating at least one electromagnetic radiation emission characteristic of each LED die (10) and at least one color characteristic of each wavelength conversion layer (22). The method also includes the steps of comparing the evaluated characteristic of each LED die (10) and the evaluated characteristic of each wavelength conversion layer (22) to a database, selecting a LED die (10) and one or more wavelength conversion layers (22) based on the evaluating and comparing steps, and then attaching the selected wavelength conversion layer (22) to the selected LED die (10).
