Abstract
A light emitting apparatus is fabricated by measuring light output of a semiconductor light emitting device, and selectively applying luminous material to the light emitting device based on the measured output of the light emitting device. An amount of luminous material, different compositions of luminous material and/or different doping levels of luminous material may be selectively applied based on the measured output of the light emitting device.
