Abstract:
Methods of forming a light emitting device include selectively forming a wavelength conversion structure on a light emitting element using stereolithography. Selectively forming the wavelength conversion structure may include covering the light emitting element with a photo-curable liquid polymer containing a luminescent material, and exposing the liquid polymer to light for a time sufficient to at least partially cure the liquid polymer. Multiple layers of polymer can be selectively built up to form a wavelength conversion structure having a custom shape on the light emitting element.
