Zusammenfassung:Light-emitting diode (LED) packages and more particularly LED packages with selectively placed light-altering materials and related methods are disclosed. Selectively placed light-altering materials are provided that are arranged along peripheral edges of LED chips and along portions of underlying submounts. By covering peripheral edges of LED chips without covering entire submount surfaces, light-altering materials may be provided in reduced amounts while still redirecting laterally propagating light from the LED chips. Methods of selectively placing light-altering materials include selectively dispensing one or more droplets on submount portions that are proximate LED chip edges and allowing the one or more droplets to wick about the LED chip edges and portions of the submount before curing in place.
