Abstract:
A method of manufacturing an LED lamp is disclosed. The method includes admixing an uncured curable liquid resin and a phosphor, dispensing the uncured admixture on an LED chip, centrifuging the chip and the admixture to disperse the phosphor particles in the uncured resin, and curing the resin while the phosphor particles remain distributed.
