Abstract
The invention relates to a method of forming a phosphor film and a method of manufacturing an LED package incorporating the same. The method of forming a phosphor film includes mixing phosphor and light-transmitting beads in an aqueous solvent such that the nano-sized light-transmitting beads having a first charge are adsorbed onto surfaces of phosphor particles having a second charge. The method also includes coating a phosphor mixture obtained from the mixing step on an area where the phosphor film is to be formed, and drying the coated phosphor mixture to form the phosphor film. The invention further provides a method of manufacturing an LED package incorporating the method of forming the phosphor film.
