Method of manufacturing light emitting device and phosphor-containing fluid resin dispensing apparatus

Abstract

There is provided a method of manufacturing a light emitting diode (LED) package, including discharging a predetermined discharge amount of a phosphor-containing fluid resin to at least one LED package, and measuring color coordinates of white light emitted from the at least one LED package. The method also includes adjusting a discharge amount of the phosphor-containing fluid resin, based on a deviation between the measured color coordinates and target color coordinates, so as to obtain the target color coordinates. The method further includes discharging the adjusted discharge amount of the phosphor-containing fluid resin to another LED package; and curing the phosphor-containing fluid resin dispensed to the another LED package.
