Abstract
An apparatus and method of manufacturing a light emitting diode (LED) device, and more particularly, an apparatus and method of manufacturing an LED device by dispensing a fluorescent solution prepared by mixing a fluorescent material with a liquid synthetic resin, onto an LED chip. An apparatus and method of manufacturing an LED device, whereby an appropriate amount of fluorescent solution simultaneously in consideration of several factors, such as characteristics of an LED chip and viscosity of the fluorescent solution may be dispensed onto the LED chip, is provided. An apparatus and method of manufacturing an LED device, whereby an appropriate amount of fluorescent solution may be calculated actively in consideration of viscosity of the fluorescent solution, a change in characteristics of an LED chip, or the like, and the appropriate amount of fluorescent solution may be dispensed onto the LED chip, is provided.
