Abstract:
1. A method of manufacturing a light emitting diode (LED) device by dispensing a fluorescent solution prepared by mixing a fluorescent material with a liquid synthetic resin, onto an LED chip, the method comprising: (a) dispensing the fluorescent solution onto a plurality of LED chips, respectively, by using a dispenser; (b) measuring light characteristics of light emitted from the plurality of LED chips by applying power to at least a portion of the plurality of LED chips undergoing the operation (a); (c) calculating a representative value of the light characteristics measured in operation (b); (d) determining an amount of fluorescent solution to be dispensed by the dispenser by using the representative value of the light characteristics calculated in operation (c) and feeding back the amount of fluorescent solution to the dispenser; and (e) dispensing the fluorescent solution having the amount determined in operation (d) onto the plurality of LED chips, respectively, by using the dispenser.
