Claim Text:
1. A method of manufacturing a phosphor for a light-emitting diode (LED), the method comprising: filling a phosphor frame in which phosphor models are formed in an engraving form with a fluorescent material solution comprising a fluorescent material that converts light provided by the light-emitting diode into white light by changing a wavelength of the light provided by the light-emitting diode, wherein the phosphor models are filled with the fluorescent material solution to the extent that the fluorescent material solution overflows the phosphor models; adjusting a light-emitting-color to reduce a variance among individual model-formed phosphors in the phosphor frame by polishing a top surface of the phosphor frame filled with the fluorescent material solution to a conformable thickness; drying the phosphor frame filled with the fluorescent material solution; and separating each of the model-formed phosphors from the phosphor frame wherein hardness (Durometer Shore D) of the model-formed phosphor separated from the phosphor frame is 25 to 75 after drying the polished phosphor frame; and wherein the hardness of the model-formed phosphor separated from the phosphor frame is controlled by changing an addition ratio (wt %) of the hardner, and wherein a ratio of the phosphor to silicon in the model-formed phosphor is substantially 1:1.
