2 . The apparatus for manufacturing a wavelength conversion part of claim 1 , wherein the first temperature adjusting part includes a water cooler, and
the water cooler includes: a circulation pipe at least partially surrounding the dispenser and providing a passage for water to flow, and a temperature adjusting apparatus connected to the circulation pipe to maintain a temperature of the water to be constant.

3 . The apparatus for manufacturing a wavelength conversion part of claim 1 , wherein the first temperature adjusting part includes:
a body; a thermoelement disposed in the body; an air circulation part disposed apart from the body and surrounding the dispenser; a first air passage connected to the body and introducing air into the body; a second air passage connected to the body and moving the air between the body and the air circulation part; and a third air passage connected to the air circulation part and discharging the air from the air circulation part to the outside.

4 . The apparatus for manufacturing a wavelength conversion part of claim 3 , wherein
the body includes an air pump and provides an air circulation path circulating the air inside of the body, and the thermoelement adjusts the temperature of the air in the air circulation path to maintain a constant temperature.

5 . The apparatus for manufacturing a wavelength conversion part of claim 1 , wherein the first temperature adjusting part further includes:
a thermoelement; and a clamp in contact with the dispenser.

6 . The apparatus for manufacturing a wavelength conversion part of claim 5 , wherein the temperature sensor is in contact with the dispenser or the clamp.

7 . The apparatus for manufacturing a wavelength conversion part of claim 1 , wherein the first temperature adjusting part includes an air compression cooler, and
the air compression cooler includes: a compressor including refrigerant gas and compressing the refrigerant gas to provide a heated refrigerant gas; a cooler receiving the heated refrigerant gas from the compressor and cooling the received refrigerant gas to provide a liquefied refrigerant; an expanding valve receiving the liquefied refrigerant from the cooler and cooling the received liquefied refrigerant to provide the refrigerant gas; and a circulation pipe configured to at least partially surround the dispenser and providing a passage inside of the circulation pipe for the refrigerant gas provided from the expanding valve.

8 . The apparatus for manufacturing a wavelength conversion part of claim 1 , wherein the first temperature adjusting part maintains a temperature of the resin in the dispenser within a range of ±5° C. of a predetermined temperature.

9 . The apparatus for manufacturing a wavelength conversion part of claim 8 , wherein the predetermined temperature is in a range of −5° C. to 30° C.

10 . The apparatus for manufacturing a wavelength conversion part of claim 1 , further comprising a first agitator mixing the phosphors in the resin.

11 . The apparatus for manufacturing a wavelength conversion part of claim 10 , further comprising a first temperature maintainer maintaining a temperature of the resin supplied from the first agitator.
