1. An apparatus comprising:
- a container configured to receive a liquid silicone, and a powdered phosphor, wherein the container has a syringe structure including an outlet disposed at a lower portion thereof, and a mixture of the liquid silicone and the powdered phosphor is discharged into a light emitting diode (LED) package through the outlet;
a silicone supply unit configured to supply the liquid silicone to the container up to a predetermined quantity;
a phosphor supply unit configured to supply the powdered phosphor to the container up to a predetermined quantity; and
a transfer unit configured to transfer the container from the silicone supply unit to the phosphor supply unit, such that the container is sequentially provided with the liquid silicone and the powdered phosphor, and the outlet is prevented from being clogged by the powdered phosphor,wherein the silicone supply unit and the phosphor supply unit have different structures from each other.
