LED for plant illumination

A fabrication method for a light emitting diode (LED), including: 1) mounting a LED chip on a substrate; 2) mounting a screen printing template on the LED chip; 3) coating a silicone gel layer over the surface of the screen printing template; 4) printing the phosphor: printing the phosphor over the chip surface via silk screen printing process and recycling the excess phosphor; and 5) removing the screen printing template and baking the phosphor for curing, and coating the cured phosphor over the chip surface. In the packaging method of the present disclosure, the unused phosphor can be recycled because it is not polluted by the screen printing template material.
