Abstract
An LED package structure includes a base, an LED chip disposed on the base, at least one metal wire, a phosphor sheet, and an encapsulation resin disposed in the base and encapsulating the LED chip, the metal wire, and the phosphor sheet. The LED chip has at least one electrode thereon. The metal wire has an apex and a loop height being defined by the apex. The metal wire is electrically connected to the electrode and the base. The phosphor sheet includes a B-stage resin and a plurality of phosphor powders mixed therewith. The phosphor sheet is adhered to the LED chip by the B-stage resin capable of viscosity and covers the top surface, the side surface, and the electrode of the LED chip. A thickness of the phosphor sheet is smaller than the loop height, and the apex of the metal wire is exposed from the phosphor sheet.
