White LED light source package

The invention provides a white LED light source package, which comprises a heat sink (8), an insulating substrate (1) bonded on the upper surface of the heat sink (8), an LED chip (2) bonded on the upper surface of the insulating substrate (1), a reflection spotlight cup (3) arranged around the LED chip, an epoxy resin layer (4) fixed on the upper surface of the insulating substrate (1), reflection cups (5) coated at both side surfaces of the epoxy resin layer (4), a fluorescent powder layer (6) coated on the upper surface of the epoxy resin layer (4), and glass (7) covering the upper surface of the fluorescent powder layer (6), wherein a power source is connected on an electrode of the LED chip (2), and the LED chip (2) array is arranged on the upper surface of the insulating substrate, so the emergent light of the white LED light source package is more uniform.
