Patent ID: 8564011

Claim:
A light-emitting diode (LED) package structure, wherein the LED package structure comprises: a housing, which has a top surface forming a cavity, the cavity containing therein a wall to divide the cavity into a light emission section and a voltage regulation section; a first electrode plate, which has a portion exposed inside the light emission section, a portion exposed inside the voltage regulation section, and a portion extending outside the housing; a second electrode plate, which has a portion exposed inside the light emission section, a portion exposed inside the voltage regulation section, and a portion extending outside the housing; a heat-sink metal board, which has a portion exposed inside the light emission section and a portion extending outside the housing, the light-emitting diode being positioned on the heat-sink metal board; a light-emitting diode, which is arranged inside the light emission section, the light-emitting diode having a first electrode electrically connected to the first electrode plate, the light-emitting diode having a second electrode electrically connected to the second electrode plate; and at least one voltage regulation diode, which is arranged inside the voltage regulation section, the voltage regulation diode having a second electrode electrically connected to the first electrode plate, the voltage regulation diode having a first electrode electrically connected to the second electrode plate.
