Patent ID: 8247247

Claim:
A method for manufacturing an LED module, comprising steps of: providing a heat conductive plate and an LED die, the heat conductive plate defining a concave groove therein; forming an electrically insulating layer on the heat conductive plate; forming an electrode circuit layer on the electrically insulating layer around the concave groove; plating one metal layer on a bottom of the concave groove of the heat conductive plate, and plating another metal layer on the LED die; eutectically bonding the metal layer of the heat conducting plate and the metal layer of the LED die together to form into an eutectic layer; forming electrodes on the LED die, and connecting the electrodes with the electrode circuit layer; and encapsulating the LED die in the concave groove; wherein a Si plate is selected as the heat conductive plate, the electrically insulating layer is formed on the heat conductive plate by one of the following methods: oxidating method, nitridizing method, a combination method of oxidating and nitridazing, and a spin coating method.
