Patent ID: 7741648

Claim:
A penetrating hole type LED chip package structure using a ceramic material as a substrate, comprising: a ceramic substrate having a main body and a plurality of protrusions separated from each other and extended from a top face of the main body, said ceramic substrate having a plurality of half through holes formed on a lateral side of the main body and each positioned between neighboring protrusions, each protrusion including a penetrating hole offset from said half through holes, a channel extending in an obliquely angled manner through each protrusion from one said penetrating hole to one of said half through holes; a conductive unit having a plurality of first conductive layers, each formed on a respective one of said plurality of protrusions, a plurality of second conductive layers, each formed on an inner surface of a respective one of said plurality of half through holes and a bottom face of the main body, and a plurality of third conductive layers, each filling one said channel, wherein each said third conductive layer is electrically connected between a respective one of said plurality of first conductive layers formed on said plurality of protrusions and one of said plurality of the second conductive layers formed on said inner surface of one of said plurality of half through holes and the bottom face of the main body; a hollow ceramic casing fixed on the top face of the main body to form a receiving space for exposing top faces of the first conductive layer; a plurality of LED chips received in the receiving space, wherein each LED chip has a positive electrode side and a negative electrode side, respectively, said positive and negative electrode sides of said each LED chip being electrically connected with said first conductive layers formed on respective neighboring two of said plurality of protrusions; and a package colloid filled in the receiving space for covering the LED chips.
