Patent ID: 7049639

Claim:
An LED packaging structure including a substrate having opposite upper and lower surfaces and surrounding edges of said LED packaging structure, a conductive pad and a conductive strip formed on the upper surface of the substrate, and a first and second electrode pads formed on the lower surface of the substrate, a light-emitting chip arranged on the conductive pad and electrically connected to the conductive pad and the conductive strip, the light-emitting chip being encapsulated by a protection colloid on the upper surface of the substrate, the LED packaging structure comprising: a pair of holes extending through said substrate between the upper and lower surfaces thereof, each of said pair of holes having walls circumferentially surrounding a cylindrically shaped hole channel; and two conductors, each extending along said walls of a respective one of said pair of holes and covering said walls in closedly surrounding relationship with said hole channel, respectively, wherein one of said two conductors is connected at both ends thereof to the conductive pad and the first electrode pad, respectively, and another one of said two conductors is connected at both ends thereof to the conductive strip and the second electrode pad, respectively, wherein said conductive pad and said conductive strip formed on the upper surface of the substrate, and said first and second electrode pads formed on said lower surfaces of the substrate are displaced from said surrounding edges of said LED packaging structure a predetermined distance.
