Patent ID: 8142060

Claim:
A light source device, comprising: a base board; a first electrode and a second electrode; at least one die bonding pad located adjacent the base board and electrically connected to the first electrode; at least one wire bonding pad located adjacent the base board and the at least one die bonding pad and electrically connected to the second electrode; at least one LED chip having a top surface including adjacent corner regions, a bottom surface located adjacent the at least one die bonding pad, a first chip electrode electrically connected to the at least one die bonding pad, and a second chip electrode forming an edge portion at the top surface of the at least one LED chip and located adjacent the at least one wire bonding pad, wherein the edge portion of the second chip electrode includes at least one of the adjacent corner regions of the top surface located toward the at least one wire bonding pad; a bonding wire electrically connecting the second chip electrode and the wire bonding pad; and an encapsulating resin disposed adjacent the base board and encapsulating each of the at least one LED chip and the bonding wire.
