Patent ID: 8786074

Claim:
A packaging device for matrix-arrayed semiconductor light-emitting elements of high power and high directivity, the packaging device comprising: a metal base having a supporting surface with a first electrode area and at least one second electrode area disposed thereon, said first electrode area and said at least one second electrode area being electrically isolated via an insulating structure; an array chip disposed on said first electrode area, wherein a plurality of matrix-arranged semiconductor light-emitting elements and at least two wire bond pads adjacent to said light-emitting elements are disposed on an active side of said array chip, wherein said light-emitting elements are arranged as a tetragon and said at least two wire bond pads are distributed on different sides of said tetragon; and a plurality of metal wires connected between said at least two wire bond pads and said at least one second electrode area; wherein, a pole of said at least one second electrode area is opposite to another pole of the first electrode area; said at least two wire bond pads are connected by the metal wires to said at least one second electrode area and thus are of the same pole as said at least one second electrode area; wherein the number of said second electrode area is two and both these two second electrode areas are of the same pole.
