Abstract:
1. 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 one wire bond pad 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 the number of said wire bond pads is at least two and distributed on different sides of said tetragon; and a plurality of metal wires connected between said at least one wire bond pad and said at least one second electrode area; wherein at least one second electrode area among said second electrode areas is an L-shaped structure located at a corner of said array chip.
