Patent ID: 7429755

Claim:
A high power light emitting diode, comprising: a substrate; an N-type semiconductor layer overlaid on the substrate; an active layer formed on a part of the N-type semiconductor layer; a P-type semiconductor layer overlaid on the active layer; at least one N-type electrode placed on a surface of the N-type semiconductor layer uncovered by the P-type semiconductor layer; a transparent conductive layer overlaid on the P-type semiconductor layer and surrounding the N-type electrode; at least one P-type electrode surrounding the N-type electrode and being placed on the transparent conductive layer; and a groove in the transparent conductive layer and the P-type electrode, transversely extending from one edge of the transparent conductive layer adjacent to one edge of the substrate to the vicinity of the N-type electrode, to prevent electrical short between the N-type electrode and an exterior connection.
