Patent ID: 8378373

Claim:
A light-emitting device, comprising: a substrate; a stacked structure including a first type semiconductor layer positioned on the substrate, a light-emitting structure positioned on the first type semiconductor layer, and a second type semiconductor layer positioned on the light-emitting structure, wherein the stacked structure includes a depression exposing the first type semiconductor layer; at least two electrode sets disposed on the stacked structure, wherein each electrode set is physically separated from one another, and each of the electrode set comprises: a first electrode positioned on the first type semiconductor layer in the depression, the first electrode including at least one first pad and at least one first extending wire with one end connected to the first pad; a second electrode positioned on the second type semiconductor layer, the second electrode including at least one second pad and at least one second extending wire with one end connected to the second pad; wherein the light emitting structure can be parallel driven through the at least two electrode sets; wherein the distance between the first pad and the second pad is greater than 70% of the width of the light-emitting device; wherein the first electrodes of the at least two sets are positioned in the same depression; and wherein the at least two electrode sets are arranged in mirror-image manner.
