摘要:
The present invention relates to light-emitting diodes. A light-emitting diode according to an exemplary embodiment of the present invention includes a first group including a plurality of first light emitting cells connected in parallel to each other, and a second group including a plurality of second light emitting cells connected in parallel to each other. Each first light emitting cell and second light emitting cell has a semiconductor stack that includes a first conductivity-type semiconductor layer, a second conductivity-type semiconductor layer, and an active layer disposed between the first conductivity-type semiconductor layer and the second conductivity-type semiconductor layer. At least two light emitting cells of the first light emitting cells share the first conductivity-type semiconductor layer, and at least two light emitting cells of the second light emitting cells share the first conductivity-type semiconductor layer. The first light emitting cells are connected in series to the second light emitting cells.
