Patent ID: 8283682

Claim:
A light emitting diode (LED) comprising: a substrate; and at least three light emitting cells on the substrate, wherein each of the light emitting cells comprises a first semiconductor layer, a second semiconductor layer disposed on the first conductive semiconductor layer, a first electrode formed on an exposed portion of the first semiconductor layer, and a second electrode formed on the second semiconductor layer, wherein first connecting elements are configured to connect at least two of the at least three light emitting cells in series, wherein at least one of the at least three light emitting cells are configured to connect the at least two of the at least three light emitting cells in parallel, at least one second connecting elements are configured to connect the at least two of the at least three light emitting cells to the at least one of the at least three light emitting cells to operate in response to a forward voltage to the at least one of the at least three light emitting cells which configured to operate in response to a reverse voltage, wherein an overvoltage is prevented from being applied to the at least two or the at least one of the at least three light emitting cell in a light emitting cell array group to which the reverse voltage is applied, by the second connecting elements, during an operation by the forward voltage, and wherein the second electrode and the first electrode corresponding to each of the light emitting cells are respectively arranged adjacent to opposite corners in a diagonal direction and are symmetrical to those of light emitting cells adjacent to the one of the at least three light emitting cells.
