Semiconductor light emitting device having multi-cell array

摘要

A semiconductor light emitting device (LED) includes a first light emitting cell having a first plurality of electrodes. A second light emitting cell includes a second plurality of electrodes. The first and second light emitting cells are disposed on the substrate and are physically separated from each other. A first interconnection unit electrically connects the first plurality of electrodes to the second plurality of the electrodes.
