US Patent 9472724 Semiconductor light emitting element

The present disclosure relates to a semiconductor light emitting element. The semiconductor light emitting element has a first conductivity type layer, a light emitting layer, and a second conductivity type layer that are laminated; a first pad electrode provided to the first conductivity type layer; and second pad electrodes provided to the second conductivity type layer. The first pad electrode and the second pad electrode is disposed on the same side of the semiconductor light emitting element. Plan view shape of the semiconductor light emitting element is rectangular. The first pad electrode is disposed in a middle region of three regions of the semiconductor light emitting element. The three regions are defined by dividing the light emitting element into three equal parts in the lengthwise direction of the semiconductor light emitting element. The second pad electrodes are respectively disposed in regions on both sides of the three regions.
