    • Disclosed are a light emitting device and a lighting system having the same. The light emitting device includes a first conductivity-type semiconductor layer, an interfacial layer including at least two superlattice structures adjacent to the first conductivity-type semiconductor layer, an active layer adjacent to the interfacial layer, and a second conductivity-type semiconductor layer adjacent to the active layer. The first conductivity-type semiconductor layer, interfacial layer, active layer, and second conductivity-type semiconductor layer are stacked in a same direction, the first and second semiconductor layer are of different conductivity types, an energy band gap of the superlattice structure adjacent to the active layer is smaller than an energy band gap of the superlattice structure adjacent to the first conductivity-type semiconductor layer.
