Abstract: There are provided a light-emitting device and a light-emitting device package capable of simultaneously controlling brightness and correlated color temperature (CCT) of an illumination apparatus using the same. The light-emitting device includes a plurality of light-emitting units each including an active layer of multi quantum wells (MQW) and an electrode unit electrically connected to the light-emitting units. Brightness and CCT of light components generated by the plurality of light-emitting units simultaneously change in accordance with an amount of current applied by an external input power source connected to the light-emitting units through the electrode unit.

Abstract: A semiconductor light-emitting device may include an emission structure, a protection pattern layer on a limited region of the emission structure, and an insulating pattern layer on the emission structure. The protection pattern layer may expose a separate remaining region of the emission structure, and the first insulating pattern layer may cover at least the remaining region of the emission structure. The insulating layer may include an opening that exposes at least a portion of a surface of the protection pattern layer, such that the emission structure remains covered by at least one of the insulating layer and the protection pattern layer.
