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.
