Abstract: An LED lighting device is provided. The LED lighting device may include a light source configured to emit a light of first color temperature, second color temperature, and third color temperature and a switch electrically connected to the light source to control the light source to emit the lights of the first color temperature, the second color temperature, and the third color temperature, respectively. The light source includes a first light source configured to emit a light of a first color temperature, and a second light source configured to emit a light of a second color temperature that is different from the first color temperature, and the light source emits a light of a third color temperature between the first and second color temperatures when the switch parallel-connects the first light source and the second light source.
