1. A lighting device comprising:
a first light emitter including a plurality of first light sources each being configured to emit white light having a color temperature that is greater than 4,000K, at least one of the plurality of first light sources including a light-emitting diode chip and a wavelength converter configured to convert a wavelength range of light emitted from the light-emitting diode chip;
a second light emitter configured to emit light having a color temperature that is less than 4,000K and a peak wavelength that is longer than a peak wavelength of the light emitted from the light-emitting diode chip of the at least one of the plurality of first light sources;
a controller configured to adjust characteristics of light emitted from the first light emitter and the second light emitter; and
a sensor connected to the controller and configured to detect a motion of an external object,
wherein the controller is further configured to disable at least one of the first light emitter or the second light emitter when no motion is detected.
