1. A lighting device comprising:
a first light emitter comprising a plurality of first light sources each being configured to emit light with a different color temperature;
a second light emitter comprising at least one second light source configured to emit light having a longer peak wavelength than that emitted from 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 user interface configured to receive input of a user and connected to the controller;
wherein each of the first light sources comprises a light-emitting diode chip and a wavelength converter configured to convert a wavelength range of light emitted from the light-emitting diode chip, and
wherein the controller is further configured to disable the second light emitter in response to receiving an input for prohibiting emission of the second light source through the user interface.
