1. A lighting apparatus, comprising:
a white light emitting device including at least one first light emitter and a wavelength converter to implement white light;
at least one second light emitter configured to emit light having a peak wavelength different from a peak wavelength of light emitted by the at least one first light emitter; and
a controller configured to control the white light emitting device and the at least one second light emitter,
wherein:
the at least one first light emitter is configured to emit the light having the peak wavelength in a range of blue light;
the white light emitting device is configured to emit light having a peak wavelength in a range of about 430 nm to about 470 nm;
the at least one second light emitter is configured to emit the light having the peak wavelength in a range of about 605 nm to about 935 nm;
the wavelength converter includes a plurality of wavelength conversion substances to convert the light of the at least one first light emitter into white light; and
the light emitted by the at least one second light emitter includes a region in an irradiance spectrum having an irradiance that is greater than an irradiance of light emitted from the white light emitting device at a same wavelength.
