1. A lighting apparatus, comprising:
first light source configured to emit a first light and including at least one first light emitter and a wavelength converter;
at least one second light emitter configured to emit a second light having a different peak wavelength from a peak wavelength of light emitted from the at least one first light emitter; and
a controller configured to control the first light source and the at least one second light emitter,
wherein:
the peak wavelength of the light emitted from the at least one first light emitter is in a range of blue light;
the different peak wavelength of the second light is in a low visibility range of about 605 nm to about 935 nm;
the wavelength converter comprises one or more wavelength converting materials to convert light emitted from the at least one first light emitter into the first light;
the second light emitted from the at least one first light emitter is emitted to an outside of the lighting apparatus without passing through the wavelength converter; and
the second light includes an irradiance spectrum having a wavelength region with a greater irradiance than an irradiance of the first light emitted from the first light source within the same wavelength region.
