Abstract
A lighting device is provided with an illumination unit including two or less LED light sources. The illumination unit uses the two or less LED light sources to emit light of a short wavelength band and light of a long wavelength band. An output varying unit functions to vary an output of at least the long wavelength band light. When the output varying unit receives a varying signal, the output varying unit functions to decrease the output of at least the long wavelength band light.
