Abstract

A lighting device includes a first light-emitting device, a plurality of second light-emitting devices, and a control unit. The first light-emitting device has a first emission spectrum that has a first peak wavelength in a wavelength range from 360 nm to 430 nm and in which a light intensity continuously decreases with decreasing wavelength from the first peak wavelength and with increasing wavelength from the first peak wavelength. Each of the plurality of second light-emitting devices has a second emission spectrum with a second peak wavelength in the range from 360 nm to 430 nm, that has a third peak wavelength in a range from the second peak wavelength to 750 nm, and in which a light intensity continuously decreases with decreasing wavelength from the second peak wavelength and with increasing wavelength from the third peak wavelength. The control unit controls all of the light-emitting devices.
