Abstract
A lighting device includes an LED light source that emits light having a first peak wavelength in a range from 200 to 470 nm and a second peak wavelength in a range from 460 to 700 nm. An emission intensity at the second peak wavelength is greater than an emission intensity at the first peak wavelength, and an emission intensity at a wavelength band of 720 nm or greater is one tenth or less than an emission intensity at the second peak wavelength.
