Abstract
A light-emitting device in an aspect of the present invention includes at least one light emitter, a first phosphor, and a second phosphor. The first phosphor emits, in response to light emitted from the at least one light emitter, light having a first peak wavelength in a wavelength region of 400 to 480 nm. The second phosphor emits, in response to light emitted from the at least one light emitter, light having a second peak wavelength in a wavelength region of 480 to 600 nm. The at least one light emitter has a third peak wavelength in a wavelength region of 280 to 315 nm and emits light in the wavelength region of 280 to 315 nm.
