Beschreibung
Zusammenfassung:	A light-emitting device includes a light emitter including a light-emitting portion that emits first emission light having a first peak wavelength in a range of 380 to 425 nm and a half width of 15 to 35 nm, and a coating located over the light-emitting portion of the light emitter and containing phosphors to emit second emission light having a second peak wavelength in a range of 430 to 475 nm and having a third peak wavelength in a range of 490 to 540 nm. The light-emitting device emits external emission light having a peak region including the first peak wavelength, the second peak wavelength, and the third peak wavelength 14P02303 and having a long wavelength region defined between an upper end of the range of the third peak wavelength and a wavelength of 750 nm in which a light intensity decreases continuously.
