LIGHT-EMITTING DEVICE

摘要

Disclosed is a light-emitting device which comprises: a light-emitting element for emitting a first light in a blue wavelength band; a first wavelength converter for converting the first light into a second light; a second wavelength converter for converting the first light into a third light; and a third wavelength converter for converting the first light into a fourth light, wherein the first to fourth lights have centroid wavelengths which satisfy the following relationship: [Expression 1] λ1 < λ2 <λ3 < λ4 (wherein λ1 is the centroid wavelength of the first light; λ2 is the centroid wavelength of the second light; λ3 is the centroid wavelength of the third light; and λ4 is the centroid wavelength of the fourth light.)
