SEMICONDUCTOR LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting device in which chromaticity variation is reduced and a red color rendering property is improved.

SOLUTION: The semiconductor light-emitting device is characterized by: a semiconductor light-emitting element that emits first-wavelength light; a first phosphor that absorbs the first-wavelength light and emits second-wavelength light having a wavelength longer than that of the first-wavelength light; and a second phosphor that absorbs the first-wavelength light and emits third-wavelength light having a wavelength longer than that of the second-wavelength light; wherein the first phosphor and the second phosphor are expressed by a common chemical composition formula and the first-wavelength light, the second-wavelength light and the third-wavelength light yield mixed-colored light emission.
