Abstract

PROBLEM TO BE SOLVED: To provide a light-emitting device which emits a high luminous flux of high color rendering properties, especially, a light-emitting device which emits warm white light.SOLUTION: The light-emitting device includes a luminous element and a phosphor layer. The luminous element is a blue luminous element that emits light which has the luminescence peak in a wavelength region of 440 nm or more and less than 500 nm. The phosphor layer includes: a green phosphor which contains Euor Ceas the emission major ions; and a red phosphor of a nitride or an oxynitride containing Euas the emission major ions. The green phosphor and the red phosphor emit light by being excited by the light emitted by the blue luminous element. The light-emitting device outputs light which includes light components emitted from the green phosphor, the red phosphor and the blue luminous element. The green phosphor has the excitation peak at the shorter wavelength side than the excitation wavelength which is the peak of the light emitted by the blue luminous element. The red phosphor is a nitride-aluminosilicate-based red phosphor.
