Patent ID: 10134959

Abstract:
A light emitting device includes a first phosphor emitting a fluorescence having a peak emission wavelength of not less than 445 nm and not more than 490 nm, a second phosphor emitting a fluorescence having a peak emission wavelength of not less than 491 nm and not more than 600 nm, a third phosphor emitting a fluorescence having a peak emission wavelength of not less than 601 nm and not more than 670 nm, and a light emitting element that emits a light having a peak emission wavelength at a shorter wavelength side than the peak emission wavelength of the first phosphor. 0.586≤x≤0.734, 0.017≤y≤0.081, 0.239≤z≤0.384 and x+y+z=1 are satisfied, where x, y, z are defined as mass ratios of the first, second and third phosphors, respectively, to a total mass of the first, second and third phosphors.
