  • Patent number: 11916175
    Abstract: A light emitting device includes a semiconductor light emitting element which emits excitation light having a peak wavelength in a range of 440 to 450 nm and a fluorescent body layer which is provided on the semiconductor light emitting element, is excited by the excitation light from the semiconductor light emitting element, and contains a first fluorescent body and a second fluorescent body which emit first fluorescent light and second fluorescent light. The first fluorescent light has a peak wavelength in a range of 540 to 575 nm, and the second fluorescent light has a peak wavelength in a range of 590 to 605 nm. In mixed color light of the radiation light, the intensity of the radiation light of the semiconductor light emitting element is 1/10 to 1/60 of the intensity of the combined light of the radiation light from the first fluorescent body and the second fluorescent body.
