Abstract:
The vehicle light-emitting device includes a light-emitting element having a peak emission wavelength of 400 nm or greater and 510 nm or less, and a fluorescent member including a first phosphor excited by light emitted by the light-emitting element and emitting light having a peak emission wavelength of 480 nm or greater and 530 nm or less a second phosphor excited by the light emitted by the light-emitting element and emitting light having a peak emission wavelength of 540 nm or greater and 600 nm or less. The vehicle light-emitting device emits light in a region AL in a CIE1931 chromaticity diagram as defined in the present disclosure.
