Abstract:
A lighting device includes: a light source including a light emitting element that emits light having an emission peak wavelength in a wavelength range of 500 nm or less; and first, second and third fluorescent substances on which light emitted from the light emitting element is incident, wherein the first fluorescent substance absorbs at least light emitted from the light emitting element to emit light having a emission peak wavelength in a wavelength range of 500 nm to 580 nm, the second fluorescent substance absorbs at least light emitted from the first fluorescent substance to emit light having a emission peak wavelength in a wavelength range of 580 nm to 750 nm, and the third fluorescent substance absorbs light having a wavelength range of 500 nm or less to emit light having a emission peak wavelength in a wavelength range of 600 nm to 750 nm.
