Abstract
Embodiments provide a light-emitting device comprising: a light-emitting element configured for emitting excited light; a first wavelength conversion material to partially absorbs the excited light and emits light with a first emission wavelength; a second wavelength conversion material to partially absorbs the excited light and emits light with a second emission wavelength; and a third wavelength conversion material to partially absorbs the excited light and emits light with a third emission wavelength, wherein the first emission wavelength has a first emission peak at 530 nm to 540 nm, the second emission wavelength has a second emission peak at 550 nm to 560 nm, the third light-emitting device has a third emission peak at 620 nm to 650 nm.
