To enhance emission efficiency and color rendering, a light emitting
device includes: at least one light source; at least one first emitting
section having at least one sort of luminescent material that can emit
light including a wavelength component that is longer than the light
emitted from light source when excited by the light emitted from light
source; at least one second emitting section having at least one sort of
luminescent material that can emit light including a wavelength component
that is longer than the light emitted from first emitting section when
excited by the light emitted from light source and first emitting
section; wherein light emitting device includes at least one light
shielding unit that protects at least a of the light emitted from first
emitting section from entering second emitting section.
