ABSTRACT:
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.
