摘要：
To enhance emission efficiency and color rendering, a light emitting device 1 comprises: at least one light source 3; at least one first emitting section 4 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 3 when excited by the light emitted from light source 3; at least one second emitting section 5 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 4 when excited by the light emitted from light source 3 and first emitting section 4; wherein light emitting device 1 comprises at least one light shielding unit 6 that protects at least a part of the light emitted from first emitting section 4 from entering second emitting section 5.
