发明名称 LIGHT EMITTING ELEMENT
摘要 PROBLEM TO BE SOLVED: To provide a light emitting element capable of preventing wave-length converted light from being extinguished through reabsorption into a phosphor, also capable of preventing wave-length converted light from being extinguished through reentrance into an LED, and further capable of preventing light, which is emitted from an LED for emitting long wavelength light, from being lost by an LED for emitting short wavelength light or by a phosphor.SOLUTION: A light emitting element comprises: a light emitting diode 23 disposed on a substrate 20 to emit light of a first wavelength; a transparent molding part 25 enclosing the light emitting diode; a lower wavelength conversion material layer 27 disposed on the transparent molding part and containing a phosphor converting the light of the first wavelength emitted from the light emitting diode into light of a second wavelength longer than the first wavelength; and an upper wavelength conversion material layer 29 disposed on the lower wavelength conversion material layer and containing a phosphor converting the light of the first wavelength emitted from the light emitting diode into light of a third wavelength, which is longer than the first wavelength but shorter than the second wavelength.
