PROBLEM TO BE SOLVED: To increase light extraction efficiency while preventing reduction of intensity of white light.SOLUTION: A light emitting module 1 comprises: plural LEDs 13; a wavelength conversion member 25; and a wavelength conversion member 35. The wavelength conversion member 25 converts a part of blue light emitted from the LEDs 13 into a beam of light of a first visible light wavelength band. The wavelength conversion member 35 converts the un-converted light in the light emitted from the LED13 into a beam of light of a second visible light wavelength band. Between the LED13 and the wavelength conversion member 35, neodymium oxide is contained for absorbing light of a wavelength of 570nm to 590nm, and in the wavelength conversion member 35, no neodymium oxide is contained. |
