To improve an R12 value, the present invention includes a light emitting device which emits a first beam of a blue wavelength range, a first wavelength conversion body which converts the first beam into a second beam, a second wavelength conversion body which converts the first beam into a third beam, and a third wavelength conversion body which converts the first beam into a fourth beam. The center wavelengths of the first to the fourth beam satisfy an equation 1 which is λ1<λ2<λ3<λ4 (here, λ1 is a center wavelength of the first beam, λ2 is a center wavelength of the second beam, λ3 is a center wavelength of the third beam, and λ4 is a center wavelength of the fourth beam). |
