Abstract:
In a lighting apparatus which emits light of a desired wavelength by irradiating excitation light from a light source to a wavelength converting member, a structure is such that a part of wavelength-converted light which is launched from the wavelength converting member is made to launch from an irradiated-light emerging area without making the light incidence again to the wavelength converting member.
