  • Publication number: 20130107573
    Abstract: Provided is a wavelength conversion element that can prevent damage to the wavelength conversion element during the use of the light source and reduce the decrease in intensity of light emitted from the light source equipped with the wavelength conversion element during the use of the light source. The wavelength conversion element 20 includes a wavelength conversion substrate 21 and a reflective layer 24. The wavelength conversion substrate 21, upon incidence of excitation light L0, absorbs part of the excitation light L0 to emit light of different wavelength from the excitation light L0. The reflective layer 24 is disposed on one surface 21b of the wavelength conversion substrate 21. The reflective layer 24 is made of a metal or an alloy.
