波长转换元件、光源装置、投影仪
摘要：
本发明提供波长转换元件、光源装置、投影仪，能够提高光的利用效率，取出更多的光。本发明的波长转换元件具备：基板；反射部，其设置于所述基板的一个面侧；波长转换层，其设置于所述反射部的与所述基板相反的一侧，并通过激励光的照射发出荧光；以及反射面，其设置于所述波长转换层的与所述反射部相反的一侧的面和所述反射部之间，使所述荧光中的以临界角以上的角度入射的光全反射。
摘要（英）：

A wavelength conversion element includes a substrate, a reflecting section disposed on one surface side of the substrate, a wavelength conversion layer disposed on an opposite side of the reflecting section to the substrate, and emitting fluorescence in response to irradiation with excitation light, and a reflecting surface disposed between a surface of the wavelength conversion layer on an opposite side to the reflecting section and the reflecting section, and adapted to totally reflect light having been input at an angle no smaller than a critical angle out of the fluorescence.
