摘要	A wavelength conversion member, comprises: a substrate; a first wavelength conversion layer on the substrate, the first wavelength conversion layer containing a first phosphor and a first matrix; and a second wavelength conversion layer containing a second phosphor, first inorganic particles, and a second matrix. The first phosphor and the second phosphor convert at least part of the excitation light incident on the second main surface into first light having longer wavelengths than the excitation light. The first light is emitted from the second main surface of the second wavelength conversion layer. A volume Vp1 of the first phosphor, a volume Vw1 of the first wavelength conversion layer, a volume Vp2 of the second phosphor, and a volume Vw2 of the second wavelength conversion layer satisfy Vp1/Vw1>Vp2/Vw2.
其他摘要	波长转换构件，包括：基板;基板上的第一波长转换层，第一波长转换层包含第一荧光体和第一基体;第二波长转换层包含第二磷光体，第一无机颗粒和第二基质。第一磷光体和第二磷光体将入射在第二主表面上的激发光的至少一部分转换为具有比激发光更长波长的第一光。第一光从第二波长转换层的第二主表面发射。第一荧光体的体积Vp1，第一波长转换层的体积Vw1，第二荧光体的体积Vp2和第二波长转换层的体积Vw2满足Vp1 / Vw1> Vp2 / Vw2。
