Projector light source including wavelength conversion member having porous ceramic substrate
A wheel-shaped wavelength conversion member includes a first porous ceramic layer having a porosity of at least 20% by volume, a phosphor layer formed on a first principal surface of the first porous ceramic layer, a ceramic heat dissipation layer having a porosity of 20% or less by volume provided on a second principal surface of the first porous ceramic layer opposite the first principal surface, and a second porous ceramic layer having a porosity of at least 20% by volume provided on a surface of the heat dissipation layer opposite the first porous ceramic layer.
