摘要：
A light source unit includes a cylindrical transparent substrate capable of being controlled to rotate; plural segment regions provided at a cylinder portion of a side surface of the cylindrical transparent substrate; layers of different phosphors arranged on at least two of the plural segment regions, the different phosphors being configured to emit light of prescribed wavelength bands upon receiving excitation light; and an excitation light source provided inside or outside of the transparent substrate, the excitation light source being configured to apply the excitation light to the phosphors.
