A rotor unit includes a rotor including a substrate and a wavelength conversion region, and a driving unit. The substrate includes an outer edge and is configured such that a substrate material is continuously provided from a center to the outer edge. The wavelength conversion region is provided on the substrate and receives light having a first wavelength region and emits light having a second wavelength region different from the first wavelength region. The driving unit rotates the rotor.
