1. one kind is used to provide heterogeneous light lighting device, comprising:

  • Light source, it is used to produce exciting light, and said exciting light is a blue light;

    Template, it comprises two or more subregions, one or more each the self-contained material for transformation of wave length in the wherein said subregion, this material for transformation of wave length can absorb said exciting light and send wavelength and be different from the said light that excites light wavelength,Wherein, first subregion comprises first material for transformation of wave length, and second subregion does not comprise material for transformation of wave length,Wherein, the part of said template is disposed on the optical path of said exciting light, and wherein said template and said exciting light are removable relative to each other, so that different subregion is exposed to said exciting light in different time;

    AndDichroic element, it is set between said material for transformation of wave length and the said light source, the light that said exciting light of said dichroic element transmission and reflection are sent by said material for transformation of wave length.
