1. a light supply apparatus, is characterized in that, comprising:

  • blue-light semiconductor laser instrument, red-light source, transmission-type fluorescent plate and dichroic mirror;

    On described transmission-type fluorescent plate, be formed with;

    the transmission area that the blue light producing for described blue-light semiconductor laser instrument sees through and the green fluorescence tagma that is subject to described blue-light excited generation transmit green;

    Described dichroic mirror, a branch of for making to be synthesized by the light of described transmission-type fluorescent plate transmission and the ruddiness that produced by described red-light source, to form light source;

    Described transmission-type fluorescent plate comprises by transparent material makes substrate;

    On the first surface of described substrate, be coated with and make described blue light transmission, and make the optical thin film of described green glow reflection;

    The described Optical Coatings Surface in described green fluorescence tagma is coated with green emitting phosphor;

    Described blue light is from described substrate, relative with described first surface second surface incident;

    Or described transmission-type fluorescent plate comprises by transparent material makes substrate;

    On the first surface of described substrate, be coated with and make described blue light transmission, and make the optical thin film of described green glow reflection;

    Position corresponding to described green fluorescence tagma on described substrate, relative with described first surface second surface is coated with green emitting phosphor;

    Described blue light is from the first surface incident of described substrate;

    The substrate of described transmission-type fluorescent plate transmission area is removed.
