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

  • the first LASER Light Source, collimating components, reflection part, the first light concentrating components, dichroic parts, driver part, wavelength convert parts, the 3rd light concentrating components and light-receiving member;

    Wherein, described wavelength convert parts at least comprise corresponding with primary importance, that transmission has the light beam of first wave length printing opacity through hole, the first cavity that is corresponding with the second place, that be excited to export second light beam with second wave length, and the second cavity that is corresponding with the 3rd position, that be excited to export the 3rd light beam with the 3rd wavelength;

    Described first LASER Light Source, for exporting first light beam with first wave length to described collimating components;

    Described collimating components, for carrying out collimation process to the first light beam received, obtains parallel beam, and exports described parallel beam to described reflection part;

    Described reflection part, for reflexing to described first light concentrating components by described parallel beam;

    Described first light concentrating components, exports described dichroic parts to after being assembled by the parallel beam received;

    Described driver part, for moving to multiple assigned address according to steering order by described dichroic parts;

    Wherein, described multiple assigned address at least comprises;

    primary importance, the second place and the 3rd position;

    Described dichroic parts, for the beam reflection extremely described wavelength convert parts exported by described first light concentrating components;

    Described wavelength convert parts, for when described dichroic parts are positioned at primary importance, are transmitted through described 3rd light concentrating components by the received light beam with first wave length;

    When described dichroic parts are positioned at the second place, be excited to export second light beam with second wave length according to received light beam, and export described second light beam to described 3rd light concentrating components;

    Also for when described dichroic parts are positioned at the 3rd position, be excited to export the 3rd light beam with the 3rd wavelength according to received light beam, and export described 3rd light beam to described 3rd light concentrating components;

    Described 3rd light concentrating components, exports described light-receiving member to after assembling received light beam.
