Description of the Invention: [Technical Field] [0001] The present invention relates to a light conversion module, a light source module, and a projection machine using the same. [Prior Art] [0002] Some existing projectors use blue laser-excited phosphor light to replace green light-emitting diodes. However, in the design of such a projector, the phosphor is usually coated with a fluorescent material on a turntable that is rotated by a motor at a high speed, and then the fluorescent material is illuminated by laser irradiation. However, since the laser energy is very high, The glue on the turntable is easy to ignite under the high pressure of the laser, ..... causes the phosphor to detach from the high-speed turntable, thus affecting the use of the projector. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide a high temperature resistant light conversion component, light green (module and projection using the light source module. :. :::· : ::: id : ;.
