Non-fluorescent color wheel laser projection light source system

The invention provides a non-fluorescent color wheel laser projection light source system, belonging to the field of laser illumination. The non-fluorescent color wheel laser projection light source system solves the problems that the conventional laser projection device has complicated structure, huge size, low heat dissipation efficiency of a fluorescent wheel and the like. The main structure ofthe non-fluorescent color wheel laser projection light source system is a cylindrical barrel with a built-in lens, wherein an annular-shaped surface surrounds the outer side surface of the cylindrical barrel, a certain gap exists between the annular-shaped surface and the cylindrical barrel, the cylindrical barrel can rotate in the annular-shaped surface, and segmented fluorescent powder used forlaser wavelength conversion is painted on the inner side of the annular-shaped surface; and an opening is formed in a position of the cylindrical surface of the cylindrical barrel and is used for allowing laser emergent from
