Low-power-consumption low-cost stray-light-free integral sighting telescope light source structure

The invention provides a low-power-consumption low-cost stray-light-free integral sighting telescope light source structure, which relates to the technical field of semiconductor photoelectric devices and optical lenses, and comprises an eyepiece and a reflecting mirror which are positioned on a sighting telescope, and an integral light source assembly which is positioned between the eyepiece and the reflecting mirror in the sighting telescope and faces the reflecting mirror, the overall light source assembly comprises a diaphragm, a laser tube and a die bond PCB, the diaphragm is installed on the die bond PCB, the laser tube is located between the die bond PCB and the diaphragm, a reticle is replaced by the diaphragm, a laser illumination light source is selected to be combined into an overall structure, the reflector is designed in an optical imaging mode, the reticle, gluing and epoxy resin packaging processes are omitted, and the overall light source assembly is more compact. The defects of light leakage,
