Laser lighting source adopting optical waveguides

The utility model relates to a laser lighting source adopting optical waveguides. The laser lighting source comprises six or more blue laser diodes; the wavelength of each blue laser diode is 450 nm; the output end of each blue laser diode is butted with the input end of a corresponding optical fiber through a corresponding lens; the output end of each optical fiber is butted with the input end of the corresponding optical waveguide arranged on a quartz baseplate optical waveguide chip; the quartz baseplate optical waveguide chip comprises six or more optical waveguides, and gathers light paths at a light emergent end; the light emergent end of the quartz baseplate optical waveguide chip directly faces a prism coated with yellow phosphor powder; the prism converts linear emergent light into uniformly diffused white light; the divergence angle of the uniformly diffused white light is 40 degrees; each blue laser diode, each optical fiber, the quartz baseplate optical waveguide chip and the prism are fixedly encapsulated into a whole through gel; the light output surface of the prism is arranged outside the gel. The laser lighting source is small in size, convenient to encapsulate independently, higher in vibration resistance and damage resistance, and free of dust contamination and impurity contamination.
