Laser light passing rate is only 60% to 70% when focusing, and obtained hot spot is ellipse.When mode of laser group uses 360 straight line lasers
Need to increase by 360 cone reflecting mirrors on instrument, cone reflecting mirror fast axis direction differs greatly with slow-axis direction light power, causes light thick
The phenomenon that thin and brightness unevenness.
Utility model content
The utility model provides a kind of optical fiber for reforming frame for line marking instrument mould group, on the basis of original laser diode, increases shaping
The dispersion angle of optical fiber, laser diode is changed by original 1:3 to 1:4 to 1:1, and laser light type is made to become squarish,
Laser throughput reaches 90% when focusing.

The utility model has the following beneficial effects:
1, original (i.e. laser diode) upper end LD is increased shaping optical fiber by the utility model, reduces the angle of divergence of LD
Degree, light passing rate increases when focusing, and laser light type is approximating square hot spot after optical fiber for reforming, increases power, and loss reduces,
It ensure that the consistency of light.
2, the increase of shaping optical fiber upper end expands eyeglass in the utility model, then focuses using focusing lens, hot spot warp
After expanding eyeglass amplification, hot spot is allow uniformly to be covered with entire focusing lens surface, focuses obtained hot spot light type as circle
Shape, and brightness increases, optical quality is preferable.
3, in order to be applicable in the focusing lens of different focal length, select different multiples expands eyeglass amplification hot spot, makes light shape more
Circle, optical quality are more preferable.
