LUXEXCEL | Uses Cases: Fresnel lenses



AUTOMOTIVE FRESNEL LENSES FOR LIGHTING:

The Fresnel lens is used in automotive rear lamps. It concentrates LED light into a square intensity field, as described in the ECE regulations of signal light functions.
With printing technology the lens does not need to be rotationally symmetric which is a big advantage for styling and optimising the intensity for the two axes of emission.



OPTIS OSD Solutions allow you to calculate Fresnel lens optics within seconds, then collimating a lambertian LED emission into a collimated beam with predefined opening angle.

3D printed Test sample:

Process to apply
  • Access OPTIS OSD (or other SPEOS function) to calculate the lens shape
    In OSD function : Input parameters are LED position, position of the optics, angular intensity
  • Automatically calculate the Fresnel lens steps
