LUXEXCEL | Uses Cases: Fresnel lenses


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.
