At the Audi stand at the IAA 2005, our B12-250 LED strips were used to illuminate contours engraved in Plexiglas in the CI color orange.
The light was fed in both from above and below to make the milled contours of the vehicle visible to the observer. The resulting light refraction within the Plexiglas made it possible to generate the desired light intensity of the LED strips by dimming them precisely.
