For the implementation of the architecturally sophisticated concept of a special exhibition in the Zeithaus of the Autostadt Wolfsburg, additional luminaires had to be installed without interfering with the existing and partially mirrored ceiling construction. The customer attached particular importance to avoiding unwanted reflections in the high-gloss paintwork of the cars on display. After weighing up the available technologies, special luminaires were developed which, thanks to specially shaped optics and high optical efficiency, allow the individual LEDs of the luminaire to merge into a continuous line. LEDs with a CRI of > 96 were chosen.
