ZKW and Swarovski let the new BMW i7 shine with crystal headlights
The four precisely cut crystals on each side of the "Iconic Glow" headlights are underlain by individually controlled LEDs. These support the daytime running and indicator lights, creating a vibrant, sparkling glow that is particularly effective during the "Welcome and Goodbye light staging" functions.
In the lower part of the front of the BMW i7, high and low beams are discreetly positioned using ZKW LED matrix technology. The crystal headlights are produced in pan-European manufacturing. The premium crystal light was developed at the headquarters of the lighting systems specialist in Wieselburg, it is manufactured at the Slovakian site in Krusovce, the crystals come from Austria. "The innovative lighting system opens up new dimensions that no longer have anything in common with classic spotlights. With the crystal light, we have created a completely new kind of lighting effect for a premium automobile," says Dr Wilhelm Steger, CEO of the ZKW Group.
The unique project presented the engineers from BMW Group, ZKW and Swarovski with major tasks. In order to make the crystals look like a grown crystal rather than jewellery, a special setting had to be developed. "The challenge was, in addition to developing the unmistakable design with BMW Group, to fix the large glass crystals stably and permanently in the headlamp. The main focus was on perfecting the crystal cut," says Peter Widmann, Senior Vice President and Managing Director of Swarovski Mobility. Special software was developed for the light functions of the "Iconic Glow" headlamp, which enables unique effects. In addition to the driving and flashing light, the premium lighting impresses, for example, with its sparkling "Welcome and Goodbye" light show.
