HELLA and Covestro present new designs for vehicle lighting
Together with Covestro, one of the largest polymer manufacturer in the world, lighting and electronics specialist HELLA has developed a new design for vehicle signal lighting using holographic technology. Since 2012, both companies have been pooling their expertise in the areas of plastics technology, as well as design and lighting technology, in order to use signal lighting as a style element. For this reason, the companies have been developing innovative designs for the front and rear lighting of electric cars in collaboration since 2015. Theresult is holographic lighting with 3D effects, as well as a seamless and aerodynamic design.
The rear of the vehicle is comprised of a lamp with three parts, each equipped with holographic technology. With this, the two companies are presenting a world premiere. Designers at HELLA developed the holograms before Covestro then incorporated these into a transparent holographic film, which retains the design and is laminated onto a 3mm glass plate. For series applications in the future, plastic will be used instead of glass. “Holographic films are perfectly suited for integrating different lighting functions into the body in a space-saving and unobtrusive way. The installation depth can be reduced and automotive manufacturers have the possibility to install more compact lamps,” explains Dr. Michael Kleinkes, Head of Development Lighting Technology at HELLA. The holographic film is illuminated from behind using LED light sources and reflectors. This results in a 3D effect – as if the elements are floating freely in space. In both of the outer elements of the rear lamp, a hologram was inserted with numerous illuminating areas (“flakes”). Integrated into the tailgate is the middle lamp, on which the HELLA and Covestro company logos appear to be floating.
