New LED-on-Foil Technology from ams OSRAM Creates Unprecedented Effects in Automotive Lighting

Using ALIYOS  technology, car makers will be able to express brand personality through exterior and interior lighting in previously unattainable ways, as well as to introduce completely new three- dimensional lighting and animation effects for displaying dynamic individual messages and information signals to drivers and other road users.

Gerald Broneske, Vice President Global Product Marketing OS Automotive at ams OSRAM, said: ‘With the release of its ALIYOS technology, ams OSRAM is taking another major step towards strengthening its position as one of the most innovative suppliers of lighting technology in the automotive industry. The introduction of advanced LED-on-foil technology marks a new revolution in the way that LEDs are applied in automotive lighting, giving customers exciting new opportunities todifferentiate vehicle brands.’

Transparent, flexible, thin LED lighting

The ALIYOS technology enables ams OSRAM to apply mini-LEDs on a thin, flexible and transparent substrate. Connected by almost invisible metal traces, the mini-LEDs can be arranged with a large degree of freedom to form individually addressable segments of any shape. They can be positioned to perform standard lighting functions such as a stop light or turn indicator, but with unique, custom shapes and animation effects. The mini-LEDs can also be used to display symbols, words, images or abstract patterns for decoration, information, or warning.

Transparency, an outstanding feature of ALIYOS technology, in combination with mini-LEDs, means that light can appear out of nowhere. In addition, multiple foil assemblies can be placed one behind the other to create dramatic new 3D lighting and animation effects.

ams OSRAM is now working with the world’s leading automotive Tier One suppliers and OEMs to explore the new possibilities in automotive interior and exterior lighting. One demonstration design exploits the transparency of the ALIYOS  foil substrate to produce new 3D effects in rear lights: a transparent array of three ALIYOS  LED foils mounted one behind the other creates a sense of depth.
