ams OSRAM unveils ALIYOS LED-on-foil technology for automotive lighting

At the International Symposium on Automotive Lighting (ISAL 2023) in Darmstadt, Germany (25-27 September), ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has unveiled ALIYOS LED-on-foil technology, which it says opens up new possibilities for design freedom and creativity in automotive lighting.

Using ALIYOS technology, car makers can “express brand personality” through exterior and interior lighting in previously unattainable ways, the firm adds, as well as introducing new three-dimensional lighting and animation effects for displaying dynamic individual messages and information signals to drivers and other road users.

“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 to differentiate vehicle brands,” says Gerald Broneske, VP global product marketing OS Automotive at ams OSRAM.

Transparent, flexible, thin LED lighting

ams OSRAM says that ALIYOS technology enables it to apply mini-LEDs on a thin, flexible and transparent substrate. 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, 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 new 3D lighting and animation effects.

ams OSRAM is now working with 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.

Another design shows that ALIYOS LED-on-foil technology can be applied to curved body panels, and is invisible when turned off, creating the effect of ‘Light out of nowhere’.

Due to the transparency, thinness and flexibility of ALIYOS technology, thousands of other new design possibilities are now open to car manufacturers, says the firm. Legal requirements, for example UN Regulation No. 148 for the brightness of rear light and stop lights as well as turn indicators, can be met through the application of ALIYOS technology, it adds.

Industrialization of the technology has begun. The aim is to enable the first cars to be equipped with ALIYOS technology by the end of 2025, and to have achieved qualification for compliance with automotive quality and safety standards by this time.
