国际汽车照明研讨会（ISAL）

Impuls Speech: Digital Light – A Journey of an Automotive Vision 
Speaker: Stefan Groetsch, Director Hard- & Software Development at ams OSRAM

Date and time: Tuesday, September 23, 17:00 - 17:10

This keynote highlights the evolution of automotive lighting from static illumination to high-resolution, software-controlled HD light systems. It reflects on how innovation in optics, electronics, and embedded intelligence has enabled dynamic projections, adaptive beam patterns, and communication between vehicles and their environment. Recognized by the Deutscher Zukunftspreis, this technology marks a milestone on the path to fully software-defined lighting. The presentation offers a glimpse into a future where light is not just seen—but understands.

Integrated area-light sources in RCL pave the way for new automotive signal lighting applications
Speaker: Dr. Erwin Lang, Senior Project Manager within Automotive Hardware-/Software Engineering at ams OSRAM

Date and time: Tuesday, September 23, 17:20 - 17:30

Approaches like ‘hidden until lit’ describe trends in automotive interior lighting applications, where the light sources remain hidden until they are needed or turned on. Integrating the light source behind semi-transparent surfaces makes them practically invisible when not in use. This trend is now arriving at a high pace in automotive exterior lighting applications. The lighting designers try to hide the light sources either behind black surfaces or behind any individually designed surfaces (like e.g. technical patterns or gradient designs). This requires entirely new possibilities for integrating future lighting solutions. 
To support this trend, we have developed a rear combination lamp (RCL) prototype based on ams OSRAM’s ALIYOSTM technology combined with LEONHARD KURZ’s capabilities for In-Mold Decoration (IMD) and Functional Foil Bonding (FFB) Adhesive process. The RCL´s outer lens gets a semi-transparent colored surface via IMD. The ALIYOSTM LED-foils are integrated on the back side of the outer lens by FFB Adhesive and are thereby invisible due to the decorated surface. Only when the lighting function is turned on, the lighting signature becomes visible. The FFB Adhesive process has been further optimized to allow the integration of the LED-foil on 2.5D curved surfaces as well as the stitching of several LED-foils next to each other.
Thanks to the transparency of the ALIYOSTM technology, additional light solutions can be placed directly behind the emissive area of the ALIYOSTM LED-foil. This combination of both technologies – the LED-area light source with traditional approaches based on latest developments of ams-OSRAM’s SYNIOSTM LED family – allows for boosted light emission for functions such as stop, turn indicator and reverse lighting, respectively. Indication of autonomous driving within the RCL is demonstrated. Based on the RCL prototype, simulation results and measurement data will be discussed.
This combined approach allows for more dynamic and customizable lighting solutions, enhancing both the aesthetic and functional aspects of automotive lighting design.
 

Contrast Optimization for Camera-Based ADAS to Enhance Object Visibility Using Pixel Light Technology
Speaker: Markus Hofmann, System Solution Engineer at ams OSRAM) & Julian Lerch, TU Darmstadt
Date and time: Wednesday, September 24, 13:30 - 13:40

Micro LED pixel emitter arrays are transforming automotive forward lighting by providing highly detailed and versatile beam patterns. Their high resolution and pixel density allow for the development of adaptive ADB headlamps and glare-free high beams, while also boosting energy efficiency and sustainability. ams-OSRAM and TU Darmstadt work together to analyze German traffic scenarios  and simulate them to evaluate how different pixel counts and headlamp configurations affect light distribution and overall headlamp performance in various nighttime environments.
