Adaptive driving beam
Advanced adaptive driving beam technology for precise, glare free forward illumination in all driving conditions
Intelligent adaptive driving beam for glare free, high‑visibility forward lighting
Adaptive driving beam (ADB) systems maximize visibility while avoiding glare for oncoming traffic by intelligently shaping the high-beam pattern.
With increasing safety and innovation requirements, ADB has become a key feature of modern automotive lighting. ams OSRAM supports this development with high-performance LEDs, lasers, and pixel technologies such as EVIYOS™, enabling precision, safety, and advanced styling.
What are adaptive driving beam systems?
Adaptive driving beam systems – also known as adaptive front lighting systems – dynamically adjust the illuminated area instead of projecting a fixed beam pattern. Based on sensor input, typically from an onboard camera, the system modifies the beam distribution in real time. This enables intelligent lighting functions that improve visibility while maintaining compliance with glare free operation.
Why are adaptive driving beams important?
Unlike static low-beam or high-beam systems, adaptive driving beams react to road curvature, vehicles ahead, and other traffic participants. By selectively shaping the high-beam pattern, ADB prevents light from shining into the eyes of oncoming drivers while preserving maximum illumination elsewhere. This significantly improves night-time visibility and comfort. High-definition ADB (HD ADB) systems offer a much higher resolution, enabling finely structured, glare free lighting tailored to the driving environment.
Technology overview: discrete LEDs, LED modules and pixelated LEDs
Adaptive driving beam solutions differ mainly in resolution. Entry-level ADB can be implemented using arrays of discrete LEDs, offering limited segmentation for basic adaptive functions. More advanced systems use LED modules with dozens of individually controllable pixels, enabling improved curve lighting and selective deglaring. For high-definition ADB, pixelated or matrix LEDs provide several thousand individually addressable pixels. These allow highly precise beam shaping and are increasingly required by legislation in certain regions. In applications demanding even higher pixel counts—for example, for projection or entertainment functions— digital mirror devices (DMD) or liquid crystal on silicon (LCoS) imager can achieve resolutions up to the megapixel range, albeit with tradeoffs in brightness. For more information on light sources for those imager-based systems go to our projection LEDs page.
FAQ: Below are some of the most common questions about adaptive drive beam
A pixelated or matrix light refers to a pixelated or matrix light refers to a pixelated LED or matrix LED in which many individual segments can be controlled independently.
ADB systems provide lighting that adapts to the driver’s needs — from simple curve lighting for better visibility to advanced high‑definition systems that enable glare‑free high‑beam operation.
High‑definition ADB systems contain a large number of individually addressable segments, allowing a very finely structured light distribution. For example, they can selectively remove only the glare‑causing areas of the high-beam from the field of an approaching vehicle, greatly improving visibility without distracting or dazzling other road users.
