The link between lighting and ADAS started a decade ago when AFS used it for anticipation of road curves. Then some years later, cameras were integrated into headlighting to bring ADB. The DVN Report published today explains how intelligent lighting functions like ADB, marking light, and future functions not yet commercialised increasingly need sensors, while ADAS sensors reciprocally need lighting to better see obstacles and pedestrians after dark. The report goes into detail about the practical exigencies and design implications of in-lamp integration of sensors and cameras.
The central chapters of the report are dedicated to new lighting functions for safety improvements, made possible by ADAS sensors. A variety of adaptive lighting systems are described in terms of the technologies that work together to automatically and dynamically adapt light in all circumstances of driving: environment, weather, roads, speed, traffic and in the future, driver condition (fatigue, alcohol…) to optimise visibility and conspicuity without glare or distraction. These improvements are on the way thanks to better ADAS sensors, and to the evolution of lighting that will bring more and more high definition systems, based on technologies like DMD and µLEDs. Several technologies are presented for new road projection functions to support the driver, improve safety, and communicate to other traffic participants.
Finally, the report presents the authors’ outlook, considering our civilisation strives for maximum safety in every circumstances. Lighting has demonstrated a strong added value for safety improvement, and that will surely continue—and, indeed, accelerate—going forward, as driver assistants and automated driving systems will need to give information not only to the driver, but also to other road users, while also receiving information from others and from the environment. For these kinds of communication, lighting will be central.
I remind you the two events coming, Smart Interiors Online DVN-I Workshop in September, and VISION congress in October, with 40 lectures and 30 expo booths. See below, information on these two events.
