Modern intelligent lighting systems enhance the driving safety especially for nighttime driving. 
In combination with modern Automotive Driving Assistance Systems the safety benefit also includes daytime driving situations.
Exterior communication with lighting will be a need for future autonomous driving cars, the first “words” in communication are already existing.
This will let other road users profit from the ADAS of modern cars, they can obviously see the intention of the car, not only the driver intention.
This will be explained in detail with a first view on the all new Audi Q7 and additionally with a short glimpse on the Interior of the announced Audi Q9.

Bentley has crafted wood, leather and metal for over 100 years. With the same attention to detail Bentley wants to craft light - The Fourth Material.
Naomi Saka, Lead Lighting Designer at Bentley, designs light and experiences with a software derived from the immersive art industry bridging design and production implementation. Moving from predefined sequences to adaptive dynamic experiences that are responsive to your journey. With this new way of working Bentley bridges design and production implementation on their Bentley bespoke ECU. She is inspired by things that are timelessly beautiful to humans, like the sun dancing on the ocean or light falling through leaves. 
The recent work on the Bentley EXP 15 was awarded Best Lighting Design Team at the CDN Awards, recognising a new era of curated, adaptive luxury.
 

The development of future automotive lighting systems is becoming increasingly complex, requiring interdisciplinary expertise from the first design concept to series production. This presentation highlights technical challenges and innovative solutions across different phases of the product development process.
Topics include the translation of initial lighting design ideas into feasible system architectures, AI-based approaches for lighting system simulation and optimization, as well as smart diagnostic and validation concepts for end-of-line testing in production environments.
Using practical use cases from automotive interior lighting development, the presentation demonstrates how intelligent software tools, connected system architectures, and data-driven engineering methods are transforming the development of next-generation lighting systems. The goal is to show how design ambitions, technological feasibility, and industrial scalability can be successfully combined.

Architectural lighting is moving beyond basic illumination, with greater focus on visual comfort, integration, flexibility and sustainability. Anna Bernaldez Müller opens with a concise overview of the key trends influencing today’s lighting landscape, including optimum light quality and output, more responsive spaces and light source miniaturization, which gives designers greater freedom. Xavier Denis will then explore how specific developments in architectural lighting are being applied to automotive lighting inside and around the vehicle, supporting personalized user experiences, safety and wellbeing.

Automotive multi-color ambient lighting with RGB-W LEDs enables distinctive user experiences but must satisfy strict environmental and performance constraints. This talk outlines the automotive boundary conditions. Fundamentals of human color vision, and color mixing principles are reviewed to motivate system design.
Key challenges of RGB-W LEDs are discussed, such as brightness and color bins and the dependency of photometric and colorimetric behavior on forward current, and junction temperature. Resulting compensation needs are addressed via characterization and calibration approaches.
The role of cost-efficient automotive electronics is examined, focusing on MCU-based control without additional sensors, PWM resolution limits, and memory constraints. Finally, achievable performance is evaluated through statistical color gamut, color and flux accuracy.

The ECE regulations for lighting and light signaling describe the technical requirements for components and systems. New technologies require such regulations or extensions of existing regulations to be approved for use on the road.

This presentation provides an overview of the progress of the regulatory development in the GTB (Lighting and Light Signaling Expert Group) and the adoption process in the GRE (Groupe de Rapporteur de l'Eclairage) at the United Nations in Geneva. Work in progress and future projects will be presented.
