Executuve summary
The 11th DVN Workshop was held in Shanghai, China, on 21-22 April of 2015. A recordbreaking 320 attendees represented automakers, tier-1 and -2 suppliers, researchers, regulators, practitioners, designers, and individuals who develop, build, specify, and regulate vehicle lighting around the world. We asked worldwide experts to share their views and news under the rubric Innovation in Lighting: Safety and Styling. Topics included LED, laser, and OLED lighting, numerous perspectives on ADB, new issues in simulation and regulation, and discussion of specificities particular to the Chinese realm. Two keynotes, 25 presentations and four round table panel discussions illustrated how each contributor sees the technology and how they might be focusing their choices on investments in engineering, materials, people, and production.
In every presentation, common themes built the consensus developed at the workshop: automotive lighting has dramatically changed in recent years, the rate of change is accelerating, and its future will become more complex and interesting with styles continuing to become more diverse and innovative.  Today in 2015, design and creative styling are already greatly influencing how lighting will be engineered and in many cases, posing a significant engineering challenge to incorporate the visual cues of the design and deliver it to production.

A captivating keynote address was delivered by noted design expert Robert Miller, explaining how brands are asserting their identities passionately with light.

Session 1, chaired by Rainer Neumann, centred on carmakers’ visions on front and rear lighting throughout the world. Wolfgang Huhn described Audi's light strategy considering, æsthetics, dynamics, and interaction. Then Michael Meyer from Ford talked about the challenges around the world for a global beam pattern, followed by François Bedu who presented the Renault strategy on lighting. Shanghai VW’s Jiang Wei discussed an investigation of headlamp fogging solutions, and  PATAC’s Huang Yi closed the session with a speech on innovative OLED applications in automotive lighting

Session 2, chaired by Wolfgang Huhn, focused on the technologies in lighting as a lever of safety and styling. The session started with Rainer Neumann who overviewed opportunities for improvement in light performance. Shanghai Koito presented their achievements on ADB & matrix lighting technology. Then Claude Penn gave a lecture on the successful AL e-Light achievements, followed by Frank Huber who presented the LED systems and the matrix revolution.
Kiyotaka Mochizuki from Koito spoke on the trend of lighting considering styling and safety, and Mobis’ Taewon Lee closed the session with a speech on LED lighting technologies.

An interesting keynote on ELS, a new training school in lighting, by Jean-Paul Ravier opened the second day.

Session 3, chaired by François Bedu , centred on advanced LED technologies, with the lectures of  Valeo’s China regional R&D boss Stephane Thery, Lumileds’ head of automotive R&D Peter Stolk, Osram's SSL VP and General Manager  Claus Allgeier, and Everlight’s R&D manager Johhny Lu.

Session 4 was chaired by GTB President Geoff Draper, and got started with a presentation from him reviewing the conclusions reached so far and to discuss a course of action that could become an important step toward harmonised technical requirements. Then He Peng presented the priorities of the Vehicle Manufacturers  (CAAM) followed by an interesting lecture of Prof. Dr. Yandan Lin on the international collaboration of  research on the performance-based evaluation system for headlamps.

Session 5 was chaired by Dr. Claus Allgeier and focused in a first part on lenses with lectures from Docter Optics' Dr. Jan Hamkens, who presented new approaches for design, style, performance, and safety; and from Mr. Wenqing Liang, of Bicom Optics, on high-precision molding, and in a second part on new electronic drivers architectures with Keboda's Jun Zhao and NXP's Dr. Prem Sharma.

Session 6, chaired by Michael Meyer, was about measurements. It got under way with Dr. Thomas Reiners from LMT, who sketched in his lecture the challenges which come along with the spatial measurement of time modulated signals. This was followed by a talk by Mentor Graphics' Boris Marovic on new possibilities of simulation tools for identifying condensation and icing problems at the earliest possible stage. Then came a lecture by Synopsys' Thorsten Shupp outlining the importance of luminance analysis for signal lamps. The session was rounded out by Julien Miller from Optis-World, who discussed virtual prototyping.
