The 82nd Geneva motor show gave display to a wide array of vibrant concepts and production models, from evolutions of electric and hybrid drive to a radical Bentley SUV and the rebirth of an icon in Peugeot's 208 GTi concept; manufacturers were certainly playing to their strengths. The show was a nice, easy introduction to the year. It was less intense than Frankfurt, less chaotic than Paris, less American than Detroit. It was the start of spring on neutral ground for every manufacturer, and gave a preview of the cars we can look forward to driving in the coming months.

This past January, we held a DVN Workshop in North America for the first time. After Stuttgart in 2009 and Paris in 2010 and 2011, the 2012 DVN workshop was held in Rochester, near Detroit, a wonderful location, during the North American International Auto Show. The event was a smashing success, well attended by 125 experts from all sectors of the lighting and driver assistance community. There were researchers, practitioners, automakers, tier-1 and -2 suppliers, consultants, regulators, and academics. In a very active and full day, we had lectures and presentations, round-table panel discussions, display booths, and a great deal of high-level discussion and exchange of ideas.

The 114 pages of this report will brief you on the exchange of ideas, plans, innovations, and perspectives from automakers, researchers, regulators, academics, practitioners, and Tier-1 and -2 suppliers in the automotive lighting industry. In the first chapter, we précis lectures from such experts as ValeoSylvania's Jerry Dittrich and John Orisich, Osram-Sylvania's D. Hulick, D. Vanderhaeghen from Philips, Audi's Wolfgang Huhn, Visteon's Rainer Neumann, Mike Larsen from GM, Mahendra Dassanayake of Ford, AL's Ernst Olaf Rosenhahn, Michael Flannagan from UMTRI, and RPI-LRC's John Bullough.

The second chapter presents the four round-table panel discussions, including presentations of panel chairmen Ingolf Schneider (Opel), Kamislav Fadel (AL), Thorsten Warwel (Ford), and Dennis Novack (Chrysler):

• LEDs: Limiting factors and main challenges in US market
• Will LED lighting really save energy?
• Does LED Intelligent Lighting improve safety?
• How LED can contribute to make lighting more attractive?

Moreover, profiles of 25 T1 and T2 lighting companies present at the workshop are presented with contact information for their experts and managers and a guide to how lighting fits into their strategy. Among these are:
Tier 1 : AL, Grote, Hella, Koito, NAL, Odelo, SL Corp, J.W. Speaker,  Valeo, and Visteon.
Light source suppliers : Osram, Philips, GE, Nichia, and Seoul semiconductor.
Plastic/coating suppliers : Bayer, Sabic, GXC and DBM-reflex .
Electronics providers : Freudenberg, Mitsubishi Electric, Osram, and Philips.
Simulation software developers : Brandenburg, and Delvis.
Components suppliers : CCI, Docter Optics, and Sea Link.
Mechatronics developers : AML Systems and Sonceboz

At the end of the report, the author presents pictures of the main players of car makers and Tier 1 & 2 lighting suppliers talking together at the DVN workshop.

The inexorable march towards LED will have implications for all market participants, requiring alignment of products, engineering skills, and capacities. How and when these new LED technologies will impact the US automotive market was the central question which has been discussed among automotive lighting experts from all round the world.

2012's North American International Auto Show was different to 2011's in a very substantial way: Last year's was revolutionary, while this year's was mostly evolutionary.  This is no great surprise; the 2011 show came after three completely awful years for the auto industry as a whole. Strong signs of life returned with a vengeance for 2011, and we were delighted to report on American automakers' notable discovery of lighting technology and technique as much more than just a necessary expenditure to comply with prevailing regulations.

The 64th IAA, International Auto Show, was very different from the 2010 and 2009 shows. More than during the 2010 Mondial in Paris, the products shown and the luxurious exhibition booths emphasise a renewed optimism this year with a welcome return of some dreamy concept and exciting production cars. From simple styling studies to full-on predictions of forthcoming production models, the numerous innovative prototypes at Frankfurt showed renewed confidence within the automotive industry. In this report, we focus on this new, brighter situation and present all the new cars exhibited in Frankfort.

Concept cars with the most innovative lighting include: Audi A2 concept, Mercedes-Benz F125, BMW i3 and i8, Alfa Romeo 4C, Citroën Tubik, Ford's striking Evos, Peugeot’s HX1 and 508 RXH, Hyundai's CUR3, Renault's Frendzy, Volvo’s Concept You, Seat's IBL, Toyota’s secondgeneration FX-86 concept, Chevrolet’s Miray, Kia’s GT, SsangYong's X1V, Subaru’s BRZ, and Mitsubishi’s PX-MiEV.

This report is written primarily for automotive lighting experts who were not present at SAE 2011 World Congress or who may have missed important lectures there. In 30 pages, we summarize and analyze the main presentations.
This year there was relatively sparse participation from Europe and Japan, which was a pity. But about 100 people attended—some standing for lack of enough chairs—which is a big increase over the past two years and shows renewed genuine interest in the subject of vehicular lighting and related matters.

The lectures covered LED and HID technological developments and in-depth survey studies of lighting-related safety performance and human factors issues.

Lawrence Rice from Osram presented a clear, interesting lecture about optical design facts and factors with LED headlamps, and Josef Schug from Philips gave a detailed lecture about current strategies and coming trends in heat sinking and thermal stackup with LEDs in headlamps. Joachim Reill of Osram Opto Semiconductors presented a technical discussion of some non-obvious bad effects of heat on LEDs, and how these can be mitigated. Rainer Neumann from Visteon presented with his usual charisma a lecture (and movie!) on 25w HID headlamps. Another paper on the topic of 25w Xenon was presented by Helmut Tiesler-Wittig from Philips.

John Bullough from Rensselaer Polytechnic Institute's Lighting Research Center presented two lectures, one about U.S. concerns over headlamp glare and visibility—which point up US drivers' and news reporters' poor understanding of lighting. Bullough's second lecture showed the great effects on discomfort glare of the background luminance of a glare source such as a headlamp.

The exhibition was very weak in lighting with few small companies as DMC (Thermoset producer) and Hamsar (aftermarket LED headlamps) presenting their products. Some concept cars already presented at NAIAS or Geneva were shown. This is in contrast to the much larger lighting presence at the SAE expo in the late 1990s and early 2000s, when many major Tier-1 and Tier-2 lighting suppliers were present. On the other hand, this year's lighting presence and interest at both the congress and expo was markedly stronger than last year's or 2009's, so we can look forward to (and work toward) that trend continuing.

2011’s Geneva auto show was very different from those of the last 2 last years. The atmosphere was positive this year with a welcome return of some real supercars and concept cars. From simple styling studies to full-on predictions of forthcoming production models, the prototypes were numerous at Geneva. They were innovative and show renewed confidence within the automotive industry.

Just last year, things looked grim. It was difficult to find much basis for optimism in the way of lighting or driver assistance innovation in the American market. There were dribs and drabs here and there, but they were mostly employed as marketeering hooks, considered on par with a new paint colour. What a difference a year makes!

VISION 2010 report PDF Print E-mail

This report is written primarily for automotive lighting and DA experts who were not present at VISION 2010 or who may have missed important lectures there. In 97 pages, we precise and analyse the main presentations.

This year, VISION's lectures, posters, night-drive demonstrations and booths combined to make an exceptional congress on new technologies with emphasis on the unprecedented speed and preoliferation of new and newly-mature technologies and techniques. More than 250 people attended.
The lectures cover:
- LED technology and its continuing improvements in optics, thermics, architecture, and power savings.
- Adaptive light systems, new technologies moving very fast with the arrival of cameras to implement intelligent automatic beam selection with the several corresponding adaptive systems, high beam assistant, horizontal and vertical adaptive cut-offs, glare free high beam.
- Technologies combining LED and adaptive light including LED arrays to produce AFS, matrix-beam systems, and spot marking light functions.
- Xenon technology and its constant progress; the great potential of new 25w Xenon systems to improve safety and reduce power consumption in comparison to Halogen
- Environmental aspects, within which the concept of the ?wattage index? shows that for average cars and speeds, good and safe Xenon/LED lighting can be provided that generates only 1g CO2/km saving more than 2g CO2/km vs halogen.

We were impressed by the charismatic presentations of Michael Hamm and Rainer Neumann, the fantastic slides and video of Michael Kleinkes, Thomas Manth and Stephan Berlitz and the technical lectures of Olivier Barthomeuf, Y.Kasai, B.Reiss, Steffan Sollner, and Georg Schneider, amongst others.

In the second part of the report, we present the drive night tests, with the main strong points:
- Performance differential with Xenon or LED is such that driving at night in bad weather conditions with legal halogen headlamps can legitimately be considered dangerous. Augmented, high-feature halogen lights with motorway and static bending functions improve the safety, but these complements are not enough.
- Xenon headlamps make night driving safe even in bad weather.
- LED headlamps have evolved significantly since the 2008 demonstration, and can produce a good light which permits safe driving at night in bad weather, with now equal Xenon performance in terms of beam flux and coverage.
- Automatic beam selection is at long last a dependable, high-performance feature which permits maximum possible use of the high beam.
The authors close the report with pictures of the VISION 2010 lighting community gathering and exchanging ideas about automotive lighting.
