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!

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.

2010’s Paris auto show was centred around one strong priority: the reduction of energy consumption.  Alternative powertrain technologies dominated the fair. Automakers focused their communication on electric vehicles and energy consumption reduction rather than on the safety benefit to be derived from lighting and DA technologies.
In this report, Driving Vision News presents all the new cars exhibited in Paris and their lighting equipment in relation with styling, safety and energy consumption reduction.

DVN organised a workshop with almost all European car makers and tier-1 lighting suppliers.
Some DVN Gold members have regretted their absence from the intensive event, so I am glad to present today a detailed report of this workshop.

You will discover in this report the lectures presented by Dr Huhn (Audi), Benoist Fleury (Valeo), Dr Schäfer (Philips), Dr Dorissen Hella,Lex  Krzyzanoswki (LSS) and Dr Hamm (AL). You'll also find coverage of the three round table discussions on Xenon, LED and how to sell the advanced headlamps.

At the workshop, divergent opinion was apparent but there was also some consensus amongst the participants. Many questions on timing introduction of LED mass production remain without firm answers.

The four most important challenges are:

LED is the technology of the future…but when?
its introduction timing is not clear:
around five years for one group, more than 10 years for the second group?

Communication is the key point to increase take rate of Xenon then LED.

but how to do a common communication?
What kind of communication: Dealers, Video, Internet?

We have to consider the cost of the LED system with styling constraints.

but price/Timing of LED system is not clear

We have to succeed standardization but how?

on LED chip and module evolution, binning, connection, standardisation, and specifications.

For each subject and each question, you'll find not just coverage, but also comentary.
In spite of the many questions without pat answers, we present a lot of information which will help you to better know the present state of the challenges and benefits of new lighting technologies.

About the sessions
The main lectures which we selected in this report can be classified in 2 categories

Innovation

- LED headlamps: Lawrence Rice from Osram Sylvania  and Rainer Neumann from Visteon  presented prototypes and concepts. Lawrence demonstrated a hold-in-the-hand sized with one LED module producing  the same performance as a larger halogen headlamp and Rainer showed an LED headlamp with low beam frontal area of 135 mm x 50mm, giving performances not too far off the  Xenon  benchmark.
- Xenon 25W: Jean-Sebastien Straetmans from Philips presented the possibilities of a compact, unitised bulb-ignitor-ballast module with benefit on size, weight, packaging and power saving.
- Front end structure: Ankit Garg from GE India presented a novel energy absorber concept to improve the pedestrian safety, low speed vehicle damageability and repair cost.

 Studies and Surveys

- DUT Darmstadt was very present at Detroit with 2 lectures:
One on the evaluation of headlamp cleaning system performance from lab and field measurements. Stefan Soellner showed the first part of this evaluation with very interesting information on soiling and cleaning; the second part will be presented at VISION congress, this October in France). The second lecture was from Nils Haferkemper which emphasizes the positive influence of LED DRL feature on the conspicuity of motorcycles.

- John Bullough from Rensselaer Polytechnic Institute presented 2 lectures, one about the development of a system that can be mounted along an intersection, curve or parking facility to efficiently gather relevant data about headlamp patterns and aim that might relate to glare or visibility. The result suggests that if vehicle headlamps were better aimed, that the amount of light reaching oncoming driver’s eyes would be more consistent.
John’s second lecture showed the large influence of ambient illuminance from urban areas on the visibility of relevant targets, and show advantages of different headlamp for different target locations where pedestrians might be encountered.

In driver assistance, despite so many technologies arriving in high beam assistant or adaptive lighting, we had only one lecture from Honda R&D, Haruhiko Nishiguchi about Blind Spot Detection and a novel image processing method for more accurate  perception of speed of adjacent vehicles seen in the side-view camera image.
All these lectures are detailed with a lot of explanations, snapshots and figures.

Interviews
For the first time in this report, at the end of each lecture, we feature an exclusive Q&A with the presenter about some points of his lecture or about analysis of his vision of the future.

Exhibition and awards

Few systems detected on presented close the report with awards of companies and award for experts.

North Americans, producers and consumers alike, tend not to have much interest in lighting or driver assistance. In contrast to motor shows in Europe and Asia, there was almost no substantial promotion of driver assistance or lighting technology, nor of energy-saving technology.

Largely the show was populated with Japanese automakers. Nevertheless, there were two points of focal interest for us:
1) Large number of new Japanese cars, production and concepts
2) Presence of the primary Japanese lighting suppliers and most of worldwide driver assistance providers.

With so many new Japanese models, we glean a better sense of the forthcoming trends in the Japanese domestic market as well as the direction of Japanese cars and suppliers in markets worldwide. We see strong priority on the reduction of energy consumption, which means for lighting suppliers wattage reduction, weight reduction and packaging reduction. The link between automakers’ environmental goals and lighting technology and styling is particularly emphasized.
