I will be attending SAE 2010 World Congress at Cobo, Detroit, starting today on April 13th and even if there are fewer exhibitors and lectures than last year, the SAE organisers predict a stronger focus on innovation.
Lighting lectures will be focused in 2 sessions on Tuesday April 13.
I’m expecting nice papers.  
 
I have selected five very interesting lectures, based on the subject and the speaker:  

Photometric Measurements of Headlamps Exposed to Dirt from TUD Darmstadt
I personally followed this study and was deeply impressed by the job done in the field and its high level of accuracy.  

Xenon 25W from Philips
Xenon 25 W is one of the most important current innovations and we are all excited to hear the news from Philips.

Real-World Measurement of Headlamp illumination from LRC, Rensselaer Polytechnic Institute
I have heard many lectures of John Bullough, every time with a great interest.

Headlight with Single LED Module from Osram Sylvania:
LED is the innovation of these last 5 years and we expect interesting information on it  

Tri-Functional Headlamp System with Low Power Consumption from Visteon:
Rainer Neumann is one among the few experts I know whose lectures always deliver a pleasant technical surprise with a lot of charisma.

DVN will publish a detailed report of this SAE 2010 World Congress on Tuesday, April 27. It will not only comment the most interesting lectures but also highlight the outstanding features exhibited in the booth area by Tier 1 and Tier 2 lighting suppliers.

Sincerely

Last week, we published our latest in-depth technical report covering the state of the art and market in LED headlamps. We think this is probably our most significant report since our inception two years ago.
Thank you for the numerous comments DVN received. I was very surprised and pleased by your congratulations and your support but also by the critics and the suggestions which are strongly helping me.

Several critics were about missing information on optics, electronics and mainly on products in development. There are today many products from all the lighting suppliers in development but the target of DVN is not to publish confidential scoops but to publish information able to help the lighting community.

And because in the next months several new LED headlamps will be launched on the market, following your suggestions, DVN plans to publish an updated report at the end of the year.
Driving Vision works for the lighting community and can’t exist without the help of the lighting players who are in the field. Please continue to help me, giving information, non confidential information but information  which allow Driving Vision news to share with you the new technologies and to promote automotive lighting in a time when CO2 reduction interests the automotive community.
Thank you again for your communication, and from the whole DVN team to the greater lighting community, have a happy and prosperous new season!
Sincerely

 
Jean-Paul Charret : “The better remains to come in Front Lighting Technologies” PDF Print E-mail
Monday, 22 March 2010
Style and Performance have always been two major drivers in the evolution of headlamp technology
We can say that we are entering into a new era in Lighting Systems with two technology breakthroughs: first with the introduction of Adaptive Driving Beam and second with the multiplication of LED Front Lighting design.

After Xenon in the early 90’s and AFS in the first decade of the 2000s, the introduction of Adaptive Driving Beam this year will clearly be a major step towards a full visibility “day time like” system allowing to drive all the time like in High Beam. We can affirm that performance will be at the highest level ever reached.
The first LED headlamps introduced on the Lexus LS 600, Audi R8 and Cadillac Escalade have been designed with a very conventional style to demonstrate the feasibility of the technology without fully exploiting its potential.

We are now entering a second step with LED Front Lighting, where the advantages are surfacing. Important Style evolution, like on the new Audi A8 with dotted aspect, or lower electrical consumption on Electrical or Hybrid cars, like on the Toyota Prius and some others which will appear this year.

But the best remains to come, with designs which will cumulate all the known benefits of LED Front Lighting:
Styling freedom without the constraints of designing a conventional Halogen or Xenon system; scalability of the design; differentiating versions without compromising the overall line of the vehicle; full flexibility in terms of performance and power consumption; adapting the lighting to all events happening to the car on the road ; lighter and less complex products with the LED’s increased efficiency allowing passive thermal dissipation without bulky heat sink.

The next 3-4 years will be another exciting challenge for the entire lighting community for the full benefit of the end users in term of safety and innovative designs.

Sincerely yours

New DVN In-Depth Report Released: LED Headlamps PDF Print E-mail
Monday, 29 March 2010
Driving Vision News announces this week our latest detailed technical report, on the state of the art and market in LED Headlamps. I’m especially proud of this report because it is a synthesis of the very last status of the art and trends as they appear not only to me but also in the eyes of the best world known experts in this field. LEDs are appealing and key to the future of front lighting.

The report has been put together with the latest technical information available from our members who are at the leading edge of LED technology and technique. The state of the art is highlighted with the numerous advantages of LEDs over traditional light sources but also the specific related challenges. There are more than 150 illustrations, curves, plots, and data sheets to present comprehensively useful information about LEDs in their newest automotive application.

We have worked hard to make this report a reference standard for our professional community of car makers, tier 1 & 2 suppliers, and research groups. It assembles all needed strategic information on technology, luminous performances, and market prices with a vision of the future of LEDs extrapolated towards 2015 and 2020, and compared with Xenon and Halogen light sources.

After describing in the first part the technologies involved in the latest LED headlamps, this report covers in its second part the offer and market strategies of the main leading global automotive LED suppliers. In its third part, detailed illustrations and comments are given on 10 LED headlamps equipping production car models as well as two modular universal-fitment LED headlamps, with detailed description of where the progress is most prominent. To point the way forward and spark the imagination, we present more than 20 concept car models featuring LED lighting.

The benefits and weaknesses of LED headlamps are discussed, and we offer a roadmap of LED headlamp development and evolution. Finally, the future of LED headlamps is described as seen through the eyes of this author and—in my faithful opinion—through the eyes of some of the best automotive lighting experts in the world. We eagerly and earnestly await your feedback!

2010 International Geneva Motor Show PDF Print E-mail
Monday, 15 March 2010

Driving Vision News is publishing this week its report on the March 2010 Geneva Motor Show. For those who could not attend the show, you will find 45 pages presenting all the new concept and production cars exhibited in Geneva, with our usual zoom on their lighting equipment in relation with styling, safety and energy consumption.

This 2010's Geneva auto show was centred around one strong priority: the reduction of energy consumption.  Alternative power train technologies dominated the fair. Green being the key word,  Automakers have focused their communication on electric vehicles and power consumption reduction rather than on the comfort and safety benefits to be derived from lighting and DA technologies.
Main innovative concept cars shown:
• Citroën DS High Rider presented in an impressive booth
• Mercedes F800 which unveils MB's future styling direction
• Opel Flextreme which confirms the high level of GM/Opel innovation expertise in green cars
• SR1 and 5byPeugeot which preview Peugeot’s new flagship
• Fluence ZE and other concept cars which emphasise the involvement of Renault in electric cars
Main innovative production cars launched:
• Audi A1 and A8 which display the constant innovative spirit of Audi
• Ford Focus demonstrating Ford's strong ambition
• Nissan Leaf with innovative LED headlamp styling
• Toyota Auris with high-tech headlamp and dual-function fog/DRL lights
• Volvo S60 with pedestrian detection technology and innovative LED rear lamps

The 4 main takeaway points are:

• Geneva 2010 was totally focused on green cars
• Green promotion drowns out communication on lighting and driver assistance
• Front and rear of the car are increasingly the main areas of styling innovation and differentiation
• Many interesting production and concept cars were shown
 
I hope you will enjoy reading this report
