Wanted: Simple Light Performance Test PDF Print E-mail
Monday, 19 July 2010
In my last editorial, I emphasised the lack of communication on automotive lighting and the resulting decrease of users' interest for this matter. One possible lever to increase interest could be the assessment of lighting performances.

At DVN 2010 workshop in May in Paris, Michael Hamm presented an interesting lecture on the status of different assessments:
- from journalists and mainly Autobild in Germany and Consumer Report in North America with 5 simple rating scales: Excellent – Very Good – Good – Fair – Poor
- from EuroNcap initiative with unbelievable criteria not all understandable after around twenty meetings of plenty of experts..

At this workshop, many of us quoted the EuroNcap assessment method as “too long and complicated” and suggested to work on a simpler assessment approach. Some experts are working in this direction, using a basic but rigorous approach, and DVN is totally open and available to work with them and to communicate on their work.
The resulting performance assessment method, once adopted by our industry, could be a good lever to communicate and to advertise on lighting.

To succeed, we have to inspire ourselves with the simplicity of the rating scale of journalists. In our opinion, journalists' assessment on car lighting always lacks rigor but it is simple and understandable by the user. Car makers react to these assessments and consider them as important because they impregnate drivers' minds and purchasing decisions.

Action is needed in this direction. More information will be presented in next newsletters. Meanwhile, what are your ideas? We're listening!

 Sincerely yours

 
J.W. Speaker's Popovic on LED Headlamps R&D Director Shares His Company's Perspective PDF Print E-mail
Monday, 05 April 2010

By Daniel Stern 

J.W. Speaker, a 50-year-old manufacturer based in Germantown, Wisconsin, USA, have introduced a multiple-optic full-LED high/low beam headlamp designed to the standard SAE 7-inch (180mm) round dimensions used on numerous passenger, cargo, military, and off-road vehicles as well as motorcycles in North America, Great Britain, Australia, Japan, and elsewhere. It has a heat sinking die cast aluminum housing, a hardened glass front cover lens, a built-in fan for thermal management, and four optical elements visible from the front giving a highly technical appearance. The large upper projector lens handles output from a 1x4 emitter array equipped with a stair step "Z-beam" cutoff shield. This optical stack produces the high-intensity hot spot and forms the low beam cutoff. The D-shaped edgewise cylindrical lamps, each in front of its own emitter, provide beam width and homogeneity. The lower projector is for the high beam hot spot, and has a 1x4 emitter without cutoff shield. One optical version of the lamp is certified as complying with SAE requirements for the NAFTA market and is also type approved to ECE regulations for use throughout the rest of the world in right-hand traffic. A second optical version of the lamp has a mirror-image cutoff shield in the low beam optical stack, to produce a left-traffic beam; it is type approved to ECE regulations. 12v and 24v operation is possible.

VISION 2010 Call for Papers Closes PDF Print E-mail
Monday, 29 March 2010
The biennial VISION congress on automotive lighting and driver assistance, organised by Driving Vision News founder and chief Hector Fratty under the auspices of the French Society of Automotive Engineers (SIA), will be held this coming October 6-7 at Versailles, France.

The congress consists of three parts:

  • 30 lectures of twenty minutes each, spanning over two days
  • An exhibition area devoted to lighting equipments and services, with a particular focus on Tier 2 products and services. Lighting suppliers have long lacked a motor show or forum where they can exhibit their products, and VISION has the ambition to become such a place.
  • Night test ride-and-drives on a 5-km private test track, with demonstrations of the latest technology and implementation of adaptive lighting, driver assistance, and LED headlamps. The test track will have three different segments: the first for night test drive, the second for low speed night drive (pedestrian and obstacle detection), and the third for special lighting and driver assistance systems.

This year, the Steering Committee received 60 abstracts, an increase of more than 50% over 2008. This huge number of abstracts gives a great responsibility to the Committee to select the 30 best lectures according to four criteria: innovation level, industrial potentiality, relevance of scientific elements, and importance of the subject for safety improvement.
The lighting abstracts show the priority of our industry to develop and improve intelligent lighting systems, Xenon 35- and 25-watt systems, and LED technology (including making automotive lighting more affordable). The driver assistance abstracts emphasise the development of DAS mainly in relationship with safety—visibility and pedestrian detection. Clearly, the link between lighting and driver assistance is becoming stronger as these two aspects of vehicle safety are increasingly combined into comprehensive driver perception aid and enhancement systems.

Increasing Promotion of Lighting Driving Assistance features PDF Print E-mail
Monday, 12 July 2010
After last week's DVN summary of the survey from Frost and Sullivan published in May 2010 about the future of Driver Assistance features, Driving Vision News received a large feedback:
- Many commenters mentioned the forecast penetration of advanced safety features to a new high in North America but also in Europe.
From 4.5 million units in 2009 to 17 million in 2016 in North America
From 3.3 million in 2009 to 12 million units in Europe
It is a huge growth which can change the future of companies involved in DA.
- Others commented on the positive influence of legislation. This lever has to be considered. We have today affordable features which are able to improve safety and we have to promote regulations to mandate them.
- Still other comments were about technologies which are not sufficiently known by vehicle owners, like blind spot detection, collision warning, or traffic sign recognition. For example only 18% know of blind spot detection or collision warning.
Companies involved in such technologies have to be very creative to introduce them to end users in a simple attractive way, easy to understand and use. If we can be satisfied that 41% of vehicle owners pretend knowing adaptive lighting technologies (even if the definition is not clear), then a big job remains to extend these percentages to all safety features.

Sincerely yours
