Two weeks after the SAE SHOW at Detroit, Driving Vision News publish a report which is meant for the lighting community, for experts who were not present or experts who attended the congress but missed some important lectures.
The main lectures which we selected in this report can be classified in 2 categories:
– On LEDs, Lawrence Rice from Osram Sylvania and Rainer Neumann from Visteon presented future LED headlamps. Rice presents a headlamp with one LED module producing the same performace as a halogen bulb, and Neumann shows a headlamp with low beam of 135mm × 50mm with performance not far off the Xenon benchmark.
– On Xenon 25w, Jean-Sebastien Straetmans from Philips presents the possibilities of an integrated module and the benefits on size, weight and consumption saving.
– On front end structure, Ankit Garg from GE India shows a novel energy absorber concept to improve the pedestrian safety, low speed vehicle damageability performance and replacement cost reduction.
2. Studies and Surveys
– TU-Darmstadt university was very present at Detroit with 2 lectures.
One was about the evaluation of headlamp cleaning system from lab and field measurements. Stefan Soellner showed the first part of this evaluation (the second part will be presented at VISION congress this coming October in France).
The second lecture, from Nils Haferkemper, 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 everywhere to efficiently gather relevant data about headlamp patterns, and the second showing 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 , in a time where so many technologies are arriving in high beam assistant or adaptive lighting, we had only one lecture. This was from Honda R&D’s Haruhiko Nishiguchi about Blind Spot Detection and the image processing method for easier perception of speed from the camera image.
All these lectures are detailed with a lot of explanations, snapshots and figures.
A strong and new point in SAE 2010 congress DVN report is that at the end of each lecture, DVN interview the speaker about his lecture.
