Proceedings of the 11th International Symposium on Automotive Lighting (ISAL)

It is a pleasure to present you the proceedings of the 11th International Symposium on Automotive Lighting, which takes place in Darmstadt on September 28-30, 2015. This conference is the document of a series of successful conferences since the first PAL-conference in 1995 and shows the latest innovative potentials of the automotive industry in the application of lighting technologies. These proceedings result from the work of a lot of experts in the automotive and optical industry, administrative bodies, research institutes and universities. It summarizes the findings of more than 200 authors and co-authors and gives a scope of their expectations for the future. In 2015, the ISAL Steering Board could identify the following focus topics: • The blue laser technology with stable phosphor systems giving the highest luminance for the development of the new high beam booster systems with very small size and apertures • Pixel-light headlamps with two dimensional LED-arrays or glare-free high beam with vertical segments and driver assistance with the interaction between light sources, cameras, digital image processing and headlamp systems • LED technology generally and the new high-current and high luminance white LEDs are promising solutions for innovative headlamp developments • Energy efficiency, CO2 reduction and methods for their realization • Traffic accident analysis, traffic and automobile regulations • Optical measurement, human eye physiology and mesopic research. Besides the modern LED-headlamp developments for higher class vehicles with a luminous flux of about 1100 lm, some headlamps with LED low beam have been demonstrated performing a luminous flux of 600-650 lm on the road using about 11-13 W electrical power. Parallel to the development of LED-array for pixel light headlamps, other technologies like LCD and DMD-systems are subjects of intensive research in order to reach a traffic space resolution of more than 10,000 pixels. This development must be hand in hand with the improvement of the image processing like camera and sensor technology as well as efficient embedded algorithms. Quality of sensors, image processing and sensor fusion will determine the future of driver assistance. During ISAL 2015, we will have a podium discussion on the test strategy and the acceptance tests for the ADB-headlamps with some contributions of GTB, universities and other institutions. The aim of this podium discussion is to analyze the advantages and some deficits of the current ADB-systems in order to have an acceptance on the American market. We wish you a very informative and successful ISAL 2015 in Darmstadt. We hope that this year’s event and these proceedings will give you inspiration and motivation for your work during the next 24 months. Yours sincerely, Prof. Dr.-Ing. habil. Tran Quoc Khan
