HELIOS is a program for calculation, simulation and analysis of lighting problems expecially designed for car lighting technologies. Base is an “experiment” in which optical elements and theire features are described. Example: The reflector is defind by CAD-data and the surface is reflective. The result of simulation will be a light distribution. The performance has to be analysed. The LDE gives us the possibility to analyse light distribution strategies before calculation of the reflector surface itself. It is a “virtual light world”. This reduces developing time and costs and gives a help to find the best technical solution for complex illumination problems.

Modern cars require innovative technical solutions in several areas. The headlamp systems of today are designed especially to pass legal requirements all over the world. Since 3 years age continued discussion was started to improve the quality of light distributions for headlamp systems with new regulations. The project is called AFS (Advanced Front Lighting Systems) and it relied to dynamic changing of light distributions depending of traffic area and condition. The legislation procedure for AFS will not be closed before the year of 2003. Up to this time we think about improvement of lighting quality by using light functions which can be realized within the legal legislation procedures of today. In our paper we will describe a new light function called Static Banding Light. The target is to add to the well known dipped beam light distribution in Xenonor Halogen-technology a banding light function which gives light in areas which normally are not reached by a standard dipped beam.
