Xenon (HID) technology is one of the mile-stones in developing process of car lighting. The first step was to combine this technology with free-form reflector technology. The result was a high performance dipped beam beam-pattern with three times more light output compared to a halogen system. The next step of improvement is “Bi-Xenon”. It makes sense to use the enormous light output of a Xenon light source for two light functions (Main beam and dipped beam) in a single pocket headlamp system. This leads to new lighting performance and design freedom in headlamp technology. In this paper the technological aspects of system realization will be described. New solutions in lighting strategy including modern actuators which handle optical elements to switch between two light functions had to be found.

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.
