Today's requests from automotive manufacturers for innovative designs for signal and interior lamps are driven by three typical tasks: Saving space and depth in the lamp for easier and cost saving integration in the body construction. Lamp thickness should be reduced to a technically achievable minimum. A homogeneous illumination needs to be realized with a minimum number of emitters (particular with LED). Line design should be supported by reliable technologies, enabling stylists to develop contour-driven designs. All these demands can be supported by “Solid Light Guide Optics”. In this optical concept a solid light guide with the basic geometry of a tube receives the light from a light source (bulb or LED) directly, or via an additional flexible light guide. The rays are transmitted in the circular solid light guide by total internal reflection and will be also coupled out partly with the aid of prisms or structures on the rear side of the longitudinal axis of the guide.

When it comes to innovations for lighting in the front of motor vehicles, mostly the road illuminating systems are mentioned. However, in addition to the progress in the “real beam tasks” with swiveling headlamps, AFS etc, new potential for the “pure” signal functions has also arisen in recent years. Looking at the safety requirements for front lighting of the vehicle with the task “to be seen”, it becomes obvious that the mandatory signals Direction Indicator and Position Light should be complemented during the day via the Daytime Running Light (DRL). By displaying the position of a car (by day and night) and indicating a change of direction with the Turn Signal, complete and intuitive recognition of the vehicle-front will be realized.
