The basic idea behind interior lighting was to improve the feel-good atmosphere in the vehicle.
In fact, static or dynamic lighting effects can create a pleasant atmosphere in the interior and thus have a positive influence on the driver's concentration. Studies show that low color temperatures tend to increase the feeling of comfort, while higher temperatures improve alertness – both of which are crucial factors for road safety.
Ambient lighting also enhances the interior appearance during nighttime driving.
But modern ambient lighting is more than that. In addition to targeted lighting effects, for example to prevent fatigue, safety-related warning signals can be displayed visually so that even in a noisy vehicle interior (loud music, a fully occupied vehicle with everyone talking, etc.), a warning message cannot be overlooked. Lighting effects can therefore be a functional component of safety-oriented vehicle systems.

The Preh Advanced Light Concept opens up new dimensions in vehicle interiors. Here, light guides combined with special light sources and control electronics create impressive 3D depth effects – without the use of displays. This approach offers new possibilities for brand customization and user guidance in the interior, especially against the backdrop of the increasing need for differentiation in vehicle interior design.
The Preh Advanced Light Concept is based not only on design aspects, but also on technical precision and efficient series integration.
Another innovative leap forward in ambient lighting is the implementation of Matrix LED arrangements in vehicle interiors. Unlike classic, linear LED solutions, Matrix LEDs enable flat, segmentable lighting scenarios. These regularly arranged LED structures offer flexible and interactive design of lighting zones – ideal for individual interior lighting design.
However, integrating such matrix systems is complex. Multi-layer, three-dimensionally shaped circuit boards are required if they are to be used in door panels or under curved dashboard surfaces, for example. At the same time, the LEDs within the matrix must be controlled individually by means of a clocked BUS system – while ensuring completely homogeneous color rendering across the entire surface.
Such challenges require optimal coordination of electronics and mechanics in the most confined of spaces. Only through optimized thermal management and highly integrated control electronics can cost-efficient, production-ready solutions be developed. This makes the ability to seamlessly integrate electronics and mechanics a key competence in the development of modern lighting systems.
