Interactive Lab Assistant: Modern Automotive Light Systems - Xenon, LED and DRL

The lighting system in a vehicle is one of the most critical systems in terms of safety. It ensures that the driver of the vehicle can quickly observe events in the surroundings, even when it is dark, thus enabling safe and careful driving. Over the course of the last few years, lighting systems in vehicles have undergone important developments. Halogen lights are losing their importance and are increasingly being superseded by xenon and LED systems. These not only provide good lighting, but allow dynamic lighting functions to be implemented which greatly increase safety in traffic. However, front headlights are not only a key part of the safety aspect, they also play a key role in defining the look of a vehicle – in particular the daylight driving lights, which many well known manufacturers are now putting to use.

The training system "Modern lighting systems in vehicles – Xenon lights, LEDs and daylight driving lights" consists of various modular panels, which offer many possibilities for interaction and practical working with the CO3221 system. Furthermore, the accompanying multimedia course uses numerous animations to make the theory easily understandable and to present it in an attractive way. The experiments included interact with the hardware and thus ensure an in-depth and well-grounded understanding of the system, which can be directly applied in practice at vehicle repair workshops. Thanks to the built-in fault-finding system, various faults in the system can be activated, which also ensures the acquisition of essential diagnostic skills.

The hardware allows the following practical experiments to be carried out:

• Analysis of the system for automatic range adjustment (self-levelling) systems
• Measurements on a LIN bus
• Measurement of voltage and current on lighting components via 4-mm safety sockets
• Measurements on the servo motor for the automatic range adjustment system via 4-mm safety sockets
• Incorporation of the lighting system into an overall lighting system for the vehicle controlled via a CAN bus
• Activation of various faults to create intentional breakdowns in the system

Please note that this system can be incorporated into the overall CAN-bus lighting system from Lucas-Nülle (ALC 1.6).
