Some 50% of drivers feel stressed when driving in poor lighting conditions. The better the road ahead is illuminated, the less stressful they are: good lighting is the best night vision aid. HELLA Group has been setting lighting milestones ever since the very first automobiles were invented. It is consistently highly innovative in the way it approaches the development of lighting products and systems. Although our focus is primarily on enhancing driver comfort and safety, the fact that our lighting products are also attractive in appearance means that car manufacturers can come up with specific vehicle designs and fulfil their strategies.

One of the first lighting assistance systems was the dynamic cornering light, introduced in 2003. In this system, the light modules rotate according to the steering wheel angle. This almost doubles the field of vision in a bend.
The dynamic cornering light function has evolved into the adaptive frontlighting system (AFS). This system relies not only on the steering wheel angle, but also on the vehicle speed, as input data to illuminate the road. Based on this internal information, different types of light distribution (including urban lighting, ex-urban lighting, adverse weather lighting, and motorway lighting) are created via a cylinder in the VarioX module.
The next step in development is the creation of the “adaptive cut-off line” (aCOL). This function also draws on data from the vehicle’s surroundings to create the appropriate light distribution. The camera detects the surrounding traffic and senses the vehicles ahead, and then, within milliseconds, the stepper motor turns the VarioX cylinder to the required position, i.e. the light cone ends right before it reaches the oncoming traffic or the vehicle ahead.
The non-glare full beam function allows drivers to drive with the full beam on at all times. If the camera detects another vehicle in the vicinity, the distribution of light from the full beam is adjusted to mask off that particular area.
Although LEDs today are mainly used to illuminate large areas, in the future they will also serve exactly the opposite function. Targeted spotlights will allow for the specific illumination of certain types of objects, such as children playing at the roadside. This will let drivers spot potential risks much earlier and react more quickly.
