Audi A8 in a new radiant light

Innovative lighting technology for the new Audi A8

They provide high-precision illumination, have individually controllable light-emitting diodes and a crystalline sheen: the innovative Matrix LED headlights for the new and improved Audi A8 provide a special driving experience at night – and set new standards in safety.

Lights on – lights off

The new Audi A8 will feature the new Audi Matrix LED technology when it makes its trade fair debut at the International Motor Show 2013 in Frankfurt. In high-beam mode too, it ensures bright, homogeneous illumination of the road. The system dims light that would shine directly onto oncoming and preceding vehicles, but continues to cast its full light on the zones between and beside them. This works because the LED high beams are split into numerous individual light-emitting diodes.

 

“The Matrix LED headlights are a perfect example of our lighting strategy. They are three-dimensional, dynamic and interactive”, explains Stephan Berlitz, Head of Development for Lighting Functions and Innovations at Audi. The 50 high-beam LEDs in both headlights are arranged in a matrix and adapt fully electronically to the surroundings in milliseconds. They are activated and deactivated or dimmed individually by a control unit.

 

The new Matrix LED technology is activated from a speed of 30 km/h outside built-up areas and from 60 km/h in towns and cities. This happens only if the light switch in the new Audi A8 is set to “automatic” and the high-beam headlights are on. A camera in the vehicle ensures that other vehicles are detected.

On the safe side

But the Matrix LED headlights can do even more: with new functions, they provide greater safety. These include the marker lights that work together with the optional night vision assistant. As soon as a pedestrian is detected in a critical range in front of the vehicle, individual LEDs flash briefly three times in succession to alert that person, who is then clearly visible to the driver.

 

In addition, the Audi Matrix LED headlights also function as a cornering light. Using predictive route data supplied by the MMI navigation plus, the focus of the beam is shifted towards the bend even before the driver turns the steering wheel. 

 

The automotive lighting technology in the new Audi A8 is rounded off by another premiere. For the first time, an LED headlight features a turn signal with a dynamic display. This technology is already integrated into the rear lights of the Audi R8. The illuminated LEDs on the new Audi A8 now flash in blocks inside the headlight too, in the direction in which the driver intends to turn. The turn signal is therefore more intuitive and is recognised more quickly.
