|In lighting technology, Audi is driving progress at high tempo. Today, its xenon plus-and LED headlights already provide the best illumination of the road and give the cars with the four rings an unmistakable look.|
The future of Auto Lighting is here
In the future, vehicle lighting will react even more precisely to environmental conditions, and it will feature full electronic control. The first step in this direction will be taken this year in the form of innovative Matrix LED headlights.
Let’s look at the common LED daytime running lights and tailights which debut in an Audi A8 in 2004 of today. The LED (Light-emitting diodes) daytime lights has since been widely adopted by many auto manufacturers the world over. Audi, though, is way ahead of its competitors, for example, the Audi A1 has two LEDs per headlight that emit light into a transparent polymer tube, the light guide, which generates a uniform contour. For the A7 Sportback, the daytime running lights of the optional LED headlights also appear linear, but they originate from 18 individual LEDs with a polymer body in front of them. The LED daytime running lights consume fewer watts of power, have extremely long life and are maintenance-free.
At a glance, several Audi variants’ – A8, A7 Sportback and A3 – headlights generate a light pattern that is rather recognizable on any roads and in many cases achieve three-dimensional effects.
Xenon plus headlights are offered in all Audi variants, either as optional or standard equipment. Xenon headlights are gas discharge lamps. Two tungsten electrodes are fused in a quartz glass cylinder, known as the burner, and a concentrated light arc burns between.
Xenon headlights provide a much brighter light and better illumination than halogen headlights with incandescent bulbs, their energy consumption is about 20 percent lower and they have much longer life. With xenon plus technology, a single burner generates both the low and high beam lights, and they are switched by a moveable shutter. Of course, all xenon headlights are mercury-free.
Audi is the first marque to implement LED headlights and far ahead of the competition. First introduced in an R8 in 2008 to the A3 variant, LED light resembles daylight and is purposeful to reduce eye tiredness. LEDs are maintenance-free, last the life of the vehicle. efficient, low-beam and consume 5 percent less power than xenon plus lights.
In the motorsports circles, LEDs made debut in the R 15 TDI Le Mans sport protoype in 2010. A year later, the R18 TDI’s full-LED headlights came to light and had combined lighting power of over 200 watts to generated a light pattern with a range of over one kilometer changed the course of endurance motor racing.
Various adaptive light versions are available for the headlight systems. An electronic control module controls the swiveling xenon plus modules, or the LEDs, so that they always deliver the best possible lighting for city, highway and freeway driving. The driver can configure its mode of operation in the Audi drive select vehicle dynamics system.
Turn signal flashers with dynamized display
In updating its high-performance sports car, the R8, Audi introduced another innovation to production cars – a turn signal with dynamized display. It sends clearer signals to the environment than conventional turn signals. Today, the vehicle behind the car in traffic cannot determine whether a flashing light is a hazard light.
Matrix LED headlights
Audi’s Matrix LED headlights is the next wave of future lighting technology. it subdivides the LED high-beam light into numerous individual segments. The individual light-emitting diodes, which work in tandem with lenses or reflectors in front of them, always deliver excellent illumination, without requiring a swiveling mechanism – instead they are separately activated, deactivated or dimmed according to the situation. In addition, the Matrix LED headlights get information from the car’s camera, the navigation system and other sensors. The Matrix LED headlights will make debut later this year.
