Specifications

The Audi R8 was setting standards as early as
2008 as the first sports car with all-LED
headlights. Now this special lighting is also
available for the Audi A6 on request. All-LED
headlights (optional) not only require less
energy than standard lighting systems, but also
provide a brighter light which is perceived to be
much more pleasant. The dipped beam consists
of a distinctive line of three individual light
modules. This makes the Audi A6 unmistakable,
even at night. The main beam, daytime running
lights and indicators are also made in LED
technology. The use of the same material for all
functions makes completely new lighting effects
possible. The Audi A6, therefore, has the right
light for every situation: It has a motorway light
which, at speeds above 110 km/h, automatically
almost doubles the range of the light cone (from
approx. 70 m at dipped beam to 120 m with
motorway light). In addition,
the A6 Sedan has a combined daytime running
light/indicator light unit and an all-weather
light which makes conventional fog lights
superfluous. The individual LED modules are
skilfully controlled to redistribute the light,
reducing glare from rain or fog.

Subject: Light
Conventional light bulbs reach temperatures of up to 300 °C. Due to their sophisticated
technology, LED lights are somewhat more sensitive and should not get hotter
than 150 °C. Because of the engine, the temperature of the area around the headlights
is already around 120 °C. In theory, then, LED headlights would need an additional
cooling system to be able to work. However, the Audi engineers did not want to
spoil the good low-energy credentials of the LED headlights, so they quickly developed
something completely new: a fan which directs heat away from the LED chips. The special
feature of this fan is its additional benefit. The high operating temperature of
standard bulbs means that they can defrost the headlights, which LEDs cannot. The
newly developed fan directs warm air from the LED chips directly to the headlight
clear glass cover and thus defrosts it and prevents it from misting up.
