Five years ago, at the North American2V0大灣區工業設計網
International Auto Show in Detroit, Audi presented the Pikes Peak quattro concept study.2V0大灣區工業設計網

This SUV, which provided the inspiration for today’s Audi Q7, had the world’s first2V0大灣區工業設計網
fog lights equipped with high-performance light-emitting diodes.2V0大灣區工業設計網

Integrated into the2V0大灣區工業設計網
broad bumper as striking strips of light, the fog lights were also aesthetically pleasing and very2V0大灣區工業設計網
popular with the public. Soon thereafter, the 12-cylinder Audi A8 went into series production as the world’s2V0大灣區工業設計網
first vehicle with LED daytime running lights.2V0大灣區工業設計網

Today all new Audi2V0大灣區工業設計網
models are recognizable at a glance thanks to LED daytime running lights, not only during the day but also at night.2V0大灣區工業設計網

Each Audi has its own personality in terms of lighting: the Audi A4 has a sweeping light strip which expresses elegance, while that of the Audi R8 radiates strength and dominance.2V0大灣區工業設計網

The LED technology

A light-emitting diode, or LED, is a semiconductor device2V0大灣區工業設計網
just a square millimeter in size – which can convert electrical energy directly into light with a very high efficiency.2V0大灣區工業設計網

The first LED headlights introduced with the Pikes Peak2V0大灣區工業設計網
concept generated 18 lumens per watt.2V0大灣區工業設計網

For the sake of comparison, an ordinary household light bulb generates2V0大灣區工業設計網
about 20 to 25 lumens per watt. A modern passenger vehicle’s xenon headlights, on2V0大灣區工業設計網
the other hand, are very energy-efficient and create some 80 lumens per watt.2V0大灣區工業設計網

The next generation of2V0大灣區工業設計網
white high-performance LEDs will hit the market next year with 1002V0大灣區工業設計網
lumens per watt
, thus surpassing the efficiency of xenon lights for the first time.2V0大灣區工業設計網

Today’s xenon and LED headlights are four times more energyefficient2V0大灣區工業設計網
than halogen headlights.2V0大灣區工業設計網

By 2018, LED technology should be about eight2V0大灣區工業設計網
times more efficient than halogen light. In addition, LEDs excel due to their practically indefinite service life and react up to ten times more quickly than traditional2V0大灣區工業設計網
incandescent bulbs.2V0大灣區工業設計網

“Light-emitting diodes are similar to2V0大灣區工業設計網
computer chips. Every two years there’s an increase in output of about 30 percent,”
explains Berlitz, “and we’ll soon be able to create so much light with LEDs that2V0大灣區工業設計網
entirely new applications will become possible.”
2V0大灣區工業設計網

Audi Q5 LED RenderingDigital light, as Berlitz calls this new light technology, can be made more or less bright2V0大灣區工業設計網
electronically and precisely adapted to a driver’s needs. Audi developers are2V0大灣區工業設計網
convinced that future generations of headlights will react to weather conditions, a2V0大灣區工業設計網
vehicle’s speed, the distance between vehicles, and potentially dangerous objects.2V0大灣區工業設計網

Developers tightly bundle several light-emitting diodes to create modules known as LED2V0大灣區工業設計網
arrays
.2V0大灣區工業設計網

These arrays are extremely flat, very compact and require much less space2V0大灣區工業設計網
than conventional light sources such as halogen bulbs or xenon burners.2V0大灣區工業設計網

Because of2V0大灣區工業設計網
this, and thanks to reflectors as well as sophisticated electronic controls, it is possible2V0大灣區工業設計網
to realize very complex lighting functions in the tightest of spaces. Cornering light, for2V0大灣區工業設計網
example, has traditionally been executed via complex mechanical means in2V0大灣區工業設計網
headlights.2V0大灣區工業設計網

Energy Efficiency

Audi TTS RoadsterLEDs can also reduce a vehicle’s fuel2V0大灣區工業設計網
consumption. Vehicles’ conventional low-beam headlights, taillights, and license-plate2V0大灣區工業設計網
illumination consume some 200 watts – which the alternator must constantly2V0大灣區工業設計網
generate.2V0大灣區工業設計網

By comparison, a mere 15 watts is required to power the new Audi A4’s2V0大灣區工業設計網
LED daytime running lights, that equates to a decrease of about 0.2 liters of2V0大灣區工業設計網
fuel per 100 kilometers and about 4 grams fewer CO2 emissions per kilometer.2V0大灣區工業設計網

This advantage will be more and more evident when daytime running lights become mandatory in the European Union2V0大灣區工業設計網
in May 2011.2V0大灣區工業設計網

LED lights in design

The tiny light sources present designers with spectacular opportunities. Stefan Sielaff,2V0大灣區工業設計網
Audi’s Head of Design, explains: “LEDs unlock the door to unrealized design2V0大灣區工業設計網
possibilities for exterior design and interiors alike.”

The taillights of the Audi A6 Avant are likely the2V0大灣區工業設計網
best-known example of any tail end. These light-emitting diodes in a ring-shaped array have become every bit as instantly recognizable as the sweeping LED daytime2V0大灣區工業設計網
running lights at the front end of the Audi A4.2V0大灣區工業設計網

Headlights naturally play a pivotal role in a vehicle’s light design. An appealing front end with one-of-a-kind lights makes a car as well as its personality and the brand recognizable at a glance.2V0大灣區工業設計網

Sielaff adds: “LED daytime running lights epitomize this fact.2V0大灣區工業設計網
Every light design is different, yet there’s no mistaking that every single vehicle is an2V0大灣區工業設計網
Audi.
2V0大灣區工業設計網

"Our daytime running lights cemented the visible persona of Audi models on the2V0大灣區工業設計網
road and hone our progressive, sporty design.”
 2V0大灣區工業設計網

Bear Light ConfigurationToday different configurations of LED daytime running lights now permit distinct2V0大灣區工業設計網
differences among the Audi models – even in the dark.2V0大灣區工業設計網

A strip of light can be2V0大灣區工業設計網
designed to underscore a vehicle’s character, just as eyeliner emphasizes an eye.2V0大灣區工業設計網
This fundamentally alters the body language of Audi models.2V0大灣區工業設計網

“The lighting configuration of yesteryear – the radiator grille along with the round lights – called to2V0大灣區工業設計網
mind the face of a friendly bear,”
notes André Georgi, Senior Designer of Lighting2V0大灣區工業設計網
Systems.2V0大灣區工業設計網

“The LED daytime running lights for the A Series, e.g. on the A42V0大灣區工業設計網
and A5, look determined, elegant, and dynamic.
2V0大灣區工業設計網

"The lights on the Audi Q5 and Audi2V0大灣區工業設計網
Q7 appear especially broad and powerful.
2V0大灣區工業設計網

"And the LED daytime running lights on the2V0大灣區工業設計網
R8 symbolize the horns of a bull charging full speed ahead, bursting with vigor and pride.”
2V0大灣區工業設計網

Bull Light ConfigurationThe Audi R8 is the spearhead of Audi’s light2V0大灣區工業設計網
strategy and is optionally available with the world’s first all-LED headlights.2V0大灣區工業設計網

In addition2V0大灣區工業設計網
to the daytime running lights, the turn signals as well as low-beam and high-beam2V0大灣區工業設計網
headlights are all executed by means of light-emitting diodes.2V0大灣區工業設計網

Huhn explains: “A lot of people2V0大灣區工業設計網
initially viewed this development as a mere marketing gimmick. Yet everyone who has2V0大灣區工業設計網
seen these lights in action is not only astonished by the excellent output, but also2V0大灣區工業設計網
thrilled with the homogenous distribution of light and the agreeable, daylight-esque2V0大灣區工業設計網
color of the light."

Audi’s light strategy also benefits from something quite different, namely a2V0大灣區工業設計網
psychological phenomenon: “Bright light created by small, compact light sources is2V0大灣區工業設計網
unpleasant for the human eye. The combination of headlights and LED daytime2V0大灣區工業設計網
running lights enlarges the light source, thus eliminating a nuisance,”
explains Georgi.2V0大灣區工業設計網

Ideas and visions

, Head of Lighting Technology and Electronics2V0大灣區工業設計網

At Audi the2V0大灣區工業設計網
design process is initiated by developing and defining a vehicle’s character. The light2V0大灣區工業設計網
designers and engineers from Technical Development play a hands-on role in this2V0大灣區工業設計網
process from the word go. For example, one of the engineers – fittingly nicknamed “The Bridge” by his colleagues – works right in the middle of the Design Department.2V0大灣區工業設計網

Conversely, a lot of the technically relevant headlight components are designed by2V0大灣區工業設計網
Technical Development. This close rapport ensures that the departments confer with2V0大灣區工業設計網
one another every day.2V0大灣區工業設計網

As a vehicle’s exterior takes shape, the proportions of the headlights and the taillights2V0大灣區工業設計網
are defined. Georgi says: “It’s a truly intensive process for us to develop new2V0大灣區工業設計網
headlights; every idea and every vision from Technical Development and Design2V0大灣區工業設計網
come together.”
2V0大灣區工業設計網

Audi’s light designers turn to industrial design and architecture when they require2V0大灣區工業設計網
inspiration for new ideas.2V0大灣區工業設計網

In fact, more and more architects are integrating high-tech LEDs into their plans for new buildings, thus joining a worldwide shift toward energy-efficient lighting.2V0大灣區工業設計網

Experts forecast that LEDs, energy-efficient and maintenance-free2V0大灣區工業設計網
sources of light, will also become the first choice for indoor lighting.2V0大灣區工業設計網

Audi LED Lights Design SketchAnother source of inspiration for light designers is nature.2V0大灣區工業設計網

“Nature often shows us the way, allowing us to learn just how simply and effectively2V0大灣區工業設計網
processes can be executed,"
explains the light designer Georgi.2V0大灣區工業設計網

The most recent2V0大灣區工業設計網
example of this is the taillights we developed for the Audi A1 Sportback Concept, which was inspired by the2V0大灣區工業設計網
lattice structure of a dragonfly’s wing.2V0大灣區工業設計網

The design of the taillights impressively2V0大灣區工業設計網
demonstrates the relative simplicity required to construct a very large, stable and light2V0大灣區工業設計網
surface.2V0大灣區工業設計網

Georgi says: “With our bionic design, we transferred this constructional2V0大灣區工業設計網
conception to the Audi A1 concept’s taillights, which needed to be lightweight2V0大灣區工業設計網
because they are integrated in the tailgate.”

The future

Berlitz Stephan Berlitz, Audi Head of Lighting 2V0大灣區工業設計網
Technology2V0大灣區工業設計網
and Electronics2V0大灣區工業設計網

Audi developers think that the future generations of headlights will provide "the right light for every driving situation".2V0大灣區工業設計網

Huhn explains: “We’re striving to2V0大灣區工業設計網
create intelligent headlights and taillights which think and anticipate in the interest of2V0大灣區工業設計網
enhancing a driver’s safety and comfort.”
2V0大灣區工業設計網

For example, there are already high-beam2V0大灣區工業設計網
headlights in pre-series development which will allow drivers to navigate roads at2V0大灣區工業設計網
night without temporarily blinding oncoming drivers.2V0大灣區工業設計網

This is made possible by a2V0大灣區工業設計網
variable distribution of light: An electronic system continuously calculates the distance2V0大灣區工業設計網
to any approaching vehicles to ensure that the road ahead is ideally illuminated at all2V0大灣區工業設計網
times – without irritating oncoming drivers.2V0大灣區工業設計網

Interior lighting

LEDs also present new opportunities for interior lighting. Similar to interior2V0大灣區工業設計網
architecture
, lighting scenarios are imaginable which would make it safer to operate2V0大灣區工業設計網
the vehicle at night, render the interior considerably roomier, or impart a certain2V0大灣區工業設計網
atmosphere.2V0大灣區工業設計網

The optional interior lighting package with ambient lighting in the Audi A8 is an example. It gives the2V0大灣區工業設計網
possibilities for customizing the interior lights: the driver can dim the light and2V0大灣區工業設計網
configure various lighting profiles via the MMI.2V0大灣區工業設計網

Andre Georgi André Georgi, Senior Designer of Lighting System at Audi2V0大灣區工業設計網

These profiles respond as appropriate2V0大灣區工業設計網
to certain driving situations – when a vehicle’s interior is illuminated by lighting within2V0大灣區工業設計網
cities, for example, or becomes dark on unlit rural routes.2V0大灣區工業設計網

When it comes to the lighting in vehicle interiors, developers are confronted with few2V0大灣區工業設計網
limits. Safety and comfort are top priorities.2V0大灣區工業設計網

Berlitz explains: “Think of a mountain hut2V0大灣區工業設計網
at night. As you’re passing through an alpine meadow, you spot the warm light2V0大灣區工業設計網
glowing through the hut’s windows. The light triggers that same cozy sensation you2V0大灣區工業設計網
feel when you arrive home.”
2V0大灣區工業設計網

“Just imagine: You press a single button on your remote control2V0大灣區工業設計網
and the entire vehicle springs to life. The ‘headlight eyes’ awaken and an inviting light2V0大灣區工業設計網
fills the vehicle’s interior as if to say: Welcome home!”
