Five years ago, at the North American0MZ粤港澳工业设计网
International Auto Show in Detroit, Audi presented the Pikes Peak quattro concept study.0MZ粤港澳工业设计网

This SUV, which provided the inspiration for today’s Audi Q7, had the world’s first0MZ粤港澳工业设计网
fog lights equipped with high-performance light-emitting diodes.0MZ粤港澳工业设计网

Integrated into the0MZ粤港澳工业设计网
broad bumper as striking strips of light, the fog lights were also aesthetically pleasing and very0MZ粤港澳工业设计网
popular with the public. Soon thereafter, the 12-cylinder Audi A8 went into series production as the world’s0MZ粤港澳工业设计网
first vehicle with LED daytime running lights.0MZ粤港澳工业设计网

Today all new Audi0MZ粤港澳工业设计网
models are recognizable at a glance thanks to LED daytime running lights, not only during the day but also at night.0MZ粤港澳工业设计网

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.0MZ粤港澳工业设计网

The LED technology

A light-emitting diode, or LED, is a semiconductor device0MZ粤港澳工业设计网
just a square millimeter in size – which can convert electrical energy directly into light with a very high efficiency.0MZ粤港澳工业设计网

The first LED headlights introduced with the Pikes Peak0MZ粤港澳工业设计网
concept generated 18 lumens per watt.0MZ粤港澳工业设计网

For the sake of comparison, an ordinary household light bulb generates0MZ粤港澳工业设计网
about 20 to 25 lumens per watt. A modern passenger vehicle’s xenon headlights, on0MZ粤港澳工业设计网
the other hand, are very energy-efficient and create some 80 lumens per watt.0MZ粤港澳工业设计网

The next generation of0MZ粤港澳工业设计网
white high-performance LEDs will hit the market next year with 1000MZ粤港澳工业设计网
lumens per watt
, thus surpassing the efficiency of xenon lights for the first time.0MZ粤港澳工业设计网

Today’s xenon and LED headlights are four times more energyefficient0MZ粤港澳工业设计网
than halogen headlights.0MZ粤港澳工业设计网

By 2018, LED technology should be about eight0MZ粤港澳工业设计网
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 traditional0MZ粤港澳工业设计网
incandescent bulbs.0MZ粤港澳工业设计网

“Light-emitting diodes are similar to0MZ粤港澳工业设计网
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 that0MZ粤港澳工业设计网
entirely new applications will become possible.”
0MZ粤港澳工业设计网

Audi Q5 LED RenderingDigital light, as Berlitz calls this new light technology, can be made more or less bright0MZ粤港澳工业设计网
electronically and precisely adapted to a driver’s needs. Audi developers are0MZ粤港澳工业设计网
convinced that future generations of headlights will react to weather conditions, a0MZ粤港澳工业设计网
vehicle’s speed, the distance between vehicles, and potentially dangerous objects.0MZ粤港澳工业设计网

Developers tightly bundle several light-emitting diodes to create modules known as LED0MZ粤港澳工业设计网
arrays
.0MZ粤港澳工业设计网

These arrays are extremely flat, very compact and require much less space0MZ粤港澳工业设计网
than conventional light sources such as halogen bulbs or xenon burners.0MZ粤港澳工业设计网

Because of0MZ粤港澳工业设计网
this, and thanks to reflectors as well as sophisticated electronic controls, it is possible0MZ粤港澳工业设计网
to realize very complex lighting functions in the tightest of spaces. Cornering light, for0MZ粤港澳工业设计网
example, has traditionally been executed via complex mechanical means in0MZ粤港澳工业设计网
headlights.0MZ粤港澳工业设计网

Energy Efficiency

Audi TTS RoadsterLEDs can also reduce a vehicle’s fuel0MZ粤港澳工业设计网
consumption. Vehicles’ conventional low-beam headlights, taillights, and license-plate0MZ粤港澳工业设计网
illumination consume some 200 watts – which the alternator must constantly0MZ粤港澳工业设计网
generate.0MZ粤港澳工业设计网

By comparison, a mere 15 watts is required to power the new Audi A4’s0MZ粤港澳工业设计网
LED daytime running lights, that equates to a decrease of about 0.2 liters of0MZ粤港澳工业设计网
fuel per 100 kilometers and about 4 grams fewer CO2 emissions per kilometer.0MZ粤港澳工业设计网

This advantage will be more and more evident when daytime running lights become mandatory in the European Union0MZ粤港澳工业设计网
in May 2011.0MZ粤港澳工业设计网

LED lights in design

The tiny light sources present designers with spectacular opportunities. Stefan Sielaff,0MZ粤港澳工业设计网
Audi’s Head of Design, explains: “LEDs unlock the door to unrealized design0MZ粤港澳工业设计网
possibilities for exterior design and interiors alike.”

in a distinctive visual appearance.0MZ粤港澳工业设计网

The taillights of the Audi A6 Avant are likely the0MZ粤港澳工业设计网
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 daytime0MZ粤港澳工业设计网
running lights at the front end of the Audi A4.0MZ粤港澳工业设计网

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.0MZ粤港澳工业设计网

Sielaff adds: “LED daytime running lights epitomize this fact.0MZ粤港澳工业设计网
Every light design is different, yet there’s no mistaking that every single vehicle is an0MZ粤港澳工业设计网
Audi.
0MZ粤港澳工业设计网

"Our daytime running lights cemented the visible persona of Audi models on the0MZ粤港澳工业设计网
road and hone our progressive, sporty design.”
 0MZ粤港澳工业设计网

Bear Light ConfigurationToday different configurations of LED daytime running lights now permit distinct0MZ粤港澳工业设计网
differences among the Audi models – even in the dark.0MZ粤港澳工业设计网

A strip of light can be0MZ粤港澳工业设计网
designed to underscore a vehicle’s character, just as eyeliner emphasizes an eye.0MZ粤港澳工业设计网
This fundamentally alters the body language of Audi models.0MZ粤港澳工业设计网

“The lighting configuration of yesteryear – the radiator grille along with the round lights – called to0MZ粤港澳工业设计网
mind the face of a friendly bear,”
notes André Georgi, Senior Designer of Lighting0MZ粤港澳工业设计网
Systems.0MZ粤港澳工业设计网

“The LED daytime running lights for the A Series, e.g. on the A40MZ粤港澳工业设计网
and A5, look determined, elegant, and dynamic.
0MZ粤港澳工业设计网

"The lights on the Audi Q5 and Audi0MZ粤港澳工业设计网
Q7 appear especially broad and powerful.
0MZ粤港澳工业设计网

"And the LED daytime running lights on the0MZ粤港澳工业设计网
R8 symbolize the horns of a bull charging full speed ahead, bursting with vigor and pride.”
0MZ粤港澳工业设计网

Bull Light ConfigurationThe Audi R8 is the spearhead of Audi’s light0MZ粤港澳工业设计网
strategy and is optionally available with the world’s first all-LED headlights.0MZ粤港澳工业设计网

In addition0MZ粤港澳工业设计网
to the daytime running lights, the turn signals as well as low-beam and high-beam0MZ粤港澳工业设计网
headlights are all executed by means of light-emitting diodes.0MZ粤港澳工业设计网

Huhn explains: “A lot of people0MZ粤港澳工业设计网
initially viewed this development as a mere marketing gimmick. Yet everyone who has0MZ粤港澳工业设计网
seen these lights in action is not only astonished by the excellent output, but also0MZ粤港澳工业设计网
thrilled with the homogenous distribution of light and the agreeable, daylight-esque0MZ粤港澳工业设计网
color of the light."

Audi’s light strategy also benefits from something quite different, namely a0MZ粤港澳工业设计网
psychological phenomenon: “Bright light created by small, compact light sources is0MZ粤港澳工业设计网
unpleasant for the human eye. The combination of headlights and LED daytime0MZ粤港澳工业设计网
running lights enlarges the light source, thus eliminating a nuisance,”
explains Georgi.0MZ粤港澳工业设计网

Ideas and visions

Huhn Georgi Berlitz From left to right: Dr. Wolfgang Huhn, Head of the Light and Visibility 0MZ粤港澳工业设计网
Department, André Georgi, Senior Designer Lichtsysteme and 0MZ粤港澳工业设计网
Stephan Berlitz
, Head of Lighting Technology and Electronics0MZ粤港澳工业设计网

At Audi the0MZ粤港澳工业设计网
design process is initiated by developing and defining a vehicle’s character. The light0MZ粤港澳工业设计网
designers and engineers from Technical Development play a hands-on role in this0MZ粤港澳工业设计网
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.0MZ粤港澳工业设计网

Conversely, a lot of the technically relevant headlight components are designed by0MZ粤港澳工业设计网
Technical Development. This close rapport ensures that the departments confer with0MZ粤港澳工业设计网
one another every day.0MZ粤港澳工业设计网

As a vehicle’s exterior takes shape, the proportions of the headlights and the taillights0MZ粤港澳工业设计网
are defined. Georgi says: “It’s a truly intensive process for us to develop new0MZ粤港澳工业设计网
headlights; every idea and every vision from Technical Development and Design0MZ粤港澳工业设计网
come together.”
0MZ粤港澳工业设计网

Audi’s light designers turn to industrial design and architecture when they require0MZ粤港澳工业设计网
inspiration for new ideas.0MZ粤港澳工业设计网

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.0MZ粤港澳工业设计网

Experts forecast that LEDs, energy-efficient and maintenance-free0MZ粤港澳工业设计网
sources of light, will also become the first choice for indoor lighting.0MZ粤港澳工业设计网

Audi LED Lights Design SketchAnother source of inspiration for light designers is nature.0MZ粤港澳工业设计网

“Nature often shows us the way, allowing us to learn just how simply and effectively0MZ粤港澳工业设计网
processes can be executed,"
explains the light designer Georgi.0MZ粤港澳工业设计网

The most recent0MZ粤港澳工业设计网
example of this is the taillights we developed for the Audi A1 Sportback Concept, which was inspired by the0MZ粤港澳工业设计网
lattice structure of a dragonfly’s wing.0MZ粤港澳工业设计网

The design of the taillights impressively0MZ粤港澳工业设计网
demonstrates the relative simplicity required to construct a very large, stable and light0MZ粤港澳工业设计网
surface.0MZ粤港澳工业设计网

Georgi says: “With our bionic design, we transferred this constructional0MZ粤港澳工业设计网
conception to the Audi A1 concept’s taillights, which needed to be lightweight0MZ粤港澳工业设计网
because they are integrated in the tailgate.”

The headlights of the Audi A1 Sportback Concept are an additional illustration of nature permeating Audi design.0MZ粤港澳工业设计网
Reminiscent of an open pine cone, reflector shells arranged successively in0MZ粤港澳工业设计网
concentric circles harness the light of each individual diode to create lighting which is0MZ粤港澳工业设计网
powerful and consistent.0MZ粤港澳工业设计网

The headlights in the middle, on the other hand, are shaped0MZ粤港澳工业设计网

The future

Berlitz Stephan Berlitz, Audi Head of Lighting 0MZ粤港澳工业设计网
Technology0MZ粤港澳工业设计网
and Electronics0MZ粤港澳工业设计网

Audi developers think that the future generations of headlights will provide "the right light for every driving situation".0MZ粤港澳工业设计网

Huhn explains: “We’re striving to0MZ粤港澳工业设计网
create intelligent headlights and taillights which think and anticipate in the interest of0MZ粤港澳工业设计网
enhancing a driver’s safety and comfort.”
0MZ粤港澳工业设计网

For example, there are already high-beam0MZ粤港澳工业设计网
headlights in pre-series development which will allow drivers to navigate roads at0MZ粤港澳工业设计网
night without temporarily blinding oncoming drivers.0MZ粤港澳工业设计网

This is made possible by a0MZ粤港澳工业设计网
variable distribution of light: An electronic system continuously calculates the distance0MZ粤港澳工业设计网
to any approaching vehicles to ensure that the road ahead is ideally illuminated at all0MZ粤港澳工业设计网
times – without irritating oncoming drivers.0MZ粤港澳工业设计网

Interior lighting

LEDs also present new opportunities for interior lighting. Similar to interior0MZ粤港澳工业设计网
architecture
, lighting scenarios are imaginable which would make it safer to operate0MZ粤港澳工业设计网
the vehicle at night, render the interior considerably roomier, or impart a certain0MZ粤港澳工业设计网
atmosphere.0MZ粤港澳工业设计网

The optional interior lighting package with ambient lighting in the Audi A8 is an example. It gives the0MZ粤港澳工业设计网
possibilities for customizing the interior lights: the driver can dim the light and0MZ粤港澳工业设计网
configure various lighting profiles via the MMI.0MZ粤港澳工业设计网

Andre Georgi André Georgi, Senior Designer of Lighting System at Audi0MZ粤港澳工业设计网

These profiles respond as appropriate0MZ粤港澳工业设计网
to certain driving situations – when a vehicle’s interior is illuminated by lighting within0MZ粤港澳工业设计网
cities, for example, or becomes dark on unlit rural routes.0MZ粤港澳工业设计网

When it comes to the lighting in vehicle interiors, developers are confronted with few0MZ粤港澳工业设计网
limits. Safety and comfort are top priorities.0MZ粤港澳工业设计网

Berlitz explains: “Think of a mountain hut0MZ粤港澳工业设计网
at night. As you’re passing through an alpine meadow, you spot the warm light0MZ粤港澳工业设计网
glowing through the hut’s windows. The light triggers that same cozy sensation you0MZ粤港澳工业设计网
feel when you arrive home.”
0MZ粤港澳工业设计网

“Just imagine: You press a single button on your remote control0MZ粤港澳工业设计网
and the entire vehicle springs to life. The ‘headlight eyes’ awaken and an inviting light0MZ粤港澳工业设计网
fills the vehicle’s interior as if to say: Welcome home!”
