Five years ago, at the North AmericanDIu大湾区工业设计网
International Auto Show in Detroit, Audi presented the Pikes Peak quattro concept study.DIu大湾区工业设计网

This SUV, which provided the inspiration for today’s Audi Q7, had the world’s firstDIu大湾区工业设计网
fog lights equipped with high-performance light-emitting diodes.DIu大湾区工业设计网

Integrated into theDIu大湾区工业设计网
broad bumper as striking strips of light, the fog lights were also aesthetically pleasing and veryDIu大湾区工业设计网
popular with the public. Soon thereafter, the 12-cylinder Audi A8 went into series production as the world’sDIu大湾区工业设计网
first vehicle with LED daytime running lights.DIu大湾区工业设计网

Today all new AudiDIu大湾区工业设计网
models are recognizable at a glance thanks to LED daytime running lights, not only during the day but also at night.DIu大湾区工业设计网

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.DIu大湾区工业设计网

The LED technology

A light-emitting diode, or LED, is a semiconductor deviceDIu大湾区工业设计网
just a square millimeter in size – which can convert electrical energy directly into light with a very high efficiency.DIu大湾区工业设计网

The first LED headlights introduced with the Pikes PeakDIu大湾区工业设计网
concept generated 18 lumens per watt.DIu大湾区工业设计网

For the sake of comparison, an ordinary household light bulb generatesDIu大湾区工业设计网
about 20 to 25 lumens per watt. A modern passenger vehicle’s xenon headlights, onDIu大湾区工业设计网
the other hand, are very energy-efficient and create some 80 lumens per watt.DIu大湾区工业设计网

The next generation ofDIu大湾区工业设计网
white high-performance LEDs will hit the market next year with 100DIu大湾区工业设计网
lumens per watt
, thus surpassing the efficiency of xenon lights for the first time.DIu大湾区工业设计网

Today’s xenon and LED headlights are four times more energyefficientDIu大湾区工业设计网
than halogen headlights.DIu大湾区工业设计网

By 2018, LED technology should be about eightDIu大湾区工业设计网
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 traditionalDIu大湾区工业设计网
incandescent bulbs.DIu大湾区工业设计网

“Light-emitting diodes are similar toDIu大湾区工业设计网
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 thatDIu大湾区工业设计网
entirely new applications will become possible.”
DIu大湾区工业设计网

Audi Q5 LED RenderingDigital light, as Berlitz calls this new light technology, can be made more or less brightDIu大湾区工业设计网
electronically and precisely adapted to a driver’s needs. Audi developers areDIu大湾区工业设计网
convinced that future generations of headlights will react to weather conditions, aDIu大湾区工业设计网
vehicle’s speed, the distance between vehicles, and potentially dangerous objects.DIu大湾区工业设计网

Developers tightly bundle several light-emitting diodes to create modules known as LEDDIu大湾区工业设计网
arrays
.DIu大湾区工业设计网

These arrays are extremely flat, very compact and require much less spaceDIu大湾区工业设计网
than conventional light sources such as halogen bulbs or xenon burners.DIu大湾区工业设计网

Because ofDIu大湾区工业设计网
this, and thanks to reflectors as well as sophisticated electronic controls, it is possibleDIu大湾区工业设计网
to realize very complex lighting functions in the tightest of spaces. Cornering light, forDIu大湾区工业设计网
example, has traditionally been executed via complex mechanical means inDIu大湾区工业设计网
headlights.DIu大湾区工业设计网

Energy Efficiency

Audi TTS RoadsterLEDs can also reduce a vehicle’s fuelDIu大湾区工业设计网
consumption. Vehicles’ conventional low-beam headlights, taillights, and license-plateDIu大湾区工业设计网
illumination consume some 200 watts – which the alternator must constantlyDIu大湾区工业设计网
generate.DIu大湾区工业设计网

By comparison, a mere 15 watts is required to power the new Audi A4’sDIu大湾区工业设计网
LED daytime running lights, that equates to a decrease of about 0.2 liters ofDIu大湾区工业设计网
fuel per 100 kilometers and about 4 grams fewer CO2 emissions per kilometer.DIu大湾区工业设计网

This advantage will be more and more evident when daytime running lights become mandatory in the European UnionDIu大湾区工业设计网
in May 2011.DIu大湾区工业设计网

LED lights in design

The tiny light sources present designers with spectacular opportunities. Stefan Sielaff,DIu大湾区工业设计网
Audi’s Head of Design, explains: “LEDs unlock the door to unrealized designDIu大湾区工业设计网
possibilities for exterior design and interiors alike.”

The taillights of the Audi A6 Avant are likely theDIu大湾区工业设计网
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 daytimeDIu大湾区工业设计网
running lights at the front end of the Audi A4.DIu大湾区工业设计网

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.DIu大湾区工业设计网

Sielaff adds: “LED daytime running lights epitomize this fact.DIu大湾区工业设计网
Every light design is different, yet there’s no mistaking that every single vehicle is anDIu大湾区工业设计网
Audi.
DIu大湾区工业设计网

"Our daytime running lights cemented the visible persona of Audi models on theDIu大湾区工业设计网
road and hone our progressive, sporty design.”
 DIu大湾区工业设计网

Bear Light ConfigurationToday different configurations of LED daytime running lights now permit distinctDIu大湾区工业设计网
differences among the Audi models – even in the dark.DIu大湾区工业设计网

A strip of light can beDIu大湾区工业设计网
designed to underscore a vehicle’s character, just as eyeliner emphasizes an eye.DIu大湾区工业设计网
This fundamentally alters the body language of Audi models.DIu大湾区工业设计网

“The lighting configuration of yesteryear – the radiator grille along with the round lights – called toDIu大湾区工业设计网
mind the face of a friendly bear,”
notes André Georgi, Senior Designer of LightingDIu大湾区工业设计网
Systems.DIu大湾区工业设计网

“The LED daytime running lights for the A Series, e.g. on the A4DIu大湾区工业设计网
and A5, look determined, elegant, and dynamic.
DIu大湾区工业设计网

"The lights on the Audi Q5 and AudiDIu大湾区工业设计网
Q7 appear especially broad and powerful.
DIu大湾区工业设计网

"And the LED daytime running lights on theDIu大湾区工业设计网
R8 symbolize the horns of a bull charging full speed ahead, bursting with vigor and pride.”
DIu大湾区工业设计网

Bull Light ConfigurationThe Audi R8 is the spearhead of Audi’s lightDIu大湾区工业设计网
strategy and is optionally available with the world’s first all-LED headlights.DIu大湾区工业设计网

In additionDIu大湾区工业设计网
to the daytime running lights, the turn signals as well as low-beam and high-beamDIu大湾区工业设计网
headlights are all executed by means of light-emitting diodes.DIu大湾区工业设计网

Huhn explains: “A lot of peopleDIu大湾区工业设计网
initially viewed this development as a mere marketing gimmick. Yet everyone who hasDIu大湾区工业设计网
seen these lights in action is not only astonished by the excellent output, but alsoDIu大湾区工业设计网
thrilled with the homogenous distribution of light and the agreeable, daylight-esqueDIu大湾区工业设计网
color of the light."

Audi’s light strategy also benefits from something quite different, namely aDIu大湾区工业设计网
psychological phenomenon: “Bright light created by small, compact light sources isDIu大湾区工业设计网
unpleasant for the human eye. The combination of headlights and LED daytimeDIu大湾区工业设计网
running lights enlarges the light source, thus eliminating a nuisance,”
explains Georgi.DIu大湾区工业设计网

Ideas and visions

Department, André Georgi, Senior Designer Lichtsysteme and DIu大湾区工业设计网
Stephan Berlitz
, Head of Lighting Technology and ElectronicsDIu大湾区工业设计网

At Audi theDIu大湾区工业设计网
design process is initiated by developing and defining a vehicle’s character. The lightDIu大湾区工业设计网
designers and engineers from Technical Development play a hands-on role in thisDIu大湾区工业设计网
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.DIu大湾区工业设计网

Conversely, a lot of the technically relevant headlight components are designed byDIu大湾区工业设计网
Technical Development. This close rapport ensures that the departments confer withDIu大湾区工业设计网
one another every day.DIu大湾区工业设计网

As a vehicle’s exterior takes shape, the proportions of the headlights and the taillightsDIu大湾区工业设计网
are defined. Georgi says: “It’s a truly intensive process for us to develop newDIu大湾区工业设计网
headlights; every idea and every vision from Technical Development and DesignDIu大湾区工业设计网
come together.”
DIu大湾区工业设计网

Audi’s light designers turn to industrial design and architecture when they requireDIu大湾区工业设计网
inspiration for new ideas.DIu大湾区工业设计网

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.DIu大湾区工业设计网

Experts forecast that LEDs, energy-efficient and maintenance-freeDIu大湾区工业设计网
sources of light, will also become the first choice for indoor lighting.DIu大湾区工业设计网

Audi LED Lights Design SketchAnother source of inspiration for light designers is nature.DIu大湾区工业设计网

“Nature often shows us the way, allowing us to learn just how simply and effectivelyDIu大湾区工业设计网
processes can be executed,"
explains the light designer Georgi.DIu大湾区工业设计网

The most recentDIu大湾区工业设计网
example of this is the taillights we developed for the Audi A1 Sportback Concept, which was inspired by theDIu大湾区工业设计网
lattice structure of a dragonfly’s wing.DIu大湾区工业设计网

The design of the taillights impressivelyDIu大湾区工业设计网
demonstrates the relative simplicity required to construct a very large, stable and lightDIu大湾区工业设计网
surface.DIu大湾区工业设计网

Georgi says: “With our bionic design, we transferred this constructionalDIu大湾区工业设计网
conception to the Audi A1 concept’s taillights, which needed to be lightweightDIu大湾区工业设计网
because they are integrated in the tailgate.”

Reminiscent of an open pine cone, reflector shells arranged successively inDIu大湾区工业设计网

powerful and consistent.DIu大湾区工业设计网

The future

Berlitz Stephan Berlitz, Audi Head of Lighting DIu大湾区工业设计网
TechnologyDIu大湾区工业设计网
and ElectronicsDIu大湾区工业设计网

Audi developers think that the future generations of headlights will provide "the right light for every driving situation".DIu大湾区工业设计网

Huhn explains: “We’re striving toDIu大湾区工业设计网
create intelligent headlights and taillights which think and anticipate in the interest ofDIu大湾区工业设计网
enhancing a driver’s safety and comfort.”
DIu大湾区工业设计网

For example, there are already high-beamDIu大湾区工业设计网
headlights in pre-series development which will allow drivers to navigate roads atDIu大湾区工业设计网
night without temporarily blinding oncoming drivers.DIu大湾区工业设计网

This is made possible by aDIu大湾区工业设计网
variable distribution of light: An electronic system continuously calculates the distanceDIu大湾区工业设计网
to any approaching vehicles to ensure that the road ahead is ideally illuminated at allDIu大湾区工业设计网
times – without irritating oncoming drivers.DIu大湾区工业设计网

Interior lighting

LEDs also present new opportunities for interior lighting. Similar to interiorDIu大湾区工业设计网
architecture
, lighting scenarios are imaginable which would make it safer to operateDIu大湾区工业设计网
the vehicle at night, render the interior considerably roomier, or impart a certainDIu大湾区工业设计网
atmosphere.DIu大湾区工业设计网

The optional interior lighting package with ambient lighting in the Audi A8 is an example. It gives theDIu大湾区工业设计网
possibilities for customizing the interior lights: the driver can dim the light andDIu大湾区工业设计网
configure various lighting profiles via the MMI.DIu大湾区工业设计网

Andre Georgi André Georgi, Senior Designer of Lighting System at AudiDIu大湾区工业设计网

These profiles respond as appropriateDIu大湾区工业设计网
to certain driving situations – when a vehicle’s interior is illuminated by lighting withinDIu大湾区工业设计网
cities, for example, or becomes dark on unlit rural routes.DIu大湾区工业设计网

When it comes to the lighting in vehicle interiors, developers are confronted with fewDIu大湾区工业设计网
limits. Safety and comfort are top priorities.DIu大湾区工业设计网

Berlitz explains: “Think of a mountain hutDIu大湾区工业设计网
at night. As you’re passing through an alpine meadow, you spot the warm lightDIu大湾区工业设计网
glowing through the hut’s windows. The light triggers that same cozy sensation youDIu大湾区工业设计网
feel when you arrive home.”
DIu大湾区工业设计网

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