The world’s first mass-produced full-LED
headlamp, developed by Magneti Marelli Automotive
Lighting for the Audi R8, was assigned the red dot
2008 Award for product design. The prize was
presented Monday night during the awards ceremony held
at the Aalto Theatre in Essen, Germany.
The red dot Design Award is one of the most important
and best-known events worldwide in the design sector. A jury
of experts evaluated and tested various products competing
for the award according to the following criteria:
innovation, functionality, durability, economic
compatibility, ergonomic aspects and quality. A total of
3,200 products from 51 different countries took part in this
year’s edition.
By developing the full-LED headlamp for the R8, Audi and
Magneti Marelli Automotive Lighting together have marked a
turning point in automotive design and lighting technology.
Besides the collaboration with Audi concerning design,
Magneti Marelli Automotive Lighting provided the
technological solution for the full-LED headlamp.
In this headlamp, all lighting functions – low beam, high
beam, turn signal, Day Running Light and parking light –
were developed with LED (Light-Emitting Diode) technology.
This product features more than 20 innovative concepts. The
basic light distribution is produced by two free-form
reflectors in the shape of a shell, supplied by white LED
arrays. The greatest advantage offered by white LEDs lies in
the colour of their light, which is also known as the colour
temperature. Reaching approximately 6,000° Kelvin, the
intensity of their light is just about the same as the
quality of daylight, thus ensuring excellent visibility for
improved active safety.
On top of an average useful life that is longer than that of
the vehicle itself, LED technology reduces fuel consumption
and emissions. The use of LED-equipped Day Running Lights
also makes an important contribution to a proper energy
balance, since 75% of the total driving distance in the
world is covered during the daytime. In specific terms, DRLs
with LED technology offer an energy consumption of 14 W
(with 0.36 g of CO2/km) per vehicle. When regular low beams
are used instead, energy consumption is approximately 300 W
(with 7.86g of CO2/km). This means a consumption that is 20
times greater compared to the LED daytime running lights.
From a design standpoint, the front headlamps represent the
“eyes” of a car, and they make a significant contribution to
characterising the manufacturer’s family feeling. In the
full-LED headlamp of the Audi R8, the “wing” design of the
Day running light (DRL) covers a special role, since it
delicately emphasises the curved bottom contour of the
headlamp and represents an unmistakeable element of style.
The “wing” contour of the DRL is illuminated when the car is
turned on, and serves as a daytime running light or as a
parking light with reduced lighting performances.
Twenty-four closely spaced Advanced Power Top LEDs give the
DRL a homogeneous look. The illuminated band of the daytime
running light, together with the LED turn signals, frame the
headlamp and form an absolutely unique three-dimensional
illuminated sculpture. The design of the low beam module, on
the other hand, draws inspiration from Nature, and is
reminiscent of a pinecone in the process of opening up.
These features are a clear illustration of the new design
possibilities offered by LEDs.
The use of LED technology in outside vehicle lighting is
only at the beginning. Magneti Marelli Automotive Lighting
still sees a wide range of opportunity for further
developments and future innovations in this field –
especially in combination with adaptive lighting systems and
in terms of optimising energy consumption.
