While the new Audi R8 will set new standards among high-performance sports cars, its lighting technology too would demonstrate
a high. As an option, the latest car development by Audi can be equipped with a
laser spot as the high-beam
headlight. The special appeal of laser lighting is that it uses high-intensity laser diodes, which generate a lot of light energy
from a very small component. Compared to LED high-beam headlights, laser high-beams
attain nearly twice the lighting range, says Audi in a report.
Audi is revealing the headlights of its new R8 as the first
of a number of technology highlights of the top sports car. The R8 uses LED
headlights which can be supplemented by a laser high beam lighting module as an
Each headlight contains one laser module that operates with
four high-intensity laser diodes. This
module bundles the four intense blue-light laser
beams. Then a phosphor converter transforms the blue light into pure white
light. An identifying characteristic of the laser headlights is their blue
light signature. Standard equipment in the new R8 includes an LED
headlight system. All lighting functions are produced with 37 LEDs per
The laser spot for the high-beam light made its debut in the summer of 2014 in the Audi R8 LMX, a
limited edition model of the previous R8 model series. Shortly before
that, it was used in the Audi R18 e-tron
quattro race car at the 24 Hours of Le Mans. The laser spot is the latest production
technology in a long line of lighting innovations. Audi introduced LED
technology to the market for the first time in 2004 – in the daytime
running lights of the Audi A8 L W12. Lighting technologies such as LED daytime
running lights, Matrix LED headlights and laser spot high-beam lights are prime examples of technology that visualise the core
values of the Audi brand: progressiveness, sportiness and
sophistication, the report added.
