Lighting Technology

Whether it's the the matrix laser headlamps or organic LEDs, or adaptive light technologies the light innovations that Audi is bringing to market over the next few years combine aesthetics with amazing functionality.

Xenon Plus Headlights
 
Xenon headlights are gas discharge lamps. Two tungsten electrodes are sealed in the burner, a thick-walled quartz glass cylinder filled with xenon gas. A concentrated electric arc burns between the electrodes, and the inert gas filling exerts a pressure of as much as 100 bar (1,450.38 psi). The xenon gas itself gives off a somewhat violet light. Metallic salts in the filling of the gas cylinder reduce its color temperature to 4,200 Kelvin.

Adaptive Light
 
The adaptive light is an Audi technology for the xenon plus headlights and is available in a number of different versions. In the top models its controller manages the swiveling modules so that they always deliver the perfect light for urban, interurban and highway driving. The driver can precisely control the function of the adaptive light via the Audi drive select driving dynamics system. The all-weather light integrated into the headlight replaces the fog light.

Matrix OLED Technology
 
Audi, Matrix OLED technology (organic light emitting diode) is used in the rear lights as an option. These emit an extremely homogeneous, precise light. The light does not cast any harsh shadows and does not require any reflectors - this makes the OLEDs in 3D design efficient, lightweight and visually impressive. Each rear light contains four wafer-thin units that become smaller from the inside out.
Matrix LED headlights
 
With these headlights, the high-beam unit is made up of 25 individual segments. The small light-emitting diodes, which work in conjunction with lenses and reflectors connected in series, are activated and deactivated or dimmed individually according to the situation. This enables the system to react precisely to other cars, which it recognizes using a camera, and always illuminate the road brightly. The Audi Matrix LED headlights get the information they need from a camera, the navigation system and other sensors.
Matrix Laser Technology
 
Matrix Laser technology and its high resolution will make roadway illumination even more flexible and highly versatile - in all situations. Matrix Laser technology is based on the LaserSpot for high‑beam lamps, which Audi first introduced to production in the Audi R8 LMX. For the first time, bright lasers are making it possible to integrate projector technology in a compact and powerful headlight.
