Audi confidently expands its lightning technology and remains on the leading place. The latest project, called the "intelligent laser light for compact and high-resolution adaptive headlights" and has the ambition to create the headlights of the future. The used technology is called  Matrix Laser and will make the road illumination even more flexible and efficient.

Matrix Laser technology is based on the LaserSpot project, that Audi first introduced in the Audi R8 LMX. And now, for the first time bright lasers allow the whole technology to be available in compact and powerful unit, as the headlight is.

The technology itself operates with a micro-mirror, that manages to redirect the laser beam. The dynamics ensure, that when you drive at low speed, you will have a great area in front of you, that is illuminated and when you go on high speed, the angle gets smaller, which results on a higher intensity and range. Handy. As you suggested, this will be extremely helpful gadget, when used on the highway.

Another intelligent feature is the activation and deactivation of the diodes in relation to the mirror position. This makes the illumination beam responsive and dynamic. The idea behind the dynamics is to make the road highly illuminated, while other drivers and pedestrians get reduced glare. Wonderful tech, when it comes to safety and comfort, isn't it?

There is even a blue laser diodes, that produce their light on a moving mirror, which blends the blue and white lights and projects them on the road. The mirror, used for the blending is a special Bosch unit, that is based on a silicon technology. These same units are used also for the electronic stability control.

In general, Audi really defends its leading positions, when it comes to illuminating technology and the latest product proves it. Tell me what you think in the comment section.

Press release:

April 28, 2015 | INGOLSTADT, Germany -- Audi is further extending its lead in automotive lighting technology. In the sponsored project "intelligent laser light for compact and high-resolution adaptive headlights" (iLaS), the brand with the four rings is working on the headlights of the future with partners from industry and science. 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.

The new technology operates with a rapidly moving micro-mirror, which redirects the laser beam. At low vehicle speeds, the light is distributed to a larger projection area, and the road is illuminated with a very wide range. At high speeds, the aperture angle is smaller, and the intensity and range of the light are increased significantly. This is especially advantageous in highway driving. In addition, the light can be distributed precisely. This means that the brightness of different lighting zones can be varied by controlling the illumination dwell times in the specific zones.

Also new is intelligent and lightning-fast activation and deactivation of the laser diodes in relation to the mirror position. This makes the broadening or narrowing of the luminous beam dynamic and highly variable. As with today's Matrix LED headlights from Audi, the road is always brightly lit without causing glare to other participants in traffic. The crucial difference is that Matrix Laser technology offers even finer dynamic resolution and therefore a higher degree of utilization, which leads to greater safety in road traffic.

In the new technology, blue laser diodes from OSRAM radiate their light, which has a wavelength of 450 nanometers, onto a quickly moving mirror that is three millimeters in size. This mirror redirects the blue laser light to a converter, which converts it to white light and projects it onto the road. The mirror used for this, which comes from the Bosch company, is a micro-optical system that features electro-mechanical control and is based on silicon technology. It is very sturdy and exhibits very long life. Such components are also used for accelerometers and control units for electronic stability control.

For many years now, Audi has been the leader in automotive lighting technology. Some of the brand's key innovations:

2003: Audi A8 with adaptive light 2004: Audi A8 W12 with LED daytime running lights 2008: Audi R8 with all-LED headlights 2010: Audi A8 in which the headlights are networked with the navigation data 2012: Audi R8 with dynamic turn signal lights 2013: Audi A8 with Matrix LED headlights 2014: Audi R8 LMX with LaserSpot for the high-beam lamps

In the framework of the three-year "iLaS" project, Audi is working closely with its partners Bosch, Osram and the Lichttechnischen Institut (LTI; "Lighting Technology Institute") of the Karlsruhe Institute for Technology (KIT). The project is sponsored by the German Federal Ministry for Education and Research.
