Audi is going to extend its lighting offer in the future years with the introduction of its new Matrix laser technology. After it inovated with Matrix LED, already offered on Audi TT, Audi A8, Audi A7 and new generation Audi Q7.
 
Matrix Laser technology is based on the LaserSpot for highbeam 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.
 
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.
 
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.
