Audi has formally announced its Matrix Laser headlights, which means the lighting system will soon be making its way onto the brand's series production vehicles. The Matrix Laser technology is based on the LaserSpot for high-beam lamps that was first introduced to production in the Audi R8 LMX last year.
It's a step up from the Matrix LED headlight tech that debuted on the Audi A8 facelift in late 2013, and the system is set to rival the BMW Laserlight system. Here, bright lasers are integrated into a projector-based system to come up with a compact, powerful and headlight with very dynamic characteristics.
At the heart of the Matrix Laser system are blue laser diodes - built by Osram - that have a wavelength of 450 nanometers, which project their light source onto a rapidly-moving mirror that is three millimeters in size.
This mirror - a micro-optical system developed by Bosch and featuring electro-mechanical control and based on silicon technology - redirects the blue laser light to a converter, which then converts it to white light and projects it onto the road.
The automaker says that activation and deactivation of the laser diodes in relation to the mirror position is lightning-fast, which allows a dynamic and highly variable broadening or narrowing of the luminous beam being projected.
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 reduced so the intensity and range of the light can be increased significantly, advantageous in highway driving. The company says that compared to the current Matrix LED headlights, Matrix Laser technology units will offer greater light throw ranges and even finer dynamic resolution.
