Audi works within the project “ILAS” closely with our partners Bosch, Osram and the Light Technology Institute (LTI) at the Karlsruhe Institute of Technology (KIT) together. Goal are even more compact and more powerful headlights.

The accepted a three-year, funded by the Federal Ministry of Education and Research project “intelligent laser light for compact and high-resolution adaptive headlights”, short ILAS, with partners from industry and science has the Headlights of the future in mind. These include the matrix-laser technology that is based on the laser spot of the main beam, the first time brought the Audi 2014 Audi R8 in LMX series. Powerful lasers enable it at that for the first time to integrate the projector technology in a compact but powerful headlights.

Finer dynamic resolution

The new technology uses only a very fast moving micromirrors, which deflects the laser beam. At low vehicle speed, the technique contributes to wide illumination of the road, at a greater speed, the opening angle is smaller and the intensity as well as the range of the light is significantly increased. Another new feature is the lightning-fast switching on and off of the laser diode as a function of the mirror position. Unlike today’s Matrix-LED headlights, the matrix laser technology to ensure an even finer resolution and dynamic with an even higher degree of efficiency.

Quick moveable micromirror

With the new technology radiate blue laser diodes from Osram with a wavelength of 450 nanometers her light on a three millimeter large, rapidly moving mirror. This directs the blue laser light from a converter, which converts it into white light and projected onto the road. The mirror used for the company Bosch is a micro-opto-electro-mechanical system and is based on silicon technology. He is particularly robust, according to Audi, and is characterized by a long service life. Also acceleration sensors or control devices for the electronic stabilization control using such modules.
