Audi develops speed-based automotive lighting control

Keywords:Audi  Bosch  Osram  MEMS  lighting control 

Based on its laser spot high-beam headlight, Audi is moving forward by developing a system that automatically adjusts the illumination depending on the speed of the vehicle. According to the car maker, the technology makes use of only a single MEMS mirror to deflect the laser beam.

The laser spot technology for the high beam went into series production for the first time in 2014, in the Audi R8 LMX sports car. Progress in the field of laser light generation now made it possible to integrate the projector technology in a compact yet powerful headlight assembly. The latest iteration uses a single but fast-moving micro mirror that deflects the laser beam. At low speeds, the light is distributed widely across a large area. At higher speed, the aperture angle gets smaller; the intensity as well as the luminous range of the beam is increased. This is of benefit in particular during high-speed rides on motorways.

Laser spot technology

Audi is working on a system that automatically adjusts the illumination by the speed of the vehicle, a technology that uses only a single MEMS mirror to deflect the laser beam.

The technology also allows controlling the distribution of the light. Thus, the beam can illuminate specific sections of the illuminated area, resulting in a highly dynamic and variable overall illumination and, likewise, shading.
