Last October, German carmaker Audi introduced LED headlights with a digital matrix that can project images.

The product is made up of 1.3 million micro-mirrors, each of which emits tiny and uniquely adaptive light particles that project images when the car is stopped or moving. The product also provides a 50-metre "light blanket" that illuminates up to 50 metres in front of the lane when the headlights are switched on. This is designed to prevent the driver or pedestrian of the opposite vehicle from instantly losing their sight.

In addition, the curved light can also help drivers detect other objects or pedestrians on the road.

Nine, laser headlights

Last October, German luxury carmaker BMW introduced its innovative Laserlight headlamp and related technology to the market.

Despite its name, LaserLight passes three monochrome blue laser beams through a series of mirrors in the main housing. Finally, LaserLight passes through a filter filled with yellow phosphorus. The blue laser reacts with the yellow phosphorus to produce a bright, cone-shaped white beam that points directly to the road. Using this technology, the product produces lights that are ten times brighter than traditional LED headlights. Since urban traffic may distract drivers, the product will only be used at speeds above 60 km/h on urban roads to improve safety.

More importantly, an integrated infra-red camera system used in combination with LaserLight detects a vehicle moving in the opposite direction and sends a signal to a control unit, which automatically dimms headlights without the need for manual input from the driver. If the infrared camera system detects an obstacle in the road, LaserLight focuses the beam directly on the obstacle at a distance of up to 300 feet (92 meters).

At the same time, LaserLight can communicate with the car's GPS navigation system to anticipate road turns ahead of time, allowing it to follow and turn.
