With the new Opel Astra, which celebrates its premiere at the IAA in September, debuts light technology in the compact class: Matrix LED headlights shine brighter, more economically and automatically adapted to the traffic situation.
The lighting system consists of eight lighting elements per headlight and can thus be precisely controlled. It works with the front camera to adjust the light beam to the optimal length and to distribute the light cone.
As soon as the vehicle leaves the city, the high beam is permanently switched on as standard - a safety plus for the driver. If the camera detects oncoming or driving vehicles ahead, individual LEDs are deactivated and the affected vehicles are hidden. The rest of the street and the surrounding area remain illuminated. There is also a special motorway light mode.
Thanks to LED technology, the headlights are more efficient and long-lasting than halogen or xenon lamps, and they also shine brighter. In addition, mechanical movement in the headlamp is no longer necessary, the individual LED elements switch on or off depending on the situation, which should also contribute to durability. Thanks to the small LEDs, the designers will have the advantage of a more delicate front design in the future.
So far, the technology has only been available in higher-priced models from premium manufacturers, such as the Audi A8 or the Mercedes C-Class.
