LED matrix headlight
At this year’s Geneva International Motor Show, Opel presented the LED matrix headlights. It was developed in cooperation with ZKW.
Compared to the previous matrix light, which has been available in the Opel Astra for two years, the Intellilux offers additional high-resolution, glare-free high beam lights. Ten high-power LEDs that can be switched on and off selectively are the basis of the light system. This permits various low-beam and high-beam combinations. The LED headlight connectable to the CAN in-vehicle networks is controlled via a connected front camera that lets the system automatically adjust the high beam and prevent dangerous glare.
“The fully automated Intellilux system of the new Opel Insignia provides optimum support to the driver and allows a relaxing drive with maximum safety. This will make driving even safer and more comfortable, especially at night,” said Oliver Schubert, CEO of the ZKW Group that developed the LED matrix headlight for Opel.
Over a four-year period of development work, ZKW has optimized the headlight even more. The ten high-power LED light sources now form the low-beam light via a three-chamber reflector and a projection lens. The matrix high beam for turning off individual high-beam segments – in order to prevent glare to oncoming traffic or vehicles in front – is generated via two additional projection lenses with 16 LEDs that are controlled separately. The high-beam spot enables an illumination of up to 400 m due to two additional high-power LEDs. Adaptive forward lighting has also been improved: A reflector integrated on the inside of the headlight ensures an even better illumination than before when the car turns. A typical styling element of the Insignia is a double-wing daytime running light and indicator light that was implemented using four light guides.
Each LED is controlled in line with vehicle parameters – such as front camera object data as well as speed and steering angle. The result is a headlight that reacts automatically and independently, switches to high-beam mode outside the city limits, and continuously adjusts the length and distribution of the light beam to traffic situations. This means that the system pro-actively supports the driver at night – regardless of whether you are driving on a highway, country road, in a city, or through curves. “The state-of-the-art system literally turns night into day for drivers and passengers of the new Opel Insignia without blinding other traffic,” said Ingolf Schneider, Lighting Technology Manager at Opel.
