Engineering teams at Nissan are trying to solve the problem of LED car headlights dazzling oncoming drivers, notably thanks to a high-tech “anti-glare notch”.

The arrival of LED technology in car headlights has not only made people happy. With higher power for lower consumption compared to halogen headlights, manufacturers have been able to reduce their size and modify their shape. If this stronger lighting allows the driver to see the road better at night, the problem is that it also tends to dazzle oncoming drivers.
Directional headlights are a partial solution. Thanks to a set of sensors, the light beam is deflected to follow the trajectory of the car. However, this is still not enough. This is why Nissan is developing its own technique to reduce the glare caused by its headlights.
An anti-glare notch
The firm creates LED headlights with an asymmetrical beam, and an “anti-glare notch” to block the light from oncoming cars. This kind of technique already existed with halogen headlights, but this is a high-tech version.
« We use computer-aided ray-tracing technology to focus light with pinpoint precision, eliminating the need for bulky reflectors and floodlightssaid Brad Chisholm, an engineer with Nissan’s lights, mirrors and wipers team. We have the ability to demarcate the area of the oncoming traffic lane, with everything around it being bright, and the interior being very dark “. Nissan indicates in particular that the use of sensors and cameras allows finer adjustment in real time, and that its headlights will undergo a battery of 300 tests before entering production.
