Active light
The term active light refers to adaptive headlights with variable light distribution that adapt to traffic and environmental conditions.
In 2000, over 40,000 people were killed in road accidents and around 1.7 million injured in the EU. A large proportion of these accidents were caused by a lack of information due to poor visibility. The analysis of statistical data shows that at night the risk of being killed in a traffic accident doubles.
The equipping of motor vehicles with sensor technology also covers the area of traffic lighting technology , systems with extended functionality are created. Building on the current state of adaptive headlight systems, systems for collective illumination should adapt the light distribution to the current traffic situation so that the road is illuminated as efficiently as possible. This should improve the driver's visibility and at the same time minimize the glare of other road users.
The desire for situation-dependent adaptation of the light distribution leads to complex concepts. The cornerstones of the developments are the sensors for recording the traffic area, the manipulation of optical components and the development of new headlight concepts for the construction of modular light distributions. In recent years, numerous patents and technology demonstrators have emerged with which the first feasibility of active lighting systems could be demonstrated.
