The potential for active night-vision systems to increase the visual range without dazzling oncoming traffic is explored. The system is based on an infrared headlamp, a camera and a visual display. Near infrared radiation is particularly suitable for this application. The available light sources for infrared headlamps include halogen bulbs, gas discharge bulbs and light-emitting or laser diodes. Tests on infrared headlamps in a light tunnel showed that they illuminated pedestrians effectively even at a considerable distance. The use of a projection lamp with infrared-transmissive shield enables the production of a headlamp that generates a dipped beam and infrared main beam at the same time. A first concept for an infrared headlamp using infrared light-emitting diodes has been realised as a prototype. For the covering abstract see ITRD E123380.
