The roundabout is a traffic situation that affords a specific lighting concept. Vertical illuminance should ensure a high level of visibility with respect to vehicles, cyclists and pedestrians, and a sufficient glare-free and uniform illuminace must be available for horizontal surfaces, i.e. paths and roadways.
This combination of horizontal and vertical illuminance is achieved with a combination of a secondary reflector system in the centre of the roundabout and an arrangement of luminaires in the peripheral areas with an efficient specular reflector technology with a plane glass enclosure to minimise glare.
With the use of metal-halide lamps an excellent colour rendering is ensured. Furthermore the light of a metal halide lamp contrasts strongly with that of approaching roads, resulting in improved visual awareness.
