This article gives an account of the public lighting systems employed at Wuppertal. The author describes the 20-metre high lighting columns which were installed on the main road in 1958 for aesthetic reasons. The columns were spaced at 55-60 metres and carried five reflector lanterns. Details are given of the 30-metre masts lighting at the Sonnborn interchange where two main roads, several city roads, a suspension railway and a 4-track railway section intersect. The system was designed to facilitate direction finding and improve traffic safety. It consists of 30-54.5 metre high columns made from pre-stressed concrete erected at intervals of 70-90 metres which, in conjunction with an efficient lighting system, attained a road surface luminance of 2cd/m2. As regards general street lighting resistance to corrosion are factors to be taken into account. The gas lamps have been replaced by electric lamps because of the higher operating costs of the former and an audio-frequency power line carrier system introduced in the city's high voltage grid to avoid the high costs of laying additional cables. Details are also given of the lighting of pedestrian precincts and motorway interchanges. /TRRL/
