Emergency exit lighting in tunnels

The emergency exit lighting is designed to indicate the escape door and to support aid rescue. The escape door is signalised by 3 permanent lighting LED modules on both sides. The modules are installed directly onto the concrete wall or on a straight cable tray or fitted to the tunnel radius. The brightness of the modules is adjustable via the control unit. The changeover from daylight to night intensity (and vice versa) can be carried out by an extern signal or by a brightness sensor. The power supply can result from the existing mains supply or from an extern solar station.
