    No more clash between standard lamp mast and cable stays

Smart LED solution

Light-Emitting Diodes (LED) solutions have become more robust and compact and can now be fully integrated into the cable ducts, transforming any cable-supported bridge into a multi-pixel, remote-controlled LED display stand. The low-consumption LEDs are interconnected by electrical wires and incorporate all the electronics required to transmit power and instructions. The system is compatible with cables over 300m. It can also be installed on an existing cable-supported structures using half-shell assemblies. Applications: cable-stayed bridges, suspension bridges, extradosed bridges, stadiums.
  • Resistance to dust and rainwater (IP66)
    Durability exceeding 100 000 working hours
  • Various LED shapes,
    from 300 mm bar modules to 40 mm round pixels.
    Different layouts available.
    Light intensity adjustable from 0 to 100%.
  • Remote control system.
