Functional principle
Like our well-known handrail system, the new singleLIT is designed for emergency lighting along the tunnel escape route and is suitable for use in safety lighting systems in accordance with
EN 50172 and TSI-SRT (Technical Specification for Interoperability - Safety in Railway Tunnels).
The singleLIT was developed based on the specifications of DB Netz AG and strictly follows the sustainability principles of the Rhomberg Sersa Rail Group.
Therefore, only highly durable materials are used, and the energy consumption has been optimized to approximately 4W.
The luminaire features innovative light guidance using LED lenses and specially designed light-emitting surfaces on the light head.
This ensures that the light is perfectly directed onto the escape route in the tunnel.
