The challenge

Illuminated tunnel entrance and exit

Fluctuating light conditions

Installation companies, operators, and lighting system planners must illuminate tunnels uniformly in accordance with CIE88 and control the intensity of the lighting depending on the situation. The traffic volume and emergency situations that may occur have an impact on the correct lighting level. In order to counteract the risk of accidents, especially when vehicles are entering the tunnel, the lighting conditions need to be adjusted sensitively to the increasing darkness.

Solution

Energy-saving and demand-oriented tunnel lighting

With the predefined control cabinet solutions, you can configure your entire lighting system quickly and easily, without any programming effort. Combined with the versatile and robust QPD installation system, Tunnel Lighting Advanced ensures fast installation and maintenance procedures. This enables you to extend maintenance intervals and save operating costs.
The intelligent control system ensures the ideal lighting level throughout the entire tunnel by incorporating parameters that affect the light intensity. In addition to the measured luminance at the tunnel entrance, the current traffic speed and traffic density are also taken into account, for example. Since only as much light is generated as is needed at any given time, the energy costs are lower and the service life of the LED lights is longer.

Plug-and-play installation system
Phoenix Contact delivers the power line and bus line preassembled to the construction site. Each cable in your tunnel project is already precut, fitted with the necessary connectors, and marked. The flexible and robust QPD installation system with proven QUICKON fast-connection technology ensures rapid and error-free installation of the lighting.
Plug-and-play installation system
Control system
The preconfigured control cabinet houses a comprehensive control system that can be used to easily manage all tunnel lighting parameters remotely. Integrated interfaces enable easy data exchange with the higher-level tunnel control system. The control system is available in two versions: with classic DALI control or with Phoenix Contact’s own extended Lumgate control. Integration into the control system takes place as needed via a selection of standard protocols.
Control system
Sensor technology
Sensors are located above the tunnel entrances and are connected to the controller via analog inputs. The sensors measure the luminance at the tunnel portals, which means that the entrance area can be made brighter or darker depending on the ambient brightness.
Sensor technology
Activation electronics
The intelligent Lumgate luminaire control unit is used to couple the central control system to the tunnel luminaires. It is suitable for installation in driver boxes or directly in the luminaire. The control system is available in two versions: with classic DALI control or with Phoenix Contact’s own extended Lumgate control. Integration into the control system takes place as needed via a selection of standard protocols.
Activation electronics
Tunnel luminaires
Based on various tunnel parameter signals, the control system enables remote dimming and switching as well as comprehensive diagnostics of all networked luminaires.

Power distribution
The TAP (Tunnel Application Power) boxes from Phoenix Contact have been specially developed for safe, fireproof, and simple power distribution in tunnels. Starting from the main distribution, the TAP box supplies the lighting systems with power. This protects the main distribution from short circuits. Extremely high functional integrity means ongoing availability is guaranteed even in emergencies.
