Building Information Modeling Technology to improve quality and reduce costs
Over the decades, paper drawings have been replaced by digital drawings, and now virtual reality comes to tunnel design. Our design teams work with the latest technology, including Building Information Modeling (BIM) files - digital models of our luminaires integrate the customer’s virtual tunnel environment to visualise and prepare the future installation. Based on customer requirements, we can provide several 3D models of our tunnel luminaires with key data such as overall dimensions and material. Customers can then make well-informed decisions faster.
Depending on the project phase, we can provide different levels of details . In the preliminary phase, basic details such as global dimensions, weight or materials will be given. As the project progresses, more details (fixation type, IP, IK, cable diagram, etc.) will be supplied.
Consistency: one single platform to combine multiple models from different partners Convenience: a unique source of shared information Anticipation: a virtual build to prepare the installation and anticipate potential errors Savings: a possibility to correlate planning and costs
A long lasting experience
A pioneer in tunnel lighting, Schréder has designed and delivered lighting solutions for more than 1,000 tunnels worldwide, from Mont Blanc in France to Queens Midtown Tunnel in USA. Your challenges make beautiful stories
Queens Midtown Tunnel – New-York (United States) The Queens Midtown tunnel is one of the best known and recognisable motorway tunnels in all North America, connecting the Borough of Queens to Manhattan. In October 2012, floodwaters from Superstorm Sandy damaged the tunnel’s architectural, mechanical and electrical components. We brought our tunnel expertise across the channel and provided a safe and sustainable lighting set-up.
Loi Tunnel – Brussels (Belgium) The Loi Tunnel is one of the main entrances into Brussels city centre. It brings motorists onto Rue de la Loi, which is home to many European institutional buildings. As part of a large-scale renovation, the lighting was replaced. To ensure a safe and comfortable environment for the numerous motorists who pass through it every day, we supplied a lighting solution that enhances the aesthetic quality and safety of the route. It creates a vibrant yet relaxing landscape for a pleasant driving experience.
Velser Tunnel – Velsen-Zuid (Netherlands) Built in 1957, the Velser Tunnel was closed by the Dutch motorway authority for 9 months in 2016 to undertake extensive renovation and repair work. For this tunnel, we supplied a complete lighting solution, integrating luminaires that provide optimal visual comfort while significantly reducing energy costs, and an intelligent control system that enables the tunnel operators to remotely manage the whole installation.
YOUR MOBILITY Tunnels require lighting that enables drivers to quickly adapt to an enclosed environment so they can easily identify possible obstacles and travel without reducing speed. Excellent visibility and high visual comfort is key to ensure smooth mobility. Focus on your visibility
Our luminaires have been specifically designed with optics that optimise luminance for tunnel environments. They provide the correct levels of lighting with excellent visibility to enable drivers to avoid the black hole effect at the tunnel entrance and any glare phenomenon at the exit. Photometry for each application We have various photometrical engines capable of generating wide photometric distributions to meet all types of applications while maximising energy savings. Our LensoFlex® platforms have been designed with high-power LEDs that can be associated with a large variety of optics that withstand high currents for a maximised lumen output. Lenses, reflectors and collimators Some projects need precise lighting features due to a particular tunnel environment or some local standards. We deliver the photmetrical solution that provides the most optimum result, whether this requires lenses, reflectors or collimators to ensure a comfortable and glare free experience.
of robust materials and benefit from long-lasting components ensuring performance 24/7 in the long term. Furthermore, our tool free solutions enable fast on-site repairs and maintenance interventions if necessary. Smart cabling and quick-on connectors also speed up any field interventions by avoiding any wiring or mounting issues.
Less maintenance to minimise disruptions and closures Tunnel maintenance activities might cause some closures, causing delays and disruption to traffic and so, city life. An unexpected 15-minute tunnel closure is estimated to cost €15,000. Tunnel operators need reliability. That is why our tunnel solutions are designed to reduce maintenance to a minimum. They are made
YOUR SECURITY A good tunnel is first and foremost a safe tunnel. The lighting should make motorists feel like they are driving on the open road. It must ensure that they enter, transit and exit the structure in complete safety and comfort
Light for safety High visibility throughout the tunnel ensures a safe journey. As security is a priority, our luminaires are equipped with state- of-the art optics that deliver excellent uniformity on the road and walls, as well as optimised contrast levels for perfect visual If an accident occurs, our lighting solutions safely guide motorists to emergency exits. Coupled with our Advanced Tunnel Solution (ATS), our luminaires automatically switch to an emergency scenario to help users evacuate the tunnel. At the same time, this control system can send commands to the central control point to close the tunnel entrance or reduce the speed limit. guidance and visibility inside the tunnel. Emergency management
MAKE A DIFFERENCE
Light uniformity has a huge impact on drivers’ visibility and safety. Without a clear view, they cannot anticipate potential dangers. By studying your tunnel environment, we can propose a highly uniform lighting installation to guarantee a higher level of security.
Monotony, a threat for drivers security Tunnels are designed to be as straight and uniform as possible. This concept might quickly become monotonous and have a negative impact on drivers’ behaviour. Accidents occur when motorists tire and do not focus on the road anymore. A vibrant and customised lighting installation creates a unique ambiance which catches the driver’s eye and enhances the tunnel experience. Our LEDs and optics can be customised for each tunnel installation. Give your tunnel an unique identity with a dynamic lighting scenario to provide a safe but unforgettable experience.

The right light where, when, and how it is needed YOUR ENERGY
Generate energy savings and improve safety Each tunnel zone requires a different luminance level. This level should be high at the entrance and in the threshold zone and then decrease inside the tunnel as the eye adapts. These requirements generate an ideal lighting curve called the CIE curve. The more your lighting installation follows this recommended curve, the less spill light there will be and the more efficient the installation will be. At Schréder, our advanced luminance calculation software analyses all aspects of your tunnel environment to provide you with the right luminance level in all tunnel zones. We deliver lighting systems to improve safety, reduce energy consumption and generate savings.
During our study, we calculate the number of luminaires to be installed in the tunnel and their orientation to create a curve as close as possible to the CIE normative curve for an efficient and economical light installation.
