Lighting solutions for tunnels and underpasses Safe and reliable solutions with high added-value

EVERY TUNNEL IS UNIQUE AND SO IS THE WAY TO LIGHT IT A tailored lighting philosophy Each tunnel is unique, requiring different technical parameters and a bespoke lighting system. The design of tunnel lighting is complex - it needs to take into consideration the location, configuration, use, setting and local standards. We take a custom approach, implementing an environment analysis, extensive photometric studies and cutting-edge and versatile technology. We work closely with our customers, partners and suppliers using proven design and co-creation processes. From the photometrical study, integrating...

A complete package of services We deliver more than luminaires - we also provide our own Advanced Tunnel Solution (ATS) to effectively manage your lighting network, together with a range of services including installation, commissioning and optimisation.

Technology-driven design As a long-standing tunnel lighting expert, Schreder puts all of its know-how and expertise into developing new smart solutions to enhance the tunnel experience and facilitate your day-to-day challenges. Building Information Modeling A technology to improve quality and reduce operating costs Over the decades, paper drawings have been replaced by digital drawings, and now virtual reality comes into the tunnel design. Our design teams work with the latest technology, including Building Information Modelling (BIM) files - digital models of our luminaires - integrate the customer’s...

A long lasting experience As pioneer in tunnel lighting, Schreder 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...

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...

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 A strong and uniform visibility all the way through every tunnel zone 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 guidance and visibility inside the tunnel. Emergency management If...

Maximise savings and optimise time Save time City life is more and more demanding and therefore requires quick and efficient solutions. Our tunnel lighting is designed to answer those daily challenges: • Tool free luminaires for a fast on-site response • Smart cables and quick-on connectors to ease and speed-up installation • Advanced control solutions to remotely manage the installation at all times Reduce maintenance operations Our luminaires are built to last and withstand the harshest conditions: • Advanced electrical components to significantly minimise operating costs while providing high...

The right light where, when, and how it is needed 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...
