TUNNEL LIGHTINING AND ELECTICITY

Tunnel Lighting: A Highly Technical and Critical Application

Tunnel lighting is arguably the most technical and critical application among all lighting solutions. Due to the inherent risks of road traffic and the constraints imposed by a completely enclosed and isolated environment, successfully illuminating a tunnel's surface is an extremely challenging task. It is not sufficient to merely light different zones within a tunnel uniquely; seamless transitions between these zones are equally essential.

Although there are strictly defined rules regarding glare and illumination levels, meeting these requirements is only possible by combining precise design with the right product. With decades of experience and over a hundred completed projects, TME GRUP’s expertise and capabilities in tunnel lighting are unparalleled.

TME GRUP, driven by a dedicated team, is the one-stop solution for executing a successful tunnel lighting project, contributing to solving the complex transportation needs of modern cities. Each tunnel project is approached uniquely, starting with meticulous design and continuing with the integration of the right products.

The versatility of TME GRUP’s product capabilities allows for fine-tuning of optics to ensure accurate lighting across various tunnel zones. The careful selection of materials and components ensures the durability of products under harsh environmental conditions. The integration of state-of-the-art, energy-efficient control systems adds the finishing touch to each project.

Increasing Need for Tunnel and Underpass Lighting

With expanding transportation networks and growing traffic density, the number of tunnels and underground passages is steadily increasing. Tunnels are often preferred as transportation links to shield cities from the visible effects of traffic or to preserve the natural environment without deformation.

Due to their enclosed structure, tunnels impose significant constraints on maintenance access to any point within them. Furthermore, tunnels are subject to highly damaging atmospheric conditions. Therefore, the lighting systems used in these areas must be highly reliable and, ideally, maintenance-free. At this critical juncture, tunnel LED lighting systems provide the most robust solution to meet these needs.

Objectives of Tunnel Lighting

The goal of tunnel lighting is to ensure safe and comfortable traffic flow during both day and night at a brightness level that is no less than what exists in the surrounding areas outside the tunnel. This applies to traffic moving at the "Tunnel Lighting Design Speed" as it approaches, passes through, and exits the tunnel. While tunnels inherently impose speed limitations, the primary aim is to maintain uninterrupted traffic flow, regardless of speed.

Importance of Adaptation to Lighting Conditions

This requirement is particularly critical during daytime when the human visual system must adapt from bright to dark environments. A poorly or inadequately lit tunnel entrance can create a “black hole effect” in the driver's field of vision. This effect triggers an instinctive reflex to suddenly reduce speed, potentially leading to severe accidents.
