DID YOU KNOW ?
Tunnel lighting is the opposite of street lighting.
In contrast to street lighting, the brighter it is outside, the greater the need to illuminate tunnel entrances to avoid the “black hole” effect. On the other hand, at night, the darker it gets, the more it’s necessary to dim tunnel entrances to reduce the glare created by over-lighting.
As two-thirds of accidents occur at tunnel entrances, lighting plays an important role in road user safety. An intelligent control system that adjusts to outside light levels is therefore essential. TLACS is the type of system that Nyx Hemera Technologies has been installing in nearly 150 tunnels around the world for the past 15 years. For further information: https://www.nyx-hemera.com/en/media/
