The Queen-Creek Tunnel is the first tunnel in Arizona to install technology for lighting control, said Pierre Longtin, president of Nyx Hemera. The $3 million renovation of the 400m tunnel, built in 1952, is part of ongoing efforts to upgrade the US state’s road network to improve security and luminaire efficiency.
The project involves removal of the interior lighting, installation of an LED lighting system with an intelligent control system, replacement of the exterior lighting at both ends of the tunnel, the adaptation of the current electrical control building and the cleaning of the walls and ceiling of the tunnel.
The Tunnel Lighting Addressable Control System is being used in tunnels also in Singapore, Europe, the Middle East, South America and Canada with LED and HPS lighting systems.
Holophane, based in the US city of Newark, provides lighting systems for commercial, industrial, emergency and outdoor applications.
