will be featured in an episode of Innovations with Ed Begley Jr., airing on June 17th, 2016 at 7:30 nationwide on Discovery Channel. International distribution will be through Voice of America within the following weeks.
The show will feature the Interstate 80 Carlin Tunnels’ state-of-the-art lighting system controlled with TLACS which the Nevada Department of Transportation installed in 2014 as part of the Carlin Tunnels Improvement Project in northeastern Nevada.
The first such system to be used in a freeway tunnel in North America, the lighting system automatically and gradually dims or brightens lighting to match outside lighting conditions, instead of maintaining one consistent light level in the day and night. By more closely matching the outside light, the lighting system makes it easier for drivers’ eyes to adjust while traveling in the tunnel, ultimately improving driver visibility and safety.
Using 774 LED luminaires, as opposed to the previous 1219 high pressure sodium luminaires, the system is also much more environmentally and budget friendly. Over the next 20 years, the lighting system is anticipated to save more than nine million dollars in maintenance and replacement costs.
Pierre Longtin, President of Nyx Hemera Technologies said “Lighting a tunnel is complex and expensive. It is the most consuming equipment in tunnel operations: a 1 km tunnel (0.6 mile) needs as many lumens as a 20 km (15.5 mile) roadway.. Tunnel lighting and the TLACS features and its positive impact on energy consumption, equipment’ lifetime and remote control and monitoring will also be explained in the show segment”
