Sponsored and prepared by the IES Progress Committee, inclusion of products and technologies in the Report is a prestigious recognition that deems each featured product technologically advanced, innovative and significant to the lighting industry. The IES Progress Committee is mandated to “keep in touch with developments in the art and science of lighting throughout the world, and prepare a yearly review of achievements for the Illuminating Engineering Society.”

“We are honored to receive this recognition by the IES for the TLACS solution, demonstrating our status at the forefront of the industry,” said Pierre Longtin, NYX Hemera CEO. “Our team’s work is dedicated to road tunnel lighting control that enables significant energy savings as well as substantial reductions in installation and operation costs. The TLACS is one of the most technologically advanced tunnel lighting control systems on the market, and has been recently installed in the Carlin Tunnel, Nevada, the first highway rated speed tunnel in North America that is fully lit with LEDs. It is also in operation in other tunnels in Asia, the United States, Canada and soon in Middle East.”

Located in northeastern Nevada and crossing over the Humbolt River, the twin tubes of the 400m-long Carlin Tunnel have recently been part of a $31 million refurbishment program that included enhanced roadway drainage, new concrete entrances, and new lighting system.

Designed with Reno-based PK Electrical for the Nevada Department of Transportation (NDOT), the new lighting system includes new LED luminaires which are specifically designed for tunnel applications; and the TLACS, a sophisticated lighting control system that employs dynamic dimming that responds to ambient light levels on both the inside and outside of the tunnels. Upgrades were completed to the eastbound tunnel in December 2013 and to the westbound tunnel in November (2014).

“When LED lighting is used in road tunnels, an adapted and robust intelligent control system is necessary to be able to get the most out of all the benefits LEDs have to offer. The TLACS’ exceptional increases in energy savings, safety and equipment lifetime will allow NDOT to reduce their operational costs by approximately half during a 20-year lifecycle. This entails dramatic savings over other conventional systems,” said Longtin.

Karen Purcell, Principal at PK Electrical, said: “The design team researched current lighting technologies to evaluate the most cost-effective luminaires for the tunnels. We are very pleased with our collaboration with Nyx Hemera Technologies. The TLACS plays a vital role amongst all the innovative solutions used in the design of the tunnel lighting system. The tunnel will use a lighting control system with the latest technologies that will not only enhance energy consumption and security but also improve operational management.”
