Nyx Hemera, also based in Quebec, Canada, has signed a contract with ProdExport Technologie for manufacture of the main component of its intelligent Tunnel Lighting Addressable Control System (TLACS).
The contract is for the production of the Local Product Controller, which controls and monitors each light individually thereby bringing major savings in road tunnel lighting energy consumption and overall operating costs.
"This contract with ProdExport allows us to deliver world class products for harsh environments," said Pierre Longtin, Nyx Hemera President and Chief Executive Officer.
"The collaboration will also allow Nyx Hemera to remain competitive for price and quality in order to stand out against other providers, and introduce a new version of the LPC in the North American market."
Bernardino Camba, President of ProdExport, said: "We are proud to actively participate in the carrying out of a high end sustainable development solution such as Nyx Hemera's TLACS."

The TLACS system allows for individual addressing of each luminaire, which helps to adjust brightness in tunnel entrances according to exterior lighting. TLACS also features a preventive maintenance program, which generates complete diagnostics, such as the age of each luminaire. The system is marketed worldwide by Nyx Hemera Technol for both tunnel refurbishing projects as well as new developments.
TLACS was installed as the lighting control system for the 16,000 luminaires on the 12km six-lane tunnel section of the Kallang Paya Lebar Expressway in Singapore. It also features in a number of tunnels across the USA and Canada, including three tunnels built as part of the new Mitchell Interchange in Milwaukee.
One of the system's features is that it helps manage the lighting stages of the tunnel luminaires to reduce the so-called black hole effect at the entrances and provide a smooth transition to daylight at the exits (Fig 1).
ProdExport specialises in the production and assembly of electronic finished products and printed circuit boards in Asia for North American companies.
