Lighten up with Nyx Hemera’s ILCAM2

Nyx Hemera Technologies says its ILCAM2 photometer - part of the company's TLACS (tunnel lighting addressable control system) solution – helps cut energy consumption

Enclosed in a rugged painted stainless steel container, the ILCAM2 photometer runs off existing power lines in road tunnels and can help improve driver safety.

Nyx Hemera Technologies says that its new ILCAM2 power line illuminance photometer can help reduce tunnel lighting energy consumption and boost green credentials.

The ILCAM2 - part of the TLACS (tunnel lighting addressable control system) solution - measures the level of illuminance within road tunnels and underpass bores to ensure interior light levels are continuously maintained to improve lighting conditions for drivers.

The ILCAM2 is used in road tunnels within the TLACS-EM system and in underpasses with the TLACS-U. It sends the illuminance values to a lighting control cabinet using power line communication on existing power cables.

The ILCAM2 uses a highly light-sensitive photocell – silicon photo diode - filtered to provide a spectral response close to that of the average human eye in order to react to changes in light levels within the tunnel environment. The unit measures the illuminance over a standard range of 0-20,000 lux (maximum), which can be scaled to meet user requirements.

The unit is contained in a rugged painted stainless steel 316 container and has an operational temperature range from -30ºC to +70ºC. It is also CIE and IES approved or measurement technology.

Power line communication doesn't require the installation of additional control wires for control and monitoring. It uses the existing powerline cables. This means important savings on the installation time, on wires and connectors and on maintenance of the lighting system.

“With over 30 years in developing power line applications, it was obvious for Nyx’s team to improve its ILCAM with a power line version,” said Pierre Longtin, president of Nyx Hemera Technologies, based in Quebec City, Canada. “The ILCAM2 was created mainly for long tunnels as it helps save on installation time, related manpower and the cost of cables that can run for miles in such infrastructure.”

    High performance markings are among the safety products used to guide traffic safely, but they must be tested and checked. Patrick Smith reports. Road construction zones, zebra crossings, tunnels and areas with frequent fog are particular focal points with regard to road user safety. This is why manufacturers, authorities and contractors are always eager to use innovative road markings and special studs or, where necessary, lane control devices to assist both drivers and pedestrians in all conditions, parti

The massive physical presence of the asphalt plants could be seen from a distance, right across the showground, particularly the 50m-high machine Benninghoven had opted to exhibit. However, other plant systems from rival firms Ammann, Lintec and Marini, as well as Turkish company E-MAK, c
