Motion Sensing Street Lighting
Comlight gives you motion based lighting; when and where it is needed. Our lighting system is activated by an object’s movement, literally lighting up it’s path ahead.

Safety through good lighting, when and where it is needed.

Comlight, a Norwegian company, has developed a patented system that reduces the wasteful consumption of energy without reducing safety. We have called this ”Motion Sensing
PLACEMENT OF OUR MOTION SENSING STREET LIGHTING SYSTEM
Street Lighting”, a radar lighting system that is automatically activated by movement detected in it’s detection area. This system saves large amounts of energy.

Maximal safety, minimal energy.

For us at Comlight, the

and public spaces when not in use.
ENVIRONMENTAL SUSTAINABILITY Changes caused by humans are disturbing the delicate, vital balance of our ecosystem. A steady increase in light pollution is undoubtedly playing a role. Long before night falls, the lights are lit. This is completely unnatural. According to researchers it affects animals’ behaviour and may in time cause serious disturbances to the ecosystem. As a rule, when the sun goes down the light levels should do the same. This is good for biodiversity, good for the climate and good for the environment.

Example 01)
Example 02)
A road with the pavement close to the light pole will need a detection area setting positioned to cover movement on both the road and the pavement.
A light pole with the pavement on the opposite side of the road, will need another detection area setting, positioned to detect movement on the opposite side of the road as well. 9
GPRS
Remote access. GPRS Allows remote access to both parameter settings and retrieval of information. Remote retrieval of statistical data, e.g. Hours the luminaire has been on high intensity (bright) Hours the luminaire has been low intensity (low) Number of moving objects detected in a given time-frame

COMLIGHT PARAMETER SETTINGS The parameter settings can control for example: • Lighting at road junctions, e.g. all lights at the junction illuminate at high intensity when pedestrian or vehicle movement is detected • The light intensity of individual luminaire (from high to low) • Settings for rush-hour traffic, e.g. temporary high level intensity at pre-set times of day • Temporary adjustments of the light intensity at pre-set times of day, e.g. during rush-hour traffic
