Energy Efficiency – Innovative Lighting Management
Digital Managed Lighting Systems
Digital Managed Lighting Systems are designed to provide optimum lighting conditions and maximum flexibility for office lighting projects. They offer benefits when compared to stand-alone lighting control options and time-of-day lighting management systems and can provide a fully integrated lighting and lighting management scheme far more effectively than similar specification luminaires.
The enhanced performance of these systems is made possible by using communicating presence detectors. Information on the current state of occupancy within the building runs through the low voltage bus network. Physical barriers such as walls and partitions do not impede this process. The systems can be used to compensate for daylight automatically to ensure a constant lighting level and can detect arrival or departure from an area to reduce unnecessary usage.
Presence Detection Systems
Presence detectors respond to the movements that occur when an area is occupied. Personnel entering a controlled area automatically activate the lighting and subsequently sustain it by even the smallest movements they make as they go about their normal activity. When they leave, the lights automatically switch off, and will come on again only when the area is occupied once more.
Detectors incorporate both an adjustable off delay and photocell which should be set to suit local conditions. The photocell may hold lights off or, when used with suitable ballasts, allow the luminaires to dim and brighten according to the level of natural light.
Excor Controls (other suppliers are of course available) offer ranges in these areas that are worth further investigation.
