System architecture


telemanagement system

Dark Sky® lighting Management System offers a sophisticated lighting control system, developed from a whole system approach, grouping the entire system into a logical hierarchy, from the city, to the street and control-device level. This ensures that you have a “zoom” to adjust the view over each unit, or at any every level, within the system.

Core of the system, is a point to multipoint mesh networking technology, based on a three tier architecture, incorporating the luminaire controller, the area controller, and centralized web server and MySQL Database.

The luminaire controller, typically installed within the luminaire, facilitates the controlling and monitoring, of each individual luminaire. Each controller or electronic “all in one “ control gear, supplies a dimmable output well suited for High pressure Sodium, Ceramic Metal Halide, Compact HID or LED-based luminaire.

All Dark Sky® devices communicate via the self-discovering, self-healing mesh network, in order to transmit the data between themselves and a segment controller, each segment controller co-ordinates the interaction of manual and preprogrammed commands, switching schedules with up to 400 luminaire controllers and also interacting directly with the centralized web server for data logging and error reporting.

Dark Sky®  Web based operation monitors, controls and manages your lighting installation from anywhere in the world, to the level of a single each luminaire.  From street level, to web level, it’s only a matter of browsing the internet. Locate and monitor your installation in geographic maps, access predefined reports, configure the system, while updating and rapidly embedding into the devices, in remote, new dimming profiles or switching schedules. 

All received information, sent to the central web server, are stored in a MySQL Database and are accessible for reports, or to program a fault rectification, or a load balancing, or to evaluate the lamp life time forecasting.  Where maximum security is essential, specific user firewall rule and VPN functions, provide remote stations, secure authentication and data traffic encryption.

The Dark Sky® segment and area controllers  are installed in the existing control cabinets and enable communication from the central server location to the control cabinets via wireless or wired  communication, without requiring new cabling. The communication is based on both wired and wireless carriers such as: GPRS/GSM; SMS or Wi-Fi; or Fiber optics or Ethernet.
