Central Management Systems
Energy Saving Street Lighting
Within the lighting industry as much as any other sector, the move is very much towards saving energy and reducing carbon emissions.
Whilst our designs are traditional, our street lighting uses the most up to the minute smart ballasts and other electronic devices to deliver optimum operating and energy efficiency.
We would be pleased to advise you on the best technology for your particular needs. Options range from stand-alone solutions to group managed and networked systems. Overviews of some of these are shown here – for more detailed descriptions, please visit the ballast manufacturers’ own websites.
WiMAC (Wireless Management & Control)
This type of system give you control over a lighting network and as such via a web based/internet access enabled system allows the user to run reports and control individual and group installations. The system will allow the dimming of street lights along with monitoring energy use, the system will also report on failed and failing lamps eliminating the need for ‘scouting’.
The system is simple in how it operates and for the network it follows the following protocol, which parts of are titled differently depending upon organisation using them.
Manufacturers:- Harvard, Zodion
User Each manufacturer will have their version of the CMS (Central Management System) which is based around the capabilities of their products.
|
Host This part of the system communicates with the web based/internet access enabled application and the branch/collector, using the GSM network, to exchange information. |
Collector The branch/collector sends and receives information and data from each node within its range, typically a 1km radius, using the WiMAC protocol. This information is fed back to the trunk/host and in turn back to the user. |
Node The node is located within the luminaire and is powered from the ballast. The node sends information collected by the ballast to the branch/collector which then sends it down the line to the trunk/host and then to the user. |
Benefits
- Remotely monitor & control luminaires
- Set up and deploy a dimming profile
- Set up and tailor group profiles
- Monitor energy usage
- Reduce Carbon Emissions
- Reduced maintenance costs by eliminating scouting
Dali (Digital Addressable Lighting Interface)
This system works in a similar fashion to the WiMAC system but follows a different set of protocol. Using a meshing system and the Zigbee Protocol you can potentially connect more luminaires with a lower capital investment over a wider area.
Manufacturers:- Philips, Mayflower , Telensa , ASK

Back Office This part of the system communicates with the web based/internet access enabled device using the GSM/GPRS networks, to exchange information. |
Master The master sends and receives information from nodes which use a Zigbee meshing system allowing the transmit/receive range to be far greater than that of the Wimac Branch Node/Collector. This information is fed back to back office and in turn back to the user. |
Node The node is located within the luminaire and is powered from the ballast. The node sends information collected by the ballast to the master which then sends it down the line to the back office and then to the user. |
Benefits
- Remotely monitor & control luminaires
- Set up and deploy a dimming profile
- Set up and tailor group profiles
- Monitor energy usage
- Reduce Carbon Emissions
- Reduced maintenance costs by eliminating scouting
