Wireless light management
Our light management system LIMAS allows a needs-based, extremely efficient and comfortable lighting control on streets, squares and cycle paths!
Intelligent components built into the luminaires automatically generate a wireless network to communicate with each other. As desired or when motion is detected, the light fittings can either turn up a dimmed lighting level or return to a pre-set background level.
When does it make sense?
- General achieve of energy cost savings by needs-based lighting (Light on Demand)
- Central control and monitoring of each individual luminaire without additional wiring
- Cost control by energy consumption metering
- Changing usage profiles, e.g. temporary city centre events (Christmas market, festivals etc.), which temporary different levels of lighting
- Different levels of lighting in some city areas (e.g. residential areas, industrial zones, old town districts, conflict zones or social hotspots)
System versions
The light management system LIMAS is available in two system versions. Choose either the version with USB dongle, which enables control and monitoring of the light fittings on site, or the version with gateway, which enables central control and monitoring of the light fittings from anywhere in the world.
- Each luminaire is equipped with a controller that communicates with each other and transmits commands via an automatically organized mesh network (2.4 GHz radio network)
- Control (programming of the controller) and monitoring of the light fittings takes place on site via radio using a PC and USB dongle
- Encrypted radio network
- A maximum of 250 luminaires can be controlled and monitored per USB dongle
- Each luminaire is equipped with a controller that communicates with each other and transmits commands via an automatically organized mesh network (2.4 GHz radio network)
- Gateways that are installed in control cabinets within radio range of the luminaires communicate with a server via mobile radio or Ethernet as well as the internet
- Encrypted radio network
- Server collects the data of the gateways and provides all features via an intuitive web interface. This enables the light fittings to be monitored, checked and controlled
- A maximum of 250 luminaires can be controlled per gateway. By combining several gateways, the number of luminaires that can be integrated in one system is not limited
Features
The LIMAS system offers a variety of features for needs-based lighting control and for extensive monitoring of the light fittings. Thanks to the intuitive user interface, system settings can be easily adjusted and reports can be called up quickly.

If a road user enters the road, the motion sensors, integrated (LMS IR) or retrofitted in the light fittings (RFL accessory), detects the movement and the dimmed light fittings automatically adjust to the programmed lighting level. The signal is transmitted wirelessly from light fitting to light fitting, so that all light fittings increase their lighting level too - light accompanies the road user dynamically. After a programmed hold period, the luminaires automatically return to the pre-set dimming level.

AVAILABLE LIMAS VERSIONS
- LMS - Standard features of the selected system version
- LMS IR - Standard features of the selected system version + motion detection via PIR sensor
- LMG - Standard features of the selected system version + time, date, parameter and position monitoring via GPS
Further versions and combinations on request.
At the customer's request, dimming profiles can be factory-programmed. Time-dependent dimming requires at least one light fitting in LMG version in case of USB dongle system version.
