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.
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 RFL LIMAS HUB3 G2 GPS SIM, which enables central control and monitoring of the light fittings from anywhere in the world.
With this system solution, the luminaires can be programmed and read out on site in the field using a USB dongle and Windows PC/tablet. The luminaire parameters such as dimming level, run-on time and behaviour in the event of motion detection are stored in the radio controls/HUBs. The luminaires can be operated without a connection to the USB dongle. Both items also each contain a photocell for a twilight switch. Here, one HUB is defined as the master brightness sensor in the field, which transmits the correspondingly measured brightness value to all other HUBs in the field (slave). At least one GPS SIM HUB is required for time-accurate switching via the light management system. This HUB supplies the integrated GPS antenna and the connection to satellites in the neighbourhood the exact time and forwards it to neighbouring HUBs via radio. HUBs via radio. |  |
With this system solution, the luminaires can be programmed, read out and monitored remotely using cloud access via any Internet browser and any operating system ❺. The GPS SIM HUB ❶ uses its integrated SIM card ❷ to wirelessly connect neighbouring HUBs ❸ to the cloud ❹. The GPS SIM HUB uses the integrated GPS antenna and the connection to satellites in the vicinity to provide the exact time and forwards this to neighbouring HUBs via radio. The exact position is also recorded using satellite technology. The luminaire parameters such as dimming level, run-on time and behaviour in the event of motion detection are stored in the radio controls/HUBs. The HUBs of the luminaires therefore continue to work independently even without a connection to the cloud. Both items each contain a photocell for twilight switching. Here, one HUB is defined as the master brightness sensor in the field, which transmits the correspondingly measured brightness value to all other HUBs in the field (slave). |  |
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 passes an RFL luminaire with HUB and motion sensor, this is detected by the motion sensor and, depending on the programming, the luminaire switches from background level 10% to 100% illuminance with a defined follow-up time, e.g. 1 minute. Neighbouring luminaires can be linked via the light management system in order to set up a leading light. As soon as a motion sensor of a luminaire detects an object in conjunction with a radio control system, the neighbouring luminaires in the street are also switched to a higher lighting level via radio. |  |
