Lighting

In the solution examples, DALI is the standard through which luminaires, sensors and switches are individually addressed and controlled. With B.E.G.’s LUXONET, a DALI gateway scans the line and automatically integrates existing DALI devices, so the system integrator can check the installation without a site visit. The LichtWART module connects to power supplies with a DALI bus and shows the status of all luminaires and converters on a dashboard.

Illuminated advertising can be monitored with a retrofittable IoT module that records the status of the lights and reports it via the cellular network. With LichtWART, a light sensor adjusts brightness to the surroundings, and in the event of a failure an email goes to staff or service technicians, even during a power cut thanks to a backup battery. The smart.click system from IOX and Projektunion also monitors the power consumption of billboard lighting via Narrowband IoT.

Energy monitoring shows when and where systems such as lighting consume electricity, including outside opening hours. In a retail network with more than 600 sites, the PSsystec IoT Energymonitor reads existing meters non-invasively, and installation usually took around two hours per branch. The data reveals load peaks and unnecessary base loads of energy-intensive systems such as lighting, refrigeration and heating. Energy costs fell by 5 to 10 per cent.

A lighting control system uses occupancy sensors to switch or dim the lighting depending on whether a room is in use. In Société Foncière Lyonnaise’s BIOME building in Paris, presence detection and brightness regulation are part of the DALI lighting control via the building management software. At Merck Real Estate, lighting status flows into the CREM SOLUTIONS smart building platform together with space occupancy, temperature and indoor CO₂ levels in order to save energy and space.
