Sensors and lighting control from Autani and Keilton: presence, daylight and schedules control each luminaire individually – from a single room to a networked site.
The most economical luminaire is the one that is off.
An LED retrofit lowers consumption per operating hour. Sensors lower the operating hours themselves. Together the two work far better than either on its own – and in areas with changing use, the second step is often the bigger one.
Rack aisles, ancillary rooms, stairwells, car parks and halls on shift work often stay lit right through, although for long stretches nobody is working there. That is exactly where light management comes in.
What the law expects
Control is no longer optional.
The German Building Modernisation Act (GModG) transposes the European buildings directive into national law and increasingly requires demand-based control of building services in non-residential buildings. Lighting is part of that.
That is why our luminaires are sensor-ready: they are prepared to take sensors, including later on, once the project is ready for it.
Experience the sensors
Light only where where someone is.
A person walks down the racking aisle, then a forklift drives past. Sensors switch on only the nearby luminaires.

Dashed: the detection area of one sensor. The luminaire switches on as soon as someone is inside it and stays on briefly afterwards (run-on time). An illustration, not a measurement. The actual saving depends on usage, run-on time and base light.
System architecture
Four levels. One system.
The luminaire.
A sensor and a small controller sit in or on the luminaire. Every luminaire can then be switched and dimmed individually. The technical term is luminaire level lighting control, LLLC for short.
The zone.
Luminaires, sensors, switches and accessories in an area form a Bluetooth Mesh network. Every device relays radio signals, so the network carries itself. A zone can hold around 100 nodes.
The gateway.
A gateway turns the local zone into part of the wider installation: schedules run in sync, consumption data is collected, and several zones grow together.
The central controller.
The Autani Manager with the EnergyCenter software brings everything together: lighting, sensor data and further building services on one interface, graphically on the floor plan, with analysis over time.
Not every project needs all four levels. Many installations stay on level two for good – the central controller is only added once several areas or sites are meant to grow together.
What is controlled
Four rules that save electricity.
Presence.
A PIR or microwave sensor detects whether anyone is there. The luminaire switches on and, after a set hold-on time, goes off again or drops back to a base light level.
Daylight.
A light sensor measures the brightness on the spot. If enough daylight comes through windows or roof lights, the artificial light is dimmed down – often without anyone noticing.
Time.
A real-time clock in the zone makes sure schedules run identically everywhere. For outdoor installations there is the astronomical version, which knows sunrise and sunset.
Zones.
Luminaires are combined into groups: one rack aisle, one hall bay, one office wing. Every group gets its own rule without needing its own wiring.
Components
Fourteen building blocks. Each with a datasheet.
Sensors for halls and offices, controllers for the luminaire, gateways, time modules and control devices. Every component with technical data and a datasheet to download.
Light management means the lighting does not burn at full output all the time but responds automatically to how a space is actually used. Sensors detect occupancy and daylight, and a control system then switches and dims individual luminaires or whole areas.
What does LLLC stand for?
LLLC stands for Luminaire Level Lighting Control. Every luminaire has its own sensor and controller and is regulated individually, instead of a whole group being switched together.
What is Bluetooth Mesh?
Bluetooth Mesh is a radio network in which every device relays the signals of the others. The network therefore reaches further than a single radio link, and no additional control cable is needed between the luminaires.
Can sensors be retrofitted?
Yes. Because the components communicate by radio, the control system needs no additional cabling. That makes retrofitting existing buildings considerably easier than with wired systems. Battery-powered sensors and switches need no cable at all.
How much extra electricity do sensors save?
That depends on use: the more irregularly an area is used, the greater the effect. The potential is highest in rack aisles, ancillary rooms and car parks, and lowest in production areas that are staffed continuously. A reliable figure only emerges from the operating hours of your own installation.
Does this work with existing luminaires?
That depends on the luminaire. It needs a dimmable driver with a suitable interface, for example 0–10 V or DALI. Our series are designed sensor-ready. For third-party luminaires we check case by case.
Who plans and commissions the system?
Choosing the components and dividing the site into zones is part of the lighting design. TRiALED supports selection, planning and commissioning; the exact scope is agreed for your project.
