Light as spatial behaviour
Responsive light combines physical placement with programmed behaviour. The physical layer shapes how people perceive the room; the control layer gives it rhythm, atmosphere and time.
Refractiv defines light as part of the same composition as image and sensing. Colour, intensity, transition and timing are treated as spatial behaviours within the media system.
Addressable control within the media system
Responsive light can live inside a ceiling, a wall, a mirrored volume, a custom fixture or a sequence of architectural details. Its placement shapes perception, while its behaviour gives the space a living temporal layer.
Most systems rely on addressable LED or pixel-mapped control. Depending on the project, the control layer may use DMX, Art-Net, sACN, SPI-based pixel drivers or a hybrid path that combines architectural lighting control with custom media logic.
From behaviour map to operation
Responsiveness can be driven by presence, motion, time, occupancy or show cues. Sensor input is filtered and stabilised, then translated into lighting states that read clearly in the room.
The output is a lighting behaviour map: spatial topology, scene logic, control structure and integration notes for lighting and fabrication partners. Documentation and operator training support ongoing use.
Technical signals
Inputs: presence, motion, time, occupancy, or show cues.
Behaviour: colour, intensity, transition, and timing treated as spatial behaviours, with sensor input filtered and stabilised.
Media output: addressable LED and pixel-mapped light across ceilings, walls, mirrored volumes, and custom fixtures.
Control: DMX, Art-Net, sACN, SPI-based pixel drivers, or a hybrid path with custom media logic.
Operation: lighting behaviour map, integration notes for lighting and fabrication partners, documentation, and operator training.
Where it is used
Hospitality and nightlife, retail, brand pavilions, and cultural interiors where light carries the identity of the room.
