LED — dimming
Dimming can deliver energy savings of up to 85%.
By installing the lighting control systems needed for daylight- and occupancy-dependent operation, the efficiency of a lighting installation can be increased significantly without any loss of visual comfort.
Combining daylight- and occupancy-dependent control can deliver energy savings of up to 85% compared with conventional systems.
This means that artificial light is provided only in those zones where it is genuinely needed.
The sensor technology is built into special “master luminaires”, which considerably reduces the installation work required.
DALI control
The light sensors of DALI dimming register the strength of the incoming daylight and regulate the luminous flux of the artificial lighting to compensate. In this example, a lower luminous flux of 40% is sufficient next to the windows. On the right-hand side of the room, opposite the windows, the flux can still be reduced to 80% while maintaining the illuminance level required by the regulations. This makes an enormous difference to energy consumption.
Automatic brightening / dimming / switch-off
The DALI lighting control system reduces the luminous flux of the artificial lighting in line with the daylight available at any given moment. The more daylight there is, the less artificial light is used. Using a motion sensor module, the system detects whether anyone is in the room. If the room is not in use, the lighting system switches itself off automatically.
