6. Functions
The DALI MSensor has the following functions and user interfaces:
6.1. Constant light control
6.1.1. Description
Constant light control makes it possible to match the lighting in a room to the naturally available ambient light. To do
this, the ambient light sensor monitors the illuminance in the room, compares it to the previously set brightness
setpoint and dims the light until the received illuminance matches the desired setpoint. If several DALI MSensors
are used in the same luminaire group, the light is dimmed until the light value is no longer less than the setpoint at
every sensor.
Where ambient light values are high, this can result in ambient light-based bright-out and bright-in. If the measured
illuminance exceeds a specified threshold value for a period of time that is longer than the specified delay time, the
luminaire group is switched off by the DALI MSensor. This also applies in cases where motion is detected in the
room. The luminaire group is switched on again as soon as the measured illuminance falls below the brightness
setpoint.
The Constant light control function ensures that the illuminance in the room remains constant and changes due to
variable amounts of ambient light in the room are compensated for. This produces greater comfort, illumination is
always properly adjusted, and it also saves energy.
Detection area of the ambient light sensor
The detection area of the sensor is sized so that a relatively large area, rather than just an individual location on the
task area, is covered and assessed. This ensures that objects being moved around cannot cause incorrect
measurements.
