13.2.1 Constant light management, light target value and light measurement
Constant light management uses the light target value to determine wheth-
er, for example, the light power increases in daylight and if a presence is
detected, as the daylight is lower than the light target value. It can also
determine whether the light switches off because daylight exceeds the light
target value. By default, the light target value is set to 500 lux per channel.
This can be changed in the two submenus Configuring via light sensors and
Manual settings.
Apart from the light target value, constant light management also requires
the current light value in order to compare both values. The way in which
the Light Control Boxes receive the current light value depends on the con-
nected devices:
•
Connected lights without a light sensor:
The light value is transmitted to
the Light Control Box from the connected DALI detector.
•
Lights with an integrated light sensor
report the light value to the Light
Control Box that performs constant lighting control. The light sensor
can be calibrated.
If a channel does not have a sensor because only one light with-
out a light sensor is working on the channel, the value of the DALI
presence detector is used for this channel.
Light target values always apply to one channel. However, constant light
management can control different lights on one channel in different ways
if these lights have light sensors. If a channel only has lights without light
sensors, all lights are regulated to the same brightness value.
