4.4 Automatic Light
For more security and greater convenience, LB Management offers components for automatic,
movement dependent lighting control. If movement is detected in the detection area, our auto-
matic switches, observers and presence detectors switch on the lighting automatically and off
again after expiry of a specified delay time – convenient and energy-saving.
The movement-dependent lighting control can basically be divided into two typical application
areas:
Automatic switches and observers are movement detectors that are particularly suitable for
passage zones such as stairs or corridors. The tasks of the observer are to switch on the light
depending on the ambient brightness if any person enters the detection range and to switch
off the light when the room is left again. The main focus here is the prevention of dangerous
situations in the dark. In this application, it is not required to be able to switch off the light again
manually. The desired delay time always expires here and the light switches off if the delay time
is not restarted by movement again.
Presence detectors are movement detectors that are typically placed in rooms where people
are present longer. The presence detector primarily has the objective to save energy and to
switch off or dim the room lighting when no person is present. The presence detector must also
be able to recognise small and sporadic movements for this. In this application, the light must
also be able to be switched off manually. Presence detectors can be switched off as required
and then ignore movements in the detection range.
All LB Management automatic switches and ceiling observers / presence detectors also measure
the ambient brightness and thus make the control of automatic lighting even more intelligent:
You can set that the lighting is only switched on for movement if a specified brightness threshold
is undercut. Or you design more complex installations, in which the tripping of a movement de-
tector switches other automatic switches or ceiling observers / presence detectors independently
of the brightness.
JUNG ceiling observers / presence detectors can be used as observers and as presence detectors.
