Dimming
Installation example Open-plan oce with e-Sense ActiLume
General lighting in the open-plan oce can be made more eective
if the installation is planned in advance and adapted to the daily
activities, reacting to both occupancy and the level of incidental
light in the space. Luminaires placed away from the windows are
controlled with a 30 % oset. Low light level with absenteeism, but
not switched o. This is eective control in an open-plan oce.
Advantages:
Automatic switching on.•
Automatic adjustment to 20 % after 15 minutes.•
Oset 30 % for luminaires placed further in the room.•
Manual control if necessary.•
Daylight control.•
Occupancy detectors linked for a larger area.•
Easy programming with IR-transmitter.•
Proposal for the installation of control in a large oce
General lighting for the open-plan oce can easily be made more
eective. Grouping the luminaires into zones based on location and
window position, ensures you can get the right amount of light
when working, and at the same time a solution that is in harmony
with today’s approach to energy. Daylight control becomes more ef-
fective and easier to manage if the detection and adjustment areas
are not too dierent in size. Using an e-Sense ActiLume master lumi-
naire placed in the window row and connected luminaires assigned
to channel 1 (window row) and channel 2 (inner placement in the
room) the depreciation of daylight in the room is compensated by a
30 % oset for the inner luminaires.
This gives an adjustable, but even light over the entire area. For
example, if the window row is adjusted to 40 %, the inner rows are
dimmed to 70 %, i.e. a 30 % oset. This function has previously been
sought, but was practical impossible to achieve without an advanced
bus system. Today it is pre-set with a master sensor placed in a
luminaire.
The lighting zone can cover about 8 workplaces (depending on the
furnishing) and 11 luminaires. Occupancy detection within the zone
is expanded by extra occupancy detectors connected to the same
control signal as the luminaires. Functions over and above the stand-
ard options can be programmed with IR-transmitter 86155.

Installation in an open-plan oce with
e-Sense ActiLume. The zone that one
ActiLume system controls covers max.
11 luminaires, in this example eight
luminaires. If the oce is larger, parallel
systems are installed that are adjusted
individually. The dierent control func-
tions are connected to the master
luminaire, which is placed in the row by
the window. Automatic switching on
with occupancy. After the last detection
the lighting is adjusted down to 20 %.
After two hours the lighting is switched
o completely. This setting can easily be
changed with an IR-transmitter (86155)
for programming.
Luminaires in the row by the corridor,
furthest from the incidental daylight,
are controlled via the DALI 2 line, which
has an oset of 30 % from DALI 1. This
means that the luminaries furthest in
the room give more light in the dimmed
state. The size of the oce room usually
demands occupancy detection to be
supplemented with one or more extra
sensors, which are placed centrally in
the ceiling (86152).
