Regulation of overhead lights
Full coverage possible
In rooms where overhead lights are arranged at regular
intervals (e.g. sheds with double-ridged roof), daylight
regulation of all luminaries is generally a good solution.
The sensor can be fitted anywhere.

Here, too, areas which are in shadow should remain
unregulated, and the sensor should be installed above a
surface (work plane) offering the most constant and
representative reflection properties.The LRL 8101/20 can
be used for room heights up to 8m.
Multiple regulation zones in a single
room
Safety distance prevents interference between the zones
A large room or hall is best divided into several
regulation zones.The subdivision can be based on the
division of the room itself, otherwise 100m

- 200 m

per
zone is a useful value.
The regulation zones must not be allowed to influence
each other. Light sensors should therefore be positioned
in the centre of their respective regulation zone
wherever possible.The distance to the nearest luminaire
in the adjacent regulation zone should not be less than
the installation height of the sensors.
