4.6 LED Lighting
The equipment can be equipped with a LED lighting option. This
illuminates the surface of the table at an adjustable light intensity.
For example, the LED lighting option can be used to cultivate pho-
totrophic cells.
4.6.1 Setup and Function
The LED lighting is affixed to the ceiling inside the chamber. It can
generate a light intensity of up to 200 µmol m
-2
s
-1
(at the 100 %
setting), which is distributed evenly over the surface of the table.
The LEDs are protected from being hit by a protective cover made
of acrylic glass. The acrylic protective cover has a large opening in
the middle to allow air circulation. The protective cover
height of the incubation chamber by approx. 30 mm.
To ensure better light distribution in the incubation chamber, the
glass sheet is covered with darkening foil when using LED lighting.
4.6.2 Operating the LED Lighting
The LED lighting unit is operated using the Light parameter. The
bottom of the alphanumeric display shows the value in % with the
symbol Light.
The light intensity can be regulated from 1 to 100°%. It responds
linearly to a value of 5 to 200 µmol m

.
For a detailed description of how to set and activate the parame-
ters, see chapter 7.4 "Adjusting, Activating and Deactivating Pa-
rameters", page 81.
Restriction
The LED lighting radiates heat when in operation. Hence, the LED
lighting can only be operated together with a cooling unit (internal
or external cooling system). If the equipment is operated with inter-
nal cooling, the temperature is regulated fully automatically. If the
equipment is connected to an external cooling system, you must
ensure that the cooling is fully functional when operating the LED
lighting.
