4.6.2 Lighting intensity
Lighting intensity concerns brightness and is measured in lux.
Lighting intensity can be adjusted within a range of 30% to 100%.
In addition, Endo lighting intensity can be selected. The Endo
lighting intensity is a fixed-setting lighting intensity (< 10%)
primarily intended for endoscopic surgery.
4.6.3 ALC Plus (Adaptive Light Control Plus) - automatic measurement of the working distance
The ALC Plus function allows lighting intensity to be automatically
adjusted when the position of the lamp head relative to the wound
area changes. ALC Plus facilitates optimal focusing of the light
onto the wound surface and thus ensures optimal illumination of
the wound area.
If the lamp head is repositioned during surgery, the distance
between the lamp head and the wound area is automatically
determined and the light field and lighting intensity are adapted/
optimized accordingly.
Notice: The function is only triggered when the working distance
to the wound field of the patient is changed by moving the surgical
light. Changing the patient’s position does not trigger automatic
measuring and optimization of the lighting conditions.
For the automatic function, the working distance between the
surgical light and wound area of the patient must be between
80 cm and 130 cm (31.50 inch and 51.18 inch).
4.6.4 Color temperature
The user can make contrasts as visible as possible by changing the
color temperature. At the same time, a higher color temperature
allows low-fatigue working and supports the ability to
concentrate, for example during operations carried out at night.
Four color temperatures are available: 3500 K – 4000 K – 4500 K
and 5000 K.
4.6.5 Shadow management
The sensor-controlled assistance system of the surgical light
ensures consistent lighting conditions without disruptive shadows,
even if the surgeon is working directly under the surgical light. The
assistance system detects obstacles between the surgical light
and the patient's wound area. Corresponding LED modules of the
surgical light system are activated and deactivated by the
assistance system. Even without any manually adjusted settings,
the wound area is always illuminated as effectively as possible.
Where there are 3 surgical lights within a light system, shadow
management can only be activated in 2 surgical lights.
4.6.6 Synchronization
The Synchronization function is used to balance the functions of
all surgical lights within a single lighting system. When this function
is activated, the current settings of the selected surgical light are
automatically transferred to all other surgical lights in the lighting
system. The following functions can be synchronously adjusted:
