The technology of the lighting system
3.1
The light head
The light head has a wide range of new functions that allow for ergonomic control
using the control panel on the light head or using the optional wall-mounted control
panel.
Operating modes of the non-sterile
handles (optional)
The light heads are fitted with illuminated, non-sterile handles (outer handles). The
following operating modes are available:
• Permanent illumination (factory setting),
• No illumination,
• Illumination when the light head is switched on,
• Illumination only when the light head is in stand-by mode
• Illumination in stand-by mode or when the ENDO-dimming of the light head is
switched on.
The operating mode selected by the user can be configured by a service technician
during assembly.
ENDO-dimming
ENDO-dimming is intended for endoscopic surgical procedures. ENDO-dimming
switches the light head to less than 10 percent of the light intensity.
Light intensity
The light intensity can be set in the range from 40% to 100%. A reduction (dimming)
of the light intensity does not change the colour temperature of the light.
The light intensity can be separately set for each light head.
Adaptive Light Control (ALC)
(optional)
The newly developed Adaptive Light Control allows the light settings to be adapted to
the new working distance when the position of the light head to the wound field is
changed.
The three settings for a working distance of approximately 0.8 metres, 1.0 meter and
1.2 meters are selected on the control panel or the optional wall-mounted control
panel.
The light head then automatically selects the optimum light setting for this working
distance.
Adaptive Light Control plus (ALC plus)
(optional)
Adaptive Light Control plus (ALC plus) enables the targeted electronic control of
various LEDs in order to achieve optimum illumination of the wound area. The
Adaptive Light Control plus automatically ensures even light intensity and higher light
output for the first time. The distance between the light head and the wound area is
automatically determined based on movement detection when the light head is
moved during surgery. This allows accurate adaptation of the illumination at any
time.
Sterile Light Control (SLC) (optional)
Simple swiping with a finger allows the light functions to be activated in a completely
sterile way using the sterile handle.
Adjustable Color Temperature (optional)
The function Adjustable Color Temperature is used to increase the colour contrast in
the wound area and provides a better perception of colour differences by the
operating team.
TruVidia camera system
(optional)
With the optional TruVidia camera system, a camera installed in the middle of the
light head can be controlled using an optional control device. The two camera light
heads TruLight 5310 and TruLight 5510 are fitted as standard with the ALC plus
function, as soon as the camera module is fitted.
Please refer to the overview of light versions in the Technical Data chapter for
detailed information on the availability of this option.
