Operation
Maximum total irradiance for
combinations of lights
When using 2 or more lights to illuminate the
operating field, the permissible standard total
irradiance limit may be exceeded if the light fields
from several lights overlap. This can lead to
increased drying out of the wound site. The
thermal radiation from each light increases linearly
with increasing illuminance. A single light cannot
exceed the permissible total irradiance limit, but it
is possible when a combination of lights is used. To
avoid increased thermal radiation, observe the
following recommendations:
– Set the lights to the minimum illuminance
required for appropriate illumination of the
operating field. If a high level of illuminance is
temporarily required, it should be reduced
again as quickly as possible.
– If the maximum level of illuminance from one
light is required, the illuminance from the other
lights must be reduced. The light fields from the
individual lights should not overlap if possible.
WARNING
Risk of patient injury
If the light fields from several lights overlap,
the heat input to the wound site may be
unacceptably high. This can lead to drying
out of the wound site.
If necessary, the total irradiance must be
adjusted by reducing the illuminance of
individual lights, see "Setting the
illuminance" on page 42.
