Halogen illumination system
The ceiling mount is equipped with an illumination system for fiber illumi-
nation. The lamp housing contains a backup lamp which is automatically
swung into the illumination beam path when the first lamp fails.
If required, the illumination system can be equipped with a second lamp
housing so that two separate illumination systems are available for fiber
illumination.
1 Lamp module
2 Ventilation grid
Do not cover the ventilation grid! Make sure that drapes do not cover
the grid. This can lead to overheating of the lamp modules and to lamp
failure.
3 Flap
The flap is the mechanical indicator for the operating status of the ha-
logen lamps.
– When the flap is closed, the main lamp is operative (green light (9)
is on).
– When the flap is open, the main lamp has failed. The backup lamp
is operative (yellow light (8) is on).
4 Manual selection of the backup lamp
If the automatic selector system fails, press this button to switch on the
backup lamp.
5 Opening the lamp module
When you press this button, the lamp module is slightly ejected. Pull
out the lamp module all the way for lamp change.
6 Filter selector knobs
The filter knobs have four positions:
0 no filter
1 GG 475 filter: to protect the patient's eye during surgery against
unnecessary (blue) radiation (retinal injury).
