Support and care
around the clock
The hospital's 24-hour nurses’ station is the contact point for patients around the clock. This
is where medication is stored and dispensed, and office work performed. The lighting at the
24-hour nurses’ station must reconcile partly suboptimal spatial conditions with long shifts
and high traffic. Boosting its central accessibility, the round-the-clock station is often located
deep inside the building. This results in minimal natural daylight. Since employees work here
for long periods, the artificial lighting must provide a healthy supply of light similar to daylight.
Generously dimensioned indirect lighting with dynamic light colour curves helps with daytime
orientation.
EN 12464-1 stipulates that ceiling illuminance should be just 30 lux. Paired with square LED
panels, the high luminance contrast creates an almost oppressive spatial impression. In com-
parison, round or ring-shaped luminaires with a large indirect light component and an illumi-
nance of between 500 and 1000 lux create an open, friendly impression. This both creates a
more comfortable environment for staff and patients, and the 24-hour station suggests a sense
of security – essential factors in stressful or tense situations.
In some areas of activity, higher illuminance may be appropriate in places. For example, doctors
and carers can read the package inserts for medicine or information on medical utensils better
and provide information more quickly. The lighting should be glare-free and reflection-free at
the computer workstations in the 24-hour nurses’ station. To eliminate reflected glare, lumi-
naires are not positioned above the field of vision but to the left and right of the workstation.
The degree of direct glare is described by the UGR value, which is a maximum of 19 in the office
area. This is where the use of high-quality office luminaires pays off. They ensure pleasant and
healthy working conditions at a particularly challenging hub in the hospital.
