Corridors and staircases are the main circulation routes in a hospital. Patients, visitors, and staff
should be able to navigate quickly and safely. They also make a significant contribution to the
first impression people form of the hospital. Bright, professional lighting is crucial for this. Du-
ring the day, illuminance levels of at least 100 lux (according to EN 12464-1) must be achieved.
When planning ceiling lighting, it is important to bear in mind that patients are often transported
while lying down. A high indirect component prevents glare by reducing the contrast between
the ceiling and the light emission surface. Vertical illumination, or brightening of the walls, is
another option as it visually enlarges the room. In high-ceilinged rooms, large suspended lumi-
naires with direct/indirect light components are a good choice for pleasant illumination.
The biological standard specifications for lighting are set out in DIN/TS 67600. During the
day, a melanopic and day-equivalent illuminance of ≥ 250 MEDI lux is recommended. This
corresponds to about 370 lux at head position for a 32-year-old standard observer. For older
persons, significantly higher cylindrical illuminance levels are necessary for a biological effect.
To correspond to the natural hormone release of the human organism, light colours up to
5300 K are well suited in the morning, while very warm white colour temperatures of ≤ 2700 K
should predominate at night. Age-specific correction factors for 50-, 75-, and 90-year-olds can
be found in DIN T/S 5031-100. Since corridors and staircases in the hospital are used around
the clock, they are also illuminated at night. To save energy, the light intensity may be dimmed
down to 50 lux at night. An automatic light control system dynamically adjusts the brightness
to the time of day. Special sensor-controlled luminaires can be easily programmed and create
dynamic, natural lighting conditions that also reduce energy consumption. XAL’s MASTER UNIT
boasts a control system to easily realise Tunable White gradients.
Requirements
• Corridors: 200 lux during the day, operating theatre
wing corridors 300 lux, 50 lux at night
• Automatic adjustment of light intensity for energy
efficiency
• Planning recommendations for biologically effective
lighting (DIN/TS 67600)
• During the day 250 MEDI lux, for example, at 5700 K, at
night 50 lux at 2700 K
