Flexible light for
mental agility
Lecture halls are central to education and discourse. Successful lighting creates optimal con-
ditions for teaching and presentations by providing good visibility, focussing attention on the
plenary and supporting various teaching formats.
New, teaching methods at universities and technical colleges that use technology place addi-
tional demands on lighting design. Architecturally, many lecture halls are designed so that they
can be completely darkened for projector presentations. As a result, artificial lighting must per-
form all the more. Dynamic lighting control and pre-programmed light scenes are indispensable
to create the best working lighting for variable teaching methods.
Sufficient light intensity (300 – 500 lux) is important around the lectern so that lecturers
can be easily seen from any seat. If the blackboard is used, it should be illuminated with the
lowest possible reflection. The lighting requirements in such cases is 500 – 750 lux lux with
an increased uniformity of ≥ 0.7. The right lighting solution creates conditions where students
can take notes without glaring. This is achieved, for example, by profile luminaires arranged in
parallel above the rows of chairs. In addition to homogeneous basic lighting and very good glare
control, they ensure a structured and modern appearance.
Last but not least, safety in lecture halls plays a role. Entrances and exits, stairs and steps must
be lit separately so that students can safely enter and leave even a darkened lecture hall. A
forward-looking lighting concept takes into account the numerous scenarios and remains agile
– like a curious mind.
Lighting requirements (EN 12464-1)
• lecture hall: light intensity of at least
500 – 750 lx, uniformity of 0.6 /
glare reduction of UGR ≤ 19
• light in the podium area: light intensity of at
least 300 – 500 lx, uniformity of 0.7
• blackboard: light intensity of at least 500 lx,
uniformity of 0.7
• ideally individually controllable lighting
(room light / board light / lectern)
• orientation lighting during lectures (entrances
and exits, stairs and steps)
