Refurbishment in Trade, Commerce and Administration
Production plant lighting
Workplace lighting in industry and trade needs to meet the highest quality and safety standards. The right light
demonstrably helps reduce error rates and absenteeism.
Explain to your customers that good lighting
technology is a worthwhile investment:
modern solutions are considerably more
efficient than old installations and reduce
maintenance costs. Numerous studies also
show that good light and higher illuminance
can boost productivity in a company:
Older employees generally require more light.
Younger employees are also more focused
and productive.
There is a measureable downturn in error
rates.
Work-related accidents and absenteeism
decrease sharply.
[25 + 27] Good work lighting promotes motivation
and performance, guards against accidents
and saves energy and costs.
[26] Combining high luminous intensity
with a long life, LEDs are in increasingly widespread
use in production premises.
Luminaire selection
For the general lighting in a production hall
up to 6 metres high, wide- and narrowbeam
continuous rows should be installed
parallel to the main viewing direction. Supplementary
workplace luminaires need to be
tailored to the specific visual tasks performed.
Alternatively, dedicated task area
luminaires can be installed at workplaces.
For halls over 6 metres high, high-bay reflector
luminaires are the right choice.
Lighting in industry and trade often needs to
satisfy exacting requirements in terms of
electrical, thermal and mechanical reliability.
Explain the luminaire protection classes and
degrees of protection required and find out
about any fire and explosion protection regulations
that need to be observed as well as
the mechanical loads to which luminaires are
exposed. Make sure that standard-compliant
emergency and safety lighting is installed.
Glare-free lighting
As a general rule, ergonomically correct
lighting needs to be glare-free and should
have very good colour rendering properties,
especially where demanding visual tasks
need to be performed. Neutral or daylight
white light is a time-honoured solution.
Guidance on design is provided by DIN
EN 12464-1 and workplace regulations
(Arbeitsstättenrichtlinien).
LEDs in production premises
LED luminaires are in increasingly widespread
use in production premises. With a
long life and extremely efficient, they deliver
instant flicker-free uniform light and are impervious
to vibration. Further significant
savings can be achieved by harnessing
daylight, e.g. through a saw-tooth roof or
domelights. The artificial lighting is then regulated
to supplement daylight only as required.
That saves electricity costs and reduces
the need for maintenance.
