Refurbishment in Trade, Commerce and Administration
Enclosed parking facility lighting
The vehicle entrances and exits of underground and indoor parking facilities are accident black spots.
Good lighting guarantees smooth traffic flows and heightens safety.
IRoad safety is the main priority in indoor
and underground parking facilities, because
they are used simultaneously by
moving and parking car drivers, motorcyclists
and pedestrians. Good lighting without
dark zones lowers the risk of accidents,
facilitates orientation and makes
vehicles, persons and obstacles easier
to recognise.
For indoor car parks, DIN EN 12464-1
stipulates a minimum of 300 lux illuminance
at vehicle entrances and exits during the
day. If the barrier is not in the same zone,
[39] Vehicle entrances and exits need to be
illuminated to at least 75 lux at night.
[40] Uniform lighting with comfortable illuminance
makes for greater safety in enclosed
parking facilities.
it should be separately illuminated to facilitate
use of the key card reader. At night, at
least 75 lux is required throughout the parking
area. However, more light is useful –
and makes for greater safety for pedestrians
and motorists. At the same time, good
lighting is an effective safeguard against
criminal assault. Luminaires are installed on
the left and right of access ramps and
should provide uniform lighting. Appropriate
enclosures and precise alignment prevent
motorists being dazzled; a high degree
of protection prevents damage due to
moisture and dirt.
LEDs and lighting management
The lighting in enclosed parking facilities
is often in operation 24 hours a day. So
operators are interested in minimising the
operating costs. Explain to your customer
how those costs can be saved:
LED light sources are an optimal option.
They are very energy-efficient, easily
controllable and insensitive to cold. And
they have a very long life, which cuts
maintenance costs. The emergency
lighting required in enclosed parking
facilities can also be easily integrated in
LED systems.
Electronic lighting management makes
for considerable savings and additional
comfort. It includes presence detectors,
for example, which activate lighting
and automatically raise the brightness
when vehicles or persons approach.
If the parking facility is also served by
daylight, intelligent control adjusts the
artificial lighting as required.
Where operating times are long and electricity
prices are rising, the capital costs
of a refurbishment measure are quickly
recouped. The longer lights are on, the
faster an efficient installation pays for itself.
