Luminaires
By selecting the right luminaires it is possible
to achieve a considerable savings in
investment, energy and maintenance costs.
For this purpose, the following criteria can
be applied.
Luminaires with optimised reflectors
• Direct the light onto the street or road and
not to the side. The lamp‘s luminous flux is
optimally used for illuminating the surface
of the road and results in higher road luminance
or illuminance levels.
• Allow for greater intervals between poles
and thus reduce the investment, energy
and maintenance costs,
• Produce less glare,
• Eliminate light emissions that disturb
residents,
• Are especially effective for high-pressure
tubular lamps, e.g. HST.
Standard products instead of custom-made
products
• High cost-effectiveness due to inexpensive
storage of replacement parts and maintenance
and servicing plans.
89 20 decorative lighting, e.g. pillars /
good colour rendering /
luminous flux temperature-dependent
83 16 Subsidiary roads, quiet zones,
decorative lighting / good colour rendering /
luminous flux temperature-dependent
140 18 Traffic roads, accent lighting and outdoor work areas,
colour rendering low / colourful safety signage must be
illuminated additionally with lamps of better colour rendering
115 8 Quiet zones,
decorative lighting, sports facilities,
accent lighting / good colour rendering
56 16 Traffic roads and outdoor work areas, colour rendering
and luminous efficiency low, thus not suited for new installations
(see EUP Directive on Implementation, page 348).
180 12 extremely poor colour rendering,
thus only usable in special cases
(e.g. lighting of locks and tracks)
Induction lamps 80 60 Use primarily only if access to the luminaires
is difficult and thus extremely complex maintenance,
high price for lamps and control gear, good colour rendering
LED 60 60 decorative lighting,
orientation lighting,
colourful pathway lighting systems
Mains-voltage
halogen lamps
24 2 decorative lighting / good colour rendering,
extremely poor luminous intensity, usable only in special cases
• Ability to provide replacement parts over
decades.
• Select photometrically optimised and
efficient luminaires.
• Preference should be given to a timeless
design over trendy designs. Technical
quality is, however, especially important
for investment when long-term life is
expected.
• Urban architecture is not the sole decisionmaking
criterion.
• Quality products with a life expectancy of
25 years and more.
• Decision should be based on the overall
annual costs and not the investment costs.
Maintenance expenditure
• High degree of protection of the luminaire‘s
optical system decreases the ingress of
dirt and dust and thus cleaning costs.
• Depending on the outer design, external
cleaning may also be effected with the aid
of rain.
• Easy actuation of clips on luminaire covers
and connection housing of the luminaire.
• Simple replacement of lamps.
• Easy replacement of electrical components.
• Vandalism-safe construction.
• Impact-resistant luminaire covers.
• Easy installation due to plug-in connectors.
Wattage reduction in single-lamp
luminaires or half-night switching in case of
two-lamp luminaires
• Save during periods with low traffic usage.
• Uniform lighting that is essential to safety
is maintained.
• Single lamp luminaires allow for more
effective optical systems.
• Two-lamp luminaires ensure safety in case
one lamp fails and are especially suitable
for half-night lighting.
