Lighting special: Energy efficiency and ErP
Looking to the future and energy efficiency are topics that are influencing local authorities these days. For this
reason, lighting concepts are called for that are based on innovative light sources and efficient luminaires, integrated
into intelligent control systems.
Towns and communities make a significant
contribution to climate protection as
energy efficiency has become a central
aspect with city marketing with light. Authorities'
lighting concepts are increasingly
measured according to how they address
the potential for the reduction of energy
consumption. This isn't just a question of
reducing the level of the lighting or abdication
of light quality. Much more it is to do
with harmonising the needs of the people
in terms of visual comfort and safety with
ecological and economic demands. Innovative
lighting solutions in combination with
intelligent control systems are the answer
to this delicate balancing act.
Wide-ranging benefits result from such
lighting concepts:
▪ Shaping the profile of the communities
through attractive light designs
▪ Improved light quality for the good of the
citizens and for increased safety
▪ An image-plus through commitment to
sustainable energy-efficient products
▪ Reducing the load on the environment
through significantly reduced energy consumption
and reduction of CO 2
emissions
EU regulation 245/2009 will have a large
effect in this area and clear the way for
energy efficiency.
Energy-saving potential - road lighting
Communities can reduce their energy
consumption by up to 70% by deploying
new road lighting equipment. These possible
savings result from an improvement
in the lamps, operating devices and
luminaires. LED lights can even make
savings of up to 80% possible. However,
the suitable photometric equivalent is
not yet available for each application.
But, through the progress that is being
made in LED technology, further application
areas will soon be catered for.

Such energy saving measures are not
just brought about because of a desire to
protect the climate or because of statutory
guidelines. Also spiralling energy prices
and reduced budgetary resources are
forcing towns and communities to act.
Energy consumption can be reduced by
up to 80% with new lighting technologies
while at the same time delivering significantly
increased light quality. Thus, the
eco-design guidelines also have relevance
for lighting in the public domain, as in the
last years, road lighting has developed
to become a design element in the urban
space. This has increased the number
of lighting points and the energy requirements.
In addition, existing equipment is
based on outdated, inefficient technology
both in terms of the deployed operating
devices and the lamps themselves. The

Statutory requirements
Almost 20% of global power consumption
is used for lighting. And as a result, introducing
energy-efficiency into the lighting
market has become a high priority for the
European Union. The principal instrument
of EU legislation in this area is the EU
framework directive 2009/125/EU (ErP),
introduced on 20th November 2009,
which, as the successor to the original
eco-design Guideline 2005/32/EGU(EuP),
focuses on the eco-design of "energy
consumption relevant" products. The
minimum requirements for non-directional
