Final Report Lot 9: Public street lighting - Amper

experience from a team member as former responsible for over 750,000 street lighting points)
were compaired with catalogue prices. Taking into account that most custumers are smaller, a
weighed average was proposed in an expert meeting with European sector organisations. The
sector experts agreed with this proposal.
The LMF values in the tables are chosen in accordance with technical report CIE 154 and are
related to the ingress (IP-rating) and 'defined pollution categories'.
For road categories F (fast traffic) and M (mixed traffic) in this study the 'medium pollution'
category is used, defined as: “Moderate smoke or dust generating activities nearby - Moderate
to heavy traffic - The ambient particulate level is no more than 600 micrograms per cubic
metre”.
For road category S (slow traffic) the 'low pollution' category is used, defined as: “No nearby
smoke or dust generating activities and a low ambient contaminant level - Light traffic -
Generally limited to residential or rural areas - The ambient particulate level is no more than
150 micrograms per cubic metre”.
The LLMF values in the tables are chosen in accordance with technical report CIE 154 (2003),
adapted to the new values presented by ELC.
The factor UF results from photometric calculations.
For this calculations, road geometry and pole distances were taken in accordance with typical
values in chapter 3.
The average illuminance Eavg [lx] on the road was calculated for different luminaires.
For the illuminated area one section between poles, A [m²] = road width [m] x pole distance [m]
was taken and accordingly the luminous flux emitted by one lamp [lm].
Because:
Eavg [lx] = Useful luminous flux [lm] / A [m²]
we can calculate the useful luminous flux.
So UF can be calculated as:
UF = Useful luminous flux / Luminous flux emitted by the lamp.
Putting into service was taken into account for some luminaires where optics can be regulated
(e.g. by changing the position of the lamp in the reflector or by changing inclination angle);
those luminaires are identified in OM, CM or CH as stated below. Some softwares can calculate
the most energy-economical position and consequently this position was applied. For some
luminaires in OM and CM (partly) and for all luminaires in GO, GH, DR and OP, no regulation
is possible and the standard position was applied.
For the analysis of the performance parameters in this study, the following luminaire types are
considered:
• Globes with omni-directional diffuser (GO) (only in category S)
• Globes or street lanterns with hemispherical diffuser (GH) (only in category S)
• Decorative luminaire with reflector and no diffuser (DR) (only in category S)
• Open luminaire with poor reflector (OP) (only in category S and M)
• Open luminaire with medium reflector (OM)
• Closed luminaire with medium reflector (CM)
• Closed luminaire with advanced optic reflector (CH)
