Final Report Lot 9: Public street lighting - Amper

► Electronic ballast
The bill of materials for the ballast is entirely based on literature (Hermann C. et al, 2005). A
simplification is performed according to the most important materials/components. The other
components of the control gear are taken over from the HPM lamps.
The following table presents the input data as they are modelled in the VHK model for the
environmental assessment.

the CFL 36W lamp

The modelling of the manufacturing stage of the control gear is identical to the manufacturing
of the lamps. We assume no specific differences in the production parameters among the
different control gear. Following the VHK case study we assume that for the production of 1 kg
sheet metal, 1.25 kg sheet metal is needed as input material (25% sheet metal scrap). The
environmental impacts related to the manufacturing stage are automatically generated based on
the input data with regard to the used materials. Therefore the tables with regard to the
manufacturing stage of the control gear are not included in this report.
4.1.5 Luminaires
Every manufacturer of street lighting luminaires produces different models (e.g. historical
design, modern design, futuristic design etcetera) and in every model, there are different sizes
for different lamps. Out of this enormous number of different luminaires, CELMA provided
the BOM’s for three types, representing the most selled on the market. These three types are
closed luminaires with medium or good optics.
As demonstrated later in chapter 5, the materials of the luminaire are far less important for the
impact assessment than the electricity consumption in the use phase.
Therefore it is not useful to calculate the BOM’s for open luminaires and all other types. In the
calculation of the energy consumption in the use phase, also open luminaires and luminaires
with poor optics will be taken into account (see 4.3.1.4). These 3 defined types of luminaires
