PERFORMANCE iN LIGHTING designs and produces unique street optics to match the
latest legislative and regulatory developments. The primary objective of these optics is
to use the light only where needed. These optics, based on field experience, are based
on the central feature that differentiates all the projects: the ratio between luminaire
installation height (H) and the distance between the centre of gravity of the same
and the limit of the roadway (L). The name of the different street optics (SR), therefore
expresses this ratio (L/H).
LIGHT ONLY WHERE NEEDED
Cycle and pedestrian pathways
This type of path, often not adjacent to
a road, requires dedicated lighting. The
width is between 1.5 and 3 meters, and
the height of the supports is between 3
and 4 meters. In this type of high plant
ratios between distance and height of
the piles are required. Given the low L/H
ratio, the SR/075 optics are the most
suitable. They are designed to guarantee,
in pedestrian and cycle applications,
relationships between distance and
height up to seven with consequent cost
reduction.
New installations
The choice for the appropriate optics
for improving the efficiency of an old
plant is limited by the existing supports
that are generally maintained. They are
constrained to the height and distance.
On the other hand, in new installations,
it is possible to optimise the system
parameters containing the number of
light points. In these cases, the most
indicated optics is the SR/100. Given that
in such systems it is good practice to
choose the height of the poles to obtain
an L/H ratio of about 1 and because it
allows reaching an inter-distance up to 4.5
times the height of the supports.
SR/075
L/H = 0.75 (0.5 ≤ L/H ≤ 0.875)
SR/100
L/H = 1.00 (0.875 ≤ L/H ≤ 1.125)
