Street and Advertising Lighting and Signalling
| Photovoltaic technology
has been widely used for street lighting for years. Even though
the main roads are connected to the public electric grid, it
is often expensive and difficult to have access to it to supply,
for example, only one light signal. |
This is why the traditional passive
signs are often used, characterised by phosphorescent
paints or composed by simple reflecting systems. The
so called “passive” signs are surely effective,
but if it is foggy or if the visibility is bad? Studies
carried out by the R&D Department of ENERECO srl
showed that, in some situations, the substitution of
the passive street signalling (stop and danger signals,
give-way signs ext.) with proper traffic lights supplied
by photovoltaic energy reduced of 25% the accidents
and improved the traffic flowing. Using the photovoltaic
street lighting systems, this value reaches 30%. In
fact, thanks to the technology developed by ENERECO
srl it is possible to design and realise photovoltaic
street lamps or lighting systems for street posters,
using not only the traditional low pressure sodium
lamps of 18, 26 and 36 W but also high pressure sodium
lamps, halide vapours lamps till 70W and fluorescent
lamps till 80W.
...Every year 9000 people die on the Italian roads;
300.000 are the wounded, and more than 20.000 are the
serious disabled of this not declared war. Italy is
the only country among the richest European ones where
the number of died and wounded people increases rather
than decreases. The European Parliament has asked Italy
to reduce of 40% in ten years these numbers... (Extracted

The programme of ENERECO srl
ENERECO srl has developed a series of photovoltaic and hybrid kits and devices
for the street and motorway use such as:
“LPS KIT” PHOTOVOLTAIC STREET
LAMP
The photovoltaic or the photovoltaic
and hybrid street lamp can be installed in any situation provided
that there are the proper insulation or wind characteristics.
The easiness of installation and maintenance makes it a strategic
product for the technical departments of the municipalities,
which can grant their citizens a lighting service also in isolated
sites or in those places difficult to be reached by the traditional
lighting systems (mountain, rural and coast sites).
LIGHTING FOR STREET AND ADVERTISING POSTERS
The same KITS used for the photovoltaic
street lamps can be employed also for the lighting of street
and advertising posters (messages, direction signs, ext.),
thanks to the use of the innovative ballasts for white light
lamps such as the compact fluorescent or the halide vapours
lamps.
PHOTOVOLTAIC KITS WITH LED TRAFFIC SIGNS
These kits are inserted in the traditional
traffic signs, on crossroads, dangerous bends, guardrails,
ext.. Sequential light systems are part of this group too.
LED SEMAPHORIC AND PRESEMAPHORIC PHOTOVOLTAIC KITS
The use of particular led matrix allows
to substitute the old filament lamps of the traffic lights,
granting less electrical consumptions, more reliability of
the signalling (it is impossible that all leds composing the
matrix burn out) and longer life of functioning (less maintenance).
Moreover, the leds are suitable to the supply through photovoltaic
or hybrid systems.
