2015 is the International Year of Lighting and Bres-
cia, a city in northern Italian, has undertaken an
energy savings project, replacing all the traditional
lamps in public lighting with LEDs. The project
should be completed within 2016.
In what is a standout success for AEC, ITALO
luminaires have become a benchmark in public
lighting and over 16 000 Italo luminaires have
been specified for Brescia, which will turn into a
Smart City.
AEC is well known for its technical proficiency,
and the company’s extraordinary production set-
up has contributed to this latest success since
completely automated assembly lines guarantee
quick response times.
Brescia covers an area of 90.34 km2 and has
about 195 500 inhabitants. At present, the city
consumes more than 18 million kWh of electrical
energy each year. With new LED lights, the city
forecasts a 40% reduction in annual energy con-
sumption, leading to savings of around € 8 million
for municipality coffers in just 10 years.
Opto Semiconductors has added the Soleriq L 38
filament LED to its product range. The long thin
shape of the LEDs provides the basis for filament
lamps which, in terms of their appearance and
emissions characteristics, aremore than a match for
their incandescent lamp predecessors. Soleriq LEDs
offer uniform colour appearance and a quality of
light that is ideal for aesthetic lighting applications.
Each Soleriq L 38 has a length of 30 mm and
a diameter of 1.8 mm. This shape, which is similar
to that of a conventional filament, plus an emis-
sion angle of 360° and an excellent quality of light,
makes it perfect for use in LED lamps
of all wattages that mimic the appear-
ance of classic light bulbs. Soleriq L 38
LEDs are offered in different MacAd-
am* groups according to their colour,
forward voltage and brightness – at a
temperature of 85°C, which closely
Filament LEDs from Osram
LED lighting means greater efficiency and
savings. In addition, LED lamps have a
longer life cycle leading to fewer damaged
lamps and less maintenance. The city has
calculated that every year fewer than 2500 lamps
will get burnt and less than 10 000 will be replaced.
Energy efficiency, longer life cycles and reduced
maintenance costs impact on the environment. A
40% decrease of consumed energy every year
leads to a reduction of carbon emissions. LED lon-
ger life will also avoid the production of more than
1.5 tons of RAEE (electric and electronic waste)
every year. The replacement of the old lamps will
remove any mercury trace and other polluting
substances according to reference standards.
Last but not least, ITALO’s state-of-the-art optics
will guarantee a better lighting for citizens’ safety.

“Customers will benefit from these properties,
particularly if they want to install multiple lamps or
luminaires fitted with Soleriq L 38 in a room”, says
product manager Wong Kum Yih of Osram Opto
Semiconductors. “Incorporating the LEDs in classic
lamp production lines is simple because, with only
minor modifications to the manufacturing process,
they can be installed in the lamp in the same way
as traditional filaments.” Sorting by forward voltage
enables multiple LED filaments to be connected
in parallel, resulting in reliable operation with no
overloading of individual filaments.
The Soleriq L 38 offers high brightness. It is
available in three versions with 90, 130 or 140 lu-
men (lm). These values enable all previous lamp
wattages up to 60W to be replaced with equivalent
LED filament solutions. The driver voltage needed
for the LED filament lamps can also be adjusted.
All versions have an extremely high luminous ef-
ficacy of 150 lm/W and provide warm white light
(2500 to 4000 Kelvin). Thanks to the good colour
rendering index of over 80, the Soleriq is ideal for
indoor lighting.
