Compact LED street light,
with an aerodynamic shape with reduced surface
exposed to wind. Casing self-cleans with wind and rain.
Upper section and rotor in die-cast aluminium, surface finish in oven-baked
polymer powders. Highly resistant to corrosion, abrasion and flaking. Long-term
colour stability and excellent UV resistance. Lower section of casing in ASA
plastic – highly-resistant to atmospheric agents and exposure to direct sunlight.
Thermal dissipation is by natural convection (i.e. without fans) across the numerous
fins on the upper part of the casing, which are designed on the basis of
the strictest thermal stress tests. This temperature controlled structure ensures
the maximum efficiency of the LEDs and the power supply, and thus long
service life.
The IP66 protection rating of all electrical and electronic parts is guaranteed by a
sealing gasket in two component polyurethane applied by a robot device directly
to the casing using FIPFG (formed-in-place foam gasket) technology, which is
also used in the automobile industry.
All exposed screws and bolts are in stainless steel and thus will not corrode
even in extreme conditions (salty air etc.).
LED The LED circuit board,
is in aluminium which has an extremely low thermal
resistance and can drive from 48 to 96 LEDs for powers up to 205W and luminou flux up to 21.400lm.
Only the highest-quality LEDs of the best worldwide
producers, with output ratings of ≥150 lm/W (as laid down by CEI standard EN
62471 governing the photobiological safety of lamps and lighting systems in general).
Colour temperature 4,000 K; colour rendering index (CRI): ≥70; luminous
efficacy 90 – 106 lm/W.
Available on request: LEDs with colour temperatures from 3,000 K to 5,000 K.
Panel in toughened non-reflective glass
The glass, thickness 4 mm,
protects the secondary lenses from the exhaust gases produced by motor
vehicles. Impact resistance IK08. Mechanical attachment of the glass without
use of glue or sylicon in order to allow an easy separation of the materials at
the end of the life-cycle.
Optics
High-efficiency secondary lenses in PMMA (anti-yellowing) with a
variable photometric curve depending on the application. Secondary optics are
attached by micro-screws without use of glue.
The internal plastic profiles serve as a lateral cut-off designed to limit the glaring
effect from a distance. A special anticondensation valve provides efficient
exchange of the air, which is essential to prevent the formation of condensation
on the glass panel, without affecting the waterproofing of the unit.
Electronics
The high-efficiency power supply modules feature built-in protection
against power surges and resin-based protection from the vibrations
generated by motor vehicles and wind.
If the unit is switched on while the ambient
conditions are outside its operating limits, the electronic control system
reduces the luminous flux until the temperature returns to within safe operating
limits. The internal power supply operates with constant DC current via a
high-efficiency electronic driver. Depending on the desired efficiency/consumption
ratio, the appliance is available with power supply settings from 350 mA to
700 mA.
