The patented LED optical system:
- provides highest optical performance
- directs the LED light to where it is needed
- allows a 90% reduction of LED forward current, maintaining all optical requirements during the whole life cycle of the variable message sign, therefore increased availability and lowest energy consumption
all LEDs are continuously monitored, even when they are off; LED status will be reported to the traffic center or to a local control
conformity to EN 12966: more than 100 class-combinations of different color, luminosity, contrast, beam width, pixel pitch, LEDs, forward current, etc. have been tested and certified by SGS/INTRON
a wide range of pixel pitch options from 12 mm to 35 mm, fitting to any application
the onboard operating system of the variable message sign provides permanent diagnosis and reports any error status to the central system
full traceability of all used assemblies in the internal data base
a pulse width modulated constant current at a very low level increases LED life time and avoids ageing effects and luminosity losses
use of cutting edge LED technology: only highest quality LEDs from renowned manufacturers are used
higher resolution by small pixel pitch (12mm with RGB) fulfilling strongest EN 12966 requirements (including contrast)
quick and easy replacement of parts without use of tools
reliable power supply for LED displays and controller
optimized stability by proven construction
low weight by weight-saving construction using non-corrosive aluminum or stainless steel reduces costs of structural system
