Sitraffic One: The world‘s first 1Watt Technology

Whether particularly economical, particularly safe or particularly compact: our LED signal heads convince in all traffic situations and areas of application.

Silux2 Very Low Power (VLP) signal heads are particularly economical and safe.

How can we make absolutely sure that intersecting traffic flows do not receive a “green light” at the same time?

Yunex Traffic provides the answer with the first signal head with SIL3 certification. With its multi-layer monitoring concept, Silux2 VLP achieves the highest safety standard in road traffic (SIL3). What’s more, Silux2 VLPs are particularly economical: thanks to the Very Low Power version, they consume only 1 to 2 watts of energy, up to 80% less than previous 230 V LED signal heads. How you benefit:

  • Safe and reliable signal monitoring
  • Preventive LED maintenance
  • Integrated microprocessors for the collection and analysis of even large amounts of data

How do I implement a traffic light that consumes only 1 Watt?

Sitraffic One is the world’s first solution for the complete “1-Watt intersection” with SIL3 safety standard – because Sitraffic One works with the innovative Silux2 VLP monitoring technology. This is how the probably most economical traffic light in the world works: 

Sitraffic One

  • No analog load resistors and switching elements in the signal heads.
  • Uses digital LED driver modules and state-of-the-art light emitting diodes with particularly low power consumption.
Sitraffic One reduces the power consumption of a traffic light signal to 1 to 2 Watt.
Safety in small format: the small signal heads from Yunex Traffic

How can safety for cyclists be increased at traffic junctions?

The small signal heads from Yunex Traffic allow separate red and green phases to be switched at intersections for cyclists and can also be used as an auxiliary or additional signal for signaling in special situations. For more safety.

Brilliant optics even at high ambient brightness

The new Silux2 signal heads shine with brilliant optical properties and even better luminous intensity distribution. As a result, almost all versions of the Silux2 signal heads achieve the highest phantom class 5 and are clearly recognizable even when the sun is low – a real contribution to even better road safety.

Reliable and long-lasting

Silux2 signal heads are based on quality all around. Durable and robust components, particularly reliable and efficient control modules (drivers), a very stable and reliable LED technology as well as improved thermal management ensure particularly long lifetimes and high availability.

Easy change of symbol masks

All Silux2 LED signal heads have interchangeable inserts for the different symbols. The symbol masks are inserted into the removable front lens and can be easily turned and changed on site thanks to the integrated door with bayonet lock.

Electronic monitoring ensures high security

Each Silux2 LED light source has an electronic monitoring function. Current and voltage values of the LEDs are permanently monitored and controlled. If the values exceed or fall below the limit values, the input power is immediately interrupted so that the signal is safely switched off.

Dimmable versions avoid glares at night

With the Silux2.230LPD and Silux2.230D signal head models, it is possible to activate a night-time reduction of the light intensity. In this way, the symbols cannot outshine and possibly cause glare to drivers due to the lower light intensity. And another advantage: The lower light intensity saves additional electricity.

Easy to upgrade

The new Silux2 signal heads are available not only as complete signal heads in Ecolight or Classic housings, but also as a upgrade kit, so that existing systems can also benefit from the current generation of LED signal heads with little effort.

Compatible with the Sitraffic controller family

The Silux2 LED signal heads work optimally together with the Sitraffic controller family. This means that even small cities and municipalities can implement efficient and environmentally friendly traffic management.
