LED driver module to help more than 85% of the traffic lights
Time:2017-07-15

 

2016 international traffic fair recently held in Amsterdam, SIEMENS for the first time to the world to uncover the mystery of the "one watt technology". The technology will increase the energy efficiency of traffic lights by more than 85%, bringing huge benefits to the city budget and the environment. 

 Now, a typical intersection based on light bulb technology, equipped with about 55 traffic lights (red light, yellow light and green light) can reduce harmful carbon emissions by more than 6000 kg per year. This is due to the use of the latest research results, known as the "one watt technology". At present, Italy city of Bolzano and the southern German city of bietigheim bissingen is to carry out the first batch of pilot projects. 

"One watt technology" uses digital LED driver module, so the signal lamp device is no longer used to consume most of the power of the load resistance and switching elements. The very low power dissipation of the LED technology can still keep the light intensity. In addition to saving electricity, a watt signal lamp device can also reduce maintenance costs. Optical monitoring device for sustainable check LED status. It can be expected that the future will be able to predict the device will be at what time of failure, so as to signal lamp device for preventive maintenance. 

It is understood that, if you do not use these high energy efficiency traffic lights, such as the city of Berlin to be planted about 2000 trees to compensate for the carbon emissions caused by the. Still in use a lot of incandescent lighting and LED is not the city, saving electricity and reduce emission potential will be much greater if installed in a typical cross a tile red light, less than 5 years can recover costs.
