An Indian-origin designer in Holland has developed a new LED street lighting system, known as Tvilight, which illuminates only when it detects people around it.
Dutch designer Chintan Shah and his team collaborated with Delft University of Technology in the Netherlands to develop a sensor, called CitySense, that can detect human presence and provide 360 coverage around a light-pole.
According to Shah, CitySense has two main functions - it dims the light during off-peak hours, but as soon as a person is detected all the surrounding lights glow fully, so they are always in a safe circle of light, CNN reported.
The plug-and-play sensor, integral to the Tvilight lighting network, sends wireless signals to neighboring lights when people are detected.
It can be fitted in both conventional and new LED lights and is a major step towards more sustainable roads.
