Smart Street Lights-Not Only About Energy Savings

As much as half of a city’s electricity bill is from simply powering streetlights which are not always needed. Europe pays over €10 billion each year only to power streetlights that burn when no-one needs really them. By adopting smart technology for street lights, utilities have the potential to save a great deal of money.

Another example is the Tvilight system, designed by Tvilight-a Dutch startup, which works by sensing movement-whether it’s a cyclist, vehicle or pedestrian. Once movement has been detected, the lights respond instantly by shining brightest where they are most needed. Other lights further afield will remain dim. Instead of just one light, the system illuminates multiple lights all around a moving vehicle or pedestrian. The sensors inside are also smart enough to know not to activate the lights when a bird flies by, or when wind moves tree branches. The system can even tell what type of object is approaching; since a car moves faster, the lights around it are a bigger diameter and start brightening farther down the block.
