Street light turns on as the vehicle approaches

Danish scientists have come up with smart street lighting to help turn Copenhagen into the world's first carbon-neutral city by 2025 and save power.

Street lights are being studied to adjust the brightness

Luminaires are fitted with sensors so they only work when pedestrians or drivers are approached. This technology allows to reduce the light of street lights when there are no vehicles and passersby. However, the driver's vision is always guaranteed to make them feel safe. Traffic sensors, air quality, noise, and weather will adjust the brightness best to reduce costs and emissions while still ensuring the required light source.

Chief Engineer Kim Brostrom of the Danish Outdoor Lighting Laboratory said, "The team has installed over 280 signal pillars with 50 different solutions and 10 different power management systems. We also have a lot of on / off sensors in this area. "

In addition, some signal towers are equipped with wind or solar power generators. Scientists estimate that, thanks to the installation of intelligent traffic lights throughout the city, Copenhagen has saved up to 85% of urban lighting costs, according to VOA.

In particular, this system can be easily controlled by connecting to a tablet or smartphone.
