Denmark heads for the bright lights, smart city
LED technology brings cost savings to street lighting, but Caroline Hayes explores how DOLL (Danish Outdoor Lighting Lab) takes street lighting even further with projects to demonstrate how it can contribute to the creation of smart cities.
More manufacturers are implementing sensors in luminaires; it is not an extra cost to mount a sensor on a mast anymore, it is combined in the luminaire.
Another example currently being demonstrated and tested at DOLL are street lamps from Dutch company Tvilight, which adjust brightness based on movement. Sensors that track traffic density, noise, air quality, weather conditions, and ultraviolet (UV) radiation will be fitted throughout the site, and the results monitored in the central control room to assess the degrees of lower costs and emissions that can be achieved.0
