Intelligent street lighting

From Wikipedia, the free encyclopedia

Intelligent street lighting refers to public street lighting that adapts to movement by pedestrians, cyclists and cars in a smart city.[1] Also called adaptive street lighting, it brightens when sensing activity and dims while not. This is different from traditional stationary illumination, and that which dims on a timer.

History[]

Europe[]

The first patent requests for intelligent street lighting stem from the late 1990s.[2] But it wasn't until April 7, 2006, that Europe experienced the first large scale implementation of a control network in a street lighting application. The implementation took place in Oslo (Norway) and it was expected to reduce energy usage by 50 percent, improve roadway safety, and minimize maintenance costs.[3]

The Oslo project triggered interest from other cities in Europe, and formed the basis for other sustainability initiatives, such as the E-Street initiative. This research group focused on ways to reduce energy usage in outdoor lighting systems in the European Union (EU). The E-Street group strongly influenced EU standards and legislation for intelligent outdoor lighting systems.[4]

Features[]

Street lights can be made intelligent by placing cameras or other sensors on them, which enables them to detect movement (e.g. Sensity's Light Sensory Network, GE's "Currents", Tvilight's CitySense).[5][6] Additional technology enables the street lights to communicate with one another. Different companies have different variations to this technology. When a passer-by is detected by a camera or sensor, it will communicate this to neighboring street lights, which will brighten so that people are always surrounded by a safe circle of light.[7] The SmartLighting technology of the Anhalt University of Applied Sciences does this as well, and has been installed in Bernburg-Strenzfeld in Germany.[8] Street lights illuminate at a longer distance ahead of the pedestrian than behind the pedestrian in the SmartLighting concept.

Control[]

Some companies also offer software with which the street lights can be monitored and managed wirelessly. Clients, or other companies, can access the software from a computer, or even a tablet. From this software, they can gather data, pre-set levels of brightness and dimming time; receive warning signals when a light defects.[9][10][11]

Guidelines[]

The U.S. Federal Highway Administration has issued guidelines to provide a process by which a governmental agency or a lighting designer can select the required lighting level for a road or street and implement adaptive lighting for a lighting installation or lighting retrofit.[12]
