Intelligent street lighting refers to public street lighting that adapts to movement by pedestrians, cyclists and cars. Intelligent street lighting, also referred to as adaptive street lighting, dims when no activity is detected, but brightens when movement is detected. This type of lighting is different from traditional, stationary illumination, or dimmable street lighting that dims at pre-determined times. ==History (Europe)==
The first patent requests for intelligent street lighting stem from the late 1990s.〔http://patents.justia.com/patent/6204615〕 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.〔http://www.gizmag.com/go/5475/〕 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.〔http://www.gizmag.com/go/5475/〕
