LED Street Smarts Street lighting turns to LEDs for longevity and efficiency

摘要

Light-emitting diodes (LEDs) have been appearing in traffic signals and vehicle headlights for years and are poised to affect another source of light we use to navigate our cities and towns. Municipal street lighting retrofitted with LEDs has enhanced several communities' nighttime environments, while significantly reducing energy consumption and maintenance costs. Administrators are well-versed in the financial strains of street lighting. It can account for up to one-quarter of a municipality's electric bill, while maintenance can cost another 15 to 25 percent of their annual operating expense. However, what most municipalities lack, according to Mike Johnson, president, Alloway Electric Co., Boise, Idaho, is basic knowledge of lighting systems and technology.
