street lighting

A streetlight is a light, typically mounted on a pole, that is part of a series spaced along a public street or highway. These lights are a form of artificial illumination, a key element in architecture and interior design. Historically, lamps evolved from simple vessels with wicks to more complex gas and electric lighting systems.123

Early street lighting often utilized gas lamps. The development of electric lighting, particularly arc lamps and later incandescent lamps, revolutionized street illumination. In the 20th century, sodium-vapour lamps became widely adopted for street lighting due to their efficiency and ability to penetrate fog. High-pressure sodium-vapour lamps provide brighter, whiter light suitable for areas like road intersections and stadiums. Modern lighting technologies, including LEDs, also contribute to street illumination.342
