It was introduced to the US by inventor Benjamin Franklin, who was the postmaster of Philadelphia, Pennsylvania.

An LED street light or road light is an integrated light-emitting diode (LED) light fixture that is used for street lighting.

Traffic lights , also known as traffic signals, traffic lamps , traffic semaphore, signal lights, stop lights, robots and traffic control signals (in technical parlance), are signalling devices positioned at road intersections, pedestrian crossings, and other locations to control flows of traffic.

Intelligent street lighting refers to public street lighting that adapts to movement by pedestrians, cyclists and cars.

The complexities of transportation infrastructure mean varying types of illumination are needed to ensure traffic flows smoothly, people feel safe, and cities save on costs. Philips LED street lighting systems are smart and . The painting was inspired by streetlights at the Piazza Termini in Rome. Street lighting in the District of Columbia is provided by the District of Columbia Department of Transportation, and covers all city streets and alleys in Washington, D. There are two varieties of such lamps: low pressure and high pressure. Low-pressure sodium lamps are highly efficient electrical light sources, but their yellow light restricts applications to outdoor lighting such as street lamps. The streetlights of downtown Main Street in Liberal, Kansas, have old-time character, but they spill light in all directions and up into the sky.

With no shielding, the exposed globes cause glare, making it difficult to see. Sometimes streetlights are poorly designed or installed incorrectly and end up . See what people are saying and join the conversation. Cree lights streets and roadways with the incredibly efficient XSP Series Streetlight.

In addition to fulfilling their primary purpose of casting light onto dark roadways, parking areas, and public spaces, outdoor lighting systems are increasingly evaluated for how well they reduce energy consumption, improve safety for . All of those LEDs, with their new urban color scheme, will dramatically change how . With digital networks and embedded sensors, they collect and transmit information that help cities monitor and respond to any circumstance, from traffic and air quality to crowds and noise. They can detect traffic congestion and track available parking spaces.

Like me, you might have welcomed this development. LEDs are, after all, the most energy-efficient lighting . Use our app to report street light issues in Vancouver.
