In order to increase pedestrian and vehicular safety, street lights are utilized to brighten nearby areas and roadways. Typically, street lights are among the most valuable components of a city’s infrastructure. They improve security and safety in residences, workplaces, and city centers by providing secure roadways in large public spaces. Major, collector, and local roads with high pedestrian and bicycle traffic volumes are equipped with street lighting. Streetlights are used to illuminate roads, bikeways, walkways, pathways, bridges, ramps, tunnels, curbs, parking lots, driveways, roadway barriers, drainage structures, utility structures, and other outdoor areas. They can also be found at the intersection of a road and a sidewalk or possibly in a harbor facility. High-intensity discharge lamps, often high pressure sodium lamps, are used in most existing road illumination (HPS). Although the power supply designs have been relatively straightforward, the fixtures’ light quality, efficiency, and controllability have not been optimal. The push for increased energy efficiency has made light emitting diode (LED) technology more popular as a replacement for high-pressure sodium (HPS) lighting in commercial and municipal settings.

Because they use less energy, last longer, and provide better illumination than incandescent, fluorescent, and high pressure sodium lamps, LED street lights are a great alternative. LED street lights combine great energy economy with outstanding optical performance. Prominent brand names like CREE, Philips Lumileds, Osram, and Bridgelux provide light sources that are very bright, have a broad beam angle, a high CRI (color rendering index), and a respectable rate of luminous flux maintenance. Die cast aluminum, used to make the housing, is powder coated in a tough epoxy primer finish that provides exceptional resistance to abrasion, corrosion, and UV deterioration. Because the driver is designed to increase light output and energy efficiency, the street light fitting is an excellent option for any application involving street lighting. The active PFC feature, short circuit, over current, over voltage, and over temperature precautions are all included into this universal AC input full range power supply. Along a road or walkway, light is distributed uniformly via a specially made lens. In order to protect LED life, an inbuilt self-monitoring sensor automatically reduces heat load when it senses temperatures over the tolerance. In addition to making power supply and light module replacements significantly easier, the modular architecture allows for IP66 lighting protection.

Intelligent controller modules installed on top or bottom of pole fixtures may be used to monitor, control, and manage street lights. Multi-way control functions, such as remote control, time control, and brightness control, are available for LED street lighting. They are designed to be turned on at night and off throughout the day. Additionally, they may be set up with a light sensor so that the street lights only come on at night. At some periods, a central timer may trigger the activation of a street light or a group of street lights, even if the light sensor provides input. There may be periods of reduced traffic for cars and/or pedestrians during the chosen hours.

An increasing amount of luminaires are powered by solar energy due to the earth’s greenhouse effect and energy scarcity. A photovoltaic panel, which is part of a solar street light, collects solar energy and transforms it into electric power. This electric power is then sent to a lighting unit, which is what produces light. The battery’s charging process, load operating levels, and load operating durations are all controlled by related circuitry. In addition to the solar cells, the solar-powered LED street light needs mains electricity as well, allowing for an interchangeable power source.
