Street and street lighting LEDs – overview
Lighting plays a key role in ensuring a smooth traffic flow and the safety of residents. At Sai LED Light Repair, we are proud to be one of the leaders in LED streetlight repair across India, but especially covering Delhi NCR, providing a wide range of selected LED luminaires for urban environment. LED street lighting is an energy efficient, durable and cost-effective option for futuristic cities. LED street lighting systems are versatile enough to be easily managed, maintained and monitored. Additionally, the CO2 emission is lower compared to conventional lighting sources, promoting a greener and better tomorrow.
Features and benefits of LED street lighting
The aesthetics and compact design of commercially available LED street light options are well suited to urban architecture and have a long service life and robust performance. The LED Street Light options are energy efficient and provide adequate lighting to ensure a smooth flow of traffic.
Street lamps have greatly benefited from LED technology that produces light by generating radiative recombination of electron holes in solid-state semiconductors, rather than exciting a gaseous medium or heating a thermal radiator in glass enclosures or enclosures. Solid-state lighting technology offers compelling advantages over HID systems, including high-pressure sodium (HPS), low-pressure sodium (LPS), and metal halide (MH) lamps.
The biggest driver behind the switch from HID (HPS, LPS, MH) to LED is the substantial energy savings that LED technology offers. HPS lamps, the most popular public lighting source of all time, can achieve a source efficacy of up to 150 lm / W in high power products, however in real world applications their source efficacy is around 100 lm / W. When ballast and optical losses are taken into account, the efficiency of the HPS public lighting system can be decreased by 30% to 40%. While phosphor-converted LEDs have a potential source efficiency of 255 lm / W, a commercially available source efficiency of more than 200 lm / W, and an economically economical source efficiency between 150 and 190 lm / W. The high efficiency of the source combined with the directional emission pattern of the LEDs and the high power conversion efficiency of the LED drivers enables LED street lights to achieve a system efficacy of more than 140 lm / W and a luminaire efficiency close to 80%. This means that LED street lighting generates between 50% and 100% energy savings compared to conventional technologies.
