With the development of the times, the night scene of cities is increasingly adorned by LED streetlights. No matter where you go, those sparkling lights are the direction you pave your way.
LED streetlights are everywhere, illuminating every urban night, ensuring the safety of those returning home. In response to the national call for energy-saving and environmentally-friendly initiatives, LED streetlights are rapidly entering every country and city, being recognized as the most promising green lighting source of the 21st century. Compared with traditional high-pressure sodium lamps, LED streetlights reveal their unique charm.
1. The luminous efficacy of LED streetlight sources has reached 110-130lm/W and can theoretically achieve 250lm/W. In contrast, the luminous efficacy of high-pressure sodium lamps increases only with power. Therefore, the overall luminous efficacy of LED streetlights is stronger than that of high-pressure sodium lamps, achieving energy-saving goals.
2. According to scientific data, the color rendering index of LED streetlights is significantly higher than that of high-pressure sodium lamps. Generally, the color rendering index of high-pressure sodium lamps is around 23, while that of LED streetlights can reach above 75. This means that at the same brightness, the illuminance of LED streetlights can be reduced by more than 20% compared to high-pressure sodium lamps.
3. LED streetlights exhibit minimal light decay; data indicates that their annual light decay is less than 3%. Thus, even after 10 years of use, they still meet the required illuminance. In contrast, high-pressure sodium lamps can have a light decay of over 30% within a year, allowing for significantly lower power design compared to high-pressure sodium lamps for LED streetlights.
4. LED streetlights have a long lifespan, operating for over 50,000 hours, and come with a 3-year quality guarantee. Compared to traditional high-pressure sodium lamps, they save considerable costs. Their automatic energy-saving features can adjust power consumption for different periods, reducing energy usage. Importantly, they do not contain harmful metals like mercury, posing no environmental threat upon disposal.
Today, the concept of green and sustainable development is gradually gaining traction, making the future of LED streetlights exceptionally bright.
