LED streetlights are visible almost everywhere in the current social environment. With the development of cities, more people are noticing these streetlights. Their efficiency and safety features have drawn considerable attention, leading many to inquire about the characteristics of LED streetlights.
From a surface perspective, LED streetlights exhibit unidirectional light without diffusive reflection. This feature ensures lighting efficiency. The design of the streetlights incorporates unique optical elements, allowing the light produced to be directed entirely to the designated illumination area, thus enhancing overall lighting efficiency and promoting energy savings.
In practical design, LED streetlights can utilize various design approaches. Currently, they can achieve a power range of 110 to 130 watts, with potential for further development, theoretically reaching up to 360 watts. However, the luminous efficiency of high-pressure sodium lamps tends to increase with higher power. Overall, LED streetlights generally exhibit superior light efficiency compared to high-pressure sodium lamps, especially as the theoretical performance of 250-watt high-pressure sodium lights does not surpass that of LED lights.
The color rendering of LED streetlights is significantly higher than that of high-pressure sodium lamps. The color rendering index of high-pressure sodium lamps is around 23, while LED streetlights can achieve a detection index of over 75, taking into account visual perception, while maintaining equivalent brightness. Meanwhile, the brightness of LED streetlights is approximately 20% lower than that of high-pressure sodium lamps.
