The advances in science and technology have made traditional sodium lamp light sources far inferior to LED light sources in terms of lifespan and color rendering.
Using independently developed high-power LED integrated light sources, equipped with a unique multi-chip integrated single module light source design and imported high-brightness semiconductor chips, these LED lights have high thermal conductivity, minimal light decay, pure light color, and no ghosting.
1. The inherent characteristics of LED street lights – the unidirectionality of light, without light scattering, ensures lighting efficiency.
2. The unique secondary optical design of LED street lights directs light to the desired illumination area, further enhancing lighting efficiency for energy-saving purposes.
3. The efficiency of LED street light sources has reached 90-110LM/W, with significant room for further development. The theoretical value can reach 250LM/W. Unlike high-pressure sodium lamps, which only increase luminous efficiency with higher power, the overall light efficiency of LED street lights is superior.
4. The color rendering index of LED street lights is much higher than that of high-pressure sodium lamps, with a color rendering index of only around 23 for high-pressure sodium lamps, while LED street lights achieve over 75. From a visual psychological perspective, at the same brightness level, LED street lights can reduce illumination requirements by over 20%.
5. LED street lights have low light decay, with less than 3% decay in one year, maintaining road illumination standards even after 10 years of use. In contrast, high-pressure sodium lamps can experience over 30% decay within a year.
6. LED technology operates at low voltage, making it a safer power source, especially for public spaces such as street lighting, factory lighting, automotive lighting, and residential lighting.
7. Long lifespan: LED street lights can last over 50,000 hours; however, the lifespan of power supplies remains uncertain.
