1. LED streetlights inherently possess directional light emission, eliminating light scattering and ensuring high luminous efficacy.
2. LED streetlights feature a unique secondary optical design that directs light precisely onto the target illuminated area—the road surface—thereby enhancing luminous efficacy and achieving energy savings.
3. At present, the luminous efficacy of LEDs has reached 100 lm/W, with considerable room for further improvement. The theoretical maximum could reach 250 lm/W. For high-pressure sodium lamps, luminous efficacy increases with power. Consequently, the overall luminous efficacy of LED streetlights surpasses that of high-pressure sodium lamps.
4. LED streetlights exhibit very low light depreciation—less than 3% per year—and can still meet road‑lighting requirements after 10 years of operation.
5. LED streetlights can automatically dim, meeting lighting requirements at different times of day, reducing power consumption, and maximizing energy savings.
6. An LED driver is a low-voltage DC device that supplies power to individual LEDs. It operates at a safe voltage, making it safer than using a high-voltage power supply. LED stage light 、 LED spotlight 、 LED street light It is especially suitable for use in public places.
7. Long lifespan: The theoretical service life exceeds 50,000 hours; it can be switched on and off repeatedly without risk of damage.
8. Easy installation: Simply mount the LED streetlight fixture directly onto the lamp post, replacing the existing sodium lamp holder.
