[Customer Profile]
Liuliqiao is a major traffic hub situated on Beijing’s Third Ring Road, serving as a critical artery for the city's high-volume vehicular flow.
[Scope of Work]
The intersection's original lighting infrastructure consisted of nine 1000W high-pressure sodium (HPS) lamps mounted on six 35-meter high-mast poles. The facility required a comprehensive lighting upgrade to significantly reduce energy consumption and modernize the illumination quality while maintaining adequate visibility for nighttime traffic safety.
[The Solution]
The project executed a strategic retrofit, replacing the legacy HPS lamps with eighteen 200W LED floodlights utilizing a 2800K color temperature. This upgrade achieved a remarkable 66.67% energy-saving rate. The optimized system now delivers an average illuminance of 33 lx with a uniformity ratio of 0.56, maintaining a maximum illuminance of 68 lx and a minimum of 23 lx to ensure safe and consistent road visibility.
