G56 Expressway Lighting: 1,680 Smart LED Street Lights

Hangzhou, China – SAHUNG, a premier provider of intelligent outdoor lighting solutions, has successfully completed a major infrastructure lighting upgrade for the G56 Hangzhou-Rui Expressway (Zhejiang Section). This critical transportation artery, stretching 123 kilometers through the mountainous terrain of western Zhejiang, now features over 1680 sets of SAHUNG’s high-efficiency Smart Street Light Series, significantly enhancing nighttime driving safety and operational sustainability.

The G56 Zhejiang section is a vital link connecting Hangzhou to the Anhui border at Yulingguan. Characterized by its complex geography—including dense bridges, tunnels, steep slopes, and sharp curves—the expressway faces significant safety challenges, particularly during night-time and adverse weather conditions like rain and fog. With heavy flows of long-distance freight and tourist traffic, reliable illumination was paramount.

SAHUNG deployed its 180W and 240W Smart Street Lights across key high-risk zones, including:

• Interchange Ramps: Ensuring clear visibility for merging traffic.
• Lake-Crossing Bridges: Providing uniform light distribution over water surfaces to prevent glare and dark spots.
• Critical Water-Adjacent Road Sections: Enhancing contrast and depth perception for drivers.

The transition from traditional sodium vapor lamps to SAHUNG’s advanced LED technology has delivered immediate, quantifiable benefits for the highway authority:

• Superior Visibility: The new LEDs offer significantly higher brightness and lower glare compared to legacy systems, improving driver reaction times in foggy or rainy conditions common to the region.
• Energy Savings: The project has achieved an estimated 40% reduction in comprehensive energy consumption.
• Reduced OPEX: With a luminous efficacy of 140LM/W and extended lifespan, the long-term maintenance costs and electricity bills have been drastically lowered, aligning with green infrastructure goals.

The lights installed utilize SAHUNG’s latest optical design, specifically engineered for wide-road applications.

• Model: Smart Street Light Series (180W/240W)
• Efficacy: 140LM/W
• Key Feature: Precise light distribution control to minimize light pollution while maximizing road surface uniformity.

"This project demonstrates our ability to handle large-scale, complex municipal infrastructure projects," said a SAHUNG project representative. "By tailoring our lighting solutions to the specific topographical challenges of the G56 expressway, we aren't just selling lights; we are delivering a safer travel experience and a sustainable energy model."

SAHUNG specializes in R&D, manufacturing, and sales of high-end LED lighting products. From industrial facilities to municipal infrastructure, we provide customized lighting solutions that combine energy efficiency with superior performance.
