Led Lamp Head-LED Light Head Replacement on Zhuhai Avenue Municipal Road
Zhuhai is situated in the southwestern part of the Pearl River Delta Metropolitan Economic Circle, one of China’s three major economic core circles. It is one of the first four special economic zones implementing the opening-up policy and the core city on the west bank of the Pearl River Estuary.
Spanning 45 kilometers in total, Zhuhai Avenue serves as a vital traffic artery connecting the eastern and western urban areas of Zhuhai. As a major thoroughfare linking core cities within China’s three major economic circles, it delivers invaluable value and driving force to the economic development of Zhuhai and the entire Pearl River Delta Metropolitan Circle.
Municipal roads including Zhuhai Avenue serve not only as express corridors for economic development, but also as demonstration routes for people’s livelihood improvement. However, insufficient road lighting has posed severe safety hazards to pedestrian and vehicle traffic, while failing to enhance the overall urban image.
To address this issue, relevant authorities in Zhuhai will replace the existing light fixtures with mature and reliable LED lamp heads on Zhuhai Avenue and other municipal roads to upgrade the road lighting system.
As a comprehensive solution provider for municipal road outdoor lighting in Zhuhai, Sanxing Lighting integrates Zhuhai’s unique urban culture and characteristics to improve road illumination brightness and overall lighting environment quality. It has independently developed and innovatively manufactured the Led Lamp Head, which serves as the mainstream lighting fixture for Zhuhai Avenue, Zhuhai Bridge, Niwanmen Bridge, Jinwan Interchange, Airport East Road and other key municipal roads.
The lamp body is die-cast from aluminum alloy, with surface passivation followed by spraying of outdoor-specific plastic powder.
Adopting a unique optical and heat dissipation structural design, the lamp ensures efficient and reliable operation. It delivers a rectangular road light spot with a left-right light distribution angle over 145°, guaranteeing excellent road brightness uniformity.
The light source adopts a modular structure. A breather valve is installed in the light source cavity to balance internal and external pressure, eliminate internal fog and condensation, and stabilize luminous flux output while extending service life.
Color temperature: 3750K~4250K; Luminous efficacy: over 130LM/W.
Light distribution: Semi-cutoff type. Equipped with professional optical-grade light distribution lenses, with customizable light distribution angles for different application scenarios.
Ingress Protection Rating: IP65.
The heat sink is integrally die-cast from high thermal conductivity aluminum alloy, featuring high interchangeability, superior protection level, excellent heat dissipation and long service life.
Externally fitted with ultra-clear tempered glass cover, it resists dust and oil contamination and maintains high luminous flux retention rate for outdoor application.
A breather valve equipped in the light source cavity balances internal and external pressure, removes fog and condensation inside the cavity, and ensures stable luminous flux output as well as prolonged LED service life.
The lamp adopts one-click opening structure for easy later maintenance. Made of aviation-grade 6063-T5 aluminum, the material undergoes chromate treatment then outdoor-grade powder spraying, providing over 10 years of corrosion resistance.
Through-type Heat Dissipation Design
The upper and lower through-type heat sink imitates the combustion principle of honeycomb coal. Solid coal burns slowly and incompletely due to insufficient air contact at the center; after adding through-holes, air convection accelerates combustion, known as the thermal honeycomb effect. Similarly, the integrated heat sink is divided into segmented units with ventilated gaps between them to form air convection, rapidly dissipating heat and lowering the heat sink temperature by 20℃.
One-Click Power Compartment Opening
High-toughness tempered elastic strips enable quick opening of the lamp rear cover. This design holds independent intellectual property rights and greatly improves installation and maintenance efficiency.
Modular Structural Design
The lamp adopts a combined multi-module structure. Each module is connected in series or parallel via waterproof connectors and compatible with various power supplies. The adoption of standardized modules also promotes the standardization of road lighting fixtures.
Imported Flip-Chip and High-Efficiency Power Supply
Adopting advanced gold-free eutectic welding technology, imported LED flip-chips are directly soldered onto ceramic substrates with gold balls. The gold-free design expands the light-emitting area, boosts luminous efficacy, avoids LED open-circuit failure, and minimizes thermal resistance. The customized driver power supply features a power factor above 0.9 and efficiency up to 92%.
Premium Optical-Grade Light Distribution Design
The lens is made of imported optical-grade PC material with light transmittance over 92%. The customized brightness-based light distribution design achieves top-tier industry test performance. Most domestic manufacturers design purely based on illuminance for convenient on-site measurement, which creates even ground illuminance but ignores actual visual perception for drivers and pedestrians. Higher illuminance uniformity often leads to poorer road lighting effect and more severe zebra-stripe glare. Our products fully meet national brightness and illuminance standards when installed in accordance with CJJ45-2006.
New-Generation LED Glass Module
The new-generation LED street light module adopts medium-power 3030 LED beads with EMC brackets for higher luminous efficacy. Matched with imported optical-grade PC lens and high-strength ultra-clear tempered glass with high light transmittance, it resists dust accumulation and maintains long-term high brightness. With light transmittance over 92% and scientific brightness-oriented light distribution, it reaches leading industry performance and effectively relieves driver visual fatigue. Built with high thermal conductivity die-cast aluminum heat dissipation structure and surface powder coating, it offers stronger corrosion resistance and a large heat dissipation area for optimal cooling performance.
