In the implementation of outdoor lighting projects, many overseas engineering contractors and purchasers often confuse the selection standards of roadway led lighting for urban main roads, secondary roads and branch roads. Improper lamp matching will not only fail to meet municipal lighting specifications, but also cause energy waste, substandard lighting and project acceptance failures. With years of experience in the foreign trade lighting industry and exposure to a large number of outdoor lighting projects, I deeply understand that standardized model selection and Strict quality control LED engineering lighting are the core keys to successful road lighting projects. Meanwhile, matching with tailored Smart outdoor light solutions can better adapt to the upgrading needs of modern urban lighting projects.
In accordance with China's national standard CJJ45-2015 for urban road lighting design and universal overseas engineering specifications, the differences between LED street lights for the three types of roads are mainly reflected in four core dimensions: illuminance parameters, lamp type, power configuration and functional design.
As the core traffic passages of cities, urban main roads feature large traffic flow and fast driving speed, requiring the highest standards for lighting stability, brightness uniformity and glare control. LED street lights for main roads adopt cut-off or semi-cut-off professional lamps, with an average illuminance of 20-30lx and a lighting power density strictly controlled within 0.85W/㎡. The lamp power is generally 150W-250W with a fixed color temperature of 4000K-5000K, which ensures a clear driving view at night, eliminates glare interference, and fully meets the high-intensity lighting requirements of urban main roads and expressways.
Urban secondary roads are mainly responsible for regional traffic diversion with moderate vehicle and pedestrian flow, and their lighting standards are slightly lower than those of main roads. Equipped with semi-cut-off lamps, secondary road LED lighting requires an average illuminance of 15-20lx and a maximum lighting power density of 0.80W/㎡, with applicable power ranging from 80W to 150W. These lamps balance excellent lighting performance and energy efficiency, and support bilateral symmetrical lamp arrangement with a spacing of 35 to 40 meters. They can fully meet daily traffic lighting needs while effectively reducing municipal energy consumption, ideal for urban commuting roads.
Urban branch roads are mostly auxiliary passages for communities and streets, dominated by pedestrian and non-motor vehicle traffic with basic lighting demands. LED street lights for branch roads usually have a power of 30W-80W and a required average illuminance of 8-10lx. Semi-cut-off lamps with flexible selection can fully meet the usage requirements. Focusing on basic lighting and safety assistance, these lamps avoid excessive brightness, effectively guarantee residents' night travel safety, and deliver high cost performance and low energy consumption.
Many overseas customers hold the misconception that higher brightness means better lighting effect. In fact, precise scenario matching, strict engineering quality control and customized smart lighting functions are the essence of high-quality road lighting projects.
