How to choose LED roadway lights?
Reliable Manufacturer
1. Check production capacity, experience (at least 5 years), and knowledge.
2. Ensure a robust supply chain and competitive pricing from countries like China.
3. Verify testing reports for quality assurance.
LED Components Quality
1. Opt for reputable LED chip brands (CREE, OSRAM, Philips, etc.).
2. Choose manufacturers with skilled electrical engineers for custom PCB design.
3. Consider LED encapsulation technology for enhanced reliability and performance.
LED Driver Quality
Select reliable LED drivers from well-known brands (MEAN WELL, OSRAM, etc.).
Heat Sink
Check for die-cast aluminum casing for efficient heat dissipation.
Height of roadway lights
Average height of different roadway lights
roadway lights come in various heights to suit different road types and locations. High-pole roadway lights, ranging from 10-15 meters, are installed on major roads with heavy traffic. Middle-pole lights (6-8 meters) are found on urban secondary roads, while low-pole lights (3-5 meters) are used in rural areas and residential paths.
Factors that influence the height of roadway lights
Factors influencing height include road width, with the height matching the width or half if on both sides. Vehicle height matters for main roads, and LED wattage affects brightness, with higher wattage requiring taller lights (e.g., 100 W LEDs at 7 meters, 200 W LEDs at 12 meters). Other considerations include speed limits, crime rates, total light output, and distribution. Properly designed and placed roadway lights enhance safety and aesthetics, reducing accidents by 30%-50%.
Lifespan of LED roadway lights
Factors Affecting Lifespan
1. Temperatures: LED lights are sensitive to temperatures. Ideally, they should operate between -40 °C and 50 °C. Higher temperatures reduce lifespan, luminous efficiency, and can cause faults in electronic components. Proper heat dissipation is crucial for performance improvement.
2. Humidity: High humidity can lead to rusting of electronic components and PCB boards, affecting reliability and service life.
3. Driver Quality: The quality of LED drivers varies. Choosing high-quality drivers with reliable ICs, transformers, and a well-executed soldering process is essential for longevity.
4. Position: The location of LED roadway lights impacts their lifespan. Lights in high-traffic areas, such as crossroads, may have a shorter service life due to potential collisions.
What makes the lifespan of LED roadway lights longer
1. Material: High-quality components, including LED chips, heat dissipating materials, and PCB boards, contribute to a longer lifespan.
2. Process: Strict adherence to design requirements and proper execution of the production process are crucial for longevity.
3. Storage and Transportation: Avoiding unfavorable conditions like mechanical vibration, humidity, and high temperatures during storage and transportation helps maintain the quality of LED roadway lights.
4. Installation and Maintenance: Following proper usage rules and conducting regular maintenance, including timely replacement of broken parts, extends the service life.
