Are innovative control features necessary?
Optional but recommended: light sensors, timers, dimming, remote monitoring, energy management. Improves efficiency and reduces maintenance.
How should light and time controls be configured?
Light sensor: auto on/off at dusk/dawn
Time-based dimming: reduces brightness during low traffic hours
Compatible with central control systems
How to determine pole height and spacing?
Residential: 4–6m, spacing 20–30m
Urban main roads: 8–12m, spacing 30–50m
Highways: 12–18m, spacing 40–60m
What is specific to solar LED street lights?
Solar panel orientation: unobstructed, south-facing (northern hemisphere)
Battery capacity: sufficient for ≥2–3 cloudy days
Smart controller to manage charge/discharge
How to verify lumen maintenance under heat?
Conduct LM-80/LM-79 tests
Ensure LED junction temperature <85°C for long life.
What should be checked when choosing suppliers?
ISO9001 / CE / RoHS certifications
Warranty ≥3–5 years
After-sales service and technical support
How to balance cost and quality?
Avoid lowest-price products; focus on long-term energy savings and lifespan.
Consider driver, chip, heat sink, IP rating, and warranty.
What are the key installation considerations?
Ensure vertical alignment and a stable foundation.
Proper torque on bolts, check wiring insulation.
Avoid shading or obstruction to the light beam.
How to manage maintenance and replacement?
Modular design preferred for easy lamp head or driver replacement
Keep installation records (model, date, wiring)
What are common LED street light issues?
Flickering: check the driver or loose wiring
Dim light: check lumen depreciation or dust on optics
Non-operational: check power supply, surge, or sensor failure.
