Outdoor path lights (also known as garden lights, trail lights) are mainly used for lighting in parks, communities, squares and other places. Their installation must meet the requirements of safety, functionality and aesthetics. Understanding the installation specifications and precautions can improve installation efficiency and reduce incorrect operations.
1. Preparation before installation
(1). Design planning
Analysis of lighting requirements: Determine the distance between lamps (usually 3~5 meters), height (0.6~1.2 meters) and illumination standard (10~30 lux) based on the width of the path and the flow of people.
Wiring and power supply:
Use low voltage power supply (12V/24V) or mains power (220V), and give priority to solar LED lamps to reduce wiring.
The cable burial depth is ≥0.5 meters, and is protected by PVC pipes to avoid mechanical damage.
(2). Material and tool preparation
Lamp: waterproof grade ≥IP65, corrosion-resistant material (such as aluminum alloy, stainless steel).
Foundation embedded parts: concrete foundation size ≥30×30×40cm, embedded bolts or anchor cage.
Tools: level, electric drill, cable crimping pliers, insulating tape, etc.
2. Installation steps and technical requirements
(1). Foundation construction
Positioning and laying out: Mark the position of the lamps according to the design drawings to ensure that the straight lines or arcs are aligned.
Pouring the foundation:
Embedded parts must be fixed vertically and the concrete must be cured for ≥3 days.
The foundation should be 5~10cm above the ground to prevent water from soaking.
(2). Lamp installation
Fixing the lamp pole:
Tighten the lamp pole base with nuts and adjust the verticality (deviation ≤2°).
Anchor bolts need to be treated with anti-corrosion (such as anti-rust paint).
Wiring specifications:
Low-voltage lamps: Use waterproof connectors (such as IP67 grade), and the positive and negative poles must not be reversed.
Mains lamps:
The live wire (L), neutral wire (N), and ground wire (PE) are strictly distinguished, and the ground wire is grounded separately (grounding resistance ≤4Ω).
The cable joints are sealed with a double layer of waterproof tape + heat shrink tubing.
(3). Light source and controller installation
LED module: Ensure good heat dissipation and avoid long-term full-load operation. Solar lights:
The photovoltaic panel faces south (northern hemisphere), the inclination angle is ≈ the local latitude, and there is no obstruction.
The battery needs to be moisture-proof and installed in a ventilated place.
3. Safety and acceptance standards
(1). Electrical safety
Insulation test: Use a 500V megohmmeter to measure, the cable insulation resistance ≥10MΩ.
Leakage protection: A 30mA leakage switch must be installed in the mains circuit.
(2). Functional acceptance
Lighting uniformity: No dark areas or glare, the illumination difference between adjacent lamps ≤20%.
Time control: The light control or time control switch must be accurately debugged (such as automatic lighting at dusk).
93). Wind and earthquake resistance
The light pole wind resistance level ≥8 (wind speed 20m/s), and the bolts must be anti-loosening.
4. Maintenance and troubleshooting
(1) Regular maintenance
Monthly inspection: Clean the surface of the lamp and remove leaves that block the photovoltaic panels.
Quarterly inspection: Tighten the bolts and test the ground resistance.
(2) Troubleshooting
| Problem | Possible Cause | Solution |
| Light not lighting | Power outage/controller failure | Check wiring/replace controller |
| Light flickering | Poor contact/unstable voltage | Re-crimp connectors/add a voltage regulator |
| Solar light battery life is short | Battery aging/dirty photovoltaic panels | Replace batteries/clean photovoltaic panels |
