The reasons for short lighting time or no lighting on rainy days include: aging and power loss of the battery, dirty or blocked photovoltaic panels, faulty charging circuits, and insufficient configured power.

Cause of constant brightness/non-extinction during the day: Reverse connection of the positive and negative poles of the photovoltaic panel, faulty light-controlled probe, damaged controller.

Causes of low charging efficiency: incorrect orientation/inclination of photovoltaic panels, dust accumulation, and line loss.

Excessive voltage drop in the circuit (dimmer lights at the far end) is caused by factors such as too thin cable diameter, excessively long circuit length, and uneven load distribution.

Solution: Use thicker cables, implement segmented power supply, and add transformers.

Causes of grounding/lightning protection deficiencies: Failure to implement grounding and lightning protection measures, leading to a high risk of lightning strikes and electric leakage.

Causes of inconvenient maintenance: The lamps are installed too high/too densely, the junction box is sealed too tightly, and there is no access hole, making it difficult to replace parts in the later stage.

Timing/light control malfunction (not turning off when it's day/not turning on when it's dark) Causes: photosensitive probe obstructed, timer malfunction, wiring error, unstable voltage.

The entire group/line is not working due to: damaged transformer/power supply, short circuit in the main line, air switch tripping, or controller failure.

Causes of remote control/smart control failure: signal interference, receiver malfunction, pairing loss, wiring issues.

Causes of water accumulation on the lampshade/internal condensation: aging/damage of the waterproof rubber gasket, failure of the sealant, blockage of the breather valve, and improper sealing during installation.

Hazards: Short circuit, corrosion of circuit board, damage to light source.

Abnormal heating of the lamp body / hot shell causes: poor heat dissipation design, drive overload, dense LED beads, poor ventilation, high ambient temperature.

Hazards: Accelerated light decay, driver burnout, safety hazards.

Causes of lamp post tilt/foundation loosening: insufficient foundation size/strength, inadequate concrete grade, failure to comply with wind pressure/geological design, and non-standard installation.

Causes of shell rusting/component aging: Poor corrosion resistance of materials, corrosion in outdoor environment, and lack of maintenance.

Villa courtyards, municipal squares, park scenic areas, tourist attractions, family entrance halls, birthday parties, festive decorations, and many other scenarios。

It has a lifespan of 3-5 years under normal use. Avoid short-circuit damage caused by voltage mismatch and conductive failure damage caused by immersion in water.

Reasons for the complete failure of lighting fixtures: power outage / air switch tripping, fuse failure, open/short circuit in the wiring, oxidized and poorly connected connectors, burned light source, damaged driver/ballast, controller malfunction.

Troubleshooting: Measure input voltage → Check air switch/fuse → Test circuit continuity → Clean oxidized terminals → Replace light source/driver.

The causes of frequent flickering/intermittent dimming of lights include: large ripple in the driving power supply, unstable constant current, voltage fluctuation, poor contact, excessive voltage drop in the circuit, aging of LED beads, and moisture-induced short circuits.

Troubleshooting: Test drive output → Reinforce connectors → Use thicker cables → Replace drive.

Causes of significant brightness decay/dimming: LED light decay (commonly observed after 3-5 years), excessive temperature due to poor heat dissipation, decreased driving current, dust accumulation on the lampshade, and line voltage drop.

Troubleshooting: Clean the lampshade → Measure the drive current → Check the heat dissipation → Replace the aging light source.

Cause of partial LED beads not lighting up/missing colors (RGB/multicolor lights): single LED bead burnout, poor soldering, drive channel failure, poor contact of signal lines.

Troubleshooting: Replace faulty LED beads → Repair welding → Check signal lines.

Causes of severe glare: excessive angle of the luminaire / direct exposure to human eyes, lack of anti-glare structure, too wide beam angle, improper installation height.

Impact: Dazzling, affecting pedestrian safety, and causing light pollution.

Uneven lighting / zebra-like pattern caused by factors such as unreasonable lamp spacing, mismatched beam angles, obstructions, and inconsistent power.

Color temperature/abnormal color, RGB color jumps randomly, uncontrolled causes: DMX512 signal interference, sub-control failure, wiring error, a faulty light fixture dragging down the entire line, controller program disorder.

Troubleshooting: Disconnect the signal in sections → Check the headlight → Inspect the sub-control wiring → Replace the faulty light fixture.

Causes of light pollution/spill light: Poor light distribution design, lack of shading cover, incorrect orientation of lighting fixtures, resulting in light rays directed towards the sky or indoors.
