How To prevent the light malfunction Solar Post Lights; 6 Easy Tips

Today, solar post lights are gradually replacing the traditional post lights and more regions will use the environmentally friendly and energy saving solar street lights in the future. Present solar street lights generally use LED as light source, but it is often the case that the light doesn’t go on when in use. And this is the phenomenon that we always called “light malfunction”.

What causes a solar post lights malfunction?

Light malfunction of solar street lights is caused by two reasons: First, the high leakage current result in the PN junction failure and light malfunction, but does not influence the entire light.

Second, the disconnect of internal connection lead of solar post lights result in no current pass through, causing light malfunction and the entire light cannot function properly.

How to prevent the light malfunction of the solar post lights?

1. Prevent static electricity

Static electricity is an extremely scary and harmful monster for LED. It will damage or permanent failure the LED if any issue occurs. Static electricity in the human body can reach around 3000V, enough to breakdown the LED chip. Therefore, it is required to have a scientifically standardized grounding design at the LED assembly production line.

2. Use the automatic welding equipment

Strict welding temperature must require in manual welding. When the temperature is too high, it will cause light malfunction as well. Use the soldering iron for welding process, with the temperature higher than 300-400℃. Light malfunction will occur when the temperature isn’t control well.

3. Replace faulty components

To prevent light malfunctions on solar post lights, it is important to regularly inspect all components of the light. If any component is found to be faulty, such as the LED bulb, solar panel or battery, it should be replaced immediately. Faulty components can cause the light to malfunction, so replacing them will ensure that the light operates properly.

4. Check the battery

The battery is a critical component of solar post lights, as it stores energy from the solar panel to power the light at night. Regularly checking the battery and ensuring that it is fully charged is important to prevent light malfunctions. If the battery is not charged properly, it can cause the light to dim or not turn on at all. Check the battery regularly and replace it if necessary.

5. Check the wiring

The wiring in solar post lights is responsible for transmitting the energy from the battery to the light, so it is important to check the wiring regularly. Loose or damaged wiring can cause the light to malfunction or not turn on at all. Check the wiring and connections regularly and tighten any loose connections or replace any damaged wiring to prevent malfunctions.

6. Clean the solar panels

Dirt, debris, and other obstructions can prevent the solar panels from absorbing sunlight properly, which can cause the light to dim or not turn on at all. To prevent this, clean the solar panels regularly with a soft cloth and gentle cleaning solution. Make sure to remove any dirt or debris that may have accumulated on the panels, paying close attention to any corners or edges where dirt may collect. By keeping the solar panels clean and unobstructed, you can ensure that the solar post lights receive the maximum amount of sunlight and operate properly.

Conclusion

Above is how to prevent the light malfunction of the solar post lights. The coefficient of expansion of LED lead wire under high temperature is several times higher than the coefficient of expansion at about 150℃.

The inner gold spot welding will pull away the welding joint because of the thermal expansion and contraction, causing light malfunction. Therefore, efficiently prevent light malfunction of the solar street lights will extend the service cycle of the street lights.
