How to prevent solar street lights from not turning on:
1. Prevent static electricity
Static electricity is a very harmful evil of LED lights. Any problem in a link will cause damage to the LED, degrade the performance of the LED or even fail.
We know that the human body (ESD) static electricity can reach about three kilovolts, which may damage the LED chip. In the LED packaging production line, a scientific and standardized grounding design must be designed. Generally, the ground resistance needs to be 4 ohms. The grounding resistance should even reach ≤ 2 ohms.
2, try to use automatic welding equipment
If manual soldering is used, the soldering temperature must be strictly controlled. This is because manual welding is used. If an ordinary soldering iron is used, the temperature of the soldering iron is higher than 300-400°C. Too high soldering temperature will also cause no light.
The above is a question and answer on how to prevent the phenomenon of solar street lights not turning on. The expansion coefficient of LED wire at high temperature is several times higher than the expansion coefficient at about 150°C. The internal gold wire solder joints will shrink due to excessive thermal expansion. Pull the solder joints apart, causing the phenomenon that the light does not turn on. Therefore, we must regularly repair and maintain solar street lights.
