Do you know the reason for the glitches of the street lights?

Here are some minor conditions and reasons for streetlights that may appear.

1. The whole set of solar street lights is not bright

The whole set of solar street lights does not light up, the possible reasons are incorrect wiring, problems with the light source, short circuit of the water inlet controller of the line, too long continuous rainy days, etc. First, check the controller of the solar street light, look at the signs above, check whether the corresponding marked lines are connected correctly, and then observe whether the terminals of the controller have watermarks and rust. If there is a possibility that the controller is damaged, if not, measure the Battery voltage, 12V solar street light system battery voltage is lower than 10.7V, the battery can no longer be used, replace the battery. When there is light on a sunny day, check whether the solar panel has current and voltage output. If there is, the solar panel is normal, and if not, the solar panel is damaged. If none of the above problems exist, there is a problem with the light source of the led lamp. Connect the light source to other power sources to check whether the light is on, and if it is not on, change the light source of the lamp. If it is several rainy days in a row, the whole set of solar street lights does not light normally, because the solar panels do not generate electricity, and the electricity stored in the battery has been used up. When there is light on sunny days, the solar panels continue to charge the battery, and the solar street lights will light up normally.

2. LED light source flickering

The main reason for the flickering of the LED light source is the wiring problem, or the battery may be out of power. First of all, check whether the wiring is correct and whether the connections and packages of each node are normal. You can also reconnect the lines. If the light source is still flickering, it is necessary to consider that the battery is out of power. Measure the open-circuit voltage of the battery with DC voltage. If the voltage is lower than 12v, the battery is depleted. Connect the positive and negative poles of the battery to the positive and negative poles of the solar panel correctly. After charging for 1-2 days, the system can be used normally.

3. The lighting time is short, and it will not light up when it rains

There is only one reason for this kind of failure. The capacity of the battery is too small. If it is newly installed, it means that the battery capacity issued by the manufacturer is false and cannot meet the lighting requirements for continuous rainy days. If the solar street light has been used for several years, It means that the battery has decayed to its service life, and the battery can be replaced.

4. The light source of led lamps is not fully bright

Some parts of the light source of Led lamps are bright, and some places are not. At present, the LED light sources of solar street lamps commonly used in the market are formally arranged, and some of them are bright and some are not bright, indicating that the quality of the LED lamp beads is not good or the specifications are not uniform, resulting in the same voltage and current. It may also be that there is virtual welding during the welding process, and some lamp beads are in poor contact. In this case, just replace the LED light source, and the solar street light will be on normally.
