In the past, it was dark at night in the countryside, so it was inconvenient for villagers to go out. In recent years, solar street lamps in rural areas have lit up rural roads and villages, completely changing the past. Bright street lamps have lit up the roads. The villagers no longer have to worry about not seeing the road at night. However, in actual use, many people report that rural solar street lamps are easy to be damaged. What are the reasons why rural solar street lamps are easy to be damaged? Now let’s have a look!
Reasons for easy damage of rural solar street lamps:
1. Transient overcurrent of rural solar street lamp
This is usually caused by the passing of a large current exceeding the larger rated voltage of the LED light source in a short period, or by over-voltage events such as power grid fluctuation, transient power supply switching noise of the switching power supply circuit, or transient lightning strike.
Although such an event occurred in a short period of time, its adverse effects should not be underestimated. After the LED light source was shocked by electric shock, it does not necessarily enter the failure mode, but it usually causes damage to the welding line and the rest of the parts close to the welding line, reducing the service life of rural solar street lamps.
2. Electrostatic discharge of rural solar street lamps
This is the most common cause of damage to rural solar street lamps. Electrostatic induction is very easy to occur during charging and discharging, and it is very easy to damage the sharp internal structure circuit components of LED light sources. Sometimes, the body can feel that the unexpected electrostatic discharge may lead to permanent damage to the LED light sources of solar lamps. Previously, when LED light sources were just born, many aspects were not well done, Anyone touching it may damage it.
3. The rural solar street lamp is damaged due to overheating
The ambient temperature is also a part of the cause of LED light source damage. Generally speaking, the junction temperature in the LED chip is 10% higher, the light intensity will be lost by 1%, and the service life of the LED light source will be reduced by about 50%.
4. Water seepage damage of rural solar street lamp
The water is conductive. If the solar street lamp in the new countryside seeps, the damage is generally inevitable. However, many solar street lamps are waterproof, and as long as they are not damaged, they will not enter the water.
The above reasons for the easy damage of solar street lamps in rural areas are shared here. Solar street lamps are constantly being updated and upgraded. The previously fragile solar street lamps are also becoming durable and solid. So don’t worry. As long as basic protection is done, solar street lamps will not be easily damaged.
