On rainy days, one common concern is lightning protection, especially in summer when rain is often accompanied by thunder. Many places utilize solar street lights, so addressing lightning protection measures for these lights becomes crucial. This issue is a headache for many solar manufacturers, particularly in open highways and mountainous areas where thunderstorms frequently occur. Therefore, the lightning protection measures for solar street lights are especially significant.
The lightning protection work for solar street lights differs from that of ordinary street lights, mainly because the response speed of LEDs is faster than traditional lights, and they have lower voltage tolerance. Considering these aspects, the following points are important:
1. Direct strike prevention: Use the pole as a lightning rod.
2. Grounding: This is crucial; the pole can serve as a discharge body. The grounding network should be determined based on the geological soil conditions, with ground resistance ≤10 ohms. Additionally, the circuit system of the street light should also have grounding selected at appropriate locations.
3. Circuit: Install dedicated photovoltaic DC lightning protection devices. These devices are mainly designed based on the source voltage. During thunderstorms, the circuit of LED street lights may experience a voltage or current surge induced by static electricity or electromagnetic interference, potentially damaging the LED equipment. Therefore, it is necessary to select suitable dedicated lightning protectors for LED power lines to protect against surge voltage, thereby preventing extensive damage to LED street lights in the same area.
In summary, solar street lights integrate solar street lights, garden lights, and other outdoor lighting decorations in research, production, and sales. For more information about solar street lights, please refer to our official resources.
