Currently, the general design of LED street lamps uses conductive materials on the exterior, which acts as a lightning rod. It is essential to install down conductors and grounding systems in the design. These systems comprise the external lightning protection system, which can prevent LED street lamps from catching fire and causing personal safety incidents due to direct lightning strikes. The internal lightning protection system protects the equipment through grounding and voltage protection mechanisms.
1. This system can prevent induced lightning and other forms of overvoltage, which could damage the power supply, something that the external lightning protection system cannot guarantee. The two systems complement each other. The internal lightning protection system needs to connect the external lightning protection system or set over-voltage protectors for various devices, such as enclosures, cables entering and exiting the protected area, and metal pipes, all while ensuring equipotential bonding.
2. Equipotential connections in lightning protection completely eliminate the destructive potential differences caused by lightning. Power lines, signal lines, and metal pipes must be interconnected with over-voltage protectors for equipotential connections. Local equipotential connections must also be made at the interfaces of various inner protection areas, and these local connections should interconnect and connect to the main equipotential point.
3. Establishing lightning protection zones. Currently, LED street lamps additionally feature communication devices used to control the lamps’ switching and brightness, alongside power equipment. These devices and power supplies must be placed within the lightning protection zone, with the protection area directly shielded by the housing. The electromagnetic fields in this area are significantly weaker.
4. High-quality protective equipment – lightning protection modules and over-voltage protection modules. The role of lightning protectors is to connect the protected system to the equipotential system within a time frame measured in nanoseconds, enabling all device ports to maintain equal potential. In addition, immense pulse energy generated due to lightning strikes in the circuit is discharged to the ground via short routes, reducing potential differences at the device interfaces, thereby protecting the equipment.
