How can a LED street lamp protect against lightning strikes?
Generally, the LED street lamps are all conductor materials, and they are equivalent to a lightning rod. Therefore, the power supply of the street lamp must be installed on the lead wire and the ground net. These systems constitute an external lightning protection system. Such a system can avoid fire accidents and personal safety accidents caused by direct lightning in LED street lamps. The interior lightning protection system of street lamp refers to the protection of the equipment in the street lamp through grounding, setting voltage protection, etc.. The internal system prevents incoming lightning and other forms of over-voltage intrusion, resulting in power damage, which is not guaranteed by external lightning protection systems.
Internal lightning protection system must be connected with external lightning protection system of overvoltage protector or set in many devices such as housing, import and reserve cable, metal pipe, and equipotential connection.
One is the external lightning protection system, and the other is the internal lightning protection system, which complement each other and complement each other.
