Lightning has always been a natural enemy of electrical equipment, for integrated light source led industrial and mining lamps, but how to prevent the LED high bay light from being destroyed by lightning?
1. Set lightning protection zone: This is a direct and relatively early method to prevent lightning damage. At present, for long lifetime LED high bay light, in addition to the power supply equipment, some communication devices will be set up to control the switch and brightness of the street lamps. Both the equipment and the power supply need to be placed in the lightning protection zone, and the protection zone is directly shielded by the outer casing.
2. Lightning protection equipotential bonding: In order to completely eliminate the damage caused by lightning, the general electrical appliances must use the overvoltage protector for equipotential bonding, and the local equipotential bonding of the inner protective zone of the LED high bay light should also be carried out.
3. External lightning protection and internal lightning protection: Now, the general led mining lamp is used outside the conductor material, which is equivalent to a lightning rod. The internal lightning protection system refers to the internal protection of the LED high bay light through grounding and voltage protection. The system prevents inductive lightning and other forms of overvoltage intrusion, resulting in power supply damage, which is not guaranteed by external lightning protection systems. The two are complementary and complement each other.
