To prevent the street lights are the most effective way to destroy lightning:

1, external lightning protection and internal lightning combination:

General LED lights are outside the conductor material, itself is equivalent to a lightning rod, the design must be installed off the assembly line and the ground network, these systems constitute an external lightning protection system. The system can avoid LED lights due to direct lightning caused by fire and personal safety accidents. Internal lightning protection system refers to the internal lighting through the ground, set the voltage protection, etc. to protect the device. The system prevents the induction of lightning and other forms of overvoltage intrusion, resulting in power damage, which is outside the lightning protection system can not be guaranteed. Between the two is complementary, complement each other. Internal lightning protection system In many devices such as the shell, access to the protection zone of the cable, metal pipes and so on to connect the external lightning protection system or set the overvoltage protection, and equipotential bonding.

2. Lightning equipotential bonding:

In order to completely eliminate the destructive potential difference caused by lightning, power lines, signal lines, metal pipes and so on to use over-voltage protection device for equipotential bonding, the inner protection area of the interface should also be local equipotential bonding, each Local equipotential junctions are connected to each other and finally connected to the main equipotential sites.

3. Set the lightning protection area:

LED lights in addition to power equipment, but also set up some communications equipment used to control the switch and brightness of street lamps, these devices and power supply need to be placed in the lightning protection zone, the protection area directly shielded by the shell. The electromagnetic field here is much weaker.
