LED Street Lights Avoid Lightning Solutions

Study found several effective ways to prevent LED street lamp damage from lighting.

1.      External lightning protection combined with internal lightning protection

Now the general LED lights exterior are the conductor material which is equivalent to a lightning rod, the design must be installed deflectors and ground network, these systems constitute the external lightning protection system. The system can prevent LED street lights from fire and cause personal safety incidents due to direct lightning. Internal lightning protection system refers to the internal street through the ground, set the voltage protection, and protection of equipment. The system prevents lightning overvoltages and other forms of invasion, destruction caused by the power, which is the external lightning protection system can’t be guaranteed. Between the two are mutually reinforcing and complementary. Internal lightning protection systems in many devices such as housing, access to protected areas and cable, metal pipes, etc. must be connected to the external lightning protection system or set overvoltage protection, and equipotential bonding.

2.      Lightning equipotential bonding

To completely eliminate the damage caused by lightning of potential difference, power lines, signal lines, metal pipes and so use overvoltage protection equipotential bonding. Each inner protection zone at the interface must also be local equipotential connection, various local equipotential connection to connect to each other, and finally connected with the main equipotential place.

3.      Set up lightning protection zone

LED lights in addition to power supplies in current, it will also set up some communication devices are used to control the lights off and the brightness, power of these devices are to be resettled in the lightning protection zones, protected areas directly affected by the Shell Shield. The electromagnetic field is much weaker here.

4.      High quality protective equipment - Lightning and overvoltage protection module

SPD's role is in the shortest time the system will be connected to the equipotential protection systems, so that each port facilities is equal to the potential. While the circuit due to the enormous lightning pulse energy generated by the short route released into the earth, reduce equipment side of the potential difference between the interfaces, which play the role of protective equipment.
