How to prevent the occurrence of lightning? Having been studied,the several ways that were found are the most effective ways to guard against the damage by lightning for the LED road light: 1, set the lightning protection zone Nowadays ,the LED road lights including the LED street light and LED tunnel light in addition to the current power supplies, some communication devices also must be set up to control the switch and the brightness of the LED street light and LED tunnel light,these devices and power are need to be resettled in the lightning protection zones, the protected areas is directly Shield by the Shell. Here’s electromagnetic is much weaker. 2, lightning equipotential bonding To completely eliminate the damage of the potential difference that is caused by lightning, use the overvoltage protection to equipotential connect the power lines, signal lines, metal pipes and so, each inner protection zone at the interface must also be local equipotential connections, the each local equipotential connection must be connected each other, and finally connected with the main equipotential place. 3, combine the external and internal protection lightning Now the exterior LED street light and the LED tunnel light are generally coated with the conductor material,itself is equivalent to a lightning rod, the deflectors and ground network must be installed, the systems constitute the external protection lightning system. The system can avoid the fires and personal security incidents caused by the LED street light and the LED tunnel light due to the direct lightning .the Internal lightning protection system refers to that the ground connection and the voltage protection is set inside the road light to protect the equipment. The system prevents lightning overvoltage and other forms of intrusion, resulting in destruction of the power, which is that the external lightning protection system can not be guaranteed. Both are mutually reinforcing and complementary. Internal protection lightning systems in many devices such as housing, cable in-out protection area, metal pipes, etc. must be connected to the external lightning protection system or set overvoltage protection, and the equipotential connection. 4, high-quality protective equipment – Lightning and overvoltage protection module module SPD’ play the roles in connecting the systems protected to the equipotential protection in the shortest possible time (nanoseconds), so that each port equipment such potential. While the enormous lightning pulse energy generated by the thunder is released into the earth through the short route to reduce the potential difference between the interfaces on both side of the equipment, which play the role of protective equipment. The power supply module of the LED street lamp and tunnel light must not only be designed in accordance with the above requirements, and must undergo a rigorous inspection procedures: 1, the devices with a constant voltage output function or with a constant current output capabilities, or the GB 19510.12 / IEC61347-2-13 safety standards should be used for both of them to test. 2, the control device with the function of only controlling the LED light dark, flashing, change color GB 19510.12 / IEC61347-2-11 safety standards shall are used to test. 3, if a control device with both the above two functions, the GB 19510.12 / IEC 61347-2-13 safety standard should be used to test. Practice has proved that through scientific design and rigorous testing, not only to ensure that the LED street lighting system are not subject to lightning damage, but also to eliminate the interference of the common mode and differential mode the lightning make impact on the power.
