Surge protector can protect the 100W 150W LED street light from thunder striker several times , prevent the driver and leds from damage .
Surge protector is an electronic device that provides safety protection for various electronic equipment, instruments, and communication lines. When a spike current or voltage is suddenly generated in the electrical circuit or communication circuit due to external interference, the surge protector can conduct and shunt in a very short time, so as to prevent the surge from damaging other equipment in the circuit. Surge protector, suitable for AC 50/60HZ, rated voltage 220V/380V power supply system, to protect indirect lightning and direct lightning or other transient overvoltage surges .
LED street light normally installed at high pole , 3M 5M 7M 9M 11M for different street and application , while rainy days with thunder , espcially the ones in higher pole ,can be thunder striked .
The housing of the ED street lamp is made of aluminium materials, which is equivalent to a lightning rod. In the design, down conductors and ground nets must be installed. These systems constitute an external lightning protection system. The system can avoid fire and personal safety accidents caused by direct lightning strikes by LED street lights. The internal lightning protection system refers to the protection of the equipment by means of grounding and setting voltage protection inside the street lamp. The system can prevent the intrusion of induced lightning and other forms of overvoltage, which can cause damage to the power supply, which is not guaranteed by external lightning protection systems. The two are complementary to each other. The internal lightning protection system must be connected to the external lightning protection system or set with overvoltage protectors on many components such as the housing, cables entering and leaving the protected area, and metal pipes, and equipotential connection is performed.
While the LED street light have surge protector , after the the surge protector damaged , the replacement cost is cheaper and faster than LED driver ,especially if the LED street light is quick maintance design .
The Surge protector for LED street light got parallel and sery connection 2 types for different desire and application .
