【 Solar street lamps factory 】 LED street light the necessity of lightning protection

Lightning is a phenomenon of electrostatic discharge, usually carry millions of volts transmitted from the cloud to the ground or other clouds. In the process of transmission, lightning will generate electromagnetic fields in the air, on the induction of kv voltage ( The surge) To the power circuit and generate induction

lightning is a phenomenon of electrostatic discharge, usually carry millions of volts transmitted from the cloud to the ground or another cloud. In the process of transmission, lightning will generate electromagnetic fields in the air, on the induction of kv voltage ( The surge) To the power circuit and generate induced current transmission to a few miles away, these indirect attack occurred often in outdoor exposure of wire, such as street lights, traffic lights, base station equipment such as emission transients. Surge protection module is in the front end circuit directly to surge interference from the power cord. It will surge or absorption of energy transfer and minimize circuit surge threat to other work, such as the LED street lamp lighting lamps and lanterns of ac/dc power supply unit and other equipment. Due to the LED street light than traditional street lamp price roughly twice as expensive, the government purchase in the first place at the time of the investment amount is larger, so you need to in the process of running by saving electricity spending will cost to earn back gradually, therefore, the service life of LED lamp is very important. If LED lights haven't make up for the cost in the investment recovery period is broken, need additional pay for maintenance, repair the manpower cost a times more expensive than when installation. Thus, in the era of the LED, to achieve the effect of the LED save electricity, save money, you need to make sure that its life to achieve the desired, the product shelf life.

with the related requirements highlighted in recent years, domestic 2017, and 2018 have LED street lamp lightning protection related national standards in the review, as shown in table 2. Reference national standards around the world, driving power supply module if only to meet the fourth level ( Line to line 2 kv, LED street lamps, line - 4 kv) , will not be enough to cope with outdoor lighting may face the threat of lightning surge, Suggestions for street lamps with higher level of lightning protection, and USES the lightning protection module. Although the lightning protection module can provide the LED street lamp with lightning protection, but at the same time, its itself also has its own risks. After the lightning protection module aging, will occur at internal overheating reaction, and even a fire. That is to say, the lightning protection module used in the end there is a risk of fire, as shown in figure 2 is a manufacturer of lamps and lanterns for lightning protection module aging device after the fire. Therefore, the safety of the lightning protection module is a very important concept, installation of lightning protection module is a concept, to install a safety of the lightning protection module is further ideas and challenges.
