The importance of street light lightning protection is determined by the concept of payback period. Since the price of LED street lights is about twice as expensive as that of traditional street lights, the government invests a large amount at the beginning of the purchase, so it is necessary to gradually earn back the cost by saving electricity expenses during the operation process. Therefore, the life of LED lights is very important. If the LED explosion-proof light is broken during the payback period before the cost is recovered, it needs to be repaired at additional cost. The labor cost for maintenance is twice as expensive as that for installation. Therefore, in the LED era, to achieve the effect of LED power saving and money saving, it is necessary to ensure that its lifespan can meet your expectations, that is, the product has a long shelf life. To achieve cost savings and ensure that street lamps are not damaged during the payback period, it is necessary to increase the reliability. This requires adding lightning protection modules to LED street lights to maximize economy.

In addition to the necessary lightning protection performance, another important performance of the power surge arrester is its safety performance:

1. Does not affect the function of the system;

2. When the protective device fails, the impact on the system operation is minimized.

The lightning arrester is a consumable, it must start the protection action prior to the protected equipment, and ensure that the protected equipment is protected prior to the damage of the protected equipment. Only by understanding lightning protection from the component level can a basically qualified SPD be delivered to customers.
