Why use an LED protector? High-power LEDs are increasingly used in outdoor applications due to their long life, low power consumption, and low maintenance requirements. However, LEDs are sensitive electronic devices, and over-voltage and over-current transients caused by system switching, electrostatic discharge, and nearby lightning strikes can cause damage to the LEDs. In addition, switching power supplies used in LEDs do not provide inductive ballast transient protection in lighting applications. LED light string defect Typically, LEDs are designed with 5 to 20 strings in series. Failure of a single LED often results in the entire string not working properly. In streetlight or airport runway lighting applications, failure of the light string can result in dimming or no illumination, posing a safety hazard. Blind areas can appear in outdoor LED display billboards, resulting in lost revenue. In any case, for outdoor applications, LED string failures often mean high maintenance costs.
