Why do I need to use LED protectors?
High-power LEDs offer long life, low power consumption, and low maintenance requirements, which makes them increasingly popular for outdoor applications.
But LEDs are sensitive electronic devices that can be damaged by overvoltage and overcurrent transients caused by system switching, electrostatic discharge and nearby lightning strikes.
In addition, the switch-mode power supplies used with LEDs do not provide the transient protection of the inductive ballasts they replace in lighting applications.
LED String Vulnerability
LEDs are often designed to connect in strings of five to twenty in series. Often the failure of any single LED will take out an entire string.
In street light or airport runway light applications, the loss of the string may dim or shut down the light, creating a safety hazard. In outdoor LED display advertising signs, it may produce blank spots and result in lost revenue.
In any case, the failure of an LED string is often a costly maintenance issue in outdoor applications.
