Open LED Protectors

Littelfuse, Inc. (Chicago, IL) has developed a new line of open LED protectors optimized to provide superior protection against open LEDs. The PLED6M Series LED protector is designed to provide a switching electronic shunt path when an LED in an LED string fails as an open circuit. This ensures that the entire array of LEDs will continue providing illumination even if a single LED in the string fails. The new LED protectors provide greater lighting reliability in applications where uninterrupted illumination is critical, such as street, subway, runway, and tunnel lighting, as well as vehicle headlights, roadside warning lights, and outdoor signage.
