Guidelines for Use of LED
Shunts
Introduction
LED shunts are multipurpose devices which are used in
critical lighting applications to manage LED failures. In a
typical LED lighting application there is a string of LEDs.
Without LED shunts in place, an open circuit failure will
cause an entire string of LEDs to go dark. This concept is
illustrated in Figure 1.
Figure 1. After an LED open circuit failure the entire string goes dark unless LED shunts are used.
