← TechnologyWhich failure propagation occurs when multiple LEDs in series on a single string, used for signage, experience open-circuit failures?
A)Progressive darkening reduces total light
B)Uniform dimming lowers light output
C)Catastrophic whole-string segment shutdown✓
D)Individual LED color temperature shifts
💡 Explanation
Catastrophic string failure happens because of the series circuit wiring: a complete open means no current flow. Therefore, the segment fails completely rather than dimming, because current interruption affects the whole string.
