Abstract
Sistema de detección de fallos en pilotos de señalización para vehículos automóviles. Especialmente destinado a pilotos de señalización (1) a base de diodos luminiscentes o leds (2), se materializa en un circuito que incorpora un bloque comparador a base de un diodo (D{sub,2}), un diodo zener (DZ), un amplificador operacional (IC) y varias resistencias, un bloque de caracterización de la salida, a base de un transistor (T), un diodo (D{sub,3}) y varias resistencias, y opcionalmente un bloque de protección (C{sub,2}-C{sub,3}), de manera que el citado bloque comparador controla por voltaje la bajada dé consumo en el circuito electrónico a analizar, es decir en los, leds (2), con el voltaje o tensión de referencia establecido en el bloque de caracterización de la salida, de manera que cuando la tensión real es superior a la tensión de referencia se considera que el funcionamiento es correcto, mientras que cuando dicha tensión real es inferior a la tensión de referencia el funcionamiento del piloto (1) es incorrecto y como tal dispositivo luminoso está fuera de reglamentación.
