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.Fault detection system in signaling pilots for motor vehicles. Especially intended for signaling pilots (1) based on luminescent diodes or LEDs (2), it is materialized in a circuit that incorporates a comparator block based on a diode (D {sub, 2}), a zener diode (DZ) , an operational amplifier (IC) and several resistors, an output characterization block, based on a transistor (T), a diode (D {sub, 3}) and several resistors, and optionally a protection block (C {sub, 2} -C {sub, 3}), so that the aforementioned comparator block controls by voltage the drop in consumption in the electronic circuit to be analyzed, that is, in the, leds (2), with the voltage or voltage reference set in the characterization block of the output, so that when the actual voltage is higher than the reference voltage, the operation is considered to be correct, while when the actual voltage is lower than the reference voltage, the operation of the pilot (1) is incorrect and as such a luminous device is out of regulation
