FIELD: lighting.
SUBSTANCE: disclosed is a controlled light-emitting diode traffic light. Controlled light-emitting diode traffic light has a light-emitting diode matrix, consisting of N series-connected light-emitting diodes. Matrix is connected through front signal relay contact with current source. Also traffic light comprises field-effect transistor, pulse generator, rear contact of signal relay, standard dynamic element and control relay. Control relay is connected to output of standard dynamic element. Gate of field-effect transistor through rear contact of signal relay is connected to output of pulse generator. Source of field-effect transistor is connected to light-emitting diode matrix and with common leads of pulse generator and standard dynamic element.
EFFECT: higher reliability of traffic light.
