ABSTRACT:
The electric traffic light, with acoustic signs and with an indication of backward counting includes lights prepared in three sectors with signaling screens that are controlled by a processor electrically linked to an optic and numeric counter. The circuit of optic formation is programmed in sequence and time to emit activation signals to certain sections of the lights to provide the brightness of the light on each screen. The circuit of the numeric formation is programmed to send signals of interruption of the power supply, simultaneously with the optic circuit, to certain sectors of the lights to provide visualization of numbers. Further, simultaneously with the optic and numeric circuit, a sound emitter emits a sound with each color.
