Abstract:
A traffic light that uses lights prepared in three sectors in its signaling screens, different by their placement and internationally normalized color regulation; characterized because it consists in that the screens are controlled by a processor electrically linked to an optic and numeric counter and, in turn, to a device emitter of sounds in which each sector houses a plurality of lights fed by independent sections, which are connected electrically from said optic and numeric counter whose circuit of optic formation is programmed in sequence and time for the emission of activation signals to certain sections of the lights providing the brightness of the light on each screen; simultaneously, the circuit of the numeric formation of said counter is programmed to send signals of interruption of the power supply to certain sectors of the lights, providing visualization of numbers in backwards counting, formed by contrast, between the lights with activation signals and lights with interruption signals, simultaneously and at the beginning of each traffic light activation, said sound emitter is connected electrically to an acoustic means installed in the screen that will receive and emit a distinctive audio-frequency signal for each one of the colors of the screens.
