1. An LED light signal, comprising:

  • a signal generator for generating variously colored light spots, said signal generator having LEDs embodied as multicolor LEDs, said signal generator having at least one optical sensor for monitoring a color locus and a light intensity reliably in terms of signaling technology;

    a sensor amplifier;

    an A/D converter;

    a signal box;

    a digital evaluation device, said optical sensor connected via said sensor amplifier and said A/D converter to said digital evaluation device for determining the color locus and the light intensity, said digital evaluation device generating a feedback signal dependent on environmental conditions, including an ambient temperature, and forwarding the feedback signal to said signal box, said signal box generating an activation signal to be applied to said signal generator; and

    means for comparing the feedback signal with the activation signal.
