A signal transmitter contains at least one first luminous element, at least one second luminous element and an interface for connecting the signal transmitter to a signal box. A drive device is connected between the interface and the at least two luminous elements and the drive device is configured in such a way that, in the case of a switch-on signal coming from the signal box for the second luminous element, the drive device controls the activation of the luminous element depending on the signaling state of the first luminous element.

Signal transmitter

An LED light signal, in particular an LED railway light signal, contains a signal generator for generating varicolored light spots. The LEDs are embodied as multicolor LEDs, in particular RGB LEDs&#x2014;Red/Yellow/Blue LEDs. In order to be able to utilize the possibilities for color mixing and thus for realizing a large number of color variants for safety-relevant signaling technology, the signal generator has at least one optical sensor for monitoring a color locus and a light intensity reliably in terms of signaling technology.
