Abstract (en)
[origin: CA2803968A1] The invention relates to an LED light signal, in particular an LED railway light signal, comprising a signal generator (1) for generating varicoloured light spots, wherein the LEDs are embodied as multicolour LEDs, in particular RGB LEDs (10) - Red (11) /Yellow (12) /Blue (13) LEDs. In order to be able to utilize the possibilities for colour mixing and thus for realizing a large number of colour variants for safety-relevant signalling technology, the invention provides for the signal generator (1) to have at least one optical sensor (15, 15.1, 15.2) for monitoring the colour locus and the light intensity reliably in terms of signalling technology.
