Method for generating mixed light colours

A method for avoiding physiological phenomena such as color separation or stroboscopic effects that occur under boundary conditions in the case of intermittent feeding in particular of light-emitting diodes, for additive superposition to form color-locus-variable mixed light, whereby the emission br...

Summary:A method for avoiding physiological phenomena such as color separation or stroboscopic effects that occur under boundary conditions in the case of intermittent feeding in particular of light-emitting diodes, for additive superposition to form color-locus-variable mixed light, whereby the emission brightness that can be represented by a periodic duty ratio of a pulse-time-modulated constant current feeding-preferably within the respective period-is realized by changeover to other or between different constant current intensities in such a way that a brightness equivalent, namely once again the current-time integral of the predetermined, brightness-determining duty ratio, arises in the current area sum, which now preferably no longer exhibits gaps over the period.
