Abstract. Color mixing models to obtain white light with a predetermined values of correlated color temperature and brightness are presented. One model describes mathematical algorithm for combination of spectra for WW LEDs lighting systems, and other one for systems based on RGBW LEDs. Results of testing of created sample of LED light source for indoor lighting (“Amstrong” type) with implemention of presented color mixing models are shown.

Keywords: smart lighting system, color mixing, RGBW and WW LEDs, correlated color temperature, brightness, Planckian locus.
