FIELD : physics, optics.SUBSTANCE : invention relates to field of lighting engineering and, in particular, to LED sources of white light based on dark blue (450-455 nm), green (525-535 nm) and red (605-615 nm) light-emitting diodes, named after RGB integration as a triad. The method of obtaining of modified trichromatic sources of white light by means of application on RGB triad of light-emitting diodes of suspension of dark blue light-induced luminophor, meanwhile the luminophor functions are performed by the activated cerium with the composition LnAlOof off-stoichiometric composition, where Ln - yttrium or together with it one or several rare earth elements containing excessive Ln in relation to Al so what the value of the coefficient ? varies within the interval 0
