 The object of development is a methodology for modelling the spectral composition of LED light sources for various purposes. The aim of this work is to develop a methodology for modelling the spectral composition of LEDs for various purposes to determine the optimal contribution of spectral components (basic short-wave and broadband photoluminescent) to the resulting radiation to achieve high quality (colour rendering index) and spectral efficiency of the resulting radiation. Research methods - modern research methods were used in the work based on the characteristics of the manufactured experimental samples, and the optimisation of the spectral composition was performed by computer modelling. A methodology for modelling the spectral composition of LED light sources based on blue LEDs and single- or multi-component phosphors has been developed, which allows optimising their light parameters. This allowed performing multi-parameter optimisation of the spectral parameters of LED light sources in order to ensure the most optimal parameters (correlated colour temperature, colour rendering index, etc.) of light-emitting structures, including those for the implementation of special lighting for various purposes.
