Method for LED luminaire flux control when simulating sunlight

The aim of this study is to develop a method for controlling an LED lighting system without feedback, in which the spectral characteristics of the luminous flux mimic the daily changes of summer sunshine. At the same time, the spectral composition of the radiation and the magnitude of the luminous flux can be adjusted depending on the desire of the users, their age peculiarities, and possibilities for therapeutic influence to prevent the development of depressive states, etc.
