Lighting system control for everyday and therapeutic purposes
(2021) Mashkov, V.
The goal of this article is to provide a method for controlling an LEDbased, scalable lighting system. It is known that the spectral characteristics of ambient light affect the natural production of hormones cortisol and melatonin and to a great extent govern the circadian rhythm of living organisms. We provide a solution that allows controlling certain spectral characteristics of the illuminator’s luminous flux in order to mimic those of daily solar radiation. Into account are also taken users’ age group, their momentary desire for the magnitude of the luminous flux and possibilities for therapeutic applications aiming to reduce some hormonal imbalances. Damaging the natural circadian rhythm of living organisms has been known to cause a number of short and long term side-effects, increase risk of dementia, certain types of cancer and other neurodegenerative deceases.
