The issues of light non-visual influence on the human body during the work of office workers and students of educational institutions are considered. The necessity of creating a high-quality lighting environment of educational premises and offices by means of the corresponding dynamic lighting scenario taking into account non-visual effects of visible light is substantiated. The necessity of light levels revision of on working surfaces taking into account circadian effects is shown. The rapid development and increasing growth of LED lighting, which allows to obtain dynamic light scenes, as well as progress in knowledge of physiological mechanisms that regulate circadian rhythms, and their relationship with light stimuli allows to implement really high quality artificial lighting. The light environment not only affects the visual characteristics, but also has a significant impact on people through the so-called non-visual effects or those that do not form images (BOZ-effects) - mood, vivacity, circadian rhythms and more. It is important to combine visual and non-visual requirements with innovative lighting systems. Circadian lighting should always be evaluated at eye level, in the typical location of human existence in a specific internal environment. The improved lighting scenario involves synchronizing the light with the activity and circadian rhythms of consumers over a 24-hour cycle. Lighting in the auditoriums of educational institutions should meet the necessary visual requirements and create comfort for pupils and students. Audience lighting can be more efficient than lighting dynamics or dynamic lighting levels and color temperature. Automatic lighting control, which depends on the dynamics of daylight and should usually be built into the smart installation of dynamic lighting, should be a must.
