ОСВІТЛЕННЯ ВХІДНОЇ ГРУПИ З ЕЛЕМЕНТОМ РЕЖИМУ ОЧІКУВАННЯ ДЛЯ ЗАКЛАДІВ ЦІЛОДОБОВОЇ РОБОТИ.

Purpose. The main purpose of the study is to create energy-efficient solutions when designing the lighting of the entrance group for the case when the object must provide round-the-clock operation Methodology. To achieve this goal, a method for multi-level connection of light sources of different intensities has been developed. The control of the processes of level regulation is carried out using motion sensors. Results. The modern level of LED products makes it possible to use LED lighting sources as universal ones, allowing you to implement any design solution. The introduction of motion sensors as elements for regulating the intensity of light allows to obtain more than 50% energy savings. Interesting design solutions help create light accents without creating too much lighting on certain objects. Scientific novelty. The work combines multilevel lighting systems using motion sensors as switches operating at night. The authors proposed a sequence of connecting the levels of the system to create the most comfortable stay and a good first impression of the institution. Such a system makes it possible to use lighting not only for practical purposes, but also for the most attractive visual appearance. Practical significance. The versatility of this methodology allows it to be applied to objects of various purposes, including round-the-clock service. However, it is important to plan for such a lighting system even at the design stage of the building in order to obtain the maximum economic benefit. [ABSTRACT FROM AUTHOR]
