Prerequisites and Prospects for Establishing Regulations on Artificial Lighting Consistent with Human Biorhythms

Abstract

Today, the current DBN V.2.5-28: 2018, Natural and artificial provides the use of LEDs as a source of light both for lighting the city spaces and for general lighting of premises. In general, the transition of society to digital light-emitting diode technology in lighting is a change in the paradigm that occurs at a rapid pace and relates not only to visual perception and energy efficiency, but also to the optimization of the biological and emotional impact of light. This trend highlights the need for more complete consideration of non-visual light effects in relevant regulations. Therefore, the next step in establishing these regulations should be a set of standards and guidelines for lighting design consistent with human biorhythms. In some countries such documents have already been adopted, which minimizes the risks to human health and safety caused by inappropriate use of new lighting technologies. The article analyzes the following prerequisites for the development of regulations on artificial lighting as the emergence of new data on the impact of light radiation of the biologically active visible range and the near-infrared range on a human body, as well as the widespread introduction of LED technologies that are potentially the most promising tools in reproducing the properties of natural light, synchronization with it and simulating the view from the window. Basing on the analysis of the relevant prerequisites, a list of the most important trends in the development of artificial lighting regulation is proposed: regulation of the presence of the biologically active visible range and the near-infrared range in the spectrum of light systems; determination of the intensity and duration of this radiation, depending on different diurnal periods; development of the technique of correlation of light and visual characteristics of artificial lighting installations and the actual view from the window; synchronization of illumination regulations with regulations concerning application of Li-Fi technology. The issue of energy efficiency of artificial lighting systems consistent with human biorhythms needs to be considered separately in the future publications.
