The non-visual effects estimation of industrial lighting sources

Abstract

The issues of the visible lights non-visual impact on the human body during work, the circadian efficiency of lighting installations are considered, the analysis of fluorescent lamps used to illuminate industrial facilities according to their circadian characteristics is carried out, the need to take them into account when creating an effective industrial lighting installation is substantiated. Lighting systems design is one of the main components of the electric power systems formation for any industrial facility. When choosing equipment for the projects implementation, it is necessary to be guided not only by electrical parameters, but also by lighting technical parameters, since in addition to the power load, lighting is a means necessary for the successful implementation of the planned technological process. It is important to note that the illiterate implementation of the lighting network is a harmful factor and has a detrimental effect on the work and personnel health. Thus, ensuring light comfort, subject to the observance of the standardized illumination for each room, is one of the key tasks that must be solved when calculating and designing a lighting system. A properly designed lighting system has a direct impact on productivity, fatigue, visibility and visual discomfort during work. When choosing light sources to provide a given standardized illumination, various well-known calculation methods are used, but none of them takes into account the factors affecting the provision of visual comfort. The spectral composition of light is an important parameter of artificial light sources, which affects not only visual function, comfort, but also human health. When developing new lighting standards, standards for light sources and assessment of their quality, it is necessary to take into account the parameters that affect human health and well-being.
