Influence of illumination on creation of comfortable working conditions

Introduction. In modern society, different types of lighting fixtures with a variety of shapes, colours and brightness are widely used. However, not all of them effectively fulfil their functions and can negatively affect human health. Optimal lighting parameters are identified, taking into account safety and energy efficiency. Key aspects include the analysis of the spectra of incandescent, fluorescent and LED lamps using a spectrometer and assessing their impact on the vision and mental health of employees working in an office space through a written survey.Materials and methods. The illuminance, luminous flux and economy of workstations in office premises were analyzed.Results. The analysis of the obtained results allowed to determine the rationality of application of the investigated spectra of different types of lamps. The results of the research will be useful both for specialists and manufacturers in the field of lighting engineering, as well as end users.Conclusions. Recommendations for the use of LED lamps as the main source of lighting in office-type premises are given. These lamps provide an almost uniform spectrum, which creates optimal conditions for vision and reduces the negative impact on mental health. It is proposed to supplement the workspace lighting with individual light sources in the form of desk lamps of a yellowish shade at each employee's workplace. LED lamps are not only energy efficient, but also contribute to the formation of a comfortable and safe working environment.
