PULSATION OF LIGHTING AS A NEGATIVE LIGHT ENVIRONMENT FACTOR
The paper considers the impact of quality indicators of artificial lighting sources (pulsation, flicker effect) on the health and productivity of workers associated with the voltage of the visual analyzer. Information is given about the negative influence of the pulsation factor not only on the organs of vision, but also on other functional systems of the body (central nervous system, cardiovascular system, circadian rhythms). It is shown that the existing regulatory requirements for the quality of the lighting environment of industrial premises do not adequately reflect the relevance and significance of this indicator of lighting to ensure a favorable production environment and a rational labor process. The results of a study of the lighting parameters of light sources (including the ripple coefficient) are widely used in practice. Significant differences of this indicator were revealed depending on the type of sources and the technology of their manufacture (manufacturing company). Recommendations are proposed on minimizing the consequences of the harmful and dangerous effects of pulsations of the light flux of sources by means of input control of its magnitude by comparatively simple laboratory methods.
