ON THE HYGIENIC EFFICIENCY OF LIGHTING WITH LEDS IN INDUSTRIAL PREMISES

The article is devoted to the description of experimental studies on the assessment of the hygienic efficiency of lighting conditions with light emitting diodes (LEDs) of the first and second generations when performing industrial work. In the course of the research work, an experimental lighting installation (ELI) was developed and installed, able to implement lighting options with LEDs and fluorescent lamps ( FL). The state of the accommodative-muscular apparatus, the retina and the central link of the organ of vision was assessed; integral indicators of visual performance were studied. It was found that the illumination with LEDs does not have a negative effect on the organ of vision, the human body as a whole or indicators of visual performance. Changes in the functional indicators of the organ of vision occurring during the performance of visual work are within the corresponding boundaries of physiological fluctuations and are reversible. It was revealed that second generation LEDs create a more favourable light environment for performing visual work of a production nature. The practical significance of the results obtained was shown.
