Evaluation of the Efficiency of Lighting With Leds of Industrial Premises

Abstract

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 work of an industrial nature. In the course of research work, an experimental lighting installation (ELF) was developed and installed, which implements lighting options with LEDs and fluorescent lamps (LL). The state of the accommodative-muscular apparatus, the retina and the central link of the organ of vision was assessed; integrated indicators of visual performance were studied. It has been established that LED lighting does not have a negative impact on the organ of vision and the human body as a whole, indicators of visual performance. The changes in the functional parameters of the organ of vision that take place during the performance of visual work enter the corresponding boundaries of physiological fluctuations and are reversible. It was revealed that second-generation LEDs create a more favorable light environment for performing visual work of an industrial nature. The practical significance of the obtained results is shown.
