Hygienic problems of LED lighting

The work is devoted to the physiological and hygienic safety of the use of LED light sources, the analysis of domestic and foreign materials, the analysis of working conditions and training when using LED lamps. The literature was searched in the databases Scopus, Web of Science, etc.

The study of the biological effect of light on humans remains an urgent problem of lighting hygiene. The authors of the article outlined their attitude to a number of scientific papers on this issue, choosing the most significant ones.

The authors of the article studied over 23 works on the scientific study of the effect of LED lighting on the human body in comparison with fluorescent and incandescent paws.

The studies carried out to assess the impact of LED lighting on the functional state and performance of railway workers using approved professional selection methods revealed negative changes. This was expressed in a slight decrease in the functional resistance to color discrimination of green and red signals, as well as in an increase in the response time of a complex visual-motor reaction and a significant decrease in the readiness for emergency action of the examined persons.

Studies have shown that LED lighting affects not only the eyes, but also the human hormonal system, its psychophysiological state, performance and fatigue.

Ethics. This study did not require an ethics committee opinion.
