Bio and electromagnetic compatibility of shipboard lighting systems based on ledlight sources
Nowadays, LED light sources are introduced in shipboard lighting systems. Modern LED lamps and fixtures are non-linear electric loads for the shipboard electric power system, and their operation is associated with the emission of electromagnetic interference. At the same time, the characteristics of their optical radiation, and, consequently, its impact on the ship's crew (bio-compatibility), depend on the parameters of electrical energy in the shipboard electric power system. A variety of characteristics of available LED products and insufficient development of the issues of bioelectromagnetic compatibility of LED light sources determine the relevance of this study. Main problems of ensuring the bioelectromagnetic compatibility of LED lighting systems are revealed in the paper. The analysis of requirements to electromagnetic compatibility in ship systems is given. The results experimental research and mathematical modeling are given to consider problems of the operation of ship lighting systems in the presence of distorting loads. The impact of LED light sources on the supply network and the ship's crew is assessed.
