This article presents the issues related to the functioning and reliability and operational analysis of light-emitting diode (LED) type lighting modules, which are used in the railway technology. These devices operate in different electromagnetic environment conditions in the vast railway area. In the railway area, there are intentional and unintentional electromagnetic (stationary and mobile) interference which affect the operation process of the LED type lighting modules. In the article, the electromagnetic compatibility tests of the lighting module with a converter were carried out with the use of the electromagnetic interference (EMI) receiver of the ESCI3 type and the NNB-51 artificial network. As a result of the carried-out electromagnetic compatibility (EMC) tests, the exceeding of permissible levels of the value of conducted interference emissions was found. The electromagnetic interference of this frequency range has an impact on the operation process of the lighting module with a converter, therefore, by using the appropriate relationships, the values of the probabilities of the system staying in the distinguished operation states were calculated (e.g., in two states of partial suitability distinguished in the LED lighting module due to parallel coupling through reference impedance Z and capacity C). The considerations presented in the article related to the LED type lighting module with regard to electromagnetic interference allow for numerical assessment of different types of (technical and organisational) solutions that can be implemented in order to minimise the electromagnetic interference impact on the system functioning.

包括电磁干扰的 LED 照明模块的可靠性-运行分析

本文介绍了与铁路技术中使用的发光二极管 (LED) 型照明模块的功能和可靠性以及运行分析相关的问题。这些设备在广阔的铁路区域内在不同的电磁环境条件下运行。在铁路领域，存在有意和无意的电磁（固定和移动）干扰，影响LED类照明模块的运行过程。文章中，利用ESCI3型电磁干扰（EMI）接收器和NNB-51人工网络，对带转换器的照明模块进行了电磁兼容测试。作为执行的电磁兼容性 (EMC) 测试的结果，发现超出了传导干扰发射值的允许水平。该频率范围的电磁干扰对带转换器的照明模块的工作过程有影响，因此，通过使用适当的关系，计算系统停留在不同工作状态的概率值（例如，在由于通过参考阻抗 Z 和电容 C 的并联耦合，在 LED 照明模块中区分了两种部分适用状态。
