Railway signal light system using LED technology

Abstract

The railway signal light system mainly uses incandescent light sources. Meanwhile, these lights operate in regular ON and OFF mode and suffer from fluctuations when a train passes by, these are all unfavourable factors that reduce the life of incandescent lamps. Therefore, the rating working time of incandescent bulbs is often short, leading to the requirements for maintenance conditions and replacement of supplies with a high frequency. This paper presents the solution of using LED technology to replace incandescent bulbs to solve the above problems. In addition, the article also mentions a solution that integrates IoT technology to help collect status data of each lamp in real time and support the deployment of smart maintenance solutions to improve operational efficiency and reliable and stable operation of the system...
