Analysis on the Ignition(fire) Risk of LED Lighting According to SMPS Wiring Status
초록
영어
As civilization develops and the quality of life gradually increases, modern society now values development centered on eco-friendly and energy conservation, not just the development of civilization. accordingly, existing incandescent lamp are being replaced by LED lighting that high efficiency and lifespan. the government is also operating a policy to convert fluorescent lamp into LED lighting by 27 year. for the above reasons, the use of LED lighting is gradually increasing, but most consumers are not aware of the risk that can occur in LED lighting. according to recent statistics, the number of lighting and sign fires has been decreased every year, but the number of LED lighting fires has been continued to increase every year. to use LED lighting, SMPS that convert AC into DC is essential. therefore, in this study, we would like to analyze the ignition(fire) risk of LED lighting according to SMPS wiring status. furthermore, we would like to analyze the problems and suggest improvement measures.
