LED teeb pom kev zoo tau hloov pauv lub ntiaj teb teeb pom kev lag luam nrog nws lub zog ua haujlwm, lub neej ntev, thiab cov txiaj ntsig ib puag ncig. Txawm li cas los xij, kev nthuav dav sai ntawm cov khoom siv LED tau ua rau muaj kev txhawj xeeb txogelectromagnetic compatibility (EMC). Kev ua haujlwm tsis zoo EMC tuaj yeem cuam tshuam lwm yam khoom siv hluav taws xob, ua rau muaj hluav taws xob pov tseg, thiab ua rau muaj kev pheej hmoo rau kev noj qab haus huv.
Ib txoj kev tshawb fawb qhia tau los ntawmWang Qingmin et al. (2024)soj ntsuam cov electromagnetic cuam tshuam (EMD) theem ntawm LED teeb pom kev zoo cov khoom lag luam hauv Jining lag luam los ntawm 2021 txog 2023. Cov kab lus no nthuav tawm lawv cov kev tshawb pom, txhawb nqa los ntawm cov ntaub ntawv, thiab muab kev pom zoo rau cov tuam txhab, cov xa tawm, thiab cov kws tshaj lij kev ruaj ntseg.
