Qhov ntau ntawm qhov sib txawv ntawm LED teeb hlaws Vf tsis tau pom tias, ua rau tsis tshua muaj kev cuam tshuam ntawm lub teeb thiab txawm tias tsis ruaj khov.
Qhov kev thauj khoom kawg ntawm LED luminaire feem ntau yog tsim ntawm ntau ntawm cov hlua LED txuas nrog hauv kab khiav, thiab nws qhov kev ua haujlwm voltage Vo=Vf * Ns, qhov twg Ns sawv cev tus naj npawb ntawm LED txuas nrog hauv series. Yog li, qhov khiav hauj lwm voltage ntawm LED teeb lub teeb meem sib haum rau VoL ntawm qhov kub thiab txias, thiab qhov ua haujlwm ntawm qhov hluav taws xob ntawm LED teeb nyob rau qhov ntsuas kub tsawg sib xws rau VoH. Hauv LED tsav tsheb, koj yuav tsum xav txog kev tsav tsheb tawm voltage ntau yog tshaj li VoL. ~ VoH.
Yog hais tias qhov siab tshaj plaws qhov tso zis hluav taws xob ntawm qhov hloov LED tsav tsheb qis dua VoH, lub zog siab tshaj plaws ntawm lub luminaire yuav tsis ncav cuag lub zog tiag tiag uas xav tau ntawm qhov kub tsawg. Yog tias qhov hluav taws xob tsawg kawg ntawm lub hloov LED tsav yog siab dua VoL, qhov kev tsim tawm ntawm tus tsav yuav siab dhau qhov ua haujlwm ntawm qhov kub thiab txias, thiab ua haujlwm. Tsis ruaj khov, lub teeb yuav cig thiab lwm yam.
Txawm li cas los xij, xav txog tag nrho tus nqi thiab kev ua haujlwm, peb tuaj yeem' t blindly nrhiav qhov ultra-dav tso zis ntau qhov ntawm cov tsav tsheb LED: vim hais tias cov tsav tsheb voltage tsuas yog nyob hauv qee lub sijhawm, qhov kev tsav tsheb yog qhov siab tshaj. Tom qab qhov ntau dhau lawm, qhov ua tau zoo zog (PF) yuav muaj qhov phem, thiab cov tsav tsheb tawm voltage ntau tsim kom dav dhau, uas ua rau tus nqi nce thiab qhov ua tsis tau zoo dua
