Tubular LED (TLED) teeb yog ib yam ntawm LED teeb tsim los ua kom rov zoo cov khoom siv hluav taws xob fluorescent, yog li siv cov txiaj ntsig ntawm LED thev naus laus zis, xws li kev siv hluav taws xob thiab kev ua haujlwm ntev. Muaj peb yam tseem ceeb ntawm TLED teeb: Hom A, uas ntiav tus tsav tsheb sab hauv thiab ua haujlwm nrog lub teeb fluorescent uas twb muaj lawm; Hom B, uas siv tus tsav tsheb sab hauv thiab hla lub ballast kom txuas ncaj qha rau kab hluav taws xob; thiab Hom C, uas suav nrog tus tsav tsheb sab nraud uas hloov cov ballast uas twb muaj lawm. Txhua lub teeb hloov kho no tuaj yeem hloov mus rau hauv lub teeb pom kev kub ntxhov, siv ntau hom kev siv tshuab xwm txheej ceev raws li nws qhov tshwj xeeb kev faib tawm. Qhov no tsuas yog kev pom zoo; Cov kws tshaj lij hluav taws xob lossis cov neeg ua haujlwm muaj peev xwm yuav tsum tau siv los hloov LED retrofit fixtures rau hauv cov teeb pom kev kub ntxhov.
Hom A
Hom A TLED retrofit teeb ua haujlwm ncaj qha rau cov raj fluorescent tam sim no tau teeb tsa hauv koj qhov khoom siv. Lawv tau siv los ntawm cov zis ntawm thawj AC fluorescent ballast.
Hom B
Hom B TLED hloov lub teeb muaj inbuilt tsav tsheb uas hloov alternating tam sim no (AC) hluav taws xob mus rau tam sim no (DC) voltage rau energize lub LED array. Cov teeb no yog tsav ncaj qha los ntawm AC kab thiab qee zaus hu ua "bypass" TLED teeb lossis "mains operated" TLED teeb.
Hom C
Hom C TLED hloov qhov muag teev ua haujlwm ntawm DC fais fab mov, zoo ib yam rau lub tshuab hluav taws xob nyob ruaj ruaj. Yog hais tias TLED hloov lub teeb tsis muaj inbuilt tsav tsheb, AC LED tsav tsheb nrog DC voltage tso zis yuav tsum tau siv los hloov lub fluorescent ballast.
Retrofit TLED Emergency Lighting Considerations
Tej zaum kev txhawj xeeb txog kev sib raug zoo yuav tshwm sim thaum rov kho cov khoom siv hluav taws xob qub nrog cov cuab yeej siv tam sim no. Ib qho teeb meem tshwm sim hauv daim ntawv thov tshwm sim thaum cov khoom siv teeb pom kev kub ntxhov fluorescent twb tau teeb tsa ua ntej kev txhim kho.
Kev teeb tsa fluorescent ua ntej tuaj yeem muajthaum muaj xwm ceev ballastuas yog incompatible nrog TLED teeb. Hauv qhov piv txwv no, nws yog ib qho tseem ceeb kom tshem tawm cov teeb meem kub ntxhov tam sim no thiab hloov nws nrog cov khoom tsim nyog thaum muaj xwm ceev sib xws nrog hom tshwj xeeb ntawm TLED lub teeb (hom A, B, lossis C). Lub hnub nyoog ntawm cov khoom siv thaum muaj xwm ceev tam sim no kuj yuav tsum raug coj mus rau hauv tus account. Txawm hais tias qhov kev sib raug zoo ntawm qhov kev kub ntxhov tam sim no nrog TLED qhov muag teev lossis nws muaj hnub nyoog tshaj li tsib xyoos, nws raug nquahu kom hloov nws. Qhov kawg tshwm sim yog lub kaw lus tsim los xa ob peb xyoos ntawm kev saib xyuas- ua haujlwm pub dawb thaum koom nrog cov kev nce qib tshiab tshaj plaws hauv lub teeb cav thiab teeb pom kev kub ntxhov.
Kev nce qib hauv lumen efficiency ntawm LED thev naus laus zis piv rau fluorescent thev naus laus zis tuaj yeem ua qhov zoo ib yamteeb pom kev kub ceevconfiguration siv tsis tau. Qee qhov xwm txheej, ob lub fluorescent fixtures yuav tsum tau ua raws li cov qauv kev nyab xeeb ntawm lub neej. Txawm li cas los xij, kev txhim kho lumen tso zis ntawm LED teeb pom kev zoo tuaj yeem tsuas yog ib qho khoom siv txaus.
Ntxiv nrog rau lumen efficiency, lub teeb dispersion yog qhov tseem ceeb ntawm kev ua haujlwm uas cuam tshuam rau lub teeb pom kev kub ntxhov. Lub teeb fluorescent feem ntau yog omnidirectional, txawm li cas los xij feem ntau TLED qhov muag teev txwv lub kaum sab xis, yog li cuam tshuam lub teeb faib ntawm qee lub luminaires.
