Los ntawm ib txwm fluorescent mus rau T8 LED Hnub Teeb Tubes: Daim Ntawv Qhia Ua tiav kom ua tiav qhov ci ntsa iab thiab tus nqi yeej hauv Rhiav teeb pom kev zoo
Nyob rau hauv ib puag ncig muaj kev kub ntxhov ntawm cov chaw tsim khoom, cov tsev khaws khoom, thiab cov chaw ua haujlwm hauv tsev, cov teeb pom kev zoo ua lub luag haujlwm tseem ceeb tshaj li qhov pom tau tsuas yog -nws tsim cov khoom tsim tau, kev nyab xeeb, thiab kev ua haujlwm zoo. Tau ntau xyoo lawm, cov raj fluorescent ib txwm yog qhov kev xaiv zoo rau cov chaw no, muaj nuj nqis rau lawv qhov pib pheej yig thiab muaj dav. Txawm li cas los xij, raws li kev siv thev naus laus zis, kev hloov pauv hloov tau tshwm sim: T8 LED hnub ci raj. Cov lus qhia no qhia txog vim li cas kev hloov pauv ntawm fluorescent mus rau T8 LED hnub ci raj tsis yog ib qho kev hloov kho tshiab tab sis ib qho kev tawm tswv yim uas muab ob qho tib si ci ntsa iab thiab tseem ceeb ntev - txuag nqi, rov hais dua li cas kev cob qhia teeb pom kev ua haujlwm.
Cov raj fluorescent ib txwm muaj, txawm tias lawv nyob ntev - sawv ntsug hauv kev cob qhia, tuaj nrog ntau cov kev txwv uas ua rau muaj teeb meem ntau ntxiv hauv siab -xav tau kev lag luam. Ib qho ntawm cov teeb meem tseem ceeb tshaj plaws yog lawv qhov ci ci tsis sib xws thiab kev poob qis sai ntawm lumen. Tus qauv fluorescent raj yuav pib nrog lub teeb pom kev zoo, tab sis nyob rau hauv thawj xyoo ntawm kev siv, nws tuaj yeem poob txog 30% ntawm nws qhov ci ci. Thaum kawg ntawm nws lub xyoo thib ob, qhov kev poob qis no feem ntau nce mus txog 40-50%, ua rau pom kev tsaus ntuj, tsis sib xws uas tsim cov duab ntxoov ntxoo thiab qhov chaw tsaus nti-kev phom sij hauv qhov chaw uas qhov tseeb thiab kev nyab xeeb yog qhov tseem ceeb. Qhov no fading yuam kev hloov thaum ntxov, cuam tshuam kev ua haujlwm thiab nce kev txij nkawm uas tsis muaj kev cob qhia tsis khoom tuaj yeem them taus.
Lub zog tsis muaj zog yog lwm qhov teeb meem loj ntawm fluorescent technology.Ib txwm 4-ko taw T8 fluorescent rajsiv 32-40 watts ntawm hluav taws xob, tsis tau tsuas yog 20-30% ntawm lub zog ntawd hloov mus rau qhov pom kev; tus so yog nkim li cua sov. Nyob rau hauv ib lub rooj cob qhia loj nrog ntau pua qhov kev sib tw ua haujlwm 12- lossis 24-teev hloov, qhov kev ua haujlwm tsis zoo no txhais tau rau cov nqi hluav taws xob ntau dhau. Nyob rau tib lub sijhawm, cov nqi no sib sau, noj rau hauv cov peev nyiaj ua haujlwm thiab txwv cov peev txheej rau lwm qhov kev nqis peev tseem ceeb. Tsis tas li ntawd, cov cua sov uas tsim los ntawm cov raj fluorescent tuaj yeem ua rau lub tshuab ua haujlwm txias txias thaum lub hli sov, tsim kom muaj lub zog nruab nrab uas ua rau muaj teeb meem.
Kev kho mob taub hau ntxiv plague fluorescent teeb pom kev zoo. Nrog rau qhov nruab nrab lub neej tsuas yog 10,000-15,000 teev, fluorescent tubes yuav tsum tau hloov ntau zaus-feem ntau txhua txhua 12-18 lub hlis nyob rau hauv ib puag ncig-siv tas li. Txhua qhov kev hloov pauv txhais tau hais tias lub sijhawm poob qis, nqi zog, thiab qhov tsis txaus ntseeg ntawm cov khoom seem. Compounding qhov teeb meem no yog lub fragility ntawm fluorescent ballasts, lub Cheebtsam uas tswj lub hwj chim rau cov hlab. Ballasts feem ntau ua tsis tiav ntxov, ntxiv cov nqi kho tsis tau npaj txhij thiab cuam tshuam rau kev ua haujlwm ntxiv. Rau kev cob qhia txhawm rau ua kom muaj txiaj ntsig zoo tshaj plaws, cov kev xav tau kev saib xyuas tsis tu ncua yog qhov tseem ceeb ntawm lub sijhawm thiab cov peev txheej.
Lub teeb zoo kuj tseem yog qhov tsis txaus ntawm cov tshuaj fluorescents. Feem ntau cov fluorescent raj muaj qhov qis xim Rendering Index (CRI) ntawm 60-70, lub ntsiab lus xim zoo li du, distorted, los yog ntxuav tawm. Qhov no yog qhov teeb meem tshwj xeeb hauv kev cob qhia uas cov xim sib txawv yog qhov tseem ceeb-ua haujlwm xws li txheeb xyuas cov khoom siv hluav taws xob me me, tshuaj xyuas cov xim tiav, lossis nyeem cov ntawv zoo ntawm cov schematics raug kev txom nyem los ntawm cov xim tsis zoo, ua rau muaj kev ua yuam kev thiab rov ua haujlwm dua. Tsis tas li ntawd, cov raj fluorescent feem ntau ua rau pom kev flicker thiab buzzing, uas ua rau lub qhov muag strain, mob taub hau, thiab qaug zog ntawm cov neeg ua haujlwm dhau mus txuas ntxiv, cuam tshuam ncaj qha rau kev tsom thiab kev tsim khoom.
Kev txhawj xeeb ntawm ib puag ncig thiab kev nyab xeeb ntxiv lwm txheej txheej nyuaj rau cov teeb pom kev zoo fluorescent. Cov raj no muaj mercury, cov hlau hnyav hnyav uas ua rau muaj kev pheej hmoo rau tib neeg kev noj qab haus huv thiab ib puag ncig yog tias tsis muab pov tseg kom raug. Kev ua raws li cov cai pov tseg uas tsim kev puas tsuaj yuav tsum muaj cov txheej txheem rov ua dua tshiab tshwj xeeb, ntxiv cov nqi thiab kev tswj hwm lub nra kom xaus - ntawm - kev tswj hwm lub neej. Raws li kev ruaj ntseg dhau los ua qhov tseem ceeb ntawm kev lag luam tseem ceeb rau ntau lub koom haum, cov kev cuam tshuam ib puag ncig no ua rau cov raj fluorescent yog ib qho kev xaiv ntau dua.
Piv txwv li,T8 LED hnub ci rajhais txog yuav luag tag nrho cov kev txwv no thaum qhia txog cov kev pab cuam uas haum rau cov kev xav tau tshwj xeeb ntawm kev cob qhia ib puag ncig. Nyob rau pem hauv ntej yog lawv superior brightness thiab uniform illumination. Lub siab -zoo 4-ko taw T8 LED hnub ci raj emits 2,200-2,800 lumens-lub teeb tseem ceeb dua li lub raj fluorescent sib piv-thaum khaws cov khoom tso tawm raws li nws lub neej ntev. Lumen depreciation yog tsawg, nrog LEDs khaws 70-80% ntawm lawv thawj qhov ci ci txawm tias tom qab 50,000 teev ntawm kev siv, kom ntseeg tau ntev. Lub hnub ci xim kub, feem ntau yog 5000K-6500K, ua raws li lub hnub ci ntuj, tsim kom muaj qhov kaj, ci ntsa iab uas tshem tawm cov duab ntxoov ntxoo thiab qhov muag tsis pom kev, ua kom pom kev thoob plaws hauv chav ua haujlwm loj.
Lub zog ua haujlwm yog qhov twg T8 LED hnub ci raj tiag tiag ci. Los ntawm kev hloov mus txog 95% ntawm lub zog rau hauv lub teeb (piv rau tsuas yog 20-30% rau cov fluorescents), cov LEDs no muab kev ua haujlwm tshwj xeeb nrog kev siv hluav taws xob tsawg. A 4-ko taw T8 LED raj siv tsuas yog 18-22 watts-tsawg dua li ib nrab ntawm lub zog ntawm fluorescent sib npaug-thaum tsim lub teeb ntau dua. Rau ib lub rooj cob qhia nrog 100 qhov chaw ua haujlwm 12 teev hauv ib hnub, qhov no txhais tau tias txhua xyoo kev txuag hluav taws xob ntau dua $ 1,500 (raws li cov nqi hluav taws xob nruab nrab). Tshaj li 5-10 xyoo lifespan ntawm LEDs, cov nyiaj khaws cia sib xyaw ua ke, ua rau lawv muaj peev xwm los txo cov nuj nqis ua haujlwm.
Lub neej ntev ntawm T8 LED hnub citubes yog lwm qhov kev ua si - hloov kom zoo dua. Kev khav theeb zoo siab 50,000-60,000 teev ntawm lub neej siv tau- plaub mus rau tsib npaug ntev dua li cov raj fluorescent-LEDs txo qis zaus hloov pauv. Hauv kev cob qhia ua haujlwm 12 teev hauv ib hnub, ib lub raj LED tuaj yeem kav 7-10 xyoo ua ntej yuav tsum tau hloov. Qhov kev ua neej ntev no tshem tawm lub voj voog tsis tu ncua ntawm kev saib xyuas, kev poob qis, thiab cov nqi ua haujlwm cuam tshuam nrog cov raj fluorescent. Tsis tas li ntawd, LED systems tsis cia siab rau ballasts, tshem tawm cov kev pheej hmoo ntawm ballast tsis ua hauj lwm thiab ntxiv txo cov kev tu ncua.

Lub teeb zoo yuav ua rau muaj kev vam meej nrog T8 LED hnub ci raj, ua tsaug rau qhov siab Color Rendering Index ratings-feem ntau 80-90+-uas ua kom cov xim tshwm muaj tseeb-rau- lub neej thiab muaj zog. Qhov tseeb no yog qhov hloov pauv rau kev ua haujlwm zoo: cov neeg ua haujlwm tuaj yeem yooj yim paub qhov txawv ntawm cov khoom sib xws, kuaj xyuas qhov tsis zoo ntawm cov ntaub ntawv, thiab nyeem cov lus qhia ntxaws ntxaws, txo qhov yuam kev thiab txhim kho kev tswj hwm zoo. Cov raj LED kuj tso tawm flicker-dawb, lub teeb ntsiag to, tshem tawm qhov muag tsis pom kev thiab qaug zog los ntawm teeb pom kev zoo fluorescent. Cov kev tshawb fawb tau pom tias kev txhim kho lub teeb pom kev zoo hauv chaw ua haujlwm tuaj yeem txhawb cov neeg ua haujlwm tsim tau los ntawm 10-15% los ntawm kev ua kom pom tseeb thiab txo qhov tsis xis nyob, ua rau nws muaj txiaj ntsig zoo rau kev ua haujlwm.
Cov tswv yim zoo ntxiv ua kom cov ntaub ntawv rau T8 LEDs. Tsis zoo li cov fluorescents, uas siv sij hawm los ua kom sov thiab ua haujlwm tsis zoo nyob rau hauv qhov txias txias -ntau ntau hauv cov tsev khaws khoom tsis muaj cua sov lossis cov chaw ua haujlwm sab nraum zoov-LED cov raj teeb ci ntsa iab tam sim ntawd ntawm qhov ci, txawm tias nyob hauv sub- xoom. Qhov kev ntseeg siab no ua kom muaj kev ua tau zoo ib yam tsis hais txog ib puag ncig ib puag ncig, yuav tsum muaj rau cov chaw nyob hauv huab cua hnyav lossis hloov pauv huab cua. Tsis tas li ntawd, LEDs tsis muaj mercury lossis cov khoom siv phom sij, ua kom yooj yim pov tseg thiab ua raws li cov hom phiaj kev ruaj ntseg. Lawv cov hluav taws xob txo qis kuj tseem ua rau lub nra ntawm lub tshuab ua haujlwm txias, tsim kev txuag hluav taws xob theem nrab uas txhim kho lawv cov nqi- ua tau zoo.
Thaum T8 LED hnub ci rajmuaj tus nqi nce siab dua li cov raj fluorescent, qhov ntev - cov txiaj ntsig nyiaj txiag ua rau lawv muaj kev nqis peev zoo. A 4-foot fluorescent tube yuav raug nqi \\(5-10, piv rau \\)15-25 rau qhov sib npaug ntawm LED, tab sis qhov sib txawv thawj zaug no tau sai sai los ntawm kev txuag nyiaj. Rau lub rhiav nrog 100 fixtures ua hauj lwm 12 teev ib hnub twg, lub zog txuag nyiaj ib leeg mus rau ntau tshaj \\(1,500 ib xyoos ib zaug. Thaum factoring nyob rau hauv txo nqi txij nkawm-tsawg hloov, tsis muaj ballast kho-tag nrho cov nyiaj txuag txhua xyoo dhia mus rau \\) 2,000 los yog ntau tshaj. Qhov no txhais tau hais tias thawj zaug peev yog recouped nyob rau hauv tsawg li 6-12 lub hlis, nrog cov nyiaj khaws cia tsis tu ncua rau 7-10 xyoo lifespan ntawm LEDs. Ntau lub tseem fwv thiab cov khoom siv hluav taws xob ntxiv qab zib rau qhov kev pom zoo nrog cov nyiaj rov qab lossis kev txhawb nqa se rau kev hloov kho hluav taws xob, suav nrog 20-30% ntawm LED cov nqi yuav khoom thiab ua kom rov qab los ntawm kev nqis peev.
Kev hloov ntawm fluorescent mus rau T8 LED hnub ci raj yog ib txoj kev ncaj nraim nrog kev npaj kom raug. Pib los ntawm kev ntsuam xyuas koj qhov teeb tsa tam sim no: cov khoom muag uas twb muaj lawm, nco ntsoov lub raj ntev, thiab txheeb xyuas hom ballast (hluav taws xob lossis hlau nplaum). Qhov kev ntsuam xyuas no txiav txim siab seb koj puas xav tau "direct haum" LEDs (tshaj nrog ballasts uas twb muaj lawm) lossis "ballast bypass" LEDs, uas txuas ncaj qha mus rau lub zog hluav taws xob rau kev ua haujlwm siab tshaj plaws thiab kev ua haujlwm ntev - ballast bypass tau pom zoo rau ntev - txuag lub sij hawm, vim nws tshem tawm kev pheej hmoo ntawm ballast tsis ua haujlwm.
