Direct Hlau Tubes
Direct hlau raj yog nyob deb ntawm qhov ncaj tshaj plaws, nyob rau hauv hais tias lawv bypass lub ballast kiag li thiab khiav ncaj qha tawm ntawm kab voltage. Tsis xav tau lub ballast muaj qhov txiaj ntsig tseem ceeb hauv kev txuag nqi thoob plaws hauv lub neej kev sib tw, vim tsis muaj qhov yuav tsum tau hloov cov ballasts kim uas tsis tu ncua lossis hnav tawm. Qhov no tiag tiag los rau hauv kev ua si nrog cov kev teeb tsa loj xws li cov tsev khaws khoom thiab cov tsev ua haujlwm ntau zaj dab neeg, vim tias kev txuag nqi ib qho khoom siv tuaj yeem ntxiv tau sai nrog ntau cov khoom siv.
Ib yam dab tsi uas yuav tsum nco ntsoov nrog cov khoom siv hluav taws xob ncaj qha yog tias lawv yuav xav tau qee qhov ntxiv los ua kom tiav retrofitting. Tube teeb siv "tombstone" sockets rau lub hwj chim thiab tuav lub teeb, thiab muaj ob lub ntsiab tombstones siv nyob rau hauv kev lag luam teeb pom kev zoo - Shunted thiab Non-Shunted. Rau cov khoom siv hluav taws xob ncaj qha, tsis yog shunted sai pib tombstones yuav tsum tau ua haujlwm kom raug. Yog hais tias lub fixture uas twb muaj lawm yog ib hom T12, ces nws yuav tsum twb muaj qhov tseeb tombstone hom twb ntsia.
Txawm li cas los xij, yog tias nws yog T8 hom fixture, ces cov tswv yim tombstone sockets yuav tsum tau hloov mus rau Non-Shunted Rapid Start T12 style sockets thiaj li ua haujlwm zoo. Qhov no yog vim lub voj voog sib txuas hauv T8 qhov (sockets) uas tsis tso cai rau lawv cais cov kab lossis cov kab hluav taws xob tsis zoo. Txawm hais tias qhov no yog cov txheej txheem yooj yim zoo nkauj, nws raug pom zoo tias tus kws tshaj lij hluav taws xob tsim nyog thiab muaj ntawv tso cai ua tiav txoj haujlwm no vim nws muaj qee qhov kev rov ua dua tshiab. Rau cov khoom lag luam, yuav tsum siv cov tombstones kom raug.
Electronic Ballast Compatible Tubes
Feem ntau hu ua "Type-A" lossis "Plug-n-Play" tubes, hluav taws xob ballast tau tshaj cov raj yog ib qho tshiab ntxiv rau lub lag luam teeb pom kev zoo. Raws li tau hais los ntawm lub npe, cov teeb no yog tsim los ua haujlwm nrog cov khoom siv hluav taws xob uas twb muaj lawm uas muaj cov khoom siv hluav taws xob. Vim li no, cov teeb no yuav tsis ua haujlwm yog tias tau teeb tsa hauv cov khoom siv uas muaj cov sib nqus ballasts lossis tsis muaj ballast txhua. Vim tias tiam kawg ntawm cov khoom siv fluorescent tsuas yog siv cov khoom siv hluav taws xob xwb, cov raj no tau dhau los ua ib qho ntawm cov khoom muag muag uas ua haujlwm nrog cov khoom siv uas twb muaj lawm, thiab yuav muaj kev vam meej ntxiv vim tias cov khoom siv uas twb muaj lawm txuas ntxiv mus nrog LED thev naus laus zis.
Cov qij no yog qhov yooj yim rau nruab raws li lawv tsuas yog xav tau hloov lub qub fluorescent raj nrog lub raj LED tshiab. Vim tias muaj ntau ntau cov khoom siv hluav taws xob sib txawv ntawm kev ua lag luam, LED tube tuam ntxhab tau dhau los ntawm kev sim ntau yam kom ntseeg tau tias lawv cov khoom siv hluav taws xob sib txuas yuav ua haujlwm tsis hais lub chaw tsim khoom ballast. Qhov no coj tawm qhov kev kwv yees rau cov neeg yuav khoom thiab ua rau kev teeb tsa yooj yim li sai tau.
Thaum qhov no yog qhov zoo los ntawm qhov yooj yim ntawm kev siv, nws feem ntau ua rau cov hlab no muaj tus nqi pib dua. Nyob rau sab saum toj ntawm qhov no, yog tias lub ballast tsis ua haujlwm ces lub raj yuav tsis teeb pom kev ntxiv uas ntxiv rau cov nqi mus sij hawm ntev ntawm hom LED teeb teeb pom kev zoo no. Vim li no, ballast tau tshaj cov raj feem ntau tsuas yog ntsia rau ntawm daim ntawv thov me me uas yooj yim ntawm kev teeb tsa yog qhov tseem ceeb thiab tus naj npawb ntawm cov ballasts uas muaj zog rau cov raj tsis tuaj yeem muaj kev pheej hmoo nyiaj txiag ntau.
