Thaum nws los txog rau kev txhim kho koj lub teeb pom kev zoo rau lub zog siv hluav taws xob ntau dua thiab siv tau ntev dua LED thev naus laus zis, ib lo lus nug feem ntau yog seb koj puas tuaj yeem hloov cov raj fluorescent nrog LED yam tsis tau tshem lub ballast. Cov lus teb yog yog, hauv qee kis.
Ua ntej tshaj plaws, nws yog ib qho tseem ceeb kom nkag siab tias lub ballast yog dab tsi thiab nws ua dab tsi. Lub ballast yog ib qho khoom siv hluav taws xob uas tswj cov hluav taws xob thiab cov khoom siv tam sim no rau lub teeb, txhawm rau pib thiab ua haujlwm kom zoo. Nws yog feem ntau siv nyob rau hauv cov teeb fluorescent, nrog rau lwm yam teeb pom kev zoo xws li HID thiab neon. Yog tsis muaj ballast, lub teeb yuav tsis pib, los yog yuav flicker, hum, los yog hlawv tawm ntxov ntxov.
Tam sim no, LED teeb ua haujlwm txawv dua li cov teeb fluorescent, thiab lawv tsis tas yuav muaj lub ballast ua haujlwm. Qhov tseeb, siv lub ballast nrog LED tuaj yeem ua rau muaj teeb meem xws li kev txo qis, kev ua neej luv luv, thiab teeb meem kev sib raug zoo. Yog li ntawd, qhov kev daws teeb meem zoo tshaj plaws yuav yog tshem tawm cov ballast ntawm lub teeb thiab txuas lub teeb LED ncaj qha mus rau kab hluav taws xob.
Txawm li cas los xij, qhov no yuav tsis yog qhov ua tau zoo lossis ua tau. Qee qhov xwm txheej uas koj xav khaws cov ballast suav nrog:
- Cov kab hluav taws xob uas twb muaj lawm yog qhov nyuaj lossis kim dua los hloov dua tshiab
- Lub fixture muaj kev cai los yog tshwj xeeb tsim uas yuav tsum tau ib tug ballast
- Lub ballast tsis yooj yim rau kev nkag los yog tshem tawm
- Tus nqi txuag los ntawm kev tsis hloov lub ballast yog siab dua qhov muaj peev xwm tsis zoo
Hauv cov xwm txheej no, koj tseem tuaj yeem siv LED teeb uas tsim los ua haujlwm nrog ballasts sib xws. Cov no yog hu ua ballast-compatible, ballast-driven, los yog plug-and-play LED teeb. Lawv raug tsim los ua haujlwm nrog cov ballast uas twb muaj lawm, tsis tas yuav hloov kho lossis rov ua dua tshiab. Txhua yam koj yuav tsum ua yog tsuas yog hloov lub raj fluorescent nrog lub raj LED, thiab nws yuav ua haujlwm zoo li ntxim nyiam.
Muaj ob peb yam uas yuav tsum tau xav txog thaum xaiv txoj cai ballast-tshaj LED raj rau koj lub fixture. Cov no suav nrog hom ballast (hluav taws xob lossis sib nqus), qhov ntsuas hluav taws xob thiab wattage, xim kub thiab ci ntsa iab, thiab kev sib raug zoo nrog dimming lossis hloov. Nws yog ib lub tswv yim zoo los sab laj nrog ib tus kws paub txog teeb pom kev zoo lossis tus neeg muag khoom kom paub meej tias koj xaiv txoj cai LED raj rau koj cov kev xav tau tshwj xeeb.
Hauv kev xaus, thaum nws tuaj yeem hloov cov raj fluorescent nrog LED yam tsis tau tshem cov ballast, nws tsis yog qhov kev xaiv zoo tshaj plaws. Yog tias koj tuaj yeem tshem tawm cov ballast thiab txuas cov LED ncaj qha rau cov kab hluav taws xob, koj yuav ua tiav cov txiaj ntsig zoo dua ntawm kev ua haujlwm, kev ua haujlwm ntev, thiab kev sib raug zoo. Tab sis yog tias koj xav tau kom lub ballast nyob rau hauv qhov chaw, nco ntsoov xaiv ballast-tshaj LED raj uas tsim los ua haujlwm seamlessly nrog nws.
