Thaum nws los txog rau LED thev naus laus zis, muaj ntau yam ntawm SMD (Surface Mount Device) kev xaiv muaj rau cov neeg tsim khoom xaiv. Ob hom SMD feem ntau yog 2835 thiab 3030. Tab sis dab tsi yog qhov txawv ntawm ob hom SMD LEDs thiab qhov twg yog qhov zoo dua rau koj daim ntawv thov?
Ua ntej, cia peb saib ntawm 2835. Qhov no SMD LED feem ntau suav hais tias yog ib qho ntawm cov kev xaiv nrov tshaj plaws thiab siv dav hauv khw. Nws yog qhov me me piv rau lwm hom SMD thiab muaj qhov ntev ntawm 2.8 hli x 3.5 hli. Nws tsim ib ncig ntawm 20-28 lumens ntawm lub teeb tso zis thiab feem ntau yog siv nyob rau hauv ntau yam kev siv teeb pom kev zoo, xws li LED tubes, vaj huam sib luag teeb, thiab downlights.
Hauv qhov sib piv, SMD 3030 LED yog qhov kev xaiv loj dua ntsuas 3.0 mm x 3.0 mm. Nws muaj lub teeb tso zis ntau dua, tsim ib puag ncig 30-40 lumens, ua rau nws yog qhov kev xaiv zoo rau cov ntawv thov uas yuav tsum muaj qhov ci ntsa iab. Vim nws qhov loj dua, nws kuj muaj cov cua kub zoo dua, uas yog qhov tseem ceeb tshwj xeeb rau cov ntawv thov uas qhov kub siab yuav yog qhov teeb meem.
Lwm qhov sib txawv ntawm ob hom LED yog tus naj npawb ntawm LED chips ntawm txhua pob. Lub 2835 feem ntau tsuas muaj ib nti xwb, thaum lub 3030 feem ntau muaj ob lub chips, txawm hais tias qee lub tuam txhab kuj tseem tuaj yeem muab 3030 pob nrog plaub chips.
Thaum nws los txog rau tag nrho cov kev ua tau zoo, SMD 3030 feem ntau muaj kev ua haujlwm siab dua piv rau 2835. Qhov no yog vim nws qhov loj dua thiab ntau lub chips, uas tso cai rau nws tawm ntau lub teeb thaum siv lub zog tsawg. Txawm li cas los xij, nws tseem ceeb heev uas yuav tsum nco ntsoov tias qhov kev ua tau zoo tag nrho yuav nyob ntawm seb cov txheej txheem tsim khoom tshwj xeeb thiab cov khoom siv.
Yog li, qhov twg koj yuav tsum xaiv rau koj daim ntawv thov? Thaum kawg, nws yuav nyob ntawm ntau yam, suav nrog cov teeb pom kev uas xav tau, qhov loj me, thiab cov kev xav tau ntawm cov cua sov. Yog tias koj tab tom nrhiav kev xaiv me me rau cov ntawv thov xws li lub teeb vaj huam sib luag thiab cov raj LED, SMD 2835 tuaj yeem yog qhov kev xaiv zoo. Txawm li cas los xij, yog tias koj xav tau qhov tso zis ntau dua thiab muaj cua sov zoo dua, SMD 3030 yuav yog qhov kev xaiv zoo dua.
Hauv kev xaus, ob qho tib si SMD 2835 thiab SMD 3030 muaj qhov tshwj xeeb zoo nyob ntawm koj cov kev xav tau tshwj xeeb. Kev nkag siab txog qhov sib txawv no tuaj yeem pab koj txiav txim siab thaum xaiv qhov zoo LED rau koj daim ntawv thov.
