LED zaub tau hloov pauv txoj hauv kev uas peb nthuav qhia cov ntaub ntawv, ob qho tib si hauv chaw sab hauv thiab sab nraum zoov. Ob hom LED thev naus laus zis ua lag luam tseem ceeb: SMD (Nto-Mounted Device) LED thiab DIP (Dual In-line Package) LED. Txhua tus muaj cov yam ntxwv tshwj xeeb, thiab paub txog lawv qhov sib txawv yog qhov tseem ceeb rau kev xaiv txoj cai nyob ntawm koj daim ntawv thov. Cia peb rhuav tshem ob hom LED no thiab tshawb xyuas seb lawv txawv li cas ntawm cov qauv, kev ua haujlwm, thiab kev siv.
1. LED Structure
Qhov tseem ceeb sib txawv ntawm SMD thiab DIP LEDs nyob hauv lawv lub cev qauv:
SMD LED Zaub: Nyob rau hauv ib qho SMD zaub, LED chips yog mounted ncaj qha mus rau saum npoo ntawm ib tug luam Circuit Court board (PCB). Ib qho SMD LED feem ntau muaj xim liab, ntsuab, thiab xiav diodes hauv ib pob, tsim ib pixel.
DIP LED Zaub: DIP LEDs muaj cais liab, ntsuab, thiab xiav diodes nyob rau hauv lub plhaub tawv tawv. Cov LEDs no tau teeb tsa los ntawm qhov hauv PCB, thiab txhua lub diode ua ib feem ntawm pixel loj.
2. Pixel Tsim thiab ntom
Kev teeb tsa ntawm LEDs cuam tshuam rau pixel ceev thiab cov duab pom tseeb ntawm ob hom:
SMD: Vim tias tag nrho peb lub diodes (RGB) muaj nyob rau hauv ib pob me me, SMD LEDs tso cai rau ntau pixel ceev. Qhov no ua rau lawv zoo tagnrho rau cov kev daws teeb meem siab uas yuav tsum muaj cov ntsiab lus zoo thiab cov duab ntse.
DIP: Txhua xim diode yog muab tso rau nyias, uas txwv qhov pixel ceev, tshwj xeeb tshaj yog nyob rau hauv me me pitch qhia. Yog li ntawd, DIP LEDs feem ntau yog siv rau hauv cov ntawv thov uas qhov kev daws teeb meem siab tsis yog qhov tseem ceeb tshaj plaws, xws li cov ntxaij vab tshaus loj loj.
3. Kev ci ntsa iab
Brightness yog lwm qhov tseem ceeb thaum xaiv ntawm SMD thiab DIP LED zaub:
SMD: SMD LEDs muaj qhov ci nruab nrab, feem ntau haum rau qhov chaw sab hauv tsev lossis sab nraum zoov. Lawv qhov zoo tshaj plaws yog kev sib xyaw xim zoo dua thiab cov duab zoo, tsis yog qhov ci ntsa iab.
DIP: DIP LEDs paub txog lawv qhov ci ntsa iab, ua rau lawv zoo tagnrho rau kev siv sab nraum zoov. Lawv tuaj yeem tswj tau qhov pom tseeb ntawm lub hnub ncaj qha, uas yog ib qho ntawm lawv qhov zoo tshaj plaws ntawm SMD thev naus laus zis.
4. Saib lub kaum sab xis
Saib lub kaum sab xis hais txog qhov deb ntawm qhov nruab nrab koj tuaj yeem saib cov duab yam tsis poob duab zoo:
SMD: SMD LEDs muab lub kaum sab xis pom dav dua, feem ntau mus txog 160 degrees kab rov tav thiab ntsug. Qhov no ua rau lawv muaj kev xaiv nrov rau sab hauv tsev, qhov twg cov neeg tuaj saib saib cov ntxaij vab tshaus los ntawm ntau lub kaum ntse ntse.
DIP: DIP LEDs feem ntau pom lub kaum ntse ntse, feem ntau nyob ib ncig ntawm 100 txog 110 degrees. Thaum qhov no yog qhov tsim nyog rau qhov chaw sab nraum zoov uas cov neeg saib feem ntau nyob deb, nws tsis zoo rau kev pom ze lossis off-angle.
5. Durability thiab huab cua tsis kam
Durability yog qhov tseem ceeb, tshwj xeeb tshaj yog rau cov khoom siv sab nraum zoov uas ntsib cov huab cua nyuaj:
SMD: Thaum SMD LEDs haum rau ntau qhov siv sab nraum zoov, lawv tsis tshua muaj zog dua DIP LEDs hauv huab cua huab cua. Lawv cov qauv tsim saum npoo ua rau lawv me ntsis yooj yim rau kev puas tsuaj los ntawm kev ya raws, cua sov, lossis cuam tshuam.
DIP: DIP LEDs feem ntau siv tau ntev dua thiab muaj kev tiv thaiv huab cua zoo dua. Lawv cov ntaub thaiv npog tiv thaiv pab lawv tiv taus nag, plua plav, thiab kub kub, ua rau lawv xaiv rau kev teeb tsa sab nraum zoov loj xws li cov ntawv tshaj tawm.
6. Kev Siv Hluav Taws Xob
Kev siv hluav taws xob tuaj yeem ua rau muaj kev txhawj xeeb rau lub sijhawm ntev lossis kev teeb tsa loj:
SMD: SMD cov lus pom muaj zog ntau dua li DIP cov lus vim lawv cov qauv tsim thiab kev cog lus loj. Lawv xav tau lub zog tsawg dua los tsim cov xim zoo nkauj thiab cov duab ntxaws, ua rau lawv xaiv zoo rau cov haujlwm uas xav tau lub zog.
DIP: DIP qhia siv ntau lub zog kom ua tiav lawv cov qib siab ci ntsa iab. Qhov kev thov kom muaj zog ntxiv no tuaj yeem ua rau cov nqi ua haujlwm siab dua, tshwj xeeb tshaj yog rau kev teeb tsa sab nraum zoov uas khiav tsis tu ncua.
7. Tus nqi
Cov peev nyiaj ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab ntawm SMD thiab DIP LED zaub:
SMD: Feem ntau, SMD cov khoom siv kim dua vim lawv qhov kev daws teeb meem siab thiab cov txheej txheem tsim khoom ntau dua. Txawm li cas los xij, lawv qhov kev ua tau zoo ntawm cov xim raug thiab pixel ntom ua rau tus nqi rau ntau daim ntawv thov.
DIP: DIP cov lus qhia feem ntau pheej yig dua, tshwj xeeb tshaj yog rau qhov loj dua, kev daws teeb meem sab nraum zoov. Tus nqi qis ua rau lawv muaj kev xaiv nrov rau cov haujlwm uas yuav tsum tau ua kom ruaj khov tab sis tsis tas yuav nthuav dav zoo.
8. Kev siv ntau
Hom LED zaub koj xaiv yuav nyob ntawm ntau yam ntawm daim ntawv thov npaj:
SMD: SMD LEDs tau dav siv rau sab hauv tsev, nrog rau cov chav sib tham, khw muag khoom kos npe, cov khoom pov thawj kev lag luam, thiab TV studios. Lawv kuj pom muaj nyob rau hauv me me rau sab nraum zoov qhov chaw siab yog qhov tseem ceeb, xws li cov ntxaij vab tshaus tshaj tawm.
DIP: DIP LEDs dominates loj sab nraum zoov installation, xws li billboards, chaw ntau pob cov ntxaij vab tshaus, thiab sab nraum zoov kev tshwm sim. Lawv cov qauv tsim muaj zog thiab ci ntsa iab ua rau lawv zoo meej rau qhov chaw uas huab cua tsis zoo thiab lub hnub ci pom kev xav tau.
Xaus: Xaiv ntawm SMD thiab DIP LED Zaub
Thaum xaiv ntawm SMD thiab DIP LED zaub, nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev cai tshwj xeeb ntawm koj qhov project. Yog tias koj xav tau kev daws teeb meem siab, pom dav dav, thiab cov duab zoo dua, tshwj xeeb tshaj yog rau kev teeb tsa sab hauv tsev, SMD LED zaub yog txoj hauv kev mus. Ntawm qhov tod tes, rau kev teeb tsa sab nraum zoov loj qhov chaw ci ntsa iab, ua haujlwm ntev, thiab kev siv nyiaj txiag yog qhov tseem ceeb, DIP LED zaub feem ntau yog qhov kev xaiv zoo dua.
