COB LED zaub yog dab tsi?
COB LED zaub sawv rau "Chip-on-Board Light Emitting Diode" zaub. Nws yog ib hom LED thev naus laus zis uas ntau lub chips LED tau txuas ncaj qha mus rau hauv lub substrate los tsim ib qho module lossis array. Hauv COB LED zaub, ib tus neeg LED chips tau ntim nruj ua ke thiab npog nrog phosphor txheej uas emits lub teeb nyob rau hauv ntau yam xim.
COB technology yog dab tsi?
COB thev naus laus zis, uas sawv cev rau "chip-on-board," yog ib txoj hauv kev ntawm encapsulating semiconductor li uas muaj ntau yam sib xyaw ua ke chips tau txuas ncaj qha rau ntawm lub substrate lossis Circuit Court board. Cov chips no feem ntau yog nruj nreem ntim ua ke thiab encapsulated nrog tiv thaiv resins lossis epoxy resins. Hauv COB thev naus laus zis, ib tus neeg semiconductor chips feem ntau sib txuas ncaj qha rau lub substrate siv lead ua bonding los yog flip chip bonding cov tswv yim. Qhov kev sib txuas ncaj qha no tshem tawm qhov xav tau rau cov khoom ntim ntim nrog cov tsev nyob sib cais.
Nyob rau hauv xyoo tas los no, COB (Chip-on-Board) thev naus laus zis tau pom ntau qhov kev nce qib thiab kev tsim kho tshiab, uas tau tsav los ntawm kev thov rau cov khoom siv hluav taws xob me me, ua haujlwm zoo dua, thiab ua haujlwm siab dua.
SMD vs COB Ntim Technology
| COB | SMD | |
| Kev sib xyaw ntom ntom | Siab dua, tso cai rau ntau LED chips ntawm lub substrate | qis dua, nrog ib tus neeg LED chips mounted ntawm PCB |
| Thaum tshav kub kub Dissipation | Cov cua kub zoo dua vim kev sib txuas ncaj qha ntawm LED chips | Tsawg tshav kub dissipation vim tus kheej encapsulation |
| Kev ntseeg tau | Txhim kho kev ntseeg siab nrog tsawg cov ntsiab lus ntawm kev ua tsis tiav | Cov chips LED tus kheej tej zaum yuav ua rau tsis ua hauj lwm ntau dua |
| Tsim Flexibility | Txwv tsis pub muaj kev hloov pauv hauv kev ua tiav cov duab kev cai | Ntau qhov yooj yim rau cov qauv nkhaus lossis tsis sib xws |
1. Muab piv rau SMD thev naus laus zis, COB thev naus laus zis tso cai rau qib siab ntawm kev sib koom ua ke los ntawm kev sib koom ua ke ntawm LED nti ncaj qha mus rau substrate. Qhov kev ceev dua no ua rau cov lus pom nrog ntau dua qhov ci ntsa iab thiab kev tswj xyuas thermal zoo dua. Nrog COB, cov chips LED yog sib txuas ncaj qha mus rau lub substrate, uas ua kom yooj yim dua cov cua sov dissipation. Qhov no txhais tau hais tias kev ntseeg siab thiab lub neej ntawm COB cov lus qhia tau zoo dua qub, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov ci ntsa iab uas qhov kev tswj xyuas thermal yog qhov tseem ceeb.
2. Vim lawv txoj kev tsim kho, COB LEDs muaj kev ntseeg siab ntau dua li SMD LEDs. COB muaj cov ntsiab lus tsawg dua ntawm kev ua tsis tau zoo dua li SMD, qhov twg txhua qhov LED nti yog ib tus zuj zus encapsulated. Kev sib txuas ncaj qha ntawm LED chips hauv COB thev naus laus zis tshem tawm cov khoom siv encapsulation hauv SMD LEDs, txo qhov kev pheej hmoo ntawm degradation dhau sijhawm. Raws li qhov tshwm sim, COB cov lus pom muaj tsawg dua ib tus neeg LED tsis ua haujlwm thiab muaj kev ntseeg siab ntau dua rau kev ua haujlwm tsis tu ncua hauv ib puag ncig hnyav.
3. COB thev naus laus zis muab cov nqi zoo dua SMD thev naus laus zis, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov kev ci ntsa iab. Los ntawm kev tshem tawm qhov xav tau ntawm ib tus neeg ntim khoom thiab txo qis kev tsim khoom nyuaj, COB cov lus pom muaj txiaj ntsig zoo dua los tsim. Cov txheej txheem sib txuas ncaj qha hauv COB thev naus laus zis ua kom yooj yim rau kev tsim khoom thiab txo cov khoom siv, yog li txo qis tag nrho cov nqi tsim khoom.
4. Ntxiv mus, nrog nws superior waterproof, dustproof thiab anti-kev sib tsoo kev ua tau zoo,COB LED zaubtuaj yeem siv tau ruaj khov thiab ruaj khov hauv ntau qhov chaw hnyav.
Qhov tsis zoo ntawm COB LED zaub
Tau kawg peb yuav tsum tham txog qhov tsis zoo ntawm COB cov ntxaij vab tshaus thiab.
· Tus Nqi Tu: Vim yog kev tsim kho tshwj xeeb ntawm COB LED cov lus, lawv cov kev saib xyuas yuav xav tau kev paub tshwj xeeb lossis kev cob qhia. Tsis zoo li SMD cov lus qhia qhov twg ib tus neeg LED modules tuaj yeem hloov tau yooj yim, COB cov lus qhia feem ntau xav tau cov cuab yeej tshwj xeeb thiab kev txawj ntse los kho, uas tuaj yeem ua rau lub sijhawm ua haujlwm ntev thaum kho lossis kho.
· Complexity ntawm Customization: Piv rau lwm cov khoom siv yees duab, COB LED zaub tuaj yeem nthuav qhia qee qhov teeb meem thaum nws los txog rau kev kho. Ua kom tiav cov kev cai tsim tshwj xeeb lossis cov kev teeb tsa tshwj xeeb yuav xav tau kev ua haujlwm engineering ntxiv lossis kev hloov kho, uas tuaj yeem ua rau ncua sijhawm me ntsis lossis nce nqi.
