Raws li LED cov ntxaij vab tshaus tau siv ntau dua, tib neeg muaj kev xav tau ntau dua rau cov khoom lag luam zoo thiab cov teeb pom kev zoo. Hauv cov txheej txheem ntim khoom, cov cuab yeej siv SMD tsoos tsis tuaj yeem ua tau raws li cov cai ntawm qee qhov xwm txheej. Raws li qhov no, qee lub tuam txhab tau hloov pauv cov ntim ntim thiab xaiv los xa COB thiab lwm yam thev naus laus zis, thaum qee lub tuam txhab tau xaiv los txhim kho SMD thev naus laus zis. Ntawm lawv, GOB thev naus laus zis yog ib qho kev siv thev naus laus zis tom qab kev txhim kho ntawm SMD ntim txheej txheem.
Yog li, nrog GOB thev naus laus zis, LED cov khoom lag luam puas tuaj yeem ua tiav daim ntawv thov dav dua? Yuav ua li cas rau yav tom ntej kev lag luam kev loj hlob ntawm GOB qhia? Cia peb saib!
Txij li thaum txoj kev loj hlob ntawm LED zaub kev lag luam, suav nrog COB zaub, ntau yam kev tsim khoom thiab ntim cov txheej txheem tau tshwm sim ib tom qab, los ntawm cov txheej txheem yav dhau los ncaj nraim (DIP), mus rau saum npoo (SMD) txheej txheem, mus rau qhov tshwm sim ntawm COB. ntim tshuab, thiab thaum kawg mus rau qhov tshwm sim ntawm GOB ntim tshuab.
⚪ COB ntim tshuab yog dab tsi?
COB ntim txhais tau hais tias nws ncaj qha ua cov nti rau hauv PCB substrate los ua kev sib txuas hluav taws xob. Nws lub hom phiaj tseem ceeb yog los daws qhov teeb meem kub dissipation ntawm LED cov ntxaij vab tshaus. Piv nrog rau cov plug-in ncaj qha thiab SMD, nws cov yam ntxwv yog qhov chaw txuag, kev ua haujlwm yooj yim ntim, thiab kev tswj xyuas thermal zoo. Tam sim no, COB ntim feem ntau yog siv hauv qee cov khoom me me.
Dab tsi yog qhov zoo ntawm COB ntim tshuab?
1. Ultra-lub teeb thiab nyias: Raws li qhov xav tau tiag tiag ntawm cov neeg siv khoom, PCB boards nrog lub thickness ntawm 0.4-1.2mm tuaj yeem siv los txo qhov hnyav kom tsawg kawg yog 1/3 ntawm cov khoom qub, uas tuaj yeem txo qhov hnyav. tus qauv, kev thauj mus los thiab engineering nqi rau cov neeg siv khoom.
2. Kev tiv thaiv kev sib tsoo thiab kev ua haujlwm siab: COB cov khoom ncaj qha encapsulate LED nti nyob rau hauv concave txoj hauj lwm ntawm PCB board, thiab ces siv epoxy resin kua nplaum rau encapsulate thiab kho. Qhov saum npoo ntawm lub teeb taw tes yog tsa rau hauv ib qho chaw tsa, uas yog du thiab tawv, tiv taus kev sib tsoo thiab hnav.
3. Loj saib lub kaum ntse ntse: COB ntim siv ntiav ntiav zoo kheej kheej lub teeb emission, nrog rau lub kaum sab xis saib ntau dua 175 degrees, ze rau 180 degrees, thiab muaj cov nyhuv zoo dua optical diffuse xim.
4. Muaj peev xwm ua kom muaj cua sov muaj zog: COB cov khoom ntim lub teeb ntawm lub rooj tsavxwm PCB, thiab hloov cov cua sov ntawm cov wick sai sai los ntawm cov ntawv ci tooj liab ntawm PCB board. Tsis tas li ntawd, cov tuab ntawm cov ntawv ci tooj liab ntawm PCB pawg thawj coj saib muaj cov txheej txheem nruj heev, thiab cov txheej txheem kub kub yuav tsis ua rau lub teeb hnyav heev. Yog li ntawd, muaj ob peb lub teeb tuag, uas ua rau lub neej ntawm lub teeb zoo heev.
5. Hnav-tiv taus thiab yooj yim los ntxuav: Qhov saum npoo ntawm lub teeb taw tes yog convex rau hauv ib qho chaw kheej kheej, uas yog du thiab tawv, tiv taus kev sib tsoo thiab hnav; yog tias muaj qhov tsis zoo, nws tuaj yeem kho qhov taw tes ntawm taw tes; tsis muaj daim npog qhov ncauj, plua plav tuaj yeem ntxuav nrog dej lossis ntaub.
6. Tag nrho cov huab cua zoo heev: Nws txais kev kho mob triple tiv thaiv, nrog rau cov dej tsis zoo, noo noo, corrosion, plua plav, hluav taws xob zoo li qub, oxidation, thiab ultraviolet; Nws ua tau raws li tag nrho cov huab cua ua haujlwm thiab tseem tuaj yeem siv tau ib txwm nyob rau hauv qhov kub thiab txias qhov sib txawv ntawm rho tawm 30 degrees rau ntxiv rau 80 degrees.
⚪GOB ntim tshuab yog dab tsi?
GOB ntim yog lub tshuab ntim khoom tsim los daws cov teeb meem kev tiv thaiv ntawm LED teeb hlaws. Nws siv cov ntaub ntawv pob tshab siab heev los encapsulate PCB substrate thiab LED ntim tsev los tsim kev tiv thaiv zoo. Nws yog sib npaug rau kev ntxiv ib txheej ntawm kev tiv thaiv nyob rau hauv pem hauv ntej ntawm thawj LED module, yog li ua tiav kev tiv thaiv kev ua haujlwm siab thiab ua tiav kaum kev tiv thaiv nrog rau cov dej tsis zoo, noo noo-pov thawj, cuam tshuam-pov thawj, bump-proof, anti-static, ntsev tsuag pov thawj. , anti-oxidation, anti-xiav lub teeb, thiab tiv thaiv kev vibration.
Dab tsi yog qhov zoo ntawm GOB ntim tshuab?
1. GOB txheej txheem zoo: Nws yog ib qho kev tiv thaiv zoo heev LED zaub screen uas tuaj yeem ua tiav yim kev tiv thaiv: tsis muaj dej, noo noo-pov thawj, tiv thaiv kev sib tsoo, plua plav pov thawj, tiv thaiv xeb, tiv thaiv xiav lub teeb, tiv thaiv ntsev, thiab tiv thaiv. zoo li qub. Thiab nws yuav tsis muaj teeb meem cuam tshuam rau cov cua sov dissipation thiab brightness poob. Kev soj ntsuam ntev ntev tau pom tias cov kua nplaum tiv thaiv txawm tias yuav pab kom cov cua sov dissipate, txo tus nqi necrosis ntawm cov hlaws dai, thiab ua rau lub vijtsam ruaj khov, yog li txuas ntxiv lub neej kev pab cuam.
2. Los ntawm GOB txheej txheem ua, cov granular pixels nyob rau saum npoo ntawm lub thawj lub teeb lub rooj tsavxwm tau hloov mus rau hauv ib tug zuag qhia tag nrho lub teeb lub teeb board, realizing lub transformation ntawm taw tes lub teeb qhov chaw mus rau qhov chaw lub teeb. Cov khoom emits lub teeb ntau tusyees, cov nyhuv tso saib yog pom tseeb thiab ntau pob tshab, thiab cov khoom saib lub kaum sab xis zoo heev (ob kab rov tav thiab ntsug tuaj yeem ncav cuag ze li ntawm 180 °), tshem tawm moiré, txhim kho cov khoom zoo sib xws, txo qis glare thiab glare. , thiab txo qhov pom kev qaug zog.
⚪Qhov txawv ntawm COB thiab GOB yog dab tsi?
Qhov sib txawv ntawm COB thiab GOB feem ntau yog nyob rau hauv tus txheej txheem. Txawm hais tias lub pob COB muaj lub tiaj tiaj thiab muaj kev tiv thaiv zoo dua li cov pob SMD ib txwm, GOB pob ntxiv cov txheej txheem ua kua nplaum rau ntawm qhov screen, uas ua rau cov hlaws LED teeb ntau ruaj khov, zoo heev txo qhov muaj peev xwm poob, thiab muaj zog stability.
⚪Qhov twg muaj qhov zoo, COB lossis GOB?
Tsis muaj cov qauv uas zoo dua, COB lossis GOB, vim tias muaj ntau yam los txiav txim seb cov txheej txheem ntim khoom puas zoo lossis tsis zoo. Qhov tseem ceeb yog saib seb peb muaj nuj nqis li cas, seb nws yog qhov ua tau zoo ntawm LED teeb hlaws lossis kev tiv thaiv, yog li txhua lub tshuab ntim khoom muaj nws qhov zoo thiab tsis tuaj yeem ua kom dav dav.
Thaum peb xaiv tiag tiag, seb puas yuav siv COB ntim lossis GOB ntim yuav tsum tau txiav txim siab ua ke nrog cov ntsiab lus zoo xws li peb tus kheej qhov chaw teeb tsa thiab lub sijhawm ua haujlwm, thiab qhov no kuj tseem cuam tshuam txog kev tswj tus nqi thiab cov txiaj ntsig.
