Nrog kev txhim kho sai ntawm cov cuab yeej siv thev naus laus zis, cov khoom ntim ntim khoom COB tau dhau los ua qhov chaw kub nyob hauv nruab nrab-rau-qib-kawg zaub lag luam thiab dhau los ua kev txhim kho ntawm cov ntxaij vab tshaus yav tom ntej. COB yog dab tsi? Niaj hnub no, cia tus kws tshaj tawm qhia ntxaws:
1. LED zaub thev naus laus zis
Tam sim no, muaj ob daim ntawv tseem ceeb ntawm me me-suab puv xim LED zaub ntim tshuab, ib qho yog cov khoom ntim ntu SMD thev naus laus zis, uas siv COB thev naus laus zis los ua ke ntim. Qhov saum npoo tau qhia txog nees nkaum xyoo dhau los. Los ntawm passive mus rau cov khoom siv sib xyaw thiab cov khoom siv sib txuas ua ke, nws thiaj li dhau los ua ib qho chaw tiv thaiv saum npoo av (COB) thiab tuaj yeem sib sau ua ke los ntawm cov cuab yeej tuaj tos thiab tso khoom. COB yog daim ntawv thov loj hauv kev ntim khoom tshiab rau cov xim puv xim LED tsuas yog nyob rau xyoo tas los no.
SMD ntim tshuab
SMD: yog lub npe luv ntawm cov khoom siv saum npoo av, uas txhais tau tias yog cov khoom siv saum npoo av. Nws yog ib qho ntawm SMT (Surface Mount Technology) cov khoom siv. Tam sim no, sab hauv tsev puv xim LED qhia siv peb-hauv-ib sab saum toj-teeb SMD, uas hais txog SMT teeb ntim nrog peb xim sib txawv ntawm RGB LED chips, raws li qee qhov kev deb Encapsulation hauv tib lub gel los tsim lub ntim technology ntawm cov zaub module.
Cov txheej txheem tseem ceeb yog txhawm rau txhawm rau txhawm rau txhawm rau teeb tsa lub teeb ci LED (SMD nto teeb), thiab tom qab ntawd muab lo rau ntawm PCB pawg thawj coj los ntawm cov laug. Tom qab ntawd muab tso rau saum npoo thiab PCB pawg thawj coj saib hauv qhov cub kub kom sov thiab ua kom zoo (rov ua kom zoo dua qub), thiab tom qab ntawd muab cov LED coj los ntawm cov txheej txheem ua kom hnyav, tom qab ntawd muab cov nplaum txuas nrog epoxy cob, thiab thaum kawg tsim cov qauv duab, thiab tom qab ntawv txuas qhov module rau chav nruab nrab.
Cov khoom tseem ceeb ntawm txheej txheem SMD:
Sawv ntsug: Kev txhawb nqa thiab ua kom sov sov, cov khoom txhawb nqa yog electroplated los ua ntau yam, sab hauv sab nraud yog cov khoom siv, tooj liab, npib tsib xee, tooj liab, nyiaj, tsib txheej.
LED nti: Cov nti yog lub hauv paus tseem ceeb ntawm lub teeb ci LED thiab yog cov khoom siv hluav taws xob tso tawm hluav taws xob.
Cov khoom siv hluav taws xob: PAD nti txuas (PAD) thiab bracket, thiab tuaj yeem hloov tau.
Epoxy resin: tiv thaiv cov qauv sab hauv ntawm cov hlaws teeb, thiab tuaj yeem hloov xim, ci thiab me ntsis ntawm lub teeb hlaws;
2. COB ntim tshuab
COB: Cov ntawv luv rau nti ntawm lub nkoj. Txoj kev: Chip-on-board technology; cov nti tau txuas nrog cov kab sib txuas sib txuas nrog cov khoom siv lossis cov nplaum uas tsis ua haujlwm, thiab tom qab ntawd dhau los ntawm cov txheej txheem ntim khoom ntim khoom ntawm cov hlau sib txuas, nws qhov kev sib txuas hluav taws xob tau ua tiav. Hauv ntej, lub teeb ci ntsa iab tau teeb tsa ncaj qha rau ntawm PCB, thiab taw taw tsis tas yuav tsum tau ua siab ntev. Piv nrog rau kev coj ua yooj yim SMD, lub teeb hlaws dai raug tshem tawm, thiab ob lub COB LED pob ntim nrog cov txheej txheem rov ua dua. Cov nti tau teeb tsa ncaj qha rau ntawm PCB. Yeej, tsis muaj kev txwv rau qhov loj me ntawm cov khoom ntim uas tuaj yeem npaj nrog qhov kev npaj me me. Tam sim no micro LED COB thev naus laus zis tau siv.
Piv nrog rau lwm cov thev naus laus zis ntim, txheej txheem ntawm cob tshuab yog yooj yim dua, raws li qhia hauv daim duab hauv qab no:
Led screen nta Cob ntim tshuab:
Super" ruaj khov": Yuav luag tsis muaj qhov ua tsis tiav, tsis muaj qhov tuag.
1. Super" ruaj khov": yuav luag tsis muaj qhov ua yuam kev thiab tsis muaj qhov tuag.
2. Tsis yog" dazzling": Siv cov teeb pom kev saum npoo tsis yog" dazzling" taw tes lub teeb pom kev thiab lwm yam thev naus laus zis tiv thaiv ib puag ncig. Qhov ci yog mos thiab tiv thaiv tib neeg lub qhov muag.
3. Tsis" squeaky": tsis ntshai pob, tuaj yeem so nrog dej, tiv thaiv qib IP66.
4. Tsis muaj" seam": koj tuaj yeem" kho" kev qhia meej ntawm cov nplai sib txawv.
5. Siv" lub neej ntev": 24 teev thiab 365 hnub ntawm kev siv tas li rau ntau dua 8 xyoo (kev xav txog 10 xyoo).
6." Nws yog lub neej yav tom ntej": Nws yuav hloov DLP, LCD, ntshav, projection, yeeb yaj kiab, SMD LED zaub thiab lwm yam khoom lag luam tso tawm.
Kev faib tawm ntawm lub cev sib txawv sib xws rau cov txheej txheem ntim khoom sib txawv ntawm LED zaub
Kev faib chaw ntawm lub cev sib xws sib txawv ntim cov thev naus laus zis ntawm LED zaub
Yav tom ntej, lub teeb pom kev ntawm LED tuaj yeem yog qhov me me, uas yog cov cuab yeej siv khoom siv raws li COB ntim tshuab.
