1. Taw qhia
Raws li LED zaub screen daim ntawv thov tau nthuav dav, qhov kev xav tau ntawm cov khoom lag luam zoo thiab kev ua haujlwm tau nce ntxiv. Ib txwm siv tshuab SMD tsis tuaj yeem ua tau raws li cov kev xav tau ntawm qee cov ntawv thov. Yog li ntawd, qee cov tuam txhab lag luam tau hloov mus rau cov txheej txheem encapsulation tshiab xws li COB thev naus laus zis, thaum lwm tus tab tom txhim kho SMD thev naus laus zis. GOB thev naus laus zis yog qhov rov ua dua tshiab ntawm SMD encapsulation txheej txheem.
Kev lag luam LED zaub tau tsim ntau txoj hauv kev encapsulation, suav nrog COB LED zaub. Los ntawm qhov ua ntej DIP (Direct Insertion Package) thev naus laus zis mus rau SMD (Nto-Mount Device) thev naus laus zis, tom qab ntawd mus rau qhov tshwm sim ntawm COB (Chip on Board) encapsulation, thiab thaum kawg lub advent ntawm GOB (Kua rau Board) encapsulation.
GOB thev naus laus zis puas tuaj yeem ua rau cov ntawv thov dav dua rau cov ntxaij vab tshaus LED? Peb tuaj yeem xav li cas rau yav tom ntej kev lag luam kev loj hlob ntawm GOB? Cia peb mus.
2. GOB Encapsulation Technology yog dab tsi?
2.1GOB LED zaubyog ib qho kev tiv thaiv zoo heev LED zaub screen, muab cov dej tsis muaj dej, noo noo-pov thawj, cuam tshuam-resistant, plua plav-pov thawj, corrosion-resistant, xiav lub teeb-resistant, ntsev-resistant, thiab anti-static muaj peev xwm. Lawv tsis cuam tshuam rau tshav kub dissipation lossis brightness poob. Kev sim dav dav qhia tau hais tias cov kua nplaum siv hauv GOB txawm pab ua kom sov dissipation, txo qhov tsis ua haujlwm ntawm LEDs, txhim kho qhov ruaj khov ntawm cov zaub, thiab yog li txuas ntxiv nws txoj sia.
2.2 Los ntawm kev ua GOB, yav dhau los granular pixel cov ntsiab lus ntawm GOB LED npo qhov chaw tau hloov mus rau hauv ib qho chaw du, tiaj tus, ua tiav qhov kev hloov pauv ntawm qhov chaw teeb pom kev mus rau qhov chaw teeb pom kev zoo. Qhov no ua rau LED npo vaj huam sib luag lub teeb emissions ntau dua thiab cov duab pom pom tseeb dua thiab pob tshab. Nws txhim khu kev pom lub kaum ntse ntse (ze li 180 ° kab rov tav thiab ntsug), tshem tawm cov qauv moiré zoo, txhim kho cov khoom sib piv zoo, txo qhov ci ntsa iab thiab dazzling cuam tshuam, thiab txo qhov pom kev qaug zog.
3. COB Encapsulation Technology yog dab tsi?
COB encapsulation txhais tau tias ncaj qha txuas cov nti mus rau PCB substrate rau kev sib txuas hluav taws xob. Nws yog thawj zaug qhia los daws qhov teeb meem kub dissipation ntawm LED video phab ntsa. Piv nrog rau DIP thiab SMD, COB encapsulation yog tus cwj pwm los ntawm qhov chaw txuag, yooj yim encapsulation kev ua haujlwm, thiab kev tswj xyuas thermal. Tam sim no, COB encapsulation yog siv nyob rau hauvzoo suab LED zaub.
4. Dab tsi yog qhov zoo ntawm COB LED zaub?
Ultra-nyias thiab lub teeb:Raws li cov neeg siv khoom xav tau, PCB boards nrog thicknesses li ntawm 0.4 mus rau 1.2 hli tuaj yeem siv tau, txo qhov hnyav kom tsawg li ib feem peb ntawm cov khoom lag luam, txo qis cov qauv, kev thauj mus los, thiab cov nqi engineering rau cov neeg siv khoom.
Impact thiab Pressure Resistance:COB LED zaub encapsulates LED nti ncaj qha rau hauv txoj hauj lwm concave ntawm PCB board, ces encapsulates thiab kho nws nrog epoxy resin kua nplaum. Qhov saum npoo ntawm lub teeb taw tes protrudes, ua rau nws du thiab tawv, cuam tshuam-resistant, thiab hnav-resistant.
Wide Viewing Angle:COB encapsulation siv qhov ntiav ntiav zoo kheej kheej lub teeb emission, nrog lub kaum sab xis saib ntau dua 175 degrees, ze rau 180 degrees, thiab muaj qhov zoo tshaj plaws kho qhov muag diffused lub teeb.
Muaj zog Thaum tshav kub kub Dissipation:COB LED npo encapsulates lub teeb ntawm PCB lub rooj tsavxwm, thiab cov ntawv ci tooj liab ntawm PCB pawg thawj coj saib xyuas cov cua sov ntawm lub teeb ci. Cov ntawv ci tooj liab tuab ntawm PCB pawg thawj coj saib muaj cov txheej txheem nruj, ua ke nrog cov txheej txheem kub-plating, yuav luag tshem tawm qhov teeb meem loj heev. Yog li, muaj ob peb lub teeb tuag, ua rau lub neej ntev heev.
Hnav-Resistant thiab yooj yim los ntxuav:COB LED cov ntxaij vab tshaus saum npoo ntawm lub teeb taw tes protrudes rau hauv cov duab kheej kheej, ua rau nws du thiab tawv, cuam tshuam-resistant thiab hnav-resistant. Yog hais tias qhov tsis zoo tshwm sim, nws tuaj yeem kho qhov taw tes los ntawm taw tes. Tsis muaj daim npog qhov ncauj, thiab plua plav tuaj yeem ntxuav nrog dej lossis ntaub.
All-Weather Excellence:Triple kev tiv thaiv kev kho mob muab cov dej tsis zoo, noo noo-pov thawj, corrosion-pov thawj, plua plav pov thawj, tiv thaiv zoo li qub, oxidation, thiab UV tsis kam. Nws tuaj yeem ua haujlwm ib txwm nyob hauv qhov chaw kub ntawm -30 ° C txog 80 ° C.
5. Qhov txawv ntawm COB thiab GOB yog dab tsi?
Qhov sib txawv tseem ceeb ntawm COB thiab GOB yog nyob rau hauv tus txheej txheem. Txawm hais tias COB encapsulation muaj lub ntsej muag du thiab kev tiv thaiv zoo dua li cov tsoos SMD encapsulation, GOB encapsulation ntxiv cov txheej txheem ua kua nplaum rau ntawm qhov screen, txhim kho qhov ruaj khov ntawm LED teeb thiab txo qis qhov tshwm sim ntawm lub teeb poob, ua rau nws ruaj khov dua.
6. Qhov twg yog Qhov Zoo Tshaj Plaws, COB lossis GOB?
Tsis muaj cov lus teb meej rau qhov twg yog qhov zoo dua, COB LED zaub lossis GOB LED zaub, vim tias qhov zoo ntawm lub tshuab encapsulation nyob ntawm ntau yam. Qhov kev txiav txim siab tseem ceeb yog seb koj puas ua ntej qhov ua tau zoo ntawm LED teeb lossis kev tiv thaiv muaj. Txhua lub tshuab encapsulation muaj nws qhov zoo thiab tsis tuaj yeem txiav txim siab thoob ntiaj teb.
Thaum xaiv ntawm COB thiab GOB encapsulation, nws yog ib qho tseem ceeb uas yuav tau xav txog lub installation ib puag ncig thiab lub sijhawm ua haujlwm. Cov xwm txheej no cuam tshuam txog kev tswj hwm tus nqi thiab qhov sib txawv ntawm kev ua haujlwm ntawm kev ua yeeb yam.
