Kodi chiwonetsero cha COB LED ndi chiyani?

Chiwonetsero cha COB LED chimayimira "Chip-on-Board Light Emitting Diode". Ndi mtundu waukadaulo wa LED momwe ma tchipisi angapo a LED amayikidwa mwachindunji pagawo kuti apange gawo limodzi kapena gulu. Mu chiwonetsero cha COB LED, tchipisi tating'ono ta LED tadzaza pamodzi ndikukutidwa ndi zokutira za phosphor zomwe zimatulutsa kuwala mumitundu yosiyanasiyana.

Kodi ukadaulo wa COB ndi chiyani?

Ukadaulo wa COB, womwe umayimira "chip-on-board," ndi njira yolumikizira zida za semiconductor momwe tchipisi tambiri zophatikizika zimayikidwa mwachindunji pagawo laling'ono kapena bolodi. Tchipisi izi nthawi zambiri zimadzaza pamodzi molimba ndipo zimakutidwa ndi utomoni woteteza kapena ma epoxy resins. Muukadaulo wa COB, tchipisi tating'onoting'ono ta semiconductor nthawi zambiri timamangiriridwa molunjika ku gawo lapansi pogwiritsa ntchito njira zolumikizirana ndi lead kapena flip chip bonding. Kuyika kwachindunji kumeneku kumathetsa kufunikira kwa tchipisi tomwe timakhala ndi nyumba zosiyana.

M'zaka zaposachedwa, ukadaulo wa COB (Chip-on-Board) wawona kupita patsogolo ndi zatsopano zingapo, motsogozedwa ndi kufunikira kwa zida zazing'ono, zogwira ntchito bwino, komanso zotsogola kwambiri.

SMD vs. COB Packaging Technology

1. Poyerekeza ndi teknoloji ya SMD, teknoloji ya COB imalola kuti pakhale mgwirizano wapamwamba kwambiri mwa kuphatikiza chipangizo cha LED mwachindunji pa gawo lapansi. Kuchulukana kotereku kumabweretsa zowonetsera zokhala ndi milingo yowala kwambiri komanso kuwongolera bwino kwa kutentha. Ndi COB, tchipisi ta LED timamangiriridwa mwachindunji ku gawo lapansi, zomwe zimathandizira kuti kutentha kutheke bwino. Izi zikutanthauza kuti kudalirika ndi moyo wonse wa zowonetsera za COB zimakhala bwino, makamaka pakuwala kwambiri komwe kumayang'anira kutentha ndikofunikira.

2. Chifukwa cha mapangidwe awo, ma COB LED ndi odalirika kwambiri kuposa ma SMD LED. COB ili ndi zolephera zochepa kuposa SMD, pomwe chipangizo chilichonse cha LED chimayikidwa payekhapayekha. Kulumikizana mwachindunji kwa tchipisi ta LED muukadaulo wa COB kumachotsa zinthu zotsekera mu ma SMD ma LED, kuchepetsa chiwopsezo chakuwonongeka pakapita nthawi. Zotsatira zake, zowonetsera za COB zimakhala ndi zolephera zocheperako za LED komanso kudalirika kwakukulu pakugwirira ntchito mosalekeza m'malo ovuta.

3. Ukadaulo wa COB umapereka maubwino okwera mtengo kuposa ukadaulo wa SMD, makamaka pamapulogalamu owala kwambiri. Pochotsa kufunikira kwa kulongedza munthu payekha ndikuchepetsa zovuta zopanga, zowonetsera za COB zimakhala zotsika mtengo kupanga. Njira yolumikizirana mwachindunji muukadaulo wa COB imathandizira kupanga mosavuta ndikuchepetsa kugwiritsa ntchito zinthu, potero kutsitsa mtengo wonse wopanga.

4. Kuphatikiza apo, ndi ntchito yake yabwino kwambiri yosalowa madzi, yosagwira fumbi komanso yoletsa kugundana,Chiwonetsero cha COB LEDitha kugwiritsidwa ntchito modalirika komanso mokhazikika m'malo ovuta osiyanasiyana.

Zoyipa za COB LED chiwonetsero

Zachidziwikire, tiyeneranso kulankhula za kuipa kwa zowonera za COB.

· Mtengo Wokonza: Chifukwa cha mapangidwe apadera a COB LED zowonetsera, kukonza kwawo kungafunike chidziwitso chapadera kapena maphunziro. Mosiyana ndi mawonedwe a SMD pomwe ma module a LED amatha kusinthidwa mosavuta, mawonetsedwe a COB nthawi zambiri amafunikira zida zapadera ndi ukadaulo kuti akonze, zomwe zingayambitse nthawi yayitali pakukonza kapena kukonza.

Kuvuta Kwa Kusintha Mwamakonda: Poyerekeza ndi matekinoloje ena owonetsera, zowonetsera za COB LED zimatha kubweretsa zovuta pakusintha mwamakonda. Kukwaniritsa zofunikira zapangidwe kapena masinthidwe apadera kungafunike ntchito yowonjezera yaumisiri kapena kusintha mwamakonda, zomwe zimatha kutalikitsa nthawi ya polojekiti kapena kuonjezera mtengo.

Chifukwa chiyani Sankhani RTLED's COB LED Display?

Ndili ndi zaka zopitilira khumi pakupanga ma LED,RTLEDzimatsimikizira khalidwe lapamwamba ndi kudalirika. Timapereka upangiri waukadaulo wotsatsa malonda ndi chithandizo pambuyo pogulitsa, mayankho osinthidwa makonda, ndi ntchito zokonza kuti zikwaniritse makasitomala athu. Zowonetsa zathu zidakhazikitsidwa bwino mdziko lonse. Kuphatikiza apo,RTLEDimapereka mayankho okhazikika kuyambira pakupanga mpaka kukhazikitsa, kufewetsa kasamalidwe ka polojekiti ndikupulumutsa nthawi ndi mtengo.Lumikizanani nafe tsopano!
