Makampani opanga kuwala kwa LED akukula mwachangu, ndipo nyali za COB LED zangowonekera kumene. Tsopano pali ukadaulo watsopano, Chithunzi cha CSP LED. Mutha kufunsa, kodi chingwe cha CSP LED ndi chiyani? Ubwino wa magetsi a CSP LED ndi chiyani? Ndiyankha mafunso awa kwa inu m'nkhaniyi. Choncho, tiyeni tiyambe.
Kodi CSP LED ndi chiyani?
CSP, kapena Chip Scale Package, imatanthawuza phukusi la LED lomwe ndi kukula kwa chipangizo cha LED, kapena osapitirira 20%. Zogulitsa za CSP zimakhala ndi zida zophatikizika zomwe sizifuna kulumikizidwa kwa waya wa solder, zomwe zimapangitsa kutsika kwamafuta, njira zochepetsera kutentha, ndi kulephera kocheperako.
Ma LED a CSP adagwiritsidwa ntchito poyang'anira zowunikira zam'manja zam'manja ndi makompyuta apakompyuta ndipo zidasinthidwa ndi makampani ndikuyika pamizere yopepuka ya board.
Kodi CSP LED Mzere ndi chiyani?
Zithunzi za CSP LED ndi ofanana ndi ochiritsira, kupatula kuti CSP LEDs ntchito, Ufumuyo kusinthasintha PCB, ndi yokutidwa ndi translucent fulorosenti guluu.
Kodi chingwe cha COB LED ndi chiyani?
COB imayimira Chip on Board pagawo la LED, zomwe zikutanthauza kuti chip cha LED chimayikidwa mwachindunji pa board board (PCB). Ma LED a "Chip on Board" a nyali zosinthika nthawi zina amatchedwa flip-chips.
The Mzere wa LED wa COB imakhala ndi tchipisi tokutidwa pa bolodi losinthika. Tchipisi makamaka ndi ma flip-chips, omwe amakhazikika pa bolodi la PCB, ndiyeno guluu wa encapsulation wosakanikirana ndi phosphor amatsitsidwa mwachindunji pa chip. Kuwala komwe kumachokera ku chip kumasinthidwa, kumawonekera, ndikulumikizana ndi phosphor, ndipo guluu limatulutsa mitundu yosiyanasiyana komanso kutentha kwamitundu yowala mofanana.
Kuti mumve zambiri, chonde werengani Zonse zomwe muyenera kudziwa musanagule chowongolera cha COB.
Kuyerekeza kwa CSP LED Mzere ndi COB LED Mzere
Maonekedwe
Guluu wa COB LED Mzere ndi wachikasu chifukwa guluu amasakanikirana ndi phosphor.
Guluu wa CSP LED Mzere ndi translucent milky woyera, ndipo palibe phosphor wosakanizidwa guluu.
Kulekerera kwamtundu
Zithunzi za CSP LED kukhala ndi kusasinthasintha kwamtundu, womwe ndi mwayi wofunikira kwambiri poyerekeza ndi mizere ya COB LED.
Chifukwa CSP LED kwenikweni ndi mkanda wa nyali, kukula kwake ndi kochepa kwambiri. Mwanjira iyi, makinawo amatha kugawa CSP LED kukhala BIN.
Chipcho chimalumikizidwa mwachindunji ndi PCB yosinthika ya COB LED mizere, kenako PCB imakutidwa ndi guluu ndi ufa wa phosphor. Kuwala koyera kumatulutsidwa ndi chip chowala cha buluu pamodzi ndi phosphor. Palibe njira yopangira COB LED mikwingwirima BINNING kudzera pamakina.
Zingwe za CSP za LED zimatha kukwaniritsa kulekerera kwa mtundu wa Macadam 3, pomwe mizere ya COB LED imatha kukwaniritsa kulekerera kwa mtundu wa Macadam 5.
Kuti mudziwe zambiri pa LED BINNING, chonde onani pansipa kanema.
Kuchita bwino
Magetsi a CSP LED kuti abwere ndi kuwala kwapamwamba kwambiri. Chifukwa pamwamba pa CSP LED Mzere wophimbidwa ndi translucent milky white guluu, ali ndi kuwala kwapamwamba transmittance.
Guluu wophimba chip umasakanizidwa ndi ma phosphor achikasu pamizere ya COB LED, kotero kuti kuyatsa kumakhala kotsika.
Kuwala kofanana
Mzere wa COB LED uli ndi kuwala kofananirako.
Mizere ya COB LED nthawi zambiri imakhala yopanda kuwala kokhala ndi kachulukidwe ka LED kofanana ndi mizere ya CSP LED.
Kutsiliza
Zithunzi za CSP LED ndi COB LED mizere ili ndi zabwino ndi zovuta zake. Nditawerenga nkhaniyi, ndikukhulupirira kuti mukudziwa kale momwe mungasankhire pakati pa mizere ya CSP LED ndi zingwe za COB LED. Kuti mudziwe zambiri za CSP led strip, mutha kuwerenga The Ultimate Guide to CSP LED Strip.
LEDYi amapanga apamwamba kwambiri Mizere ya LED ndi neon flex ya LED. Zogulitsa zathu zonse zimadutsa m'ma laboratories apamwamba kwambiri kuti zitsimikizire kuti zili bwino kwambiri. Kupatula apo, timapereka zosankha makonda pamizere yathu ya LED ndi neon flex. Chifukwa chake, pamzere wapamwamba wa LED ndi LED neon flex, kulumikizana ndi LEDYi POSACHEDWA!
