Kodi smd light strip imatanthauza chiyani?

Ndi kutchuka kwa lingaliro la kapangidwe ka "palibe kuunika kounikira", zida zowunikira zowunikira za LED zikuchulukirachulukira pakukongoletsa kwanyumba ndi mapulojekiti osintha nyumba yonse. Pali zinthu zitatu zomwe zimagwiritsidwa ntchito popanga kuwala kwa LED pamsika, zomwe ndi mizere ya SMD LED, COB LED mizere yowunikira komanso mizere yaposachedwa ya CSP LED. Ngakhale kuti mankhwala aliwonse ali ndi ubwino wake komanso kusiyana kwake, mkonzi adzayesa kugwiritsa ntchito nkhani imodzi kuti mumvetse kusiyana pakati pa atatuwa, kuti mupange chisankho choyenera.

Zingwe zowala za SMD, dzina lonse la zida zowunikira za Surface Mounted Devices (Surface Mounted Devices), zimatanthawuza kuti chip cha LED chimayikidwa mwachindunji pagawo lachingwe chowunikira, kenako ndikuyikidwa kuti apange mizere ya mikanda yaying'ono. Mzere wowala wamtunduwu ndi mtundu wamba wamtundu wowala wamtundu wa LED, womwe nthawi zambiri umakhala ndi mawonekedwe a kusinthasintha, kuwonda, kupulumutsa mphamvu, komanso moyo wautali.

SMD ndiye chidule cha "Surface Mount Device", womwe ndi mtundu wodziwika kwambiri wa chipangizo cha LED chomwe chili pamsika. Chip cha LED chimakutidwa mu chipolopolo cha bracket ya LED ndi guluu wa phosphor kenako ndikuyikidwa pa bolodi losindikizidwa losinthika (PCB). Mizere ya SMD LED ndi yotchuka kwambiri chifukwa cha kusinthasintha kwawo. , Zipangizo za LED za SMD zimabwera mosiyanasiyana: 3528, 5050, 2835, 3014, 2216, 2110; nthawi zambiri amatchedwa molingana ndi kukula kwake, mwachitsanzo, kukula kwa 3528 ndi 3.5 x 2.8mm, 5050 ndi 5.0 x 5.0mm, ndi 2835 ndi 2.8 x 3.5mm, 3014 ndi 3.0 x 1.4mm.

Popeza zingwe zopepuka za SMD za LED zimagwiritsa ntchito zigawo zosiyana za SMD LED, mtunda / kusiyana pakati pa zida ziwiri zoyandikana ndi LED ndizokulirapo. Mzere wowala ukayatsidwa, mutha kuwona zowunikira pawokha. Anthu ena amanena kuti Kwa malo otentha kapena zowunikira. Chifukwa chake ngati simukufuna kuwona malo otentha kapena mawanga owala, muyenera kugwiritsa ntchito zofunda (monga chivundikiro cha pulasitiki) kuti muyike pamwamba pa mzere wa SMD LED, ndipo muyenera kusiya kutalika kokwanira kuti kusanganikirana kwa kuwala kudule. mawanga owala Bright spot effect, kotero mbiri ya aluminiyamu yomwe imagwiritsidwa ntchito nthawi zambiri imakhala yokhuthala.

Mzere wowala wa COB, dzina lonse ndi Chips On Board Mzere woyatsa wa LED, ndi mtundu wamtundu wowala wa LED wokhala ndi chip pa bolodi (Chips On Board). Poyerekeza ndi mizere yowunikira ya SMD, mizere yowunikira ya COB imayika tchipisi tambiri ta LED pa bolodi yozungulira kuti ipange malo okulirapo otulutsa kuwala, omwe nthawi zambiri amagwiritsidwa ntchito pamachitidwe omwe amafunikira kuyatsa kofanana.

Chifukwa cha zokutira zomatira za phosphor mosalekeza, zingwe za COB LED zimatha kutulutsa kuwala kofananira popanda kuwala kowoneka bwino, kotero zimatha kutulutsa kuwala kofananira kosasinthasintha popanda kufunikira kwa zovundikira zapulasitiki zowonjezera. , ngati mukufunikirabe kugwiritsa ntchito zitsulo za aluminiyamu, mutha kusankha mbiri zoonda kwambiri za aluminiyamu.

CSP ndi imodzi mwa matekinoloje aposachedwa kwambiri pamakampani a LED. M'makampani a LED, CSP imatanthawuza mawonekedwe ang'onoang'ono komanso osavuta kwambiri opanda waya kapena waya wagolide. Mosiyana ndi ukadaulo wa SMD light strip board, CSP imagwiritsa ntchito ma board osinthika a FPC osinthika.

FPC ndi chingwe chamtundu watsopano wopangidwa ndi filimu yotsekereza ndi waya woonda kwambiri wamkuwa, womwe umakanizidwa palimodzi kudzera mumzere wopangira zida zodziwikiratu. Lili ndi ubwino wofewa, kupindika ndi kupindika kwaulere, makulidwe owonda, kukula kochepa, kulondola kwambiri, ndi kuwongolera mwamphamvu.

Poyerekeza ndi ma CD achikhalidwe, ma CD a CSP ali ndi njira yosavuta, yotsika mtengo, yotsika mtengo, ndipo mbali yotulutsa kuwala ndi njira zake ndizokulirapo kuposa mitundu ina yazoyika. Chifukwa cha kuyika kwake, mizere yowunikira ya CSP imatha kukhala yaying'ono, yopepuka komanso yopepuka, ndipo imakhala ndi zopanikiza zing'onozing'ono. Nthawi yomweyo, mbali yake yotulutsa kuwala ndi yayikulu, ikufika 160 °, ndipo utoto wowala ndi woyera komanso wofewa, wopanda m'mphepete mwachikasu. Chofunikira chachikulu pamizere yowunikira ya CSP ndikuti satha kuwona kuwala ndipo ndi ofewa komanso osawoneka bwino.
