Isho ukuthini i-smd light strip?

Ngokuduma komqondo wokuklama othi "akukho ukukhanya okuyinhloko", imikhiqizo yomugqa wokukhanya womugqa we-LED iya ngokuya iduma emhlobiso wasekhaya kanye namaphrojekthi okwenza ngokwezifiso indlu yonke. Kunemikhiqizo emithathu evamile ye-LED evumelana nezimo emakethe, okuyimichilo yokukhanya ye-SMD LED, imichilo yokukhanya ye-COB LED kanye nemichilo yakamuva yokukhanya ye-CSP LED. Nakuba umkhiqizo ngamunye unezinzuzo kanye nokwehluka kwawo, umhleli uzozama ukusebenzisa isihloko esisodwa ukuze akuvumele uqonde umehluko phakathi kwalokhu okuthathu, ukuze ukwazi ukwenza ukukhetha okufanele.

Imichilo yokukhanya ye-SMD, igama eligcwele lama-Surface Mounted Devices (Surface Mounted Devices) imichilo yokukhanya, ibhekisela ku-chip ye-LED ebekwe ngokuqondile ku-substrate yomugqa wokukhanya, bese ihlanganiswa ukuze yakhe imigqa yobuhlalu besibani obuncane. Lolu hlobo lomucu wokukhanya wuhlobo olujwayelekile lwesibani se-LED, ngokuvamile esinezici zokuguquguquka, ubuncane, ukonga amandla, nempilo ende.

I-SMD isifinyezo se-"Surface Mount Device", okuwuhlobo oluvame kakhulu lwedivayisi ye-LED okwamanje emakethe. I-chip ye-LED ifakwe kugobolondo lobakaki we-LED ngeglue ye-phosphor bese ifakwa ebhodini lesifunda eliphrintiwe elivumelana nezimo (PCB). Imichilo ye-SMD LED idume kakhulu ngenxa yokuguquguquka kwayo. , Amadivayisi we-SMD LED afika ngobukhulu obuhlukahlukene: 3528, 5050, 2835, 3014, 2216, 2110; ngokuvamile zibizwa ngokuhambisana nobukhulu bazo, isibonelo, ubukhulu be-3528 bungu-3.5 x 2.8mm, 5050 bungu-5.0 x 5.0mm, futhi u-2835 ngu-2.8 x 3.5mm, u-3014 ngu-3.0 x 1.4mm.

Njengoba imichilo yokukhanya eguquguqukayo ye-SMD evamile ye-SMD isebenzisa izingxenye ezihlukene ze-SMD LED, ibanga/igebe phakathi kwamadivayisi amabili aseduze e-LED likhulu uma kuqhathaniswa. Lapho umugqa wokukhanya ukhanyisiwe, ungabona amaphuzu akhanyayo ngamanye. Abanye abantu bathi Okwezindawo ezishisayo noma okuvelele. Ngakho-ke uma ungafuni ukubona izindawo ezishisayo noma izindawo ezikhanyayo, udinga ukusebenzisa okuthile okusibekela (okufana nesembozo sepulasitiki) ukuze usibeke phezu komugqa we-SMD LED, futhi kufanele ushiye ubude obanele ukuze ukuxuba ukukhanya kusike. amabala akhazimulayo Umphumela wamabala agqamile, ngakho-ke amaphrofayili e-aluminium avame ukusetshenziswa aminyene.

Umugqa wokukhanya we-COB, igama eligcwele umugqa wokukhanya we-Chips On Board we-LED, uwuhlobo lwesibani se-LED esine-chip on board package (Chips On Board). Uma kuqhathaniswa nemigqa yokukhanya ye-SMD, imichilo yokukhanya ye-COB ipakisha ngokuqondile ama-chips amaningi e-LED ebhodini lesifunda ukuze kwakhe indawo enkulu ekhipha ukukhanya, evame ukusetshenziswa ezimeni zohlelo ezidinga ukukhanya okufanayo.

Ngenxa yokunamathela okuqhubekayo kwe-phosphor glue, imichilo ye-COB LED ingakhipha ukukhanya okufanayo ngaphandle kwendawo eyodwa yokukhanya esobala kakhulu, ukuze ikwazi ukukhipha ukukhanya okuphumayo ngokulinganayo nokuvumelana okuhle ngaphandle kwesidingo sezembozo zepulasitiki ezengeziwe. , uma usadinga ukusebenzisa izitsha ze-aluminium, ungakhetha amaphrofayili amancane kakhulu we-aluminium flat.

I-CSP ingobunye bobuchwepheshe bakamuva embonini ye-LED. Embonini ye-LED, i-CSP isho ifomu lephakheji elincane nelilula kunawo wonke ngaphandle kwe-substrate noma intambo yegolide. Ihlukile kubuchwepheshe bebhodi lomugqa wokukhanya we-SMD, i-CSP isebenzisa amabhodi esekethe e-FPC aguquguqukayo e-roll-to-roll.

I-FPC iwuhlobo olusha lwekhebula elenziwe ngefilimu evikelayo kanye nentambo yethusi eyisicaba ezacile kakhulu, ecindezelwa ndawonye ngomugqa wokukhiqiza wemishini yokugcwalisa i-laminating ezenzakalelayo. Inezinzuzo zokuthamba, ukugoba nokugoqa kwamahhala, ukujiya okuncanyana, usayizi omncane, ukunemba okuphezulu, kanye ne-conductivity eqinile.

Uma kuqhathaniswa nokupakishwa kwe-SMD evamile, ukupakishwa kwe-CSP kunenqubo elula, okusebenzisekayo okuncane, izindleko eziphansi, kanye ne-engeli ekhipha ukukhanya nokuqondisa kukhulu kakhulu kunamanye amafomu okupakisha. Ngenxa yemininingwane yenqubo yayo yokupakisha, imichilo yokukhanya ye-CSP ingaba mincane, ibe lula futhi ibe lula, futhi ibe namaphoyinti wokugoba amancane. Ngesikhathi esifanayo, i-engeli yayo ekhipha ukukhanya inkulu, ifinyelela ku-160 °, futhi umbala okhanyayo uhlanzekile futhi uthambile, ngaphandle kwemiphetho ephuzi. Isici esikhulu kunazo zonke se-CSP light strips ukuthi azikwazi ukubona ukukhanya futhi zithambile futhi zibuthuntu.
