Siyini isibonisi se-COB LED?

I-COB LED display imele isibonisi esithi “Chip-on-Board Light Emitting Diode”. Iwuhlobo lobuchwepheshe be-LED lapho ama-chips e-LED amaningi afakwa khona ngqo ku-substrate ukuze akhe imojuli eyodwa noma amalungu afanayo. Kusibonisi se-COB LED, ama-chips e-LED angawodwana ahlanganiswe ahlanganiswe futhi ambozwe nge-phosphor coating ekhipha ukukhanya ngemibala ehlukahlukene.

Buyini ubuchwepheshe be-COB?

Ubuchwepheshe be-COB, obumele "i-chip-on-board," buyindlela yokuhlanganisa amadivaysi e-semiconductor lapho ama-chips esekethe amaningi ahlanganisiwe afakwa ngqo ku-substrate noma ibhodi lesekethe. Lawa ma-chips avame ukupakishwa ngokuqinile ndawonye futhi ambozwe ngama-resin okuvikela noma ama-epoxy resins. Kubuchwepheshe be-COB, ama-semiconductor ama-chips angawodwana ngokuvamile ahlanganiswa ngokuqondile ne-substrate kusetshenziswa amasu okubopha umthofu noma ama-flip chip bonding. Lokhu kufakwa okuqondile kuqeda isidingo sama-chips apakishwe ngokwejwayelekile anezindlu ezihlukene.

Eminyakeni yakamuva, ubuchwepheshe be-COB (Chip-on-Board) buye babona ukuthuthuka nokuqanjwa okusha, okuqhutshwa isidingo semishini kagesi emincane, esebenza kahle kakhulu futhi esebenza kakhulu.

I-SMD vs. COB Packaging Technology

1. Uma kuqhathaniswa nobuchwepheshe be-SMD, ubuchwepheshe be-COB buvumela izinga eliphezulu lokuhlanganisa ngokuhlanganisa i-chip ye-LED ngqo ku-substrate. Lokhu kuminyana okuphezulu kubangela izibonisi ezinamaleveli aphezulu okukhanya nokuphathwa okungcono kokushisa. Nge-COB, ama-chips e-LED aboshwe ngokuqondile ku-substrate, okusiza ukuqeda ukushisa okuphumelelayo. Lokhu kusho ukuthi ukwethembeka nempilo yonke yezibonisi ze-COB kuyathuthukiswa, ikakhulukazi ezinhlelweni zokukhanya okuphezulu lapho ukuphathwa kokushisa kubaluleke kakhulu.

2. Ngenxa yokwakhiwa kwawo, ama-COB LED ngokwemvelo athembeke kakhulu kunama-SMD LED. I-COB inamaphuzu ambalwa okuhluleka kune-SMD, lapho i-chip ngayinye ye-LED ihlanganiswe ngayodwana. Ukuhlanganiswa okuqondile kwama-chips e-LED kubuchwepheshe be-COB kususa izinto zokuhlanganisa kuma-SMD LED, kunciphisa ubungozi bokuwohloka ngokuhamba kwesikhathi. Njengomphumela, izibonisi ze-COB zinokuhluleka kwe-LED okumbalwa kanye nokuthembeka okukhulu okuphelele kokusebenza okuqhubekayo ezindaweni ezinokhahlo.

3. Ubuchwepheshe be-COB bunikeza izinzuzo zezindleko kunobuchwepheshe be-SMD, ikakhulukazi ezinhlelweni zokukhanya okuphezulu. Ngokususa isidingo sokupakishwa komuntu ngamunye kanye nokunciphisa inkimbinkimbi yokukhiqiza, izibonisi ze-COB zibiza kakhulu ukukhiqiza. Inqubo yesibopho esiqondile kubuchwepheshe be-COB yenza inqubo yokukhiqiza ibe lula futhi inciphise ukusetshenziswa kwezinto ezibonakalayo, ngaleyo ndlela yehlise izindleko zokukhiqiza zizonke.

4. Ngaphezu kwalokho, ngokusebenza kwayo okuphezulu okungangeni manzi, ukuvikela uthuli nokungqubuzana,Isibonisi se-COB LEDingasetshenziswa ngendlela enokwethenjelwa futhi ngokuzinza ezindaweni ezihlukahlukene ezinokhahlo.

Ukungalungi kwesibonisi se-COB LED

Yebo kufanele sikhulume ngobubi bezikrini ze-COB futhi.

· Izindleko Zokulungisa: Ngenxa yokwakhiwa okuyingqayizivele kwezibonisi ze-COB LED, ukugcinwa kwazo kungadinga ulwazi olukhethekile noma ukuqeqeshwa. Ngokungafani nezibonisi ze-SMD lapho amamojula e-LED angawodwana angashintshwa kalula, izibonisi ze-COB zivame ukudinga imishini ekhethekile nobungcweti ukuze kulungiswe, okungaholela ekunciphiseni isikhathi eside ngesikhathi sokulungiswa noma ukulungiswa.

· Ukuba yinkimbinkimbi Kokwenza Ngokwezifiso: Uma kuqhathaniswa nobunye ubuchwepheshe bokubonisa, izibonisi ze-COB LED zingaletha izinselelo ezithile uma kuziwa ekwenzeni ngokwezifiso. Ukufinyelela izimfuneko ezithile zedizayini noma ukulungiselelwa okuyingqayizivele kungase kudinge umsebenzi wobunjiniyela owengeziwe noma ukwenza ngendlela oyifisayo, okunganweba kancane imigqa yesikhathi yephrojekthi noma kwenyuse izindleko.

Kungani Khetha i-RTLED's COB LED Display?

Ngesipiliyoni esingaphezu kweminyaka eyishumi ekukhiqizeni isibonisi se-LED,I-RTLEDiqinisekisa izinga eliphezulu nokuthembeka. Sihlinzeka ngokubonisana kwangaphambili kokuthengisa kanye nokwesekwa kwangemuva kokuthengisa, izixazululo ezenziwe ngokwezifiso, nezinsizakalo zokulungisa ngendlela egculisayo amakhasimende ethu. Izibonisi zethu zifakwe ngempumelelo ezweni lonke. Ngaphezu kwalokho,I-RTLEDinikeza izixazululo zokuma okukodwa kusukela ekuklanyeni kuya ekufakweni, ukwenza lula ukuphathwa kwephrojekthi nokonga isikhathi nezindleko.Xhumana nathi manje!
