Ezimweni zanamuhla ezithuthuka ngokwezobuchwepheshe, izixazululo zokubonisa eziholwayo ziye zavela kakhulu. Ubuchwepheshe be-LED buguqule imboni yokukhanyisa, ukuhlinzeka ngezinketho ezisebenza kahle nezihlala isikhathi eside kubathengi nakumabhizinisi ngokufanayo. Phakathi kokucushwa okuhlukahlukene kwe-LED, i-COB (chip ebhodini) ivele njengekhetho eliphakeme ngenxa yezimpawu zalo zobuchwepheshe. Kulesi sihloko, sizokwehlela ngenxa yezizathu zokuthi kungani uCob ephethe inzuzo ngaphezulu kobuchwepheshe obusetshenziswa kabanzi be-SMD (i-Surface Mount). Ukusuka ekukhuphukeni kwayo okuphansi okuphansi ukuze uthuthukise ukuvikeleka ezintweni zezemvelo, uCob ukhipha izimbangi zawo.
1.SMD vs COB: Yikuphi okungcono?
Uma kukhulunywa ngobuchwepheshe bombukiso we-LED, abaphikisi ababili abaphambili babusa imakethe: SMD noCob. Ngenkathi idivaysi yeNtaba ye-Surface Sekuyisikhathi eside ingukuzikhethela kwezixazululo zokukhanyisa eziholayo, uCob uqhamuke njengenye indlela enamandla.
Ngokungafani ne-SMD, equkethe ama-diode e-LED ahlanganisiwe ebhodini lesekethe, i-COB ifaka ama-chips aholwa amaningana ngaphakathi kwemodyuli eyodwa. Lokhu kulungiswa okuyingqayizivele akukukhulisanga ukugqama nokuqina kokukhanya kodwa futhi kunciphisa i-attenciation yokukhanya kumabanga amade. Design-onqenqemeni lokusika kukaCob kuphumela ekukhishweni okukhanyayo okungenamsoco ngokufana nokuhunyushwa kombala okuphezulu.
II. Okushisayo okuphansi okushisayo okushisayo
Enye yezinzuzo eziyinhloko ze-COB ngaphezulu kwe-SMD amakhono ayo okuphathwa okuphezulu okuphezulu. I-COB Technology inikezela ukumelana okushisayo okuphansi ngenxa yokwakheka kwayo okuhlangene. Ukumelana okushisayo kunquma ukuthi ukushisa kuqeda kanjani kusuka kumodyuli ye-LED, okwenza i-cob isebenze kahle ngokunciphisa ukwakha ukushisa. Lokhu kuphumela hhayi kuthuthukiswe isikhathi eside kuphela futhi kuncishiswe izidingo zokulungiswa kepha futhi kuthuthukiswe ukuphepha njengobaAmamojula we-COBathambekele kangako ekushiseni ngokweqile.
III. Ukuvikelwa okuhle kakhulu ezintweni zezemvelo
Ukuboniswa kwe-cobInikeza ukuvikela okuhle kakhulu ekulweni nezici ezahlukahlukene zemvelo, ukuqinisekisa ukuqina nokwethembeka ezimeni ezahlukahlukene. Welashwa nge-epoxy resin ukuthuthukisa ukusebenza okuvikelayo. Iqhakaza ukumelana okuphezulu kumswakama, uthuli, olubi, oxidation, nokukhanya okuluhlaza okwesibhakabhaka. Lokhu kuvikelwa okuthuthukisiwe kunika amandla izixazululo zokukhanyisa ama-cob ukuchuma ezindaweni eziyinselele njengezilungiselelo zangaphandle noma izindawo ezinomswakama ophezulu. Ngokwengeziwe, ukumelana kukaCob okuphakeme ku-oxidation kuqinisekisa ukuthi ama-LED agcina ukugqama kwawo kanye nokunemba kwemibala ngaphezulu kwezikhathi ezengeziwe, ngokungafani nabalingani babo be-SMD.
IV. Ikhwalithi emnyama nebukhali.
Ukwakhiwa kweCob Technology akukukhulisanga kuphela amakhono alo wokuphatha kanye nokuvikela kuphela kepha futhi kufaka nekhwalithi yokukhanyisa. Ngenxa yama-chip we-LED ahlelwe eduze, uCob ukhipha umugqa ogxile kakhulu futhi onamandla okukhanya, okuholela kumathunzi amnyama nemininingwane ye-crisper. Lokhu kwenza i-COB ilungele izinhlelo zokusebenza lapho ukunemba khona kanye nokwehluka okuphezulu kubaluleke kakhulu, njengeminyuziyamu, ukuboniswa kwezitolo, kanye nemibukiso. Ukukhanyisa okubukhali okunikezwe ubuchwepheshe be-COB kuthuthukisa isikhalazo esibonakalayo nokucaciswa kwezikhala ezikhanyisiwe.
Njengoba imboni yokubonisa ye-LED iyaqhubeka nokuvela,Ubuchwepheshe be-cobKuvele njengokhetho olusha noluphakeme lwezixazululo zokubonisa. Izici zayo zobuchwepheshe, njengokukhipha okufanayo kokukhanya, ukuphuma okushisayo, ukuvikelwa okuthuthukile ezimweni zezemvelo, nokukhanyisa okubukhali, kwenze kube nenketho engabekezeleleki. I-COB ayihlinzeki kuphela ukusebenza okuthuthukile nokuphila isikhathi eside kodwa futhi inikeza ikhwalithi engcono yokubuka, ebalulekile kwizicelo ezahlukahlukene.
Ngokuthandwa kwayo okwandayo nokuthuthuka ekukhiqizweni kwezinqubo,Ubuchwepheshe be-cobiyatholakala kalula kubathengi nakumabhizinisi emhlabeni jikelele. Ukuhlanganisa Ukuboniswa kwe-cobIzixazululo zithembisa ukuletha izinketho ezikhanyayo, ezisebenza kahle, ezisebenza isikhathi eside ngenkathi zishintsha indlela esikhanyisela ngayo okukuzungezile.
