Ukwenyuka Kwezinga Lokungamelana Nezinga Lokukhanya Kwesakhiwo Se-Diode Ekhipha Ukukhanya

Ama-chips athela ubuhlalu be-LED, amakhono angapakishiwe asanda kubangela ibhizinisi lobuchwepheshe obuphezulu embonini ye-LED. Ngenxa yobuhlalu besibani bendabuko be-LED, inqubo yokwakheka kokubunjwa kokushisa kokushisa, ukwehluleka kokukhanya kanye namanye amabhodlela amakhono. Isibani se-LED sithela ama-chips namakhono angapakishiwe ekuqaleni kweminyaka eyi-10 edlule, amazwe angaphandle ukutshala imali ocwaningweni olukhulu lwemali. Okuhloswe ngayo ubuhlalu besibani se-LED kusuka ku-substrate glue kanye namakhono wokushisela okusanhlamvu okuqondile. Iqedwa ngokuphelele ubuhlalu besibani se-LED ama-chips asemthethweni ekubukeni kwezifo eziningi zezinwele, okuvumela ubuhlalu besibani se-LED ukuthi bumelane nokubekezelelana kwezinga lokushisa eliphakeme kanye nokwelula ubuhlalu besibani se-LED. Imboni iphezu kwamakhono aphambili okupakisha ubuhlalu besibani se-LED. & LED Lighting Daspeed Bangaki wnbsp; kodwa umbuzo uwukuthi: Kungani isibani se-LED amakhono okuthulula ubuhlalu? Ukuthembela kuma-substrates e-aluminium (ithusi), i-ceramic substrate processing molding, kanye nokufakwa akulula njengama-substrates ensimbi, ngoba (kabili) i-tin welding kufanele imelane nama-degrees angu-280 okushisa okuphezulu, okungenakukwazi ukusiza kodwa kubangele umonakalo ezintweni kanye nezingxenye. Ama-substrates e-Ceramic nama-metal substrates awaphezulu kunezinga lokubonisa, futhi umphumela wokukhanya odlulayo kunzima ukuwuthuthukisa. Izinga lokushisa elilinganiselwe lama-substrates e-ceramic kanye nendawo yokuxhumana ye-chip elinganiselwe nakho kukhawule umphumela wako wokukhanya ozinzile. Inqubo yokuthela ubuhlalu besibani se-LED kabili phakathi kwe-tin welding kanye ne-ceramic substrate aluminium substrate ekabili ukumelana nokushisa kwanele ukuvala umoya ongenhla osanda kushiwo. Ngaphezu kwalokho, ukushisa kwengcindezi yokushisa kanye ne-reflux welding yobuhlalu belambu le-LED kuphezulu kakhulu, futhi isivuno asizinzile. Ngokombono wabasebenzisi bokugcina, idivayisi ye-LED enhle kufanele ibe nekhwalithi yokukhanya engcono, imisebenzi yokukhanyisa ephezulu, izindleko zesistimu eziphansi kanye nezinzuzo zokutshala izimali ngokushesha. Ukubamba amakhono okuthulula ubuhlalu besibani se-LED esikhathini esizayo (i-LM yuan) ivelu. Ngomqondo othile, amakhono okugxilisa amalambu e-LED angamakhono okuthuthukisa nawokukhiqiza abakaki bokupakisha. I-COB LED isibani se-bead encapsulation kanye ne-single -chip LED isibani se-bead packaging iveze amandla amaningi mayelana nokukhanya okuqinile, ukuchithwa kokushisa, ukusatshalaliswa kokukhanya, izindleko, njll. Ubuhlalu belambu be-COB bendabuko be-LED manje buwubakaki osebenzisa ama-substrates e-aluminium (noma ithusi) ukuze ahlanganise ibhodi le-FR4 lefiber libe linye. Amaphilisi e-Domestic FR-4 semi-curing, i-thermal conductivity ingu-0.3/m-k kuphela, indlela yokungena engcono kakhulu ingu-2.0/m-k kuphela kumthengisi, kuyilapho i-coefficient yokushisisa ye-aluminium emsulwa ingu-237/m-k. Kumele ikhulise ukumelana nokushisa kwesistimu, okubangela ubuhlalu besibani se-LED obunzima ukuba bubole futhi bunciphise impilo yesevisi. Ngakho-ke, imibono yabantu engqondweni isusa i-fiber insulation ye-aluminium substrates. “Ubakaki we-LMCOB ”(Ukumba isikhumba sethusi kanye nongqimba oluvikelayo lwe-aluminium substrate), kodwa kunqunyelwe isizathu semishini, ijeli, inqubo kanye nezindleko, futhi akukakakhuthazwa. Ngaphezu kwalokho, imakethe yamanje ithandwa kakhulu okuthiwa “Umthombo wokukhanya ohlanganisiwe ”Isifundiswa, samukela inqubo yokubumba umjovo ukuze sifake ipuleti le-electrode ku-PPA (noma i-EMC ephushayo njengamanje), ngoba i-PPA izoba yimpushana ephuzi ngaphansi kwemisebe ye-ultraviolet efudumele, okuholela emanzini namanzi aphefumulayo. Isakhiwo kungenxa yokuthi ipuleti le-electrode liphakeme kune-chip 1.5 udade, futhi umthamo walo wempushana we-fluorescent kanye nejeli madala kakhulu. Ngeke nje kwandise izindleko zokupakisha, ama-colloid aminyene kakhulu azophinde athinte ukudlulisa. Njengamanje, bonke abakaki bobuhlalu belambu le-COB LED abanalo okuhlukile ekusetheni ukwakheka kwendawo evalekile ukuze kunqandwe izinsini ze-fluorescent ngaphandle kokuchitheka, ngenxa yokuthi ijeli yedamu kanye nokukhanya okungaphezulu okumunca uwoyela omhlophe. Ekuqaleni, ukuqina kokudluliswa kokukhanya nokushisa kwedolobha kuyisizathu esibalulekile somphumela wokukhanya wesikhashana womthombo wokukhanya wesibani sobuhlalu bendabuko be-COB LED kanye nobunzima bomphumela wokukhanya wesimo esiqinile. Ekwakheni ubuhlalu besibani se-LED, umbuzo ovame ukubuzwa welambu le-5052LED ukuthi ungakhetha kanjani ukunikezwa kwamandla okushayela, futhi empeleni ubuhlalu besibani se-LED buyawiswa noma bucekelwe phansi, futhi ingxenye yamandla okushayela inekhono. Ibhodi elifushane lokukhanyisa ubuhlalu obukhanyayo. Kodwa-ke, i-COB LED ubuhlalu be-aluminium substrates yamukele isakhiwo sokupakisha esihlukaniselwe amandla ashisayo, futhi (i-chip ichazwe ngokuqondile ku-substrate).
