Ubuchwepheshe be-chip obuyingqayizivele, usinki wokushisa wekhwalithi ephezulu, kanye nomzimba wesibani se-premium aluminium kuqinisekisa ngokugcwele impiloIzibani ze-LED zezimboni, enesilinganiso sokuphila kwe-chip samahora angu-50,000. Kodwa-ke, abathengi bonke bafuna ukuthenga kwabo kuqhubeke isikhathi eside, futhi izibani zezimboni ze-LED nazo zihlukile. Ngakho-ke isikhathi sokuphila sezibani zezimboni ze-LED singathuthukiswa kanjani? Okokuqala, lawula ngokuqinile ikhwalithi yezinto zokupakisha izibani zezimboni ze-LED, njenge-adhesive conductive, abicah, phosphor, epoxy, izinto zokubopha ezifayo, nama-substrates. Okwesibili, ukuklama ngokunengqondo isakhiwo sokupakisha isibani sezimboni ze-LED; isibonelo, ukupakisha okungenangqondo kungabangela ukucindezeleka nokuphuka. Okwesithathu, ukuthuthukisa inqubo yokukhiqiza izibani zezimboni ze-LED; isibonelo, izinga lokushisa lokuphulukisa, i-pressure welding, ukubeka uphawu, i-die bonding, kanye nesikhathi kufanele konke kulandelwe ngokuqinile ngokuvumelana nezidingo.
Ukuze uthuthukise isikhathi sokuphila sezinsiza zamandla omshayeli wezibani zezimboni ze-LED, ukukhetha izinga eliphezulu, ama-capacitor ahlala isikhathi eside kuyindlela ephumelelayo yokuthuthukisa isikhathi sokuphila kwamandla omshayeli; ukunciphisa i-ripple current kanye ne-voltage yokusebenza egeleza nge-capacitor; ukuthuthukisa ukusebenza kahle kokushayela kokunikezwa kwamandla; ukunciphisa ukumelana nokushisa kwengxenye; sebenzisa ukuvimbela amanzi nezinye izindlela zokuzivikela; futhi unake ukukhethwa kwama-adhesives conductive thermally.
Ikhwalithi yomklamo wokukhipha ukushisa iyisici esibalulekile esikhathini sokuphila sezibani zezimayini ze-LED. Abantu abaningi bakhathazeka ngokuthi izibani ze-LED zamandla aphezulu zimane “zikhanya ngokwesabekayo” kodwa zizolulaza ngokushesha noma zehluleke. Eqinisweni, umthelela wangempela wokuphila usekuklameni kokukhipha ukushisa nekhwalithi yomthombo wokukhanya. Ezimweni ezifana nezindawo zokusebenzela lapho ukusebenza kunwetshwa khona, uma isibani singakwazi ukuqeda ukushisa ngempumelelo, ukuguga kwe-chip kuzosheshisa, futhi ukukhanya kuzokwehla ngokushesha. Izinhlaka ze-aluminium alloy fin zisetshenziswa ezimbonini nezilambu zezimayini ezisezingeni eliphezulu ukuze kuthuthukiswe ukushintshwa komoya, ukugcina izingxenye eziyinhloko ngaphakathi kwebanga lokushisa elifanele nokwelula ukuphila kwazo. Ukuphila kwamalambu anemiklamo ehlukene kungahluka kakhulu, ngezinye izikhathi izikhathi ezingamashumi, ngisho nalapho kusetshenziswa ama-chips ekhwalithi afanayo. Ngenxa yalokho, uhlelo lokukhipha ukushisa kwesibani lubalulekile ekwakhiweni kwaso. Ukukhishwa kokushisa kwe-LED ngokuvamile kufaka phakathi ukuchithwa kokushisa kwezinga lesistimu kanye nokuchithwa kokushisa kwephakheji. Zombili izinhlobo zokushisa ukushisa kufanele zicatshangelwe ngesikhathi esifanayo ukuze kuncishiswe ukumelana nokushisa kwesibani. Ngesikhathi sokukhiqizwa kwemithombo yokukhanya ye-LED, izinto zokupakisha, izakhiwo zokupakisha, nezinqubo zokukhiqiza zenzelwe ukufeza ukuchithwa kokushisa kwezinga lephakheji.
Njengamanje, izinhlobo eziyinhloko zemiklamo yokuqothula ukushisa zifaka izakhiwo ze-flip-chip ezisekelwe ku-silicon, izakhiwo zebhodi lesifunda sensimbi, nezinto ezifana ne-die-bonding materials nama-epoxy resins. Ukukhishwa kokushisa kweleveli yesistimu ngokuyinhloko kubandakanya ucwaningo lobuchwepheshe obufanele ukuze kusungulwe izinto ezintsha nokuthuthukisa amasinki okushisa. Ngokudlanga okwandayo kwama-LED anamandla amakhulu, ukuphuma kwamandla nakho kuyenyuka. Njengamanje, ukuchithwa kokushisa kweleveli yesistimu ikakhulukazi kusebenzisa izindlela nezakhiwo ezifana nokupholisa ugesi we-thermoelectric, ukupholisa amapayipi okushisa, nokupholisa umoya ngempoqo. Ukuxazulula inkinga yokushisa ukushisa kuyindlela ephumelelayo yokuthuthukisa isikhathi sokuphila sezibani zezimayini ze-LED, ngaleyo ndlela kudinga ucwaningo olwengeziwe kanye nokusha.
Njengoba izinhlelo ezihlukahlukene zokukhanyisa zasefekthri naseworkshop ziqhubeka nokuthuthukiswa futhi zithuthukiswa, umphumela wokonga amandla wezibani zezimboni nezazimayini uya ngokuya ubonakala, okuholela ekutheni izitshalo eziningi zezimboni zizikhethe njengezinto zazo zokukhanyisa. I-TIANXIANG igxile ocwaningweni, ekuthuthukisweni, ekukhiqizeni, ekuthengisweni nasekusebenzeleni izibani zasemgwaqweni ze-LED, izibani zezimayini ze-LED, kanyeIzibani zengadi ze-LED, ukuhlinzeka ngekhwalithi ephezulu, ukusebenza okuphezuluImikhiqizo yohlelo lokusebenza lwe-LED.
