Inqubo yokukhiqiza ubuhlalu bezibani ze-LED

Inqubo yokukhiqizaUbuhlalu besibani se-LEDiyisixhumanisi esibalulekile embonini yokukhanyisa i-LED. Ubuhlalu bokukhanya be-LED, obaziwa nangokuthi ama-diode akhipha ukukhanya, buyizinto ezibalulekile ezisetshenziswa ezinhlobonhlobo zezicelo kusukela ekukhanyeni kwezindlu kuya kuzixazululo zokukhanyisa zezimoto nezezimboni. Eminyakeni yamuva nje, ngenxa yezinzuzo zokonga amandla, impilo ende, kanye nokuvikelwa kwemvelo kwamahlalu okukhanya kwe-LED, isidingo sawo sikhule kakhulu, okuholela entuthukweni nasekuthuthukisweni kobuchwepheshe bokukhiqiza.

Inqubo yokukhiqizwa kwama-LED lamp beads ihilela izigaba eziningi, kusukela ekukhiqizweni kwezinto ze-semiconductor kuya ekuhlanganisweni kokugcina kwama-LED chips. Inqubo iqala ngokukhethwa kwezinto ezihlanzekile kakhulu njenge-gallium, i-arsenic, ne-phosphorus. Lezi zinto zihlanganiswa ngezilinganiso eziqondile ukuze kwakhiwe amakristalu e-semiconductor akha isisekelo sobuchwepheshe be-LED.

Ngemva kokuba izinto ze-semiconductor sezilungisiwe, zidlula enkambisweni yokuhlanza eqinile ukuze kususwe ukungcola futhi kuthuthukiswe ukusebenza kwazo. Le nqubo yokuhlanza iqinisekisa ukuthi ubuhlalu bezibani ze-LED bunikeza ukukhanya okuphezulu, ukuhambisana kombala, kanye nokusebenza kahle uma kusetshenziswa. Ngemva kokuhlanza, izinto zinqunywa zibe ama-wafer amancane kusetshenziswa umshini wokusika othuthukisiwe.

Isinyathelo esilandelayo enkambisweni yokukhiqiza sihilela ukudalwa kwama-chip e-LED ngokwawo. Ama-wafer aphathwa ngokucophelela ngamakhemikhali athile futhi adlula enkambisweni ebizwa ngokuthi i-epitaxy, lapho izendlalelo zezinto ze-semiconductor zifakwa khona phezu kwe-wafer. Lokhu kufakwa kwenziwa endaweni elawulwayo kusetshenziswa amasu anjenge-metal-organic chemical vapor deposition (MOCVD) noma i-molecular beam epitaxy (MBE).

Ngemva kokuba inqubo ye-epitaxial isiqediwe, i-wafer idinga ukudlula ochungechungeni lwezinyathelo ze-photolithography kanye nokuqopha ukuze kuchazwe isakhiwo se-LED. Lezi zinqubo zihilela ukusetshenziswa kwamasu e-photolithography athuthukisiwe ukudala amaphethini ayinkimbinkimbi ebusweni be-wafer achaza izingxenye ezahlukene ze-chip ye-LED, njengezifunda ze-p-type kanye ne-n-type, izendlalelo ezisebenzayo, kanye nama-contact pads.

Ngemva kokuba ama-chip e-LED ekhiqizwe, adlula enkambisweni yokuhlunga nokuhlola ukuqinisekisa ikhwalithi nokusebenza kwawo. I-chip ihlolwa izici zikagesi, ukukhanya, izinga lokushisa lombala, kanye neminye imingcele ukuze kuhlangatshezwane nezindinganiso ezidingekayo. Ama-chip anephutha ayahlelwa ngenkathi ama-chip asebenzayo eya esigabeni esilandelayo.

Esigabeni sokugcina sokukhiqizwa, ama-chip e-LED afakwa kuma-lamp bead okugcina e-LED. Inqubo yokufaka ihilela ukufaka ama-chip ohlakeni lwe-lead, ukuwaxhumanisa nokuxhumana kukagesi, nokuwafaka entweni evikelayo ye-resin. Lokhu kupakisha kuvikela i-chip ezintweni zemvelo futhi kwandisa ukuqina kwayo.

Ngemva kokupakishwa, ubuhlalu bezibani ze-LED buhlolwa okwengeziwe ngokusebenza, ukuqina, kanye nokuthembeka. Lokhu kuhlolwa kulingisa izimo zokusebenza zangempela ukuqinisekisa ukuthi ubuhlalu bezibani ze-LED busebenza kahle futhi bungamelana nezici ezahlukahlukene zemvelo njengokushintshashintsha kwezinga lokushisa, umswakama, kanye nokudlidliza.

Sekukonke, inqubo yokukhiqiza ubuhlalu bezibani ze-LED iyinkimbinkimbi kakhulu, idinga imishini ethuthukisiwe, ukulawulwa okunembile, kanye nokuhlolwa kwekhwalithi okuqinile. Intuthuko kwezobuchwepheshe be-LED kanye nokwenza ngcono izinqubo zokukhiqiza kube negalelo elikhulu ekwenzeni izixazululo zokukhanyisa ze-LED zisebenzise kahle amandla, ziqine, futhi zithembeke. Ngocwaningo oluqhubekayo kanye nentuthuko kulo mkhakha, inqubo yokukhiqiza kulindeleke ukuthi ithuthukiswe kakhulu, futhi ubuhlalu bezibani ze-LED buzosebenza kahle futhi bube shibhile esikhathini esizayo.

Uma unesifiso senqubo yokukhiqiza ubuhlalu bezibani ze-LED, wamukelekile ukuxhumana nomkhiqizi wezibani zasemgwaqweni ze-LED uTIANXIANG ukuzeFunda kabanzi.
