Inkqubo yemvelisoIibhanti zezibane ze-LEDlikhonkco eliphambili kushishino lokukhanyisa i-LED. Ii-LED light beads, ezaziwa ngokuba zii-light emitting diodes, zizinto ezibalulekileyo ezisetyenziswa kwiindlela ezahlukeneyo zokukhanyisa ukusuka kwiindawo zokuhlala ukuya kwizisombululo zokukhanyisa iimoto nezemizi-mveliso. Kwiminyaka yakutshanje, ngenxa yeengenelo zokonga amandla, ubomi obude, kunye nokukhuselwa kwendalo kwee-LED lamp beads, imfuno yazo ikhule kakhulu, nto leyo ekhokelela kwinkqubela phambili kunye nokuphuculwa kwetekhnoloji yemveliso.
Inkqubo yokuvelisa ii-LED lamp beads ibandakanya amanqanaba amaninzi, ukusuka ekuvelisweni kwezinto ze-semiconductor ukuya ekuhlanganisweni kokugqibela kwee-LED chips. Inkqubo iqala ngokukhethwa kwezinto ezicocekileyo kakhulu ezifana ne-gallium, i-arsenic, kunye ne-phosphorus. Ezi zinto zidityaniswe ngomlinganiselo ochanekileyo ukwenza iikristale ze-semiconductor ezakha isiseko setekhnoloji ye-LED.
Emva kokuba izinto ze-semiconductor zilungisiwe, zidlula kwinkqubo yokucoca engqongqo ukuze zisuse ukungcola kwaye ziphucule ukusebenza kwazo. Le nkqubo yokucoca iqinisekisa ukuba iintsimbi zesibane se-LED zibonelela ngokukhanya okuphezulu, ukuhambelana kombala, kunye nokusebenza kakuhle xa zisetyenziswa. Emva kokucoca, izinto zinqunyulwa zibe zii-wafers ezincinci kusetyenziswa isixhobo sokusika esiphucukileyo.
Inyathelo elilandelayo kwinkqubo yemveliso libandakanya ukwenziwa kweetships ze-LED ngokwazo. Ii-wafers ziphathwa ngononophelo ngeekhemikhali ezithile kwaye zidlule kwinkqubo ebizwa ngokuba yi-epitaxy, apho iileya zezinto ze-semiconductor zifakwa phezu komphezulu we-wafer. Olu dawo lwenziwa kwindawo elawulwayo kusetyenziswa iindlela ezifana ne-metal-organic chemical vapor deposition (MOCVD) okanye i-molecular beam epitaxy (MBE).
Emva kokuba inkqubo ye-epitaxial igqityiwe, i-wafer kufuneka idlule kuthotho lwamanyathelo e-photolithography kunye nokukrola ukuze kuchazwe ulwakhiwo lwe-LED. Ezi nkqubo ziquka ukusetyenziswa kweendlela eziphambili ze-photolithography ukwenza iipateni ezintsonkothileyo kumphezulu we-wafer ezichaza izinto ezahlukeneyo ze-chip ye-LED, njengeendawo ze-p-type kunye ne-n-type, iileya ezisebenzayo, kunye nee-contact pads.
Emva kokuba iitshiphusi ze-LED zenziwe, zidlula kwinkqubo yokuhlela nokuvavanya ukuqinisekisa umgangatho kunye nokusebenza kwazo. Itshiphusi ivavanywa iimpawu zombane, ukukhanya, ubushushu bombala, kunye nezinye iiparameter ukuze kuhlangatyezwane nemigangatho efunekayo. Iitshiphusi ezineengxaki ziyahlelwa ngelixa iitshiphusi ezisebenzayo zisiya kwinqanaba elilandelayo.
Kwinqanaba lokugqibela lemveliso, iitships ze-LED zipakishwa kwiibhile zokugqibela zezibane ze-LED. Inkqubo yokupakisha ibandakanya ukufaka iitships kwisakhelo se-lead, ukuzidibanisa noonxibelelwano bombane, kunye nokuzigquma ngezinto ezikhuselayo ze-resin. Olu pakisho lukhusela itships kwizinto ezingqongileyo kwaye lonyusa ukuqina kwayo.
Emva kokupakishwa, ii-LED lamp beads zivavanywa ngakumbi ngokusebenza, ukuqina, kunye nokuthembeka. Ezi mvavanyo zilinganisa iimeko zokusebenza zokwenyani ukuqinisekisa ukuba ii-LED lamp beads zisebenza ngokuzinzileyo kwaye zinokumelana neemeko ezahlukeneyo zokusingqongileyo ezifana nokuguquguquka kobushushu, ukufuma, kunye nokungcangcazela.
Lilonke, inkqubo yokuvelisa iintsimbi zezibane ze-LED iyinkimbinkimbi kakhulu, ifuna oomatshini abaphambili, ulawulo oluchanekileyo, kunye nokuhlolwa komgangatho okungqongqo. Ukuqhubela phambili kwitekhnoloji ye-LED kunye nokwenza ngcono iinkqubo zemveliso kube negalelo elikhulu ekwenzeni izisombululo zokukhanyisa ze-LED zibe namandla angcono, zihlale ixesha elide, kwaye zithembeke. Ngophando oluqhubekayo kunye nophuhliso kweli candelo, inkqubo yokuvelisa kulindeleke ukuba iphuculwe ngakumbi, kwaye iintsimbi zezibane ze-LED ziya kuba zisebenza kakuhle kwaye zifikeleleke ngakumbi kwixesha elizayo.
Ukuba unomdla kwinkqubo yokuvelisa ii-LED lamp beads, wamkelekile ukuba uqhagamshelane nomenzi wezibane zesitalato ze-LED uTIANXIANG ukuze akuncede.Funda ngokugqithisileyo.
