Isakhiwo kanye nezici zobuhlalu bezibani ze-LED ikakhulukazi zihlanganisa ama-chips e-LED, izinto zokupakisha, umkhondo, izinto zokuqhuba kanye nezinto zokudlulisa ukukhanya.
1. I-chip ye-LED: Ingxenye eyinhloko yobuhlalu besibani se-LED yi-chip ye-LED, eyenziwe ngezinto zokwakha ze-semiconductor. Ama-chips e-LED ngokuvamile akhiwa uhlobo lwe-P kanye ne-N-type semiconductor materials. Uma inikwe amandla, ukuhlangana kwe-PN kwakheka phakathi kohlobo lwe-P nohlobo lwe-N. I-Charge recombination ifinyelelwa ngokujova ama-electron nezimbobo, okuholela kumphumela we-photoelectric.
2. Izinto zokufaka i-encapsulation: Ama-chips e-LED adinga ukuvikelwa ngezinto zokuhlanganisa. Izinto ezivamile zokufaka i-encapsulation zihlanganisa i-epoxy resin, i-porcelain glue, i-silica gel, njll. Izinto zokupakisha zinganikeza ukuvikelwa nokulungiswa kwe-chip, futhi inezinto ezithile zokushisa ezishisayo kanye nezindawo zokumelana nokushisa.
3. Ukuhola: I-chip ye-LED idinga ukuxhunywa ebhodini lesifunda, futhi umkhondo udlala indima yokungenisa nokukhipha amasignali kagesi. Izinto ezijwayelekile zokuhola zihlanganisa intambo yegolide nocingo lwethusi. Intambo yegolide ine-conductivity enhle kagesi kanye nokumelana nokugqwala.
4. Izinto ezisetshenziswayo: Ubuhlalu besibani se-LED budinga ukudlulisa amasignali kagesi ku-chip ngokusebenzisa izinto zokuqhuba. Izinto ezisetshenziswayo ngokuvamile ziyizinsimbi, njengesiliva, ithusi noma i-aluminium, ezinokusebenza kahle kukagesi nokungagqwali.
5. Izinto ezikhanyayo: Ubuhlalu besibani se-LED budinga izinto ezikhanyayo ukuze kuzuzwe ukuphuma kokukhanya. Izinto ezivamile ezishintshashintshayo zihlanganisa ipulasitiki nengilazi. Izinto zokudlulisa ukukhanya zidinga ukudluliswa kokukhanya okuhle kanye nokumelana ne-UV ukuze kuqinisekiswe umphumela wokuphuma kanye nekhwalithi yokukhanya.
Izici zobuhlalu besibani se-LED zifaka:
1. Ukusebenza kahle okuphezulu nokonga amandla: Ubuhlalu besibani se-LED busebenza kahle kakhulu ekuguquleni i-photoelectric. Uma kuqhathaniswa nemithombo yokukhanya evamile, i-LED inokusetshenziswa kwamandla okuphansi, okungagcina amandla futhi kunciphise ukusetshenziswa kwamandla.
2. Impilo ende: Ubuhlalu besibani se-LED buphila isikhathi eside, ngokuvamile bufinyelela amashumi ezinkulungwane zamahora, okudlula kude imithombo yokukhanya evamile.
3. Ukulungiswa okuhle: Ubuhlalu besibani se-LED bungashintshwa umbala ngokuya ngezidingo, futhi bungafinyelela izinga lokushisa elihlukahlukene lombala kanye nezinguquko zokukhanya.
4. I-Miniaturization kanye nokufakwa okulula: Ubuhlalu besibani se-LED buncane ngosayizi futhi buhlangene ngesakhiwo, futhi bungafakwa kalula futhi bubekwe.
5. Ukumelana nokuzamazama komhlaba okuqinile: Ubuhlalu besibani se-LED bunokumelana okuhle nokuzamazama komhlaba futhi abubonakali kalula.
6. Ayinabungani nendawo ezungezile futhi ayingcolisi: Ubuhlalu besibani se-LED abuqukethe izinto eziyingozi njenge-mercury, buthobelana nezidingo zokuvikela imvelo, futhi ngeke bukhiqize ukungcola ngesikhathi sokusetshenziswa.
Ukufingqa, ubuhlalu besibani se-LED bunezici zokusebenza kahle kakhulu, ukonga amandla, impilo ende, ukulungiswa okuqinile, ukuvikelwa kwemvelo nokungangcoli, ngakho-ke asetshenziswa kabanzi ekukhanyiseni, ekuboniseni, ekuhlobiseni kwangaphakathi kanye nemikhiqizo ye-elekthronikhi neminye imikhakha.
Sekukonke, ubuchwepheshe be-LED busebenza kahle kakhulu mayelana nokusetshenziswa kwamandla, ukuphila isikhathi eside, ukuphuma kokukhanya nokulawula. Ukusetshenziswa kwayo okuphansi kwamandla, impilo ende, ukukhanya okuphezulu kanye nokusebenza okukhanyayo kuyenza ibe ukukhetha okuhle kakhulu kokukhanyisa uma kuqhathaniswa nezibani zendabuko ze-incandescent kanye ne-fluorescent. Njengoba isidingo sezixazululo zokukhanyisa ezonga amandla nemvelo sikhula, ubuchwepheshe be-LED kulindeleke ukuthi bubambe iqhaza elibaluleke kakhulu ekulolongeni ikusasa lokukhanyisa.
