Ubume kunye neempawu zezibane zesibane se-LED ikakhulu ziquka iitshiphusi ze-LED, izinto zokupakisha, iinkokeli, izinto zokuqhuba kunye nezinto zokuhambisa ukukhanya.
1. I-chip ye-LED: Inxalenye ephambili yezibane ze-LED yi-chip ye-LED, eyenziwe ngezinto ze-semiconductor. Iitshiphusi ze-LED zihlala ziqulunqwe ngohlobo lwe-P kunye nohlobo lwe-N-uhlobo lwezixhobo zesemiconductor. Xa unamandla, i-PN junction yenziwa phakathi kohlobo lwe-P kunye nohlobo lwe-N. Ukuhlawulelwa kwakhona kwentlawulo kufezekiswa ngokujova i-electron kunye nemingxuma, okubangelwa umphumo wesithombe sombane.
2. Izinto zokufaka i-encapsulation: Ii-chips ze-LED kufuneka zikhuselwe ngezinto ze-encapsulation. Izinto eziqhelekileyo zokufaka i-encapsulation ziquka i-epoxy resin, i-porcelain glue, i-silica gel, njl.
3. Ukukhokela: I-chip ye-LED kufuneka idibaniswe kwibhodi yesiphaluka, kwaye iinkokeli zidlala indima yokungenisa kunye nokuthumela ngaphandle kwemiqondiso yombane. Izinto eziqhelekileyo zokukhokela ziquka ucingo lwegolide kunye nocingo lobhedu. Intambo yegolide ine-conductivity elungileyo yombane kunye nokumelana nokubola.
4. Izinto zokuqhuba: Iintsimbi zesibane se-LED kufuneka zidlulisele izibonakaliso zombane kwi-chip ngokusebenzisa izinto zokuqhuba. Izinto zokuqhuba zidla ngokuba ziintsimbi, ezifana nesilivere, ubhedu okanye i-aluminiyam, ezinokusebenza kakuhle kombane kunye nokumelana nokubola.
5. Izinto eziguquguqukayo: Izibane zesibane se-LED zifuna izinto eziguquguqukayo ukuze kuphunyezwe ukukhanya. Izinto eziqhelekileyo eziguquguqukayo ziquka iplastiki kunye neglasi. Izinto zokuhambisa ukukhanya kufuneka zibe nokuhanjiswa kokukhanya okulungileyo kunye nokumelana ne-UV ukuze kuqinisekiswe umphumo wokuphuma kunye nomgangatho wokukhanya.
Iimpawu zesibane sesibane se-LED ziquka:
1. Ukusebenza okuphezulu kunye nokonga amandla: Izibane zesibane se-LED zinoguquko oluphezulu lwe-photoelectric. Xa kuthelekiswa nemithombo yokukhanya yendabuko, i-LED inokusetyenziswa kwamandla aphantsi, anokugcina amandla kunye nokunciphisa ukusetyenziswa kwamandla.
2. Ubomi obude: Izibane zesibane se-LED zinobomi obude, ngokuqhelekileyo zifikelela kumashumi amawaka eeyure, zidlula kude imithombo yokukhanya yendabuko.
3. Ukulungelelaniswa okulungileyo: Ubuhlalu besibane se-LED bunokutshintshwa kombala ngokweemfuno, kwaye banokufikelela kwiintlobo ezahlukeneyo zokushisa kombala kunye nokutshintsha ukukhanya.
4. I-Miniaturization kunye nofakelo olufanelekileyo: Ubuhlalu besibane se-LED buncinci ngobukhulu kunye ne-compact kwisakhiwo, kwaye zinokufakwa ngokulula kwaye zibekwe.
5. Ukumelana nokuzamazama okunamandla: Izibane zesibane se-LED zinokumelana nokuzamazama komhlaba kwaye awonakali lula.
6. Ukulungeleka kokusingqongileyo kunye nokungangcolisi: Amaso ezibane ze-LED aziqulathanga izinto ezinobungozi ezifana ne-mercury, zithobela iimfuno zokukhusela okusingqongileyo, kwaye aziyi kuvelisa ungcoliseko ngexesha lokusetyenziswa.
Ukushwankathela, izibane zezibane ze-LED zineempawu zokusebenza okuphezulu, ukonga amandla, ubomi obude, ukulungelelaniswa okuqinileyo, ukukhuselwa kwendalo kunye nokungangcolisi, ngoko ke zisetyenziswa ngokubanzi ekukhanyeni, ekuboniseni, ekuhombiseni kwangaphakathi kunye neemveliso ze-elektroniki kunye nezinye iinkalo.
Kukho konke, iteknoloji ye-LED iphumelele kakhulu ngokubhekiselele ekusebenziseni amandla, ixesha elide, ukuphuma kokukhanya kunye nokulawula. Ukusetyenziswa kwamandla aphantsi, ubomi obude, ukukhanya okuphezulu kunye nokusebenza ngokukhawuleza kwenza kube lukhetho oluhle kakhulu lokukhanyisa xa kuthelekiswa nezibane zendabuko kunye nezibane ze-fluorescent. Njengoko imfuno yokonga umbane kunye nezisombululo zokukhanya ezihambelana nokusingqongileyo ziqhubeka zikhula, iteknoloji ye-LED kulindeleke ukuba idlale indima ebalulekileyo ekubunjweni kwekamva lokukhanya.
