Kubuchwepheshe banamuhla obuthuthuka ngokushesha, izibonisi ze-LED seziye zanda kakhulu ezikrinini ezibalulekile zasemadolobheni, ezinkundleni zemidlalo yasekhaya, ekudlaleni kwesiteji, nokuningi, okuthandwa kakhulu ngenxa yokukhanya kwazo okuphezulu nemiphumela yemibala egqamile. Ngemuva kwalokhu okuhlangenwe nakho okumangalisayo okubonakalayo, izinto ezingavamile zomhlaba zidlala indima ebalulekile engenakuphikwa.
Izinto zomhlaba ezingavamile aziqanjwanga ngenxa yokuntuleka kodwa ngenxa yobunzima bokuzikhipha nokuzihlukanisa. Ngezakhiwo zazo eziyingqayizivele zomzimba nezamakhemikhali, lezi zinto sezibe “yisikhali esiyimfihlo” sokuthuthukisa ukusebenza kwesibonisi se-LED.
Ukusebenzisa i-Rare earth doping kuthuthukisa kakhulu ukusebenza kahle kokukhanya. Ngokwethula izinto ezithileumhlaba ongavamile izakhi zibe ama-LED aluhlaza okwesibhakabhaka, akugcini nje ngokuthuthukisa ukusebenza kahle kokukhanya futhi kunciphisa i-voltage yokushayela kodwa futhi kwandisa isikhathi sokuphila kwe-LED.Lokhu kusho ukuthi izibonisi ze-LED zisebenza kahle kakhulu futhi zingabizi kakhulu ekunakekelweni
Izinto zomhlaba ezingavamile futhi kuvelele ekwenzeni ngcono izici ze-LED spectral. Ukusebenzisa i-doping nge-rare earths kwenza ukukhanya okukhishelwayo kusondele ekukhanyeni kwemvelo, kuthuthukisa ukunemba kombala futhi kudale isipiliyoni sokubona esikhululekile. Kungakhathaliseki ukuthi ukusakaza amavidiyo anencazelo ephezulu noma ukukhanyisa kwesiteji okukhazimulayo, i-rare earths yenza izithombe zikhanye futhi zibe ngokoqobo.
Ngaphezu kwalokho, ama-rare earths azinzisa izinga lokushisa lombala we-LED ngendlela emangalisayo. Ngaphansi kwamazinga okushisa ahlukene kanye nomswakama, ama-rare earth-doped LED agcina izinga lokushisa lombala elifanayo, eqinisekisa ukuthi izibonisi azifiphali noma zishintshashintsha umbala.
Ezinye izindawo ezingavamile ezifana i-cerium (i-Ce)kanye ne-europium (Eu) kuthuthukisa ukukhanya okukhanyayo ngokumunca ukukhanya okuluhlaza okwesibhakabhaka bese kuguqula kube ukukhanya okuphuzi, okwenza izibonisi zibonakale kahle ngisho nasekukhanyeni okunamandla kwangaphandle.
Okuphawulekayo ukuthi ukusebenzisa i-rare earth doping kuthuthukisa ukumelana nemisebe yama-LED aluhlaza okwesibhakabhaka, kunciphisa izingozi zokulimala kwemisebe, futhi kunciphisa amazinga okushisa okusebenza, kuvimbele ukuwohloka kokusebenza kanye nokuncipha kwesikhathi sokuphila okubangelwa ukushisa ngokweqile.
Njengoba ubuchwepheshe buqhubeka,izinhlelo zokusebenza zomhlaba ongavamileizibonisi ze-LED zizojula. Esikhathini esizayo, singalindela izibonisi ze-LED ezisebenzisa amandla amaningi, ezicacile, nezizinzile, eziletha imiphumela emihle.e kuyashaqisa amadili abonakalayo. Ngemuva kwakho konke, izinto zomhlaba ezingavamile izoqhubeka nokukhulula inani layo eliyingqayizivele njengamandla ashukumisayo kubuchwepheshe bokubonisa.
