Namhlanje, xa isikrini sokubonisa i-LED sisetyenziswa ngokubanzi kwaye sisetyenziswa ngokubanzi, kufuneka siqonde ingqiqo eqhelekileyo yokugcinwa.Ingaba umboniso we-LED wangaphakathi okanye wangaphandle, ubushushu buveliswa ngexesha lokusebenza.Ke, ngaba ukusebenza kobushushu obuphezulu bomboniso we-LED kunawo nawuphi na umphumo?
Ngokubanzi, umboniso we-LED wangaphakathi unokukhanya okuphantsi, ngoko ke kukho ubushushu obuncinane, ngoko bukhupha ubushushu ngokwendalo.Nangona kunjalo, umboniso we-LED wangaphandle unokukhanya okuphezulu kwaye uvelisa ubushushu obuninzi, obufuna ukupholiswa yi-air conditioners okanye abalandeli be-axial.Ekubeni iyimveliso ye-elektroniki, ukunyuka kweqondo lokushisa kuya kuchaphazela ubomi bayo benkonzo.
1. Ukuba ukushisa okusebenzayo kwesiboniso se-LED kudlula ubushushu obuthwele umthwalo we-chip, ukukhanya okukhanyayo komboniso we-LED kuya kuncitshiswa, kuya kubakho ukuhla kokukhanya okucacileyo, kwaye umonakalo ungenzeka.Ukushisa okugqithisileyo kuya kuchaphazela ukuthotywa kokukhanya kwesikrini se-LED, kwaye kuya kubakho ukuthotywa kokukhanya.Oko kukuthi, njengoko ixesha lihamba, ukukhanya kuyehla ngokuthe ngcembe de kucime.Ubushushu obuphezulu ngoyena nobangela wokubola kokukhanya kunye nobomi obufutshane bomboniso.
Ukushisa kwe-2.Ukunyuka kuya kunciphisa ukusebenza okukhanyayo kwesikrini se-LED.Njengoko iqondo lokushisa linyuka, ukuxinwa kwee-electron kunye nemingxuma kwandisa, i-gap band iyancipha, kwaye ukuhamba kwe-electron kuncipha.Xa iqondo lobushushu linyuka, incopho eluhlaza okwesibhakabhaka yetshiphu itshintshela kwicala lamaza amaza amade, nto leyo ebangela ukuba i-wavelength yokukhutshwa kwe-chip kunye ne-excitation wavelength ye-phosphor ingahambelani, kunye nokusebenza kakuhle kokutsalwa kokukhanya ngaphandle kwesikrini se-LED esimhlophe siyancipha.Njengoko iqondo lokushisa liphakama, ukusebenza kwe-quantum ye-phosphor kuncipha, ukukhanya kuyancipha, kunye nokusebenza kakuhle kokukhanya kwangaphandle kwesikrini se-LED kunciphisa.
