Uma i-LED isebenza, izimo ezilandelayo zingenza izinga lokushisa lenhlanganiso likhuphuke liye kumazinga ahlukahlukene.

I-1, Kufakazelwe ukuthi ukukhawulelwa kokusebenza kahle okukhanyayo kuyisizathu esiyinhloko sokukhuphuka kweI-junction ye-LEDizinga lokushisa. Njengamanje, ukukhula kwezinto ezithuthukile kanye nezinqubo zokukhiqiza izingxenye zingaguqula amandla kagesi amaningi okufakwayoI-LED ibe ukukhanyaamandla emisebe. Kodwa-ke, ngenxa yokuthi izinto ze-chip ze-LED zinama-coefficients e-refractive amakhulu kakhulu kunemidiya ezungezile, ingxenye enkulu yama-photon (>90%) akhiqizwe ngaphakathi kwe-chip ayikwazi ukuchichima kahle isixhumi esibonakalayo, futhi ukuboniswa okuphelele kukhiqizwa phakathi kwe-chip nesixhumi esibonakalayo semidiya, ibuyela ngaphakathi kwe-chip futhi ekugcineni imuncwe yi-chip material noma i-substrate ngokusebenzisa ukuboniswa okuningi kwangaphakathi, futhi ishisa ngendlela yokudlidliza kwe-lattice, okuthuthukisa izinga lokushisa lokuhlangana ukuthi likhuphuke.

2, Njengoba ukuhlangana kwe-PN kungeke kube okuphelele ngokwedlulele, ukusebenza kahle komjovo wesici ngeke kufinyelele ku-100%, okungukuthi, ngaphezu kokushaja (imbobo) ejovelwe endaweni engu-N endaweni engu-P, indawo engu-N nayo izojova. shaja (i-electron) endaweni engu-P lapho i-LED isebenza. Ngokuvamile, uhlobo lokugcina lomjovo wokushaja ngeke lukhiqize umphumela we-optoelectric, kodwa luzosetshenziswa ngendlela yokufudumeza. Ngisho noma ingxenye ewusizo yenkokhiso ejovwe ingabi lula yonke, enye izogcina iba ukushisa uma ihlanganiswa nokungcola noma amaphutha endaweni yokuhlangana.

I-3, Isakhiwo se-electrode esibi sesici, izinto zokwakha ze-substrate yongqimba lwefasitela noma indawo yokuhlangana, kanye neglue yesiliva eqhubayo konke kunamanani athile okumelana. Lokhu kumelana kunqwabelene komunye nomunye ukwenza ukumelana nochungechunge lweIsici se-LED. Lapho i-current igeleza ku-junction ye-PN, izophinde igeleze ngalawa ma-resistors, okuholela ekushiseni kwe-Joule, okuzoholela ekukhuphukeni kwezinga lokushisa le-chip noma izinga lokushisa lokuhlangana.
