"I-LED junction temperature" ayijwayelekanga kubantu abaningi, kodwa nakubantu abasembonini ye-LED! Manje ake sichaze ngokuningiliziwe. Lapho i-I-LED iyasebenza, izimo ezilandelayo zingakhuthaza izinga lokushisa lokuhlangana ukuthi likhuphuke ngamadigri ahlukahlukene.

I-1, Kufakazelwe yizinqubo eziningi ukuthi ukukhawulelwa kokuphuma kahle kokukhanya kuyisizathu esiyinhloko sokwanda kwezinga lokushisa le-junction ye-LED. Njengamanje, ukukhula kwezinto ezithuthukile kanye nobuchwepheshe bokukhiqiza ingxenye kungaguqula amandla kagesi amaningi okufakwayo abe amandla emisebe yokukhanya. Nokho, ngenxa yenkomba enkulu kakhulu ye-refractive yeI-chip ye-LEDimpahla uma kuqhathaniswa nendawo ezungezile, ama-photon amaningi (> 90%) akhiqizwe ku-chip awakwazi ukuchichima kahle isixhumi esibonakalayo, futhi ukuboniswa okuphelele kwenzeka kusixhumi esibonakalayo phakathi kwe-chip nendawo, Ibuyela ngaphakathi kwe-chip futhi igcine imuncwe. nge-chip material noma i-substrate ngokusebenzisa ukuboniswa okuningi kwangaphakathi, futhi iba ukushisa ngendlela yokudlidliza kwe-lattice, okuthuthukisa ukukhuphuka kwezinga lokushisa lokuhlangana.

2, Ngenxa yokuthi i-pn junction ayikwazi ukuphelela ngokwedlulele, ukusebenza kahle komjovo wesici ngeke kufinyelele ku-100%, okungukuthi, lapho i-LED isebenza, ngaphezu kokujova (imbobo) endaweni engu-n endaweni ye-P, i-n. Indawo izophinda ijove (i-electron) endaweni engu-P. Ngokuvamile, umjovo wokushaja wohlobo lwakamuva ngeke ukhiqize umphumela we-optoelectric, kodwa uzosetshenziswa ngendlela yokushisa. Ngisho nengxenye ewusizo yenkokhiso ejovwe ngeke yonke ibe lula, futhi enye izogcina iphenduka ukushisa uma ihlanganiswe nokungcola noma amaphutha endaweni yenhlukana.

3, Isakhiwo se-electrode esimpofu sesici, impahla ye-substrate yongqimba lwefasitela noma indawo yokuhlangana kanye neglue yesiliva eqhubayo konke kunenani elithile lokumelana. Lokhu kumelana kunqwabelene ukuze kwakhiwe ukumelana nochungechunge lweIsici se-LED. Lapho i-current igeleza ku-pn junction, izophinde igeleze kulaba baphikisi, okuholela ekushiseni kwe-Joule, okuholela ekwenyukeni kwezinga lokushisa le-chip noma izinga lokushisa lokuhlangana.

Yebo, ngokuthuthuka kwesayensi nobuchwepheshe, isizathu esiyinhloko esenza singakwazi ukuqonda lezi zenzakalo ezingenhla ngayinye ngayinye ukuthi ngeke siziqonde ngayinye ngayinye esikhathini esizayo. Yebo, ngeke siwaqonde ngamunye ngamunye ngentuthuko yesayensi nobuchwepheshe!
